@davebauerart 9 or 10 years ago I showed off “rubber stamps” at MakerFaire Pittsburgh. I used NinjaTek filaments which were the first on the market. I got my best results with the original NinjaFlex which was the lowest durometer available. Cheetah was a little harder I think, and worked ok too. There was a third even harder one whose name escapes me. You’re right you need to print quite slowly, and I used a little retraction to cut down on stringing. #maker #3dprinting #rubberstamp #makerfaire
