Review on High-Quality Red TPU 3D Printing Filament With Dimensional Accuracy For Professional Results by Chase Shetler

This is my first TPU material so I have nothing to compare with. However, my first TPU part was run with standard PLA settings and it printed just fine. My second print was a temperature testing box. In deed, this filament likes to be extruded at colder temperatures. I started with 230C and dropped to 210F at a height of about 1 inch or so. The upper part of the test was much more consistent than the hotter temperatures. This filament is pretty sensitive. It will even bubble at 215C, so try keeping this filament at around 210F. I haven't done a low temperature test yet, but this is where I keep this filament.As far as print speed, Quality doesn't seem to vary much between 30m/s and 92m/s. However, you can't push this filament any faster than that. I've pushed the filament from 100-200m/s and it fails to extrude. You can increase temperature and extrusion rate, but that will only bunch up the filament inside the extruder and you'll have a bigger mess on your hands. Why 100-200m/s speed? Well, I do lots of test prints and prototypes, and finish is of no concern. I print prototypes at about 200m/s, and this filament can't be pushed this fast. Keep it below 92 m/s.You can cut this filament with scissors. Why is this important? I have a Makerbot with "Smart Extruder" and the heat block is encapsulated inside the extruder body, and this filament can roll and curl up inside. This is a dangerous situation. Make sure the end is "square" and straight before loading this filament.Beware of loading and unloading precautions. I frequently change filament and this filament is a lot trickier to load and unload, so it's not load/unload friendly.Otherwise, this filament is pretty nice.
