Hello, I'm trying to develop a consistent method for making props with my 3d printer, but i don't have a garage or adequate outdoor space for things like sanding and painting.
I'm working on an indoor sanding booth to keep from making my room a mess, but I found that many of the popular filling and priming materials either produce fumes which cant be filtered easily like sanded particles can, or require a large area to spray them.

Are there any options out there for coating that are safe for working indoors?

Sanding will always create dust, can’t get round that one. Depending on your available space could you get a small tent and work in there, obviously wearing ppe.
Fumes and rattle cans go hand in hand, you might be able to get a portable extractor fan to help, or maybe get an airbrush set up as I personally find them less fumes making than spray cans.

The only kind of paint that is okay in poor ventilation is acrylic.

But it needs to be sprayed from an airbrush. The propellants used in spay cans like Montana gold will also give off fumes.

Depends on a lot. Any cheap airbrush will work but the more expensive airbrushes last longer, have a better chrome coating, are easier to clean, and easier to replace parts that go bad. Up to you how much you want to invest. I use an iwata Eclipse to strike a good balance between price and function. Paasche or Iwata NEO are really good entry level ones. Harbor freight has some really cheap ones that aren't great but you're only out $20 if you F them up.

You also need a compressor. Timbertechs are really cheap but super reliable.

1 - You don't need to slather on "magic shell" coatings of bondo or resin. Its a technique some like. I don't. Its not a requirement by any stretch of the imagination. So if its a problem, just don't do it.

2 - That leaves you sanding. Go some where. Take your stuff, go to the park, go to the far edge of the WalMart parking lot, go to the highway rest stop at exit 22 or whatever, put on some music or an audio book, and sand away.

3 - Painting. Its been discussed already. Won't beat that dead horse.
