Alright, take 3. Polypropylene beads and fine grit.
Before shots.

That’s progress now you have to just find a happy medium. Pun intended

Polypropylene beads didn’t work out well so we are now going full washing machine. Tumbler is loaded with a bunch of denim scraps and fine grit, added water after the photo.

Ooo I’m excited for this one
Your experiments have become an awesome pastime to follow

Update! Denim did nothing even after like a month. I tried various other media, round ceramic beads, ball bearings, etc and on the spinning tumbler it always ended up with chips in the 3d print.
I bought a vibratory tumbler a few days ago. I added a mix of walnut shells, corncob bits and fine grit. Then I tossed in a couple of rough stainless steel 3d prints. Initial observation was it looked like I needed more mass in the tumbler and I had a bunch of F- grade poo counterweights so I chucked them all in.
It looks like a cat littler box from a cartoon.
But after two days of tumbling this part came out and it’s very shiny compared to a raw part.
Here’s a comparison of a raw part and the tumbled part.
And a nice shiny angled shot of the tumbled part.

My wife and I got 4-5 measuring spoons several years ago on our registry, and they have this coating that has started to flake. I have a wet rotary tumbler that I’ve used a handful of times, and so threw this spoon and some metal ball bearings. This is after maybe 3-4 hours of tumbling, and there are some nooks and crannies that the balls can’t get into, it makes me wonder if there is a media that would be best. On another note, I wonder if @da5id can chime in on why One drop decided on using pyramids (hence pyramatte, right?) or maybe talk about their method?

Is that a dumpster fire half?

Yes that’s a failed dumpster fire 3d print. When RCS closed Jeremy gave me the CAD file so I could make my own.
I eventually got it working but had a bunch of failed prints first. So used one of the failed prints to test the tumbling.
I tried ball bearings in my rotary tumbler but unfortunately 3d prints are more delicate so it ended up chopping them. I haven’t done the plastic triangles yet, but I did triangular ceramic media and those also chipped the prints.
