Markus Kayser has developed a 3D printer which harnesses the power of the sun to sinter layers of sand to create 3D parts in glass! Dubbed the Solar-Sinter, the semi automatic 3D printer focuses the energy of the sun through a large fresnel lenes and melts the sand, thus turning it into glass, to form 3D objects. The machine in the video is the second machine Kayser has built and was tested in the Sahara desert near Siwa, Egypt. Video after the jump….
“This process of converting a powdery substance via a heating process into a solid form is known as sintering and has in recent years become a central process in design prototyping known as 3D printing or SLS (selective laser sintering). […] By using the sun’s rays instead of a laser and sand instead of resins, I had the basis of an entirely new solar-powered machine and production process for making glass objects that taps into the abundant supplies of sun and sand to be found in the deserts of the world.”
“The machine and the results of these first experiments presented here represent the initial significant steps towards what I envisage as a new solar-powered production tool of great potential.”
This is a truly unique approach to 3D printing and we hope Markus continues with his development of his Sun powered machines.
