Laser cutters allow to cut most sorts of material precisely and quickly.
Low-cost Laser cutters typically used in Fablabs can cut and engrave. They can use materials materials such as wood, plexiglas or cardboard and cut out various shapes and sizes from them.
Low-end laser cutters allow to cut materials like wood, leather, plexi glass (PMMA) and also to engrave.
- Laser cutting category
- For the moment (12/2016), technical information about laser cutting is available in Trotec Speedy 100R
Laser cutters (unlike 3D printers) are fairly dangerous toys.
- Toxic fumes can make you sick (and worse)
- Laser beams (which are invisible) can make you blind. Broken laser tubes can be extremely dangerous.
- You need a machine with safeguards and that includes the power system.
- An air filtering system. In a city environment you cannot just expel the fumes out of the window.
- If you work with an "unsafe" machine, you will have to buy special glasses that are tuned to the frequency of your laster (about 100 Euros). Not needed for a safer high-end model
- Make sure that the material used for cutting/engraving is not extra toxic. E.g. strictly avoid anything that includes chlorine, e.g. PVC, ABS. Avoid inhaling fumes from composite wood, such as MDF.
There are regulations for laser beams in western countries and your machine should comply. E.g. see the German Unfallverhütungsvorschrift. I don't know whether private persons can ignore such regulations, but schools definitely cannot.
- Laser tubes must be replaced after 1000 - 10000 hours (depending on the make and model)
- Optics (mirror and lens) must be cleaned (e.g. use Isopropanol)
- If you use watercooling: Water must be clean and remain cool
- If you use a air filtering system, change the filer and active carbon
2 Opensource kits / do it yourself
- Co-financed through a Kickstarter project: Lasersaur: Open Source Laser Cutter (July 2010)
Quote: “The Lasersaur is an open source laser cutter. We designed it to fill the need of makers, artist and scientist who wanted a safe and highly-capable machine. Unlike others it comes fully loaded with knowledge to run, maintain, and modify.” (Lasersaur, 6/2014).
- Work in progress as of June 2014
- Is not a laser cutter but a board + software. It can be be used to onvert existing machine with a better (open source) driving board or for DYI projects.

3 List of low power commercial laser cutters
This is a just a quick list made be someone who has no expertise. It also is probably outdated. As of 2016, expect prices to come down a lot in the near future, e.g. on Aliexpress one now can buy systems for a 1000 Euros. There are systems in the range of 2000-3000 that look like systems sold in Europe for over 20K. The cheapest engraver (a cute wooden DVI model) is $135.
European and American online retailers (e.g. Amazon) also start selling cheap lasers. E.g. on Amazon.fr they start at 2000 Euros. Search for "machine de découpe laser" for example. In German, search for "Laserschnitt", "Laser Schneidemachine", "Laser Graviermaschine". Buying from a local vendor will probably add 50% or 100% to the price tag, but (1) there won't be custom's problems and (2) if something goes wrong, negotiations could be easier.
When comparing prices consider the following (thanx to Wie ich mich für einen Laser entschieden habe.... by Matthias Melcher)
- Laser tubes must be replaced once in a while (cheap ones cost 500 Euros, good ones 3000 Euros and more). Cheap ones last a few hundred hours, excellent ones (e.g. Synrad) over 20'000 hours (that's many years). In other words, price differences are partly explained by the quality of the laser. The same is true for other parts (mirros, filters, etc.)
- Cutting/engraving most materials produce dangerous fumes, therefore you also must buy a system to manage the exhausts, i.e. either pump it outside or into a box with a filter. Some materials contain Chlorine (e.g. PVC) and that produces very corrosive fumes. You should not cut these, even with a good exhaust system since the acid will damage your machine.
- Most activities need cooling (air or water)
- The laser beam is invisible (but you can add some red dot)
- Cutting depth is limited, you can't cut deeper even with several passages because the laser is "conical".
- Lasers can burn (therefore don't leave it alone, and keep a fire extinguisher ready)
- A laser machine needs space, e.g. count exhaust system, cooler, etc.
- For many types of use you need extra materials, a cutting table with holes (honeycombed), a cooler (water pump), etc.
- Laser quality is fairly different, laser power is a relative measure of engraving/cutting strength.
- Cost / hour could be 20 Euros
In the hobby range, there are at least two types of lasers:
- C02 / glass. Good for leather, paper, acrylic (plexi glass) and plywood,
- yag and fiber (good for metal)
- Good software and support for various useful formats (such as SVG) can be mission critical. Software works with certain boards and vice-versa.
- There has been criticism of the MoshDraw software that is popular with many low cost Chinese brands.
Quality / origin: It seems that there are huge price and quality differences in the area of low cost / low power desk top laser cutters. E.g. laser cutters directly imported from China may cost half of Chinese models assembled in Europe, and the latter cost half of high-end American Models. E.g. seemingly similar machines can cost 4 times as much (or more):
- Direct imports for China: There are many models, e.g. BaiSheng, RedSail. Some of these can be adapted and certified by local companies.
- Western made/adapted from cheaper parts: Arketype, MLLog, FullSpectrum. (Often?), these models also provide their own software.
- Expensive parts, US or European made: Epilog, Trotec

4 Air filters
Also called "air extraction system"
If you cannot expel all fumes to the outside safely (think of other people in the same building), then you also need an air filter. These do not come cheap in Europe. However, chinese (cheap) models start at 1000, e.g. from Waterun, e.g. the F3000D model. I have no idea how well these work and what their consumption of filters are.
5 Online laser cutting services
Instead of buying a laser, you could also use an online service or maybe a local shop

- Experiences with cheap laser cuttes
- Using makes and models
- Software tools
- instructables.com includes quite a few laser cutting examples and tips. E.g. search for Laser cutter
