The aim of this design is to build a simple, cost effective (under $1000) and relatively compact large volume (m3) 3D printer that will use a pellet extruder to create art/design objects using shredded recycled plastics.

This small desktop machine is built inside a 300mm cube of 20mm extrusion. Work area is 14cm by 14cm. I used 400 step nema17 motors all around.

An OX-inspired mini desktop mill.

This Belt and Pinion actuator is a great example of how easy it is to convert your machine into a belt drive system.

The Acro Laser Machine Build

I built a motion control camera slider with the V-Slot® NEMA 17 Linear Actuator Bundle (Belt Driven)

This is a WorkBee 1000x1000mm with lead screws and Nema17's. It has a reduced footprint, with the geared Nema's inside the frame.

Very cheap CNC made from laser fired and bent parts.

We created an A1 ACRO Drawing robot specifically for the artist communities. It utilizes the popular ISO 'A series' paper sizes standards
