This article shortly introduces 3D printers and provides some advice on selecting a printer and then lists cheap open source and commercial 3D printers. '''However''' I won't try to update this list very much. Some day I probably kill most entries and just list a few models that are typical for a given kind. Other web sites have more man power to do comparisons. [[User:Daniel K. Schneider|Daniel K. Schneider]] ([[User talk:Daniel K. Schneider|talk]]) 02:32, 3 February 2016 (CET)
This article shortly introduces 3D printers and provides some advice on selecting a printer. The original article, created many years ago, listed many printers, but I stopped upgrading systematically around 2016. The [Https://edutechwiki.unige.ch/mediawiki/index.php%3Ftitle%3D3D%20printer%26oldid%3D74536 old version] is still around. There are no endorsements, since I only owned a RapMan (2010), a [[Fabbster 3D printer|fabbster]] (given away), a Creality (2015, given away), four different [[:category:Felix 3D printer|Felix printers (1.0, 2.2, Pro2 and Tec4.1]] (I still use the latter two), a [[Fokoos Odin-5 F-3]] (2022, bought for 200 Euros on sale) and a [[:fr:Creality K1 Max 3D printer|Creality K1 Max]]. I also use Prusa mini and I3 printers in our fablab.


According to [http://en.wikipedia.org/wiki/3D_printing Wikipedia], retrieved 14:48, 14 October 2011 (CEST), {{quotation|3D printing is a form of [http://en.wikipedia.org/wiki/Additive_manufacturing additive manufacturing technology] where a three dimensional object is created by laying down successive layers of material. 3D printers are generally faster, more affordable and easier to use than other additive manufacturing technologies. 3D printers offer product developers the ability to print parts and assemblies made of several materials with different mechanical and physical properties in a single build process. Advanced 3D printing technologies yield models that can serve as product prototypes.}}
According to [https://en.wikipedia.org/wiki/3D_printingn Wikipedia], retrieved 11 April 2023, 3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model.[1] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control,[2] with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

The three most popular 3D printing techniques are:
The most popular 3D printing techniques are:
* [http://en.wikipedia.org/wiki/Fused_deposition_modeling fused deposition modeling], also called Fused Filament Fabrication (FFF). A typical example are low cost models like the [[RapMan]]
* [https://en.wikipedia.org/wiki/Fused_filament_fabrication#Fused_deposition_modeling Fused deposition modeling] ('''FDM)''', also called Fused Filament Fabrication (FFF). A typical example of the first available low cost kit that required a few days of assembly was the [[RapMan]]. As of 2023, entry level printers are cheap (around 300 Euros) and are assembled fairly quickly. Consumer-grade quality machines cost around 1000.

SLA machines use a laser to harden selected areas.
* DLP (Digital Light Processing) works, like SLA, with resin. As opposed to a laser that will solidify very specific areas, a DLP printer projects an image onto the pool of resin which then hardens each layer, one at a time.

Most hobby 3D printers use FFF, i.e. an extruder (i.e. a kind of gun) that heats up plastic filament which is then deposited layer by layer. They can print different sorts of Polymers. In the early years, the two following plastics were popular.

* Support for multiple types of plastic, in particular PLA but also some strong plastics like ABS or Nylon (for some, this is a must-have feature).

* A wide printing area (as wide as the objects you plan to print). 25x25x25 is OK as of 2023.
To do:
* produce some specifications for each model
* have some indication on how well these model operate. Speed, print size, resolution is not everything. An important criteria is knowing whether you can leave your printer alone. Many require constant attendance, because of filament intake problems for example.

On of the first serious comparisons was done by [http://blog.makezine.com/volume/make-ultimate-guide-to-3d-printing/ Make Mag] in nov 2012. One of my printers (the Felixprinter 1.0) came out ok. Nevertheless the author complained about assembly that was more difficult than expected and glitches with some delivered parts (like calibration of the stepper motors) and he is right to do that. However, why compare a non-assembled printer with assembled ones. I bought mine ''assembled'' (400 Euros extra) and it worked out of the box! In addition, the testers used default settings of the slicer software. Had they '''selected a different profile''' they would have obtained widely different results. I was able to print a test design that failed without problems. The Make Mag test was serious, but far from perfect. - [[User:Daniel K. Schneider|Daniel K. Schneider]] 17:53, 22 November 2012 (CET)

Do not trust marketing hype. In particular, some commercial printers make disputable claims and some even do not work well. Of course, other commercial models do work very well. Ask around if you know people in your area. In any case, filament printers do have inherent flaws that no design can solve...
Do not trust marketing hype. In any case, filament printers do have inherent flaws that no design can solve. Only trust reputable online sites (most receive something in exchange for rewiewing). Also, understand that some cheap printers start degrading after a few weeks and that others have poor quality assurance (i.e. some machines work fine but others need to repaired when you open the box).
 
