How do I smooth 3D printed objects without using dangerous stuff? Sanding is too much work. I'm scared to use Acetone. What about plastic fillers/putties? What about Testor Plastic Cement? What about Weld-On plastic cement?

Wood filler is a easy method, sands easier than the epoxy stuff. You just have to make sure to seal it after.
What kind of wood filler do I need? How can I seal it?
Acetone is not that scary. Don't breathe it in, no open flames in the area. It's not that easy to ignite though, I once forgot about my pipe, and I was smoking while brushing on acetone. Not only will acetone smooth, it will 'harden' the layers together to help prevent delamination. And it's fairly cheap and very easy to find.
Try a soldering iron with a flat tip. This works very well but obviously don't keep the iron on one place for too long otherwise it will go straight through!
You must have pretty decent skill if you're using soldering iron to smooth lol.
Also, anyone has any experience with sandblasting with fine grain? Will it work?

Really? It'll give awesome results. That's really all that matters, right?Quote:

the epoxy just brushes on - no sanding or other faffing about required.
To be honest I don't know why people are so obsessed with buggering about with printed things. Mostly the finish is pretty good anyway.
You could just use thinner layers.
In fact, it works surprisingly well! I use a wood burning soldering iron that came with maybe a dozen or so tips that get screwed on. Once you dial in the right temperature, you can smooth, cut or weld pieces together. I've only worked with PLA though.
