'''RapMan''' was one of the first commercial kits of the [http://reprap.org/ RepRap] 3D printer sold from 2009. '''RepRap''' is short for ''Replicating Rapid-prototyper'' since it was developed in a research project on self-replicating machines. TECFA bought its kit in november 2009 and we assembled it in the end of January 2010 ([[file:Invoice490DanielSchneider.pdf|thumb|PDF]]) As of 2019, it is displayed as museum piece in our location at Uni Pignon, Geneva.

== Assembling RapMan V3.1 ==
Assembly of V3.1 RapMan takes at least three full days. It can be done by any person who has good reading skills, patience and some "gift" for assembly. Bits from Bytes did produce a mostly very good set of documentation.
It is very important to understand what you are going to build. E.g. it's a good idea to look at a video like this[http://awards.becta.org.uk/display.cfm?resid=41885 film made for BECTA].
You also should understand more or less the following picture:

'''RapMan''' is a commercial kit of the [http://reprap.org/ RepRap] 3D printer. “RepRap is short for ''Replicating Rapid-prototyper'' since it was developed in a research project on self-replicating machines.

To model, there are several options:
* Create a mashup (take several objects and combine them)
* Learn how to use a multi-purpose [[3D modeling]] software
* Use some special purpose easy-to-use modeling software
* Learn how to use [[Computer-aided design and manufacturing]] software
* Scan a real object, e.g. with the low cost [[David Laserscanner]]


This article has two functions:
''' (2) Combining meshes'''
* It's a '''meta manual''' for '''Rapman version 3.1''': We will try to explain how RapMan works in order to help the reader understanding stages of assembly and we will point out to the most important manuals and other information sources you should read
* We will add some missing points and report some difficulties.


== Parts, manuals and workspace ==
Meshes (different objects) may be combined / merged. You can do this with the free Netfabb Studio and Meshlab programs. Creation of simple mashups with Netfabb and Meshlab is explained in the [[Meshlab for RapMan tutorial]] article.


When we ordered a Reprap it came in a fairly small plastic-wrapped cardboard box. In addition, we got some boxes with polymer filaments (6 ABS rolls and some others ...). To the left is a picture
An easier solution is to acquire the [http://www.netfabb.com/ Netfabb Professional]. It can export several objects (originally from *.STL files and other sources) as a single .STL file.
[[image:rapman-delivered.jpg|thumb|left|200px|Boxes from RapMan delivered on Jan 2010]].


It's easier to reserve a lot of space for assembly. At TECFA, we used our seminar room and took about 2 x 6 meters :)
''' (3) Create and fix the .STL '''


=== Overview of the manuals ===
In most cases, your 3D general purpose modeling or CAD program can't directly produce g-code. You first must export the
model to .STL (or another format like *.PlY).


All manuals are available at [http://bitsfrombytes.com/ Bits from Bytes]. At the time of writing they could be found in the [http://www.bitsfrombytes.com/index.php?option=com_content&view=article&id=80&Itemid=100009 downloads] section. The [ build info] section includes outdated version. So, in any case, always make sure that you get the manuals for the version you ordered, e.g. RapMan 3.1. Here is a list of the manuals:
You then may need to fix your .STL model, i.e. first make sure it has the right size and the right position. But there may be more tricky issues, like repairing "holes" (use [http://www.netfabb.com/ Netfabb] for this)
* Build Manual - Printed: This manual explains how to assemble the so-called '''cartesian robot'''. This refers to the printer (including the motors and the belts that will move the extruder in the X/Y axis and the plate up/down (Z-axis). In other words, it's all that's mechanical, except the extruder.
* 3D Build Manual part 1: As above but include 3D models that you can view in PDF. Click on a "picture" to enter 3D mode. Make sure to install the lastet PDF version and to use a PC with a decent graphics card. Also, explore the Acrobat menu to the left. You can add-remove parts for better visibility.
* 3D Build Manual Part 2: As above, part 2. Also includes writing of the motors and the controller.
* Animated Build Manual: As above, but includes animations. We didn't use this manuals
* Build Manual Videos: This manual includes three videos that show how to build some of the more difficult parts.
* Extruder Manual: Explains how to assemble the extruder, i.e. the print head that will be moved around in X/Y directions by the "cartesian robot". It will pull in the plastic filament and feed it into the so-called attached '''hot end''' which you somewhere during the assembly process. Finally it also explains how to wire the extruder to the controller.
* Hot End Manual: Explains how to assemble the hot end. The hot end will heat the plastic. It's a bit tricky to assemble since you have to wrap the heating wire around, attache a temperature probe and wrap fire cement around.
* Operations Manual: Explains how to use the printer. In particular calibrate the print head, update the firmware and use the controller interface.


