You cannot fail to be impressed with the innovation and future potential of this.
@asanyfuleno spotted it on the Llewblog this weekend.
We had been talking about 3d printing and modelling things in situ in unusual environments. Then this popped up.
When I talk about 3d printing to people and suggest that it can be distributed across the planet to solve all sorts of issues there is usually the challenge of power and raw materials brought up. Here Markus Kayser powers with the sun, bit electricity to drive the steppers and the power of the sun to melt the abundant raw material of sand. This is also combined with some human intervention. Tools do not have to be completely automated if a quick bit of hands on solves the problem.
It’s like a real life Minecraft crafting table!
