The horns printed fine but that fuzz is a mess. Not sure it will clean up easy.

After some cleanup. Not much better.

3d printing mavens… any tips for sanding PLA prints down to a smooth finish? @divalbanerjee @h_thoreson @chenoehart

Much excite. Printing TPU for the first time. If it works I’ll be able to design my own tires 🥳😱

Just a simple rubbery washer to start with.

Yeah. It's neat if you can get it to work, but it takes quite a bit of fiddling to get it to work.

My first one is pretty satisfactory

Decent compliance, rather stiff at normal resolution printing with 60% infill. I bet I could get much wider range by messing with infill density. But clearly settings need work. But unlike PETG this feels different enough as a material, it’s worth mastering.

Ah, yes. You are using a bought printer with software-provided settings. That tend to make things easier.

The real fun with TPU is in multiple extruder printers, where you can have a solid main object with embedded soft inserts. But one extruder should work well for tyres.

yeah I was already thinking of getting a dual extruder machine just for that idea... heterogeneous material property composite parts would be a lot of fun
