Ultimate Guide to Flexible Filaments for 3D printing (TPU edition)

Flexible filaments are awesome (Part 1). I printed and abused so many TPU parts on video that you'll feel like you printed them yourself. Learn some cool applications for flexible filaments and a cool slicer trick to help you print phone cases.

Btw, this is only part of the story! This video is actually only like 1/3 of the adventure. I'll be covering more filaments, more cool tricks and TPU printing tips, in future videos, so make sure you subscribe!

-EXTRA INFO-

I will include printing tips for TPU in the next video. Printing TPU 95A is possible on a Bowden extruder, but it may not be 100% reliable. Your best shot is to make sure the spool can spin freely, disable retraction, and print slow, like 10-20mm/s. I would guess the 90A and 85A variants are going to be more trouble than they're worth on a Bowden extruder (though I haven't tried).

I mention in the video printing 100% infill. I usually say "100%" in my head, but actually set it to 95% in the software. If your extrusion isn't calibrated perfectly and over extrudes you'll get a blobby mess at 100% (here's an example 100% infill print: https://bit.ly/3P2cIuB )