== Fast 2023 FDM machines ==
I am looking into these models right now and may buy one. By the end of 2022 very fast "coreXY" FDM printers did appear on the market or were announce for Q2 or Q3 of 2023. An other options are IDEX printers where two extruders can work at the same time on copied or mirrored ''same'' objects. Since Summer 2023, fast "bed slingers" like the cheap Kobra 2 from Anycubic did appear.
 
Since I hate waiting a full day for a moderately large bag of LEGO or DUPLO compatible bricks I am interesting in getting one of these model and would print with a 0.6mm nozzle or larger.
 
Some of these printers may require minor modifications, e.g. better PEI print plates (e.g. read [https://de.aliexpress.com/item/1005004822611074.html this] for the Bambu) or better nozzles. All probably require verification and some tuning after the transport.

** Print area: 27 x 20.5 x 21 cm, not heated platform
** 3mm nozzle
** Resolution: x&y axis = 0.2mm, z axis = 0.7mm (roughly)
** [http://www.rap-man.com/ A1 Technologies] is a UK reseller
** Materials: ABS (warping for bottom surfaces larger than 4-5cm), PLA of various sorts.
** The Rapman was one of the first commercial kits for the RepRap v1 and it's probably one of the most beautiful designs. Assembly is rather difficult, but very well documented. All you needed was good reading skills. It works well, but does need what we could call "RepRap printing skills". Some design elements could be improved, in particular: filament intake (extruder), connectivity (USB instead of a SD card), portability (after transport the structure may need adjustment), (optional) heated platform. The commercial 3D Touch solves some of these problems.
* [http://www.bitsfrombytes.com/catalog/3dtouch 3DTouch 3D Printer] was an assembled 3D printer and costs £1,995.00 (single head) or £2,245.00 (double head).  The [http://www.bitsfrombytes.com/store/bfb-3dtouch-3d-printer-education-pack Education pack] (£2,484.00) included double head and plastic rolls. This model seems to be the successor of the BFB 3000 (or the same design ?). It includes "industrial" parts, i.e. it's rumored to be reliable.
** Resolution: same as RapMan v3.11


Unfortunately, 3D systems killed all the forums and the wiki which did include valuable information for other people using other 3D printers (www.bitsfrombytes.com/forum Forum and wiki.bitsfrombytes.com) or maybe I just can't find them.

== Commercial closed design entry-level filament 3D printers ==
== Web services for 3D printing ==
 
We distinguish between commercial 3D printers that are closed source (below) and commercial open source/open design printers (in the previous section). An other '''very''' important distinction is between closed design printers that are open to modification and use standard boards (e.g. Arduino), standard g-code, open-source slicers and control software (such as the Felix) as opposed to printers that will rely on proprietary boards, g-code, slicer and control software (such as the fabbster). Personally I like the combination of commercial (the printer) and open (software, spare parts that can be printed, standard filament) as opposed to printers that require special plastic, special software, special hardware. A bit like Android as opposed to the iThings ....
 
As of december 2011, we counted two fully assembled machines and two announcement for kits. By summer 2012, there were more and one could buy a commercial printer kit for around 1000 Euros or less. See below. By 2013, there first Stereolithography (SL) printers are on the market for as little as $10000 or even less. By 2016, the cheapest printers from China cost around $300. As of 2017, you also can get very cheap printers made in Europe.

The CubeX came out in 2013 and sponsors a bigger print area, optional dual/triple head, and improvements in quality. The CubeX can be considered a successor for the BFB 3000 (from the bought-up now dead british company that pioneered 3D printing with the Rapman). It looks as heavy and solid as the BFB :)

[http://www.felixprinters.com/ Felix] is the IMHO the first European company to offer a low cost printer that is easy to assemble, according to the website. Assembly of the current DYI model (Felix 3.x) seems to take about 5 to 12 hours depending on your DYI skills. Felix DYI printers also can be bought assembled. The Pro line is assembled and takes about 10 minutes to set up.
 