'''Notice''': In some case, the newer version did not have enough information to understand the process. E.g. we looked at some 3.0 version manuals where procedures are explained in more detail. '''However''', this information needed to be adapted, '''because some parts are not the same''' and generally speaking 3.1 is '''easier''', in particular assemblying the hot end !
The coordinate system of the RapMan puts the origin in the middle. To manipulate size and coordinates, there are some options:


=== Tools ===
* Use skeinforge: turn on multiply plugin in skeinforge, setting the matrix to 1x1 or another value
* Use Netfabb for more simple resizing and moving operations (that's what I use)
 
''' (4) Create [[G-code]] '''
 
Then produce the [[g-code]], e.g. with [[Skeinforge for RapMan|Skeinforge]] or with Netfabb basic.
 
=== Typical tool chain scenarios ===


Then you will have to buy tools. All except two can be easily found in a do-it-yourself store:

''' Reusing ready to print objects '''


== The assembly procedure ==
* Get a model from [http://www.thingiverse.com/ Thingyverse] (or another repository for 3D printable objects. Make sure to select one that has a "rapman" or "reprap" tag on it. A fun thing to do would be printing all the [http://www.thingiverse.com/thing:1983 Beco] blocks. Since they are all similar, you can vary printing parameters and learn about calibration of small simple object printing without having to look at the same object...
* You likely will find almost directly usable .STL files, but you may have to align them to x/y/z = 0. You also may find various source formats produced with various 3D modelers.
* Import to skeinforge or netfabb and generate g-code. In both cases, make sure that it sits in the right position.
* Then verify the g-code manually


=== Practice run ===
''' Build an easy model with an easy 3D modeler '''

* Always extrude 1/2 m of filament before printing. Also play with temperatures. E.g. 247 for ABS may be too much.
 
* Make sure that your .STL files have the x/y/z values set right. Minimal z value = 0. The middle of the object should roughly sit on x=0 and y=0. Get the free [http://www.netfabb.com/ Netfabb Studio] to achieve this. Also use this software to clean up bad .STL files.

Introduction

Rapman V 3.1. assembled at TECFA (picture taken just after assembly in January 2010)

RapMan was one of the first commercial kits of the RepRap 3D printer sold from 2009. RepRap is short for Replicating Rapid-prototyper since it was developed in a research project on self-replicating machines. TECFA bought its kit in november 2009 and we assembled it in the end of January 2010 (File:Invoice490DanielSchneider.pdf) As of 2019, it is displayed as museum piece in our location at Uni Pignon, Geneva.

Printing instructions are written in a language called G-code. A user will copy a g-code file to an SD card. This card is then inserted into a slot of the RapMan board for printing.

Assembling RapMan V3.1

Assembly of V3.1 RapMan takes at least three full days. It can be done by any person who has good reading skills, patience and some "gift" for assembly. Bits from Bytes did produce a mostly very good set of documentation.

It is very important to understand what you are going to build. E.g. it's a good idea to look at a video like thisfilm made for BECTA.

Process overview

There are three situations:

  • You just want to print existing models with a minimum of hassle
  • You may take existing models and adapt (or even merge parts)
  • You'd like to model printable 3D objects

(1) Modeling:

To model, there are several options:

(2) Combining meshes

Meshes (different objects) may be combined / merged. You can do this with the free Netfabb Studio and Meshlab programs. Creation of simple mashups with Netfabb and Meshlab is explained in the Meshlab for RapMan tutorial article.

An easier solution is to acquire the Netfabb Professional. It can export several objects (originally from *.STL files and other sources) as a single .STL file.

(3) Create and fix the .STL

In most cases, your 3D general purpose modeling or CAD program can't directly produce g-code. You first must export the model to .STL (or another format like *.PlY).

You then may need to fix your .STL model, i.e. first make sure it has the right size and the right position. But there may be more tricky issues, like repairing "holes" (use Netfabb for this)
