With its 85A Shore hardness, this premium filament is tailored for a wide range of printing needs, from professional to hobbyist uses. Why Choose Siraya Tech Flex TPU 3D Printer Filament? Exceptional Flexibility and Strength: Our Flex TPU 85A filament combines rubber-like elasticity with thermoplastic durability, perfect for versatile projects. And is significantly softer than commonly available 95A TPU. User-Friendly Printing: Designed for hassle-free printing, our 3d printer filament 1.75mm ensures an uninterrupted, smooth printing experience. Advanced Moisture Protection: Thanks to its aluminum packaging, our filament stays protected from moisture and external factors, preserving its quality for longer. Wide-Ranging Utility: Whether it's custom footwear, protective phone cases, or medical devices, the Flex TPU 85A is your filament of choice. Safety First: Prioritizing your health, our biocompatible filament is suitable for sensitive applications like medical device manufacturing. Review: I bought this to try making custom hard case inserts, similar to another reviewer. I was largely unsuccessful getting this to print at 270C on my 0.4mm nozzle (it immediately clogged), but after switching to 0.6mm I have had no issues at all. At the 270C settings, this material really can't do overhangs, but after doing some testing I found that it works fine at 15% infill with 4+ top layers. At lower infills or fewer top layers, the infill texture shows through and there can be gaps in the top layer. Because of the foaming aspect, prints seem to use less filament than if printed in regular TPU. The texture of the finished product is similar to EVA foam and looks very clean after cleaning up some errant strings. It is perfect for my use case, and it's so nice being able to print an exact fitting insert! In the past I used sheets of packing foam, and it always was a pain trying to cut an exact fit while maintaining a clean look. Since the surface comes out relatively smooth it's also easy to wipe clean. TLDR; this stuff is great!