* We bought a Felix 1.0 in March 2012, a Felix 2.0 in October 2013 and a Felix Pro 1 in December 2015. - [[User:Daniel K. Schneider|Daniel K. Schneider]] 13 March 2012/25 october 2013
* Read: [[Felix 3D printer]], [[Felix 2.0 3D printer]] and [[Felix Pro 1 3D printer]] for some how-to information and for an informal experience report.
 
; [http://www.felixprinters.com/ Felix 2.0] (2013)
** Kit: 1000 Euros
** Fully assembled and tested: 1400 Euros
** Aluminum frame, assembled by screwing 6 hex bolts, Drylin-sliding bearings, Opto-sensor, NEMA 17 motor
** RAMPS 1.4 electronics
** 0.35mm diameter nozzle
** 1.75mm filament
** Build size: 235, 205, 200 mm
** Z accuracy: 0.05 mm
** Opensource Repetierhost control software.
** The printer is designed for PLA printing, however it also can print ABS if the print platform is adapted (various methods)
 
; Positive sides of the Felix 1.0 (after our own experience in 2012)
* Reliability (long over night print, 24h prints)
* Accuracy, probably as good as any other high-end printer.
* It can be '''easily carried around''' (crucial for some school settings). It doesn't weight much and has a handle on top. The geometry will remain stable, as opposed to "pure" RepRap designs that may need recalibration after transport.
* Good combination between closed source (the frame design, etc.) and opensource (arduino board, controller software)
 
; Negative for the Felix 1.0 (after our own experience in 2012/13)
* Typical filament printer problems that all of them have (e.g. clogging if the filament is bad or dirty, warping, large flat objects not sticking, overhangs)
* Calibration work is difficult if (and only if) you plan to get the optimal prints
 
; Positive sides of the Felix 2.0 (after a '''few hours''' and the three first prints on oct. 25 2013 !)
* Like the Felix 1.0 it worked out of the box. Setting it up took about 30 minutes (getting it out of the box, downloading a new version of the controller/slicer software). We skipped calibration, but just made sure that the print head would not touch the printbed.
* With respect to the Felix 1.0 (2011/2012), the 2.0 seems to print with better precision. However, we will have to create new SFACT problems for Lego printing. Standard settings (several) are fine, but as we always claim: There is no such thing as good universal standard settings that work with all types of objects ...
 
; Negative
* Probably due to transport, the platform was not totally level (about 0.2mm to high in the x/y=0 corner. Therefore we had to recalibrate (tighten the screw).
* After that, the hotend was a bit too close to the printbed (less than 0.1mm) and we had to adjust the Z homing sensors (turn the screw in the right direction ...)

In oct. 2011, this model seemed to be one of the easiest solution to start 3D printing, i.e. you can unpack and print and don't need to learn about calibration with tools like [[Skeinforge for RapMan|Skeinforge]]. On the downside (if I understand right) one only can print ABS in three settings (fine, normal and coarse). Also, the print area is small compared to a RapMan.

== Commercial entry-level SLA / DLP printers ==
 
Since 2012, SLA technology was available for hobby printing. Resin is exposed to ultra-violet light that will harden it. DLP, using standard computer screens, came soon after.
 
Printing is somewhat easier but requires a bit more post processing, some cleaning effort and the material (resin) is more expensive. As of Jan 2018, there exist more than two dozens SLA and DLP printers, e.g. read [https://all3dp.com/1/best-resin-dlp-sla-3d-printer-kit-stereolithography/#3d-systems-projet-1200 this].
 
Make sure to understand that you will have to clean up messy resin and to wash and cure the result.
* Use Nitril gloves (e.g. buy from an online general retailer) and protective glasses.
* You also should buy a proper "curing station" as opposed to use simple containers with solvents (usually Isopropyl alcohol, 90%+ (IPA))
* You should find an appropriate workspace and add maybe a stainless steel workbench, e.g. [http://www.webstaurantstore.com/regency-24-x-48-16-gauge-stainless-steel-equipment-stand-with-undershelf/600ES2448S.html like this one] mentioned by Autodesk. Resin may spill and damage your nice wooden office  furniture.
* Waste includes resin and solvents and should be handled appropriately. You can use a large plastic bottle for that and then dispose in an appropriate place.
 
While SLA/DLP printers allow to print much more precise objects, the post processing and cleaning up is not well liked by many users.
 
