EV3Dprinter – LEGO MINDSTORMS and a 3D Pen

New and improved EV3 3D Printer using a standalone 3D pen. Improvements include direct motor drive to eliminate slack caused by gears and a tighter less prototype like assembly. Click SHOW MORE for LINKS and ANSWERS to some questions…

The complicated math engine was programmed by my friend Thomas Madeya from Germany
The UI and variation to the core program was done by myself.
All of it is programmed in EV3 and the MINDSTORMS project file is available on my INSTRUCTABLE

The EV3Dprinter project has it’s own Facebook page here:

Pen used here is the 1st generation 3D pen available on Bangdood, it uses 1.75mm ABS filament.
