Review on 🚀 Enhancing Additive Manufacturing with Polymaker TPU Filament 2: Unleash Creativity and Performance by Rob Rogers

In general, TPU has a reputation for being more difficult to print. I expected to have to do a lot of work to get a clean print. To my surprise. I really had no problems. My first test prints came out clean. I printed a temperature tower to find the best temperature for it and tweaked the settings to minimize stress (usually TPU is quite viscous). Then I immediately started to get good details out of this material. The material is very flexible. It doesn't "stretch" much. The thread itself has the property of stretching/elasticating (in addition to being flexible) but once you've created a few layers it doesn't actually "stretch", it's basically just flexible. It's VERY strong and the layer adhesion is excellent (you'll find you can't separate the layers.) I should mention that I use this on a direct drive printer. Bowden drive printers are probably more common. The Bowden drivers must "push" the filament through the Bowden tube, and the rubbery nature of the filament can make this difficult for some printers. Direct drive printers have the filament feed gear directly on the print head (no bowden tube) so they have better filament control. I've never tried typing this on a Bowden powered machine, so I can't comment on how well it works.