'''Outlook for 2020/21'''. One of the main advantages of resin printers is speed (in particular if you plan to print a series of small objects. As of 2019, some models like the [https://zortrax.com/blog/resin-3d-printing-faster-and-more-precise/ Zortrax Inkspire] claims to be 10 times faster than a "normal" model. In the meantime, 3D printing research promises printers that will 100 times as fast, e.g. [https://spectrum.ieee.org/tech-talk/computing/hardware/3d-printing-is-100-times-faster-with-a-powerpoint-projector This 3D Printing Technique Is 100 Times Faster Than Standard 3D Printers] (IEEE Spectrum, Jan 2019) and [https://www.nature.com/articles/d41586-018-07798-9 Forget everything you know about 3D printing — the ‘replicator’ is here] (Nature, Jan 2019).
 
Below we shall describe some SLA printers, see the next section for DLP.
 
=== 3D Systems ===
 
As of May 2018, the '''FabPro 100''' is the second (relatively) cheap SLA/UV printer from industry leading 3D Systems. It replaces the ''Projet 1200'' model. It claims to print fast. It has less build space than the Form 2 and we wonder in what respect this model could be a better buy. Maybe because 3D Systems did invent and patented SLA printing technology many years ago...
 
[https://www.3dsystems.com/3d-printers/fabpro-1000/specifications Specifications] include:
 
* Size and weight: 43 x 43 x 61.2 cm for 37.5 kgs
* €5,795 including a UV Curing Box (€4,295.00 without) delivered to France or Germany.
* Layer thickness: 30-50 micron
* Build size:  125 x 70 x 120 mm
* Vertical build speed: between 5.3 and 14mm depending on materials (FabPro Proto Gry is fastest)
* 1 year warranty (extra warranty can be purchased)
 
Materials:
* Resin seems to be proprietary (FabPro either black/tough, grey or JewlCast) and a bit expensive, i.e. €129.00 for 1l of FabPro Proto GRY.
 
If this machine works like the FormLab 2, then probably other materials could be used, in particular [https://makerjuice.com/ MarkerJuice] which cost less than half price.
* Wavelength is 405 nm
 
The no longer available Projet 1200 was a bit more expensive and had a smaller build volume
* $5000
* 42.9 x 149.9 x 26.9 mm build volume
* 30 microns min. layer height
 
=== Autodesk Ember ===
 
As of Jan 2018 [https://3dprint.com/170791/autodesk-discontinues-ember/ manufacturing of this is discontinued]. The design is open source and in principle someone else could have built it, but it did not seem to happen. Made by CAD software giant, this printer integrated with Autodesk Print Studio.
 
* x/y resolution: 50
* Layers: 10-100 microns
* Build volume 64 x 40 x 134 (which is very small)
* Around $7500 ?
 
Autodesk sold its own resin, but was compatible with number of others, e.g. from DWS, Formlabs, Asiga and MadeSolid.

1 litre Resin costs about 190 CHF. Flexible resin is around 250 and Dental up to 650. Prices are lower in the US. It is also possible to use cheaper resin, e.g. [https://makerjuice.com/ MakerJuice] which is less than half price ($44 in the USA)
 
As all these printers, handling a print and the Resin is a messy affair. This is why Formlabs offers extra post processing devices for cleaning and also stabilizing the print. The best option (Form Wash + Form Cure) costs an extra 2K (less in the USA).
 
=== UNIZ ===
 
Sells The Slash and (probably) in June 2018 a Slash+. These models seem to be comparatively cheap, have a fairly large build volume and are pretty fast. However, as of Feb 2018 there are no serious user reports and the documentation on their website is less than good (just pictures and specifications). Most online "reviews" are just copy/paste propaganda. If the printer works, it would a good alternative to Photocentric models who do get mixed reports for now (jan 2018).
 
'''The Slash'''
* LCD Stereolithography (similar to SLA technology)
* Build volume 192 × 120 × 200mm, which is large for its category
* Layer thickness 10 to 300 microns
* XY resolution 75
* Claims to print 1000 cc/hour, which is rather fast.
* 12 KG
* $2000 (USA), about 2320 Euros (incl. VAT) in France/Germany via RobotShop

== Commercial entry-level DLP printers ==
 
DLP printers start cheaper than SLS since projection technology (a LED screen) is cheaper, but there exist also expensive models.
 
=== Wanhao ===
 
[http://www.wanhao3dprinter.com/ Wanhao] produces a very cheap DLP model as of Jan 2018.
 
* The Duplicator 7 only costs $500 (see [https://www.usawanhao.com/wanhao-duplicator-7-v14-red- US Site]. From a Swiss distributor, count CHF 700. On Amazon US, $555 and EUR 482 on Amazon DE. Make sure to get the ''latest'' version.

