Open Source Cyrus 3D printer features simple design, smooth operation, rigid nice-looking aluminum casing, industrial rubber heater and large build envelope (250 x 280 x 300mm), and can be operated standalone in either home or office.

It's creator, London based sasan believes "3D printing belongs to the world and each person should be able to have access to it. From kids to entrepreneurs who have great ideas but cannot afford prototyping." With this philosophy in mind, he keeps everything open source that all of the parts can be purchased worldwide with different reprap retailers.

Using open source hardware such as universal extruder from QU-BD team, T-slot building systems from Makerbeam and LCD Smart Controller from RepRapDiscount, sasan is able to keep the Cyrus low-cost and accessible for everyone.


  • All screws/nuts: M3 size
  • The rods: 8mm thick steel rod
  • Stepper motors: standard high torque nema 17
  • Electronics: modified RAMPS 1.4
  • All printed parts will become open source
  • The XY movements are in a H-Belt configuration

Check out below the comparison of Cyrus 3D printer and Makerbot Replicator 2:

Cyrus is provided as kit and assembled on Kickstarter, the Cyrus kit single extruder costs £449, and an assembled Cyrus 3D printer (single extruder) costs £699. You can also add the LCD panel ($40), dual extruder ($55), heated bed ($55) if you need. Check more here on Kickstarter.

Great thought. Awesome blog for all beginners. As this printer is very cheap and anyone can afford to learn 3D printing. You can also buy a very cheap Ideawerk Plus WT280A 3D Printer with FREE PLA Filament.

I think Stratasys use the H bot X-Y design for the Mojo so it would be interesting to see if there are any license agreements in place there. You could use the Core X Y design which is a slight variation.

The X-Y axis design is very simple and elegant however it might be a problem with the patents Agilent (at that time and now Verigy / Advantest) has for the H-shaped belt. They use this type of X-Y axis configuration in a multimillion dollar equipment for electronic testing - Verigy 93000. http://www.freepatentsonline.com/6756778.pdf http://www.freepatentsonline.com/20030102857.pdf
