Solar Sinter by Markus Kayser

Solar Sinter” is a 3d printer by Markus Kayser that lives on sand and sun. It’s based on selective laser sintering (SLS), using Saharan sand as the medium and sunlight from a Fresnel lens in place of laser.

If you jump to 1:36 in the video above, Markus appears to be using MakerBot electronics to drive the Solar Sinter.

Markus writes:

In a world increasingly concerned with questions of energy production and raw material shortages, this project explores the potential of desert manufacturing, where energy and material occur in abundance.

In this experiment sunlight and sand are used as raw energy and material to produce glass objects using a 3D printing process, that combines natural energy and material with high-tech production technology.

Solar-sintering aims to raise questions about the future of manufacturing and triggers dreams of the full utilisation of the production potential of the world’s most efficient energy resource – the sun. Whilst not providing definitive answers, this experiment aims to provide a point of departure for fresh thinking.
