The PWDR 0.1 is a powder-based rapid prototyping printer, designed and initiated by the University of Twente. Its goal is to promote experiments and innovations in powder-based rapid-prototyping. The machine is ready to use both the 3DP as the SLS process with minimal adaption, although the printer is currently prepped for 3DP. The printer entirely consists of off-the-shelf components. It has a simple design and can be built within a couple of hours. The machine is easy and affordable to build, the entire collection of building parts for a Model 0.1 machine cost around €1000,-. PWDR’s software is able to convert a CAD model in a printable format. This file is then uploaded to the Pwdr micro-controller. The Pwdr Model 0.1 software is based on open source tools like Arduino and Processing.
