Reprap mendel 3d printer

Mendel - RepRap

Mendel Documentation

Main page | Mendel Buyer's Guide | Mendel Build Manual | Mendel User Manual | Mendel improvements

The machine on the right is the RepRap printer, which we call "Mendel" after the father of genetics. It's the second, improved version of RepRap: small enough to fit on your desk, but with a print volume large enough for you to make big things (see specifications below). The machine is made up of bits bought in from local suppliers or online, and parts which it can make for itself - all the translucent structural components you can see.

In the picture, behind the machine, you can see the RepRap software which you can use to print your thing. We give this, and the designs for the machine away, free - it's all open source (GPL 2). Though you do have to buy in some standard components from... well, whoever you want... which cost about €400. The idea of getting all the materials and building a machine yourself may seem daunting, but this area of the wiki is dedicated to making the whole process as easy as possible.

Click a "How To ...." link above for building and using tips and more....

There are a number of instructional videos distributed through the Mendel documentation. These are also all gathered together in one place here.

You can see examples of people's Mendels, and where they got their parts at Mendel Source Logs.

Mendel vs. Darwin

Mendel is the second RepRap machine. Mendel supersedes the first version, which we call Darwin. RepRap Version I "Darwin" instructions

Ed Sells, a student of Dr. Adrian Bowyer, designed and built the first Mendel printer, sometimes called a "Sells Mendel" to distinguish the original design from later tweaks. It has the following key improvements over Darwin:

Bigger print area, smaller machine footprint
Improved constraint on the z-axis to eliminate jamming
Better axis efficiency
Simpler assembly
Capacity for tool changing (to follow very shortly)
Lighter and more portable

This video illustrates these improvements:

RepRapPro Mendel 3 fitted with Duet electronics. These pages are the complete instructions for building, commissioning and using the RepRapPro Ltd version of RepRap Mendel 3. Like all RepRap machines, RepRapPro Mendel 3 is fully open-source. It is licenced under the GPL. All the design files and software are available from the RepRapPro Ltd Github repository.

These instructions document the assembly of a single material/colour “Mono” Mendel. The extra Tricolour instructions follow the Mono instructions.

It is recommended that Tricolour machines are initially assembled as Mono Mendels, before being extended to Tricolour machines after commissioning, and you have gained some experience using the Mono. You are building a complex machine – the skills required and the rate at which you learn mean that troubleshooting when you have built it all at once is much more challenging.

For the most part, the construction of the Tricolour is the same as for the Mono. At various points there are small tasks that you need to do for the Tricolour. These sections are highlighted in green on the relevant pages.

Give yourself plenty of space and ensure your work area is clean. Dust and dirt are a 3D printer’s worst enemy. All printed parts have been printed on various RepRap machines from suppliers within the RepRap community. Despite the fact that these machines are highly tuned RepRap 3D printers, some holes and features may need a little fettling to get the best performance from the RepRapPro Mendel 3. This is especially true for the Igus bushings used for the Z axis. There is a video how-to on fettling 3D printed parts here on Vimeo.

Before you start the build, please ensure you have all the components as listed on the packing list included in the kit. If anything is missing, please contact us via email:

We understand that people may want to change aspects of the machine’s design, and in fact we encourage this as it is one of the benefits of open source development. Before changing anything, please be aware that the RepRapPro Mendel has been designed to maximise the build volume relative to the the machine’s footprint, and as such many of its components fit closely to others. So consider your changes carefully before you try to implement them. And when you find improvements, please tell us so that we can include them in future kits, and so that existing owners can upgrade their own machines.

BEFORE YOU ATTEMPT TO ASSEMBLE ANY PART OF THE REPRAPPRO MENDEL 3D PRINTER, PLEASE READ THESE BUILD INSTRUCTIONS FULLY AND ENSURE YOU UNDERSTAND THEM. Although all parts are covered by warranty, this will be invalidated by your not following these build instructions.

The RepRapPro Mendel is a robust RepRap machine once assembled; however it does require a certain amount of care during assembly. If in doubt, force is usually not the answer! There are many ways to get support and advice, see the Get Support section below.

If you have bought the hardware-only version of the Mendel 3 kit, you will want to print the parts. You may also want to print spare parts for your printer. The list below shows the part number, part name, quantity and location of the parts. Most parts are available as STL or SolidWorks files, in the Mendel 3 github repository. Some parts common to all our machines are in the Library github repository. The extruder drive is in the Extruder drive github repository.

You can download all three github repositories, or download the parts individually; the ‘Location’ in the link below links to the stl page. This will also help you identify the parts. If you download the parts individually, make sure you download the ‘RAW’ version of the file; if you right-click on a link and download, you will end up with a file with the right name (with .stl on the end), but it will actually be an html document!

The

reprap takes the form of a free desktop 3d printer capable of printing plastic objects.

with many reprap parts made of plastic and reprap prints those parts

reprap self- repeats by making a self-kit a kit that anyone can assemble in a moment of time and materials.

this also means that - if you have a reprap - you can print a lot of useful stuff, and you can print another reprap for a friend. ..
