Open Cascade Technology

When you import a STEP file into a modern slicer like Bamboo Studio or PrusaSlicer, a hidden background process takes over.

Slicers integrate a specialized CAD kernel, uh, often an open source framework called Open Cascade, that reads the BRep equations and tessellates them into triangles locally, entirely behind the scenes.

Oh, so the slicer's actually doing the mesh conversion itself.

Precisely.

Don't we

have that with OpenCascade? Sorry, I said that to pick a...

So we do and we don't.

First of all, they actually have restrictive licensing.

Yeah.

So it doesn't actually...

The other problem with OpenCascade is that it doesn't have...

I don't know what the problem is.