* XY Resolution: 35 microns
* 12 kg
* 395-405nm UV Resin, i.e. compatible with most resins on the market. Their own resin is 75CHF/litre.
 
This printer seems to be particularly "messy" and early models suffered from small engineering mistakes. However, it does have a very good price. It also may be a good idea to buy a separate control unit (about $160).
 
=== Photocentric3D ===
 
[https://photocentric3d.com/ Photocentric offers] three models as of Aug 2017. They use DPP (Daylight Polymer Printing) which use much less energy than SLA. Also Resin (both standard and flexible) seems to be cheaper and comes in some variety (strength, flexibility, color). Some reviews complain that printing is not easy and cleaning difficult. However, a model can be cleaned with hot water, as opposed to alcohol-based solvents that must be used for UV resins. Requires a VAT-film that must be changed every 5 prints.

== Commercial entry-level SLS printers ==
 
Although SLS patents expired some years ago, it took time to see "powder"-based printers appear on the market. As of Sept 2017 there are several machines. Also take into account that you should buy extra machines for dealing with powder recycling and for blasting printed parts.

== Commercial desktop printers ==
 
These range from 20K to to several hundred K. See also above for some interesting SLA and SLS printers that have become fairly cheap.
; Technology
Commercial desktop printers use a variety of patented technology. Most are power-based, but there are also hight end filament and SLA printers.
 
; Cost
Roughly speaking, the cost of printing with commercial desktop printers is about CHF 500 / liter or kilo, i.e. around 0.5 CHF or 0.4 Euros per cm3 or grams. For example, a 4x2 standard Lego brick is about 2.5 grams and therefore should cost about a Euro. Price for solid objects like [http://www.thingiverse.com/thing:1216 this] depends on the filling and whether the printer can do non-solid fills.

Introduction

This article shortly introduces 3D printers and provides some advice on selecting a printer. The original article, created many years ago, listed many printers, but I stopped upgrading systematically around 2016. The old version is still around. There are no endorsements, since I only owned a RapMan (2010), a fabbster (given away), a Creality (2015, given away), four different Felix printers (1.0, 2.2, Pro2 and Tec4.1 (I still use the latter two), a Fokoos Odin-5 F-3 (2022, bought for 200 Euros on sale) and a Creality K1 Max. I also use Prusa mini and I3 printers in our fablab.

According to Wikipedia, retrieved 11 April 2023, 3D printing or additive manufacturing is the construction of a three-dimensional object from a CAD model or a digital 3D model.[1] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control,[2] with material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.

3D printing technology

The most popular 3D printing techniques are:

  • Fused deposition modeling (FDM), also called Fused Filament Fabrication (FFF). A typical example of the first available low cost kit that required a few days of assembly was the RapMan. As of 2023, entry level printers are cheap (around 300 Euros) and are assembled fairly quickly. Consumer-grade quality machines cost around 1000.
  • Stereolithography (SLA): “is a form of 3-D printing technology used for creating models, prototypes, patterns, and production parts in a layer by layer fashion using photopolymerization, a process by which light causes chains of molecules to link, forming polymers.[1] Those polymers then make up the body of a three-dimensional solid.” (Wikipedia, Aug. 2017). SLA machines use a laser to harden selected areas.
  • DLP (Digital Light Processing) works, like SLA, with resin. As opposed to a laser that will solidify very specific areas, a DLP printer projects an image onto the pool of resin which then hardens each layer, one at a time.
  • Selective laser sintering (SLS): “an additive manufacturing technique that uses a high power laser (for example, a carbon dioxide laser) to fuse small particles of plastic, metal (direct metal laser sintering), ceramic, or glass powders into a mass that has a desired 3-dimensional shape” (Wikipedia, retrieved 14 October 2011)
  • Syringue-based systems like the early Fab@Home can print Epoxy (composites), ceramics or food and these materials are pushed down with a piston.

Most hobby 3D printers use FDM, i.e. an extruder (i.e. a kind of gun) that heats up plastic filament which is then deposited layer by layer. They can print different sorts of Polymers. In the early years, the two following plastics were popular.

  • ABS (used for Legos and car parts) is solid, but warps when printed a room temperature. I.e. it is difficult to print objects that have a larger than 4cm footprint.
  • PLA (polylactic acid) is made of starch (i.e. plants). It doesn't warp, but it was not very solid and started deforming (melting) at relatively low temperature. As of 2023, more solid PLA filaments are available.

