Open Source, Powder-Based 3-D Printer Has Full-Color Potential

PWDR is an open source, inkjet-based 3-D printer that has the potential to bring a Wizard of Oz-like range of color to the previously black and white world of additive fabrication.

Unlike the MakerBot and RepRap printers that build objects by melting plastic, or the Form 1 that uses a laser to cure resin, PWDR works just like a desktop printer. An HP inkjet deposits a liquid binder, mixed with ink, onto a layer of white gypsum powder. After the printhead passes, a roller bar drags a thin layer of powder across the surface and the process repeats a couple hundred, or thousand, times.

Pwdr Model 0.1

Pwdr is an open source powder-based rapid prototyping machine. 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.

Neuer Open Source 3D-Printer – mit Pulver statt Plastikdraht

Yvo de Haas, ein junger niederländischer Ingenieur, hat mit dem Plan B einen Drucker vorgestellt, der nach dem selben Prinzip funktioniert wie die Z-Printer: Über einen Tintenstrahldrucker-Druckkopf wird gezielt Bindematerial in ein Pulverbett gespritzt. Schicht für Schicht wird Pulver aufgebracht und dort, wo später Material sein soll, Binder aufgebracht.
