OK so i'm jumping waaaaay ahead of myself here since my printer hasnt even arrived yet (in transit due next wednesday), and i obviously need to learn to use it first. But, one of the things on my list to try is printing with the flexible filaments. The main reason, is that i'm a model maker, and something i'm working on needs some rubber tires, in a size/scale/pattern that simply no-one makes. They'll have a diameter of about 50-60mm, with a fairly simple zigzag patterned tread (simpler than regular car tires). Most of what i've read about flexible filaments, have said they have quite a glossy finish when printed. Thats something i specifically dont want, I want something that looks like regular rubber. I guess i could use sandpaper to get rid of the gloss, but dont know if that will be effective. Does anyone have much experience with flexible filaments and can maybe point me in the right direction? Ninjaflex seems the most popular, but theres also Flex Eco-PLA, Flex PolyEster (available in different shores which is interesting). Any others? Thanks.
