Quoted from mattosborn:To get that look they are tumbling the print in brass screws for many hours. It’s not really polishing... it’s adding brass from the screws. If you actually try polishing it like real metal, it doesn’t look anything like that.
I had issues with it clogging up my extruder, so I never got a complete print out of it anyway.... If you want a sample of it to try out, just send me your address.
I printed a bunch of wine charms for a party we were hosting (each charm had the person's initials in it). I used Colorfab brassfill and sanded it all the way down to 1500 grit. They came out very shiny and were nice and heavy so that you really couldn't tell they weren't polished bronze. I tried tumbler with walnut, and various brass polishes hoping to expedite the process. Unfortunately, lots of elbow grease was the only thing that worked for me.
