I'm looking to get silver dollar sized medallions with raised figures, like unicorn, sword and shield, etc... It's to press into clay sand to pour pewter into. So no super fine details.
All of the online services want a 3d or sls file. The whole reason l didn't want to do it via library is the pita of creating sls files.
Don't know what that is. I want several silver dollar sized medallion with a raised (1/8- 1/4 inch) figure such as unicorn, skull, crossed swords, etc ...
Why don't you get a few medallions and then do the mold casting off of them? It may be easier than 3D printing them. I did a quick google search for skull and crossbone ones and a few items came up. You can usually get them pretty cheap.
