Markus Kayser - Solar Sinter Project

This doesn't look quite ready for prime time just yet, more of an art project/proof of concept stage for now, but...

The concept of 3d printing using sand (assumedly very pure sand, maybe not the stuff that's surrounding the 3d printer in the open desert) is pretty outstanding there, and the bowl looks awesome.

Mostly similar video but with slightly different edit after the jump...
