Beyond PLA and ABS? (vlemmy.net)
 

I started 3d printing back when you had to build it all from scratch, and it seemed ABS was the only filament to be found. PLA came along soon enough and made things sooo much easier. Then came some more exotic ones like TPU or Nylon I think, but I never tried them out because they seemed pretty niche.

But now I'm getting back into it after some time and am seeing PETG popping up more and it seems to have become one of the mainstream materials now.

Are there any other key materials I should become aware of these days? Has PETG started to replace ABS as a superior "high-temp" filament? Does anyone have experience with these?

OnShape is my go-to. It's what I taught my students when I was a TA for an introductory engineering class at college, and they could pick it up in about a day.

Can do just about anything a "professional" cad suite does, but it's free, works in a browser, and is generally so much better designed so you don't have to fight against the UI to get anything done.

Why plastic washers instead of springs? Is the bed sagging due to the washers deforming with heat?

Wait so what was the trick to save time and filament? Just rotating the part to use fewer supports?

Wait, Gormenghast has Science fiction? When does that show up? I only read the first book so far and don't remember a lot.