As of 2015 a much wider range of 3D printer filaments are available, including PET-G, PET, Nylon, TPU, TPEs, and various PLA-particle composites.

Comparison chart of 3D printing technology
Type FDM / FFF SLA SLS Piston
Material rolls of various types of plastic Liquid resin Various powder (only Nylon or similar for low end machines) Anything that can be pushed down (e.g. chocolate or Epoxy resins or clay)
Durability OK (depending on type of plastic) Low High depends on the material, very little for printed food :)
Precision 0.05 mm high good
Post-processing Easy (except when dealing with support materials) Treatment is required to improve solidity Blasting is required to remove bits of loose powder
Freedom of forms No.

Somewhat if soluble support is used in dual head printer.

limited yes very limited
Heat resistance Depends on the plastic. E.g., popular PLA is starts weakening at 60 and melting at 160. PETG, and other popular plastic has a higher melting temperature. Some plastics like nylon are difficult to print but much more resistant limited good
Unit cost very low (starting at 150, a good model is about 1000) low high medium
Material cost very low to low (15-100 Euros/kg) 30-250 Euros / litre 100 - 1000 Euros / kg.

The opposite of additive manufacturing is subtractive manufacturing that takes away material from an initial form. These alternative technologies include:

  • Laser cutting, a fairly simple to use technique for creating "flat" 3D objects by cutting "sheets" like wood or plexiglass. One can create designs that involve sticking or gluing components together.
  • Milling, a process where parts of an object (e.g. a cube) are removed by drilling. For example, parts of car motors are produced like this. Milling is a fairly dangerous process, however hobbyist models that carve out from plastic or wood are safe to use in a classroom for example.

Filement printer features you should you look for

Must have features:

  • A strong extruder including a good filament intake system (you should be able to walk away from the printer and be sure that plastic is always extruded, even after 20 hours or printing). Newcomers don't often get the fact, that even a fairly small piece takes many hours to print !
  • A good board and firmware (as above, there should be no mistakes, i.e. a print head that stops moving at some point)
  • A heated platform up to 80 degrees at least
  • Ability to print 0.1mm layers accurately

Nice to have features:

  • Support for different nozzle sizes up to 0.8mm (easy changing plus useful information on supported nozzles and how to change them)
  • Support for multiple types of plastic, in particular PLA and PET-G, but also some stronger plastics like ABS or Nylon (for some, this is a must-have feature). Some people also want to print with flexible polymers, i.e. TPU or TPE. That requires a direct extruder where the motor sits on top of the nozzle (i.e. so-called Bowden extruders are not very suitable for TPU and not suitable for TPE)
  • Extrusion and printhead movement speeds as slow and as fast as possible. Typically the first layer should be printed at 10-15mm/s but prototype quality should be printable at 150mm/s.
  • A heated chamber (or at least a closed box) for printing plastics that warp, e.g. ABS.
  • Accuracy (both detail and movement) down to 0.1mm resolution if possible
  • Two print heads (for printer either two color models or designs that need support. In the latter case, there exit soluble plastics.
  • Included easy-to use printer control software
  • Support for a good machine code generation software (i.e. a slicer). Most printers work with open source slicers but the vendor should nevertheless provide some good standard settings.
  • Support for standard RepRap g-code (in order to avoid slicer software lock-in)
  • Control hardware/software that allows to pause/resume a print and to manually extract filament.
  • As many standard hardware parts as possible (this will allow for quick replacement) and allow you cope if the company goes out of business. This includes the control board.
  • Use of open source software for controlling the printer. Except for very few exceptions, opensource solutions like Repetier Host are simply better since you can still use your printer after the company and its software go out of business
  • Automated bed leveling or model correction. Adjusting the bed (1-2 sheets of paper distance from printhead to bed in every position) is something that beginners have trouble with.
  • A wide printing area (as wide as the objects you plan to print). 25x25x25 is OK as of 2023.

Comparisons

Comparing 3D printers is very very difficult for several reasons:

  • Some do better than others with respect to different sorts of objects. Do the benchmark pieces represent what you would like to print ?
  • Calibration is essential. Only a real expert can get the most out of a machine.
  • How do you weight various factors ? (Reliability, smoothness/accuracy, min. layer size, speed or less obvious stuff like does the first layer stick, warping, dealing with overhangs, stringing)
  • How do you account for the interaction between slicing software and printers, and between slicing parameters and printers ?

