This is kinda the opposite of what all the tutorials on the web focus on…
I recently 3d printed a paint pallet. I plan on using it with acrylic paints to teach my son how to build plastic models.
I don’t want the acrylic to stick to the pallet, so I’m trying to figure out what to use. I’m thinking I can just polish the plastic using a car wax/polish.
Any other ideas from my friends on the forum?

Print a pallet mold, then cast in silicone. Actually, wonder if acrylic paint sticks to flex seal?August 26, 2019 at 6:36 pm #110941
Oh! That’s a good idea. I have some of that in a can somewhere. I can test it on something.August 27, 2019 at 8:54 am #111030
Another thing to try if that doesn’t work. “Paint” the trays with a thin layer of clear silicone caulk. Hell, we could be overthinking this and a few layers of polyurethane would work. 🤷♂️August 27, 2019 at 10:54 am #111044
It looks like I could spray it with a clear acrylic varnish. Once it’s dry, it’s supposed to be super hard and impervious to other liquids.
I have a couple of things to try now. Probably won’t be until this weekend before I can get to any of them.
I’ve already printed a paint tray that I designed:August 29, 2019 at 5:18 pm #111401
Acrylic pretty much always sticks to acrylic. Maybe not particularly well, but it does. So just a varnish wouldn’t do. However, if you get it extremely smooth you wouldn’t even need it. But we are talking almost mirror polished (if it were metal).
I think the silicone idea is the easiest and quickest. Either casting or just covering the pallet with it.August 30, 2019 at 7:58 am #111462
The casting in silicone keeps popping up. I’ve never done this. Does someone have a good tutorial on how to turn my 3d print into silicone?August 30, 2019 at 8:27 am #111465
Oh. I guess I just need to recreate my paint pallet as a negative. Then pour the silicone over it. Instead of the silicone being a mold, it will end up being my finished part.September 3, 2019 at 1:20 pm #111899
Hopefully I don’t disappoint anyone… My wife reminded me that paint pallets are 5 for $1 at the dollar store…
Maybe I’ll get around to testing something in the future.September 5, 2019 at 1:07 pm #112175
Tell her that the dollar store just isn’t as much FUN! 🙂
