3D printed sand moulds.

(1/2) > >>

nrml:
3D printed patterns for mould making are fairly common these days but I had never heard of directly printed sand casts until today. I was completely blown away by the quality of the end product. I think a lot of folks here will find this very entertaining despite the really awful background music.

Homebrewer:
That's pretty awesome!  Thanks for sharing

I've done the patterns for sandcasting it worked out not bad.

NeoTech:
Well the solution they print is a mix of waterglass some solvent and a hardener that is propriertary.. when you figure out the mix, making a powder printer is really not the hard part.