On of the first serious comparisons was done by Make Mag in nov 2012. One of my printers (the Felixprinter 1.0) came out ok. Nevertheless the author complained about assembly that was more difficult than expected and glitches with some delivered parts (like calibration of the stepper motors) and he is right to do that. However, why compare a non-assembled printer with assembled ones. I bought mine assembled (400 Euros extra) and it worked out of the box! In addition, the testers used default settings of the slicer software. Had they selected a different profile they would have obtained widely different results. I was able to print a test design that failed without problems. The Make Mag test was serious, but far from perfect. - Daniel K. Schneider 17:53, 22 November 2012 (CET)

Do not trust marketing hype. In any case, filament printers do have inherent flaws that no design can solve. Only trust reputable online sites (most receive something in exchange for rewiewing). Also, understand that some cheap printers start degrading after a few weeks and that others have poor quality assurance (i.e. some machines work fine but others need to repaired when you open the box).

Fast 2023 FDM machines

I am looking into these models right now and may buy one. By the end of 2022 very fast "coreXY" FDM printers did appear on the market or were announce for Q2 or Q3 of 2023. An other options are IDEX printers where two extruders can work at the same time on copied or mirrored same objects. Since Summer 2023, fast "bed slingers" like the cheap Kobra 2 from Anycubic did appear.

Since I hate waiting a full day for a moderately large bag of LEGO or DUPLO compatible bricks I am interesting in getting one of these model and would print with a 0.6mm nozzle or larger.

Some of these printers may require minor modifications, e.g. better PEI print plates (e.g. read this for the Bambu) or better nozzles. All probably require verification and some tuning after the transport.

If you looking for a popular cheap machine, you could check out:

  • Creality Ender-3 S (the Pro version is more expensive, but worth it, the Plus version has more build space)
  • Artillery Sidewinder X2
  • Anycubic Kobra

You can find these in many online shops. Prices can vary greatly at times. If you are low on budget, watch out for 50% sales, e.g. around 150 to 200 Euros.

If you are looking for a reliable, a bit more costly machine (out of the Box and staying), check out:

  • Prusa mini or Prusa i3 MK3

Avoid expensive commercial brands that offer consumer machines with lesser functionality for higher prices, e.g. Makerbot Replicator.

History of consumer-grade 3D printers

Below, some consumer-grade 3D printers that made early history after 2005 where Adrian Bowyer launched the RepRap Project. Most links will be broken, since pages have been taken down or the companies went out of business.

Reprap 3D FDM printers

Prusa Mendel

RepRap, a British project, is short for Replicating Rapid-prototyper. They all can be assembled from parts bought in various places. In 2018, there were several different Reprap Designs. The classic ones plus some other earlier designs are the following:

All RepRap printers can built with spare parts available from many places. However, this requires good "bricolage" skills. For those who don't have these, there exist many commercial kits that are relatively easy to assemble and also fully assembled kits (see below).

The CandyFab 6000 sugar-based 3D printer

Candyfab printers

Candyfab was one of coolest projects in the beginning of DYI 3D printing. It did sugar sintering.

Rapman 3.1. schema - Source: Bits from Bytes

Bits from Bytes printers

Bits from Bytes did produce and sell Reprap derivatives, in particular the RapMan v3.11 (£750 / CHF 1270) we acquired in January 2010. It was assembled by end of Feb 2010 Read the RapMan article. The company is now dead, i.e. it was absorbed by 3D systems.

  • Print area: 27 x 20.5 x 21 cm, not heated platform
  • 3mm nozzle
  • Resolution: x&y axis = 0.2mm, z axis = 0.7mm (roughly)
  • Materials: ABS (warping for bottom surfaces larger than 4-5cm), "Hard", original translucid PLA (very different from "modern" processed PLA).

The Rapman was one of the first commercial kits for the RepRap v1 and it's probably one of the most beautiful designs. Assembly was rather difficult, but very well documented. All you needed was good reading skills. It did work, but did need what we could call "RepRap printing skills". Some design elements could be improved, in particular: filament intake (extruder), portability (after transport the structure may need adjustment), heated platform.

Fab@Home version 2

Fab@Home 3D printers

Fab@Home, is marketed as "personal fabricator". As opposed to RepRap designs, Fab@Home used a syringe system and could print a large variety of materials, including silicone, cement, stainless steel, cake frosting, and cheese. Hardware designs and software on their website were open source. This printer also included a dual syringe tool for printing two materials simultaneously.

