Pwdr Model 0.1

thingiverse

Pwdr is an open-source 3D printing machine designed to promote experimentation and innovation in powder-based rapid prototyping. It's compatible with both the 3DP and SLS processes, requiring minimal adaptation. The printer comes fully assembled using off-the-shelf components, making it easy to build and modify at a low cost of around €1000. The accompanying software converts CAD models into printable formats for the Pwdr Model 0.1 microcontroller. Easy-to-use software controls the printing process, with open-source tools like Arduino and Processing as its basis. A range of materials is available for experimentation, including gypsum, ceramics, concrete, sugar, plastic materials like ABS, PP, Nylon, and metals. The printer uses a Hewlett Packard inkjet cartridge to deposit binder, which can be refilled with custom binders using a syringe. Key specifications include a maximum build size of 125mm x 125mm x 125mm, a print resolution of 96 DPI for 3DP, minimum vertical step sizes of 50µm, and an average printing speed of about one minute per layer. To operate the printer, follow these steps: ensure the power supply is disconnected, convert your model to printable data using Pwdr_GUI Processing software, upload the print file to the microcontroller, clean and reset the machine's position, fill it with powder and binder, connect power and start the print job. Once completed, remove the printed part after allowing it to rest for a few hours. Overall, Pwdr offers an affordable, customizable 3D printing experience with significant potential for material experimentation.
