Yeah - I tried that technique to change the inherited profile setting on a new profile to an existing master printer profile that I have, but when you do that, the new profile just disappears in the UI. If you reset it back to a system profile, it reappears. I can’t understand the utility of that.

Awesome video, very cool to watch FDM 3D printing used in a modern manufacturing process. That said I don’t think “Mass producing” is the correct term here. A boutique sign company offering custom, chiefly handmade signs (after the printing is complete) is the opposite of mass production: A lot of work is going in to each of these and they probably aren’t churning them out.

FreeCAD cannot perform any operation to solidify a sketch that would result in more than one discontiguous solid.

Link can do this with a single sketch+pad (which is what I was referring to in the original post)

I agree! It does enforce being clean and thoughtful about your design. But the inability to use a single sketch for more than one operation still bugs me. I loved being able to plan out and see all (or at least multiple) features in a single sketch in Fusion. In FreeCAD I can only figure out how to do this by making a master sketch and then projecting single features out to multiple other sketches, which works, but like everything in FreeCAD, just takes more time…

I also used SuperSlicer until I recently tried OrcaSlicer and was very impressed. The developer of SuperSlicer recently quit his job to work on it full time though, so I imagine it will start to catch up in features soon.
