I am just curious if anyone has printed anything in PLA and then dipped or coated it in two part epoxy or polyeurethane. I do not plan on doing this, but I just had to wonder.
I have a sculptor friend who uses putty epoxy to hand finish his PLA prints.
I saw a great blog post on finishing PLA parts with spray primer (wish I’d saved it!). The dude was doing two coats, sanding between coats, and his results were phenomenal.
If you really want to increase strength and heat tolerance, have your part nickel plated.
Or casted in Iron.
