Very cool. Are these investment casts? Or are they reusable?

- paperfiber 3y agoInvestment castings, we break the mold off and recycle the ceramic. That way you don't need draft angles or other limitations.
- digdugdirk 3y agoHow does the ceramic recycling process work? I'm guessing just crushing and heating the ceramic does a decent job of separation, but there has to be some level of impurity leftover. Is there enough pressure in the casting process that you'd be worried about localized weakness in the tool?
