Introduction

The Mowi Printer is a foldable 3d printer, folded flat it is small, but opened up it can print big and with two materials. It also has a display for standalone printing. The Mowi printer is still under development so expect the files to change.

Current version Mowi v3 has a more sturdy Y-frame, the possibility to fixate the Y-frame to the Z-frame, a Graphic display, a smaller power supply, a wooden extruder , and a Z probe for auto bed leveling. It prints reliable with pla and abs. At the moment I am working on version 4, this version should be able to also print with pva and flexible filaments. I am looking into using mk8 hotends. These would also give the ability to swap the nozzle and they are cheaper and easier to source.

At the moment there is no build manual yet. I hope there is enough information to get you started on building your own Mowi printer. In the Step Assembly on Github you can see how everything fits together. Let me know when you start building so we can work on the documentation together. You can post any issues on the github. All help in improving the design and/or the documentation is very very welcome. Also the pictures and video are still from the version 1. I will try to update them soon.

Inspiration

The Design of the Mowi printer is based on the work of many other 3d printer designers, thanks a lot!!! Its inspired by Prusa i3, Ultimaker, FoldaRap, Cartesio, by flow and many many others.
