The Ultimaker is a RepStrap with the following key features:

  • Moving Bowden extruder, allowing tall models to be printed very fast.
  • Parallel kinematics, all motors are stationary, moving mass is very low, allowing for 500mm/s travel rates.
  • Largest build envelope for its footprint (210*210*220mm print volume, single toolhead mode).
  • Easy to assemble.
  • High accuracy printing (down to about 50 micron in every direction)
  • Well thought out, production ready design.
  • Ships with official Arduino Mega 2560. Soon to ship with Open Source Pololu stepper driver replacement (open source upon first shipping).

This page is a development stub. Please enhance this page by adding information, cad files, nice big images, and well structured data!

The Ultimaker has its own Wiki, which can be found at: wiki.ultimaker.com. Documentation of development and research should be done on the RepRap wiki, however. For help on assembly, troubleshooting, spare parts or modifications contact Sam Bianchi Bazzi at: http://manufat.com/ultimaker-italia

Drawings of the laser cut files are available on Thingiverse. Parts lists can be found on the Ultimaker wiki].

High accuracy

Because of the bowden system and low-mass moving parts, the same amount of layers can be printed as is common. This means that the Z-resolution can be the same, e.g. all the way down to a 10 micron layer height as any other printer.
