Proff sez, "Markus Kayser built a 3D printer that works with solar power to heat up sand and form objects like a regular 3D printer, by taking the energy and the raw material directly out of the desert. He also built a laser cutter working with solar energy and a lens."
In mid-May the Solar Sinter was tested for a two week period in the deserts of Siwa, Egypt, resulting in the amazing footage above. It's incredible to think that the solar energy generated for both machines is used only to power electronics, servos and the mechanism that tracks the sun, while the power used to cut wood and melt sand is just raw, concentrated sunlight. While I fully understand the mechanics and science at work in Kayser's devices, there's something about them that just seems magical. Definitely head over to his website to explore more photos and info.

They can be annoying at best and a financial threat at worst, but there’s a way to take security into your own hands. One good example […]
