Flexing on TPU: The Best Flexible Filament Alternatives for 3D Printing

Video Description

TPU has been the go-to flexible filament for years, but is it still the best choice? In this video, I put TPU head-to-head against newer alternatives like PEBA, Morphlex, and PLA-HR to see which flexible filament really performs. You’ll see side-by-side comparisons, bounce tests, and real-world prints to find out where TPU still shines — and where the other materials completely out-flex it. Whether you’re printing phone cases, gaskets, flexible hinges, or even sports gear, this guide will help you choose the right flexible filament for your 3D printing projects. *This video is sponsored by PCBWay* Custom PCBs, 3D printing, and CNC machining!
