Show HN: I built a synth for my daughter

As someone who has never 3d printed anything, I'm surprised by how clean the case looks as opposed to what we usually see. Why is it so smooth?

Sanding and polishing, likely.

The surfaces you're seeing in the pictures are almost all the "bottom" surface that was printed directly on the build plate. It basically just picks up the texture of the build plate and is otherwise smooth. That's actually a fairly bumpy build plate they printed it on (which lots of people like for aesthetic reasons).

That said modern 3D printers are good at producing pretty nice parts these days, especially if you print with small layer heights. You might be underestimating the possible quality of 3d printed objects.

Nah, it just came out like that (i printed it :D)

We experimented with ironing, but you can't see it in those views. The A1 is a pretty good printer OOTB. There were a few iterations on the case design though to optimise the edges.
