3D Prints of Hood and Door Bumper Stops with TPU 95A
I bought a used machine on CL to start. No manual. I messed around about 3 weeks, adjusting things and watching youtube about printing. I was scared to try. Finally I tried, it was like asking out a girl for first time. :)
ClayDart, it also could be trying to print over hangs and making spaghetti. TPU supports are nearly impossible to cut and remove. Designs need to work without supports. The hoodbumper is an example where printed top down, with draft angle to build stairs to support edge rim. Without draft, edge would have spewed in air.
I think moisture creates bumps and bubbles.
I keep filament in plastic cake tote, along with desiccant. Dry desiccant in oven 150F.
Fuzz seen in tie rod boot ID, is from no filament retraction. I added 0.8mm traction and that eliminated fuzz.
