Tricolour Mendel


This listing is no longer active – for the most up-to-date Mendel printers, please follow this link –

This is a RepRap Mendel Printer designed to work with three colours or three different plastics at the same time.

In addition to the opportunities this gives you to put lettering on 3D prints and to produce muti-coloured objects, we are researching many functional materials for future release that you will be able to build with. These will include electrically-conducting plastics, magnetic plastics and soluble support materials.

Product Description

This listing is no longer active – for the most up-to-date Mendel printers, please follow this link –

The RepRapPro Tricolour Mendel 3D printer is a Replicating Rapid-prototyping machine, or RepRap for short. It is an open-source derivative of the equally open-source RepRap Project which was started at Bath University, UK, in 2004. The machine uses a process known a Fused Filament Fabrication, which it employs to build 3-dimensional objects in a range of plastics and in a variety of colours.  This process enables the user to create almost any shape which can be modelled on a computer, including some which could not be produced by traditional manufacturing techniques at all. Many examples of the objects people have made with Mendel and similar machines can be found can be found in the online repositories listed here.

The RepRapPro Tricolour Mendel is one of the most versatile 3D printers available in terms of the number of materials it can work with at once. Its primary design goals were to offer a printer which is easy to expand in functionality, which is low-cost, which is fast to replicate, and which is fast to assemble and to commission. Since its inception at the start of 2012, the RepRapPro Mendel Range has undergone brisk development and heavy testing.


RepRapPro Tricolour Mendel specifications

The specifications of the Complete RepRapPro Tricolour Mendel Kit and the RepRapPro Tricolour Mendel Hardware Set are identical.

   – Build volume: 210x190x140mm
   – Overall size: 500x460x410mm
   – Printing materials: ABS, PLA, 1.75mm diameter thermoplastic.
   – Build surface: PCB-heated bed to reduce complexity of assembly and to ensure parts do not warp.
   – Computer interface: USB
   – Standard nozzle size – 0.5mm
   – X-carriage: Three Z-adjustable deposition heads.
   – Accuracy: 0.1mm
   – Resolution: 0.0125mm
   – Building speed: 1,800 mm/min
   – Moving speed: 12,000 mm/min
   – Deposition rate: 33 cm3 / hr
   – Motion: Linear ball bearings on X and Y axes, Igus low friction bushings on Z axis.
   – Pre-soldered electronics with built-in microSD card slot for standalone printing.
(The resolution is how fine a step the motors can make. The accuracy is how accurately the machine can position things. So the  resolution is finer than the accuracy because the accuracy is influenced by other factors, for example how well the timing belt is manufactured.)


What’s in the Complete Kit and in the Hardware Set?

The Complete RepRapPro Tricolour Mendel Kit includes all components required to get you printing.  The RepRapPro Tricolour Mendel Hardware Set has everything in the Complete Kit except the 3D-printed parts of the Tricolour Mendel machine.

To 3D-print a full set of Tricolour Mendel parts to go with the RepRapPro Tricolour Mendel Hardware Set the files are in ourGithub repository.

Software to run the machine is also provided with both, including the firmware for the electronics.

Contents of the Complete RepRapPro Tricolour Mendel Kit and the RepRapPro Tricolour Mendel Hardware Set both include:

   – All hardware (threaded and smooth rods, screws, nuts, washers, belts, bearings etc)
   – Pre-soldered and programmed electronics
   – MicroSD card + adapter
   – Heated PCB build surface (requires eight soldered joints)
   – Motors
   – Nozzle assembly and extruder drive mechanism
   – 100m of 1.75mm diameter PLA filament (approx 300g) for printing with
   – 2 x 10m different coloured filament for printing in multi-colours
   – Universal power supply for all mains voltages between 110V and 250V
In addition, the Complete RepRapPro Tricolour Mendel Kit includes:
  – All the 3D-printed Tricolour Mendel parts

The above contents are subject to improvement without notice.  Complete Kits will always be provided with all components required to get you printing.  Hardware Sets will always be provided with all components required to get you printing except the 3D-printed parts.  The colours of the supplied filament will not always match those illustrated.
