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

[curious aardvark]

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.
