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.
At long last, Make has the Egg-Bot Kit in the Maker Shed! The Egg-Bot art robot was originally designed by Bruce Shapiro and is purpose built to draw designs on round objects 3cm to 10cm in diameter. Use it to decorate eggs, light bulbs, ornaments, golf balls, and (with some work) even wine glasses! The laser-cut tool holder can accept fine point markers, engravers, and a host of other drawing apparatuses. To use it, simply assemble the kit, adjust the holder to fit your object, plug in your computer, use the open source program Inkscape to create your design, and hit the button! Before you know it you’ll be creating art on unique objects like never before!
