After the beta release of multi-material and multi-colour enhancement kit, RepRapPro announces today the release of Tricolour Mendel - an open-source RepRap Mendel 3D printer designed to work with three colours or three different plastics at the same time.

This new design is derived from RepRapPro Mono Mendel, a successful model from last year. Its primary design goals were to offer a printer which is easy to expand in functionality, which is low-cost, fast to replicate, to assemble and to commission.

The Tricolour Mendel features more compact extruder drives and enhanced Marlin firmware. "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." In addition, the Arduino-compatible Melzi electronics are used for both the master and slave controllers.


  • Build volume: 210x190x140mm
  • Overall size: 500x460x410mm
  • Printing materials: ABS, PLA, 1.75mm diameter
  • Build surface: PCB-heated bed to reduce complexity of assembly and to ensure parts do not warp.
  • Computer interface: USB
  • 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.

A Complete RepRapPro Tricolour Mendel Kit, which includes everything you need to get printing in three colours or materials, costs £746.80 / €938.80 / $1088.80 (including shipping), lead time is 30 working days.

The complete kit includes:

  • 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 white PLA filament (approx 300g) for printing with
  • 2 x 10m coloured filament for printing in multi-colours
  • Universal power supply for all mains voltages between 110V and 250V
  • All the 3D-printed Tricolour Mendel parts

You can also order a complete RepRapPro Tricolour Mendel Hardware Set without the 3D-printed parts, for £671 / €848 / $988 (including shipping).
