The first open source powder 3D printer

So the first powder printer appeared in the open source. Developed at the University of Twente (the Netherlands). The printer can print powder with a binder and with minimal rework - sinter powder.
The current printer version is prepared to work with the binder. The printer has a simple design and is built from standard available components. You can collect it in just a couple of hours. Components will cost around € 1000.
When working with a binder, it is possible to use powders of gypsum, ceramics, cement, sugar and others. After adaptation to sintering, you can work with ABS, PLA, nylon and metals. For the binder, use a head from an HP inkjet printer, which the authors fill with a syringe. I think this is where the experience of screwing to the ink supply systems of the CISP is useful. A mixture is used as a binder - 20% alcohol + 80% water (vodka ?!).
