Review on OVERTURE 1 mm TPU Filament by James Cypert

I've been using Overture PLA and PETG so I had to try it when I saw they added TPU and I'll add a few notes here as there aren't any There are still reviews. I have blue and it's a light opaque blue - not transparent at all. The price is good for a 1kg spool, for some reason most TPUs come on 800g spools so I'm happy with that. The coil is supposed to print at 210-230°C, but I'm having pretty big problems with under-extrusion and interlayer adhesion at 210-220°C. For reference, I'm using a Titan Aero and Volcano setup. At 230 it extrudes fairly well, but any bits that get stuck in the nozzle will slowly change color from light blue to green to tan to green due to yellowing from the heat. So if they work their way into the print, it's not good and can ruin it. . You may need to adjust your start/stop code or watch each print start with tweezers as you can't have a dirty nozzle with this stuff. The attached picture shows some of the baked slime coming out of the nozzle. I also have a design where I need to use the 'pause on layer' feature and this TPU doesn't offer very good interlayer adhesion on the pause layer. Otherwise, as long as it's at 230C and extruded properly, it's like any other TPU where you can't tear it by hand, even on single thickness walls. Overall, this is a decent material, especially for the price. I'll definitely try black once my other black TPU spool runs out as I don't expect the yellowing to affect it.
