3D printed sand moulds.
« on: September 22, 2016, 06:03:48 AM »
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.

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.

A friend has a business that re manufactures pumps. He went from 4 guys in a pattern shop to one guy and a  Z-Corp printer to make impeller patterns! Still sand casting, but the Z Corp printers work by fusing powder wit glue/ink. Nice because you can print in colour if you want..

Google Machinable Wax's 3D printing wax filament, it's here already ;-)
No list of equipment, it wouldn't fit ;-)
