Sinterit Update

Remember those fellows building a new lower-cost laser-sintering 3D printer? They’ve been quite busy working on Sinterit.

SLS 3D Printing: At Home?

Patents related to the SLS 3D printing process are about to expire. SLS stands for Selective Laser Sintering, a process where a layer of powder is selectively melted by a laser, gradually forming an object. Up to now, the technology has been exclusively used by 3D Systems, who owns the relevant patents.    After Stratasys’… Continue reading SLS 3D Printing: At Home?

Pwdr: An Open Source Powder-Based 3D Printer

While the first open source personal 3D printers were plastic extrusion-based and recently we’ve seen several resin-based open source 3D printers emerge, we now see yet another 3D printing process appear in open source form: powder-based 3D printing.    The open source Pwdr project includes design for hardware and software to build and operate a… Continue reading Pwdr: An Open Source Powder-Based 3D Printer

The Solar Sinter Project

While home 3D printers typical heat/melt plastic to produce objects, Markus Kayser has developed an eco-friendly 3D printer for “desert manufacturing” using only sand as the print material.    The Solar Sinter focuses the heat of the sun to a small point using a large, sun-tracking fresnel lens. The focal point is so hot it… Continue reading The Solar Sinter Project


We’ve been following the folks at Open3DP for a while now as they proceed through experiments in 3D Printing. Lately they’ve been working on perfecting printing molds that have revolutionized the production of RepRap Prusa Mendel 3D printer parts. However, we now see they’re working on an entirely new project: an inexpensive, presumably open-source powder-based… Continue reading AdderFab!
