This is a Loki headpiece commission that I did. It's not completely finished here, I'm sending it to the client for the finishing details.
She's wearing it to San Diego Comic Con.
All printed in Esun Natural PETG.

nice! is that just a red oxide primer?

very nice!

Thanks! And yes, it is Jim. It's Rustoleum brand, 2x coverage kind. I really like it.

How is PETG to sand in comparison to ABS? Are there any solvents for it that smooth the surface a la acetone:ABS?

They sand i a similar way. PETG may gum up the sandpaper a little bit more, but not dramatically. I have used "weld on 4" acrylic cement for bonding parts, but haven't tried it for any smoothing effects. I'm going to have experiment with that.

I dunno, I'm happy to accept the health risks of acetone, but messing about with Weld On is a different story. It's probably some devil's brew of solvents that are probably none too good for you. Here's the MSDS: http://www.tapplastics.com/uploads/pdf/ ... %20New.pdf

Vapors are heavier than air, which is good. Trichloroethylene doesn't seem to be something you want to vaporize and breathe in: https://en.wikipedia.org/wiki/Trichloro ... al_effects

Yeah, the stuff is definitely strong! I always wear a respirator when I use it, but after reading that, I feel a bit more wary.
