I’ve got a backlog of matte PETG to test and am going to get some of it done this weekend. I already had what I considered to be the most likely next Bambu filament dried, eSun Matte PETG, so here is an early sample. The one on the left is just for comparison as I didn’t have any Bambu samples printed, it’s Overture rock pla, which is quite matte. You can see the eSun is even matte-er.
So watch this thread if you are interested, I’ll post more as they get dried and printed.
