Straight from the printer as often as possible.
I'm not above taking knives, chisels, drills, and saws to prints as necessary, but this is usually reserved for functional/not often seen prints.
If I am looking to improve surface finish there really isn't a substitute for sanding. I deal with the fuzzies with my hot air solder station. Just wave some hot air over the sanded surface and you'll get quite a bit of shine back.
Now that I've (nearly) finished building a Voron I am somewhat tempted to give vapor smoothing a try.
Hot air station is a great idea damn. Do you ever have to deal with going too far? I'd be scared 😲
Practice on a failed print to get the hang of things first!
I haven't run into any issues, but I tend to print 3-4 walls so maybe that helps. My hot air station has adjustable temperature control and I keep the temps down - usually around printing temperature. I also don't stay in any one spot too long. You can see the surface finish change sheen as you move on and off a spot and its temperature changes.
I can't take credit for the idea. I either read it in a printing community or it was a natural outgrowth of people saying, "use a lighter" and me not owning a lighter.
What do you think of an acetone vapor bath?
I've never done it, but I also wasn't printing with a material that even supported it until I started building my Voron. Now that I'm nearly done I am wrestling some with going back to PETG (somewhat more likely to be recycled if you put it in your recycling), PLA (could maybe be composted if it doesn't get sorted out/will eventually break down in. A landfill), or ABS/ASA (no hopes or dreams here, but man my Voron does seem to print it well).
I have 6 kg of ASA for some functional prints. I'm sure I'll vapor smooth some of it. Printing hassles of ABS/ASA aside, vapor smoothing seems like it offers amazing surface finishes. I really don't know why you don't see more of it? If you don't need dimensional accuracy it should be a big time saver.