Cupcake/Thing-O-Matic 3D Printer

Makerbot printers

MakerBot Industries sold other RepRap-inspired designs. Like other Reprap derivaties, their 3D printers included a plastruder and an Arduino-compatible microcontroller and worked with several kinds of plastic, e.g. ABS and HDPE (milk-jug like). The founder of this company was also involved in the RepRap research project.

  • A free design called CupCake CNC and and its current (2011) Ultimate. Makerbot will sell the parts. I don't know if there is any difference in design with respect to the Thin-O-Matic kit.
  • MakerBot Thing-O-Matic® Kit (formerly called Cupcake?)
    • Between $1225 and $1300 for the kit and à2500 fully assembled
    • 3mm extruder
    • 9.6 x 10.8cm print area

Later, this company developed closed sourced systems that became popular with institutional buyers. The company still sells expensive rather high-end machines.

MakerGear Prusa 3D Printer

Makergear

Makergear sold two kits as of oct. 2011. One is rather destinated to people who want to play with the Mendel Prusa design and maybe do creative modifications. The other, i.e. the Mosaic was more of an end-user product.

  • Prusa 3D printer kit
    • $825 for a complete kit
    • 8 x 8" Heated Build Surface PCB
    • Either 1.75mm or 3mm hot end (allowing to print either more precisely or faster). Most current printers feature a 3mm nozzle.
    • supports both ABS and PLA
  • Mosaic 3D Printer kit
    • $999
    • (Probably) fairly easy to assemble

Printrbot

Probably was one of the most popular 3D printers as of summer/fall 2012. S

  • printrbot.com
  • Open Hardware Design
  • z axis: printhead moves up (not the platform)
  • Heated platform that moves in the y axis (or x axis depending on how you look at it)
  • Cheap, i.e. between $400 (smallest, print bed not heated) and $700 (largest)
  • The large Printrbot PLUS has a 8x8in heated bed
  • Claimed to be fairly easy and quickly to assemble

Shaper Cube

Ultimaker

As of Oct. 2011, the Dutch Ultimaker was the favorite open source design kit. It was (comparatively) fast, could print big and was easy to assemble compared to a RapMan for example. Ultimaker focused on speedy PLA printing and contributed to make this somewhat ecological filament the most popular.

Hardware:

  • The Ultimaker 1 Kit costs EUR 1200.
    • Reprap design
    • It can print 21x21x22 cm volumes
    • USB connectivity, drivers for Win/Mac and Linux
    • 0.4mm nozzle The theoretical resolution: 0.0125 mm for the X and Y axis and better for the Z-axis. Don't know what the practical one would be.
    • User-friendly feed mechanism
    • No heated bed (?)
  • Ultimaker 2 became a very popular machine in Fablabs, because of its good design, reliability and precision.

Web services for 3D printing

There several companies who fabricate 3D objects from models created by the public. Typically, online 3D printing services also include a store where users can both upload and sell designs. Some sites also offer other manufacturing and commercial services and most also provide free resources for learning how to create things

Software and formats

Roughly speaking, the production pipeline looks like this:

  1. Model something or find a model
  2. (Merge/adapt models)
  3. Translate to a printable model, e.g. STL, AMF, OBJ
  4. Translate the printable model to machine code, e.g. g-code
  5. Print

File formats

The most popular file format was and still is the .STL file format: “An STL (“Stereolithography”) file is a triangular representation of a 3-dimensional surface geometry. The surface is tessellated or broken down logically into a series of small triangles (facets). Each facet is described by a perpendicular direction and three points representing the vertices (corners) of the triangle. These data are used by a slicing algorithm to determine the cross sections of the 3-dimensional shape to be built by the fabber” (The StL Format, retrieved 17:25, 24 June 2009 (UTC)). STL files can be created with most CAD programs. Alphaprototypes provides instructions for several popular CAD applications. More recent formats like 3MF are more versatile and can for example include color information.

3D Printing software

We distinguish between three kinds of "printing software"

  • Preparation software will take a 3D model, allow you to make some adjustments (like repairing) holes, positioning and rotation and then output a clean printable format, in particular .STL files. The most popular software in that category in the early days was Netfabb Studio (now absorbed by Autodesk). As of 2023, most slicers include some automatic basic repair facilities.
  • Slicer software will take as input an .STL model (or similar) and then produce machine code according to various parameters that you can set.
  • Control software, can send print files to a printer and control the printer otherwise (e.g. manually move the print head, change temperature, etc.)

Some software can do all of these.
