The Saharan sun is a powerful thing and Markus Kayser decided to demonstrate itspower as a manufacturing tool with his Solar Sinter project. Both the energy and raw materials are gathered from the immediate vicinity to create 3D printed objects in glass.
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.
