RepRapPro Tricolour Mendel
by RepRapPro, published
Here are all the 3D printed parts for the RepRapPro Ltd version of Mendel. This is a three-head machine, so it will do colour and multi-material printing. But if you only want one colour, just leave off two extruders and drives, and the slave controller electronics...

The master version of all the files for this is on Github here:
See that link for the latest version of all the files.
The .ZIP file contains the trays of printed parts you need to make a complete RepRapPro Tricolour Mendel except the extruder. For the extruder, see Github here:
The two production trays are included for ease of printing if you have a 3D printer with a build area of 200x200mm or greater. Or the individual STL files are also included; it should be possible to print all these on virtually any 3D printer.
RepRapPro Tricolour has been specifically designed to work with three colours or three different plastics at the same time. Also we've made a lot of changes in order to make it ease to use :
-The volume and number of printed parts have been reduced so it's easier to assemble and more reliable.
-We have enhanced the widely-used Marlin firmware to allow the addition of a slave controller board to drive the extra extruders. And we are using the Arduino-compatible Melzi electronics for both the master and slave controllers.
-We've released our own RepRapPro Slicing software(Beta) in order to print multimaterial parts. Whilst Slic3r also supports multiple colours, we are currently working on modifications in order maximise multicolour print quality.
-The extruders are now specifically designed to come apart when the plastic filament being driven is in the drive the filament itself holds the drive together securely. But with no filament in it, the drive dismantles without tools for easy cleaning and servicing.
-The build volume has been increased when using multiple extruders to 210x190x140mm.
-The x-carriage is capable of supporting up to four extruders with future electronics, but three with the current generation. However this fourth extruder mount also allows for other tools and accessories, such as an extruder fan mount for higher quality PLA prints at fine layer heights.
-The Y bed is now mounted on stiffer springs and cap screws to ensure a more rigid bed and higher quality prints.
-The Y motor mount has now been redesigned to be made from laser cut MDF or to be printed and results in a much quieter machine.
- Belt tensioners are now easy to access for improved maintenance
