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

Video Description

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 ) ==TIMELINE== 00:00 - Introduction 01:52 - TPU & Shore Hardness 03:15 - Filaments 101 04:50 - Cura Dual Extruder Trick 06:30 - Breaking Stuff 10:52 - Fun 90A prints 11:27 - Phone Case Slicer Hack 14:13 - Phone Case showcase 15:48 - Closer Stuff in this video: * SainSmart Teal TPU (95A): https://amzn.to/3C8Ad2y * Polymaker Gray TPU (90A): https://amzn.to/3JUp1bv * NinjaTek NinjaFlex (85A): https://ninjatek.com/shop/ninjaflex/ 3D Models: * Infinity Cube: https://www.printables.com/model/83187-tpu-fidget-infinity-cube
