Open-Source 3D Printer Pwdr Takes on MakerBot, Offers New Materials
There’s a new open-source 3D printer in town, and its name is Pwdr.
In a change from the technique used by MakerBot 3D printers of extruding plastic onto a platform layer by layer, Pwdr operates like the expensive industrial powder printers. This opens new doors for the consumer 3D printing market.
A whole new range of materials become available for experimenting with open-source rapid-prototyping; for example, when using the 3DP process: gypsum, ceramics, concrete, sugar, etc. And when the SLS process is fully supported, plastic materials like ABS, PP, Nylon and metals become available as building material.A Hewlett Packard inkjet cartridge is used for the deposition of binder. The cartridge can be refilled with custom binders using a syringe. A custom binder of 20% alcohol and 80% water has been proven to work.
The Pwdr Model 0.1 consists of chassis, tool head and electronics. 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 and modify. Building a Pwdr Model 0.1 machine costs about €1000.
