On: Ask HN: Any hardware startups here?

We are building a cyber foundry in Los Angeles to reshore American manufacturing. Using in-house composites, Rangeview 3D prints highly complex ceramic parts and pours molten metal into them autonomously. Our process can make components with material and geometric specifications no other metalic manufacturing process is capable of. We have worked with Rivian, Boeing, Airbus, and are aiming for military spares for planes like the F22. The founding team met doing VEX, FRC and Battlebots. https://rangeview.co/

That sounds very cool.

I have to ask - do you build parts for your machines using your machines?

[paperfiber → i-use-nixos-btw]

Of course, all good additive companies do

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

[paperfiber → digdugdirk]

Investment castings, we break the mold off and recycle the ceramic. That way you don't need draft angles or other limitations.

How 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?
