    How to smooth 3D printed objects without using dangerous stuff?

    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.

    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?

    Seal it with some clear spraypaint, like krylon crystal clear.

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