I have about 30 3d printed parts for a university project, they are printed in ABS. I plan on finishing them in plasti dip, but making them smooth first is the real issue.

If any of you have any experience with finishing 3d printed parts please give your advice.

My plan is to sand them lightly, then either dip them in acetone or use acetone vapor to make them smooth. Next I would fill any big defects with bog and use filler primer, then finally sand them and spray on the plasti dip.

that sounds like an awful lot of steps.

This is less steps than the post processing for professional 3d printed parts.

Now do they need to look pretty, be strong, or fit together?

And if you're just going to spray them with plasti-dip why do you need to smooth them with acetone?

They need to look pretty.

I know plasti dip can hide defects, but I'm not sure if it could cover the defects of a 3d printed part.

Making prototypes that look like something from production takes a lot of time.

> dip them in acetone
That works?

>> No.635859

I used the warmed acetone fumes method. It works well. Dont get to to agresive

Have you thought about "teasing" them with a blow torch? Just enough to make the surface "gooey".

I have no idea if this would work but isn't there some kind of varnish you could put on there that would simply give it a glassy finish?

You can paint a turd, but in the end, it's still a fucking turd.

MEK or GBL(BLO) dip

Do not dip them in acetone. You have the solution in your own damn pic. Acetone vapor bath is all you need.

>> No.637330

Op i also heard you could simply dip a cotton ball in acetone and rub it against the print. Some guys even started a kickstarter with a sponge at the end of a tiny acetone container stick and were massively funded if I remember correctly

>> No.637496

Put the print in a mason jar with an acetone soaked cotton ball beside it. That's all you need to make a vapor bath treatment. Takes about an hour or so to get a shiny finish.
