Review: This stuff is RAD! - I love this stuff. It works great and creates a neat foamy texture. I use it to make vibration dampers for motorcycle parts and knee pads! They offer print profiles, none for the printers I have, but its easy enough to peep the json and set the baseline for your printer assuming you use orca slicer. It will string no matter what, dont even bother with retraction. The filament foams so its going to spill out of the nozzle, you can see in the pictures. Just plan on some post processing. I will also say that the adhesion is very very strong. Much more than the regular tpu I have used. I ruined a smooth carbon-fiber look build plate with it. Printing over packing tape might be a good idea. I tried glue but that didnt help the bed ruining conditions. Depending on your printer it might also help to have a bearing roller for the spool. its very soft. Technically not supposed to go this low of durometer with my Kobra S1, but it works fine.
Review: Seriously Great! - This is some genuinely great stuff. It took a bit to dial in the settings but after that it prints great. I recommend looking at the user guide for this on the Siraya Tech website. At max expansion, it’s less than half the density of regular TPU and really is fairly soft and super squishy. It also has a cool foam texture that hides layer lines. Doesn’t string at all and has great layer (and bed) adhesion. In fact, the bed adhesion is so good it peeled some of the PEI coating off 😅. It’s defintely weaker and less tear resistant at max expansion but it’s still super strong. The main problem is the fact it oozes constantly, which is due to it expanding. It’s honestly not much of a problem but it does effect the surface quality across gaps. Also, like every other TPU, it can’t do overhangs well bc the filament droops down.

## Features

- Superior Flexibility & Toughness: Siraya Tech's Flex TPU 85A 3d printer filament excels in flexibility and elasticity, making it ideal for durable, bendable 3D prints. Perfect for softer, pliable projects.
- ISO 10993 Tested: Our Flex TPU 85A has undergone testing according to ISO 10993-10, -5, and -23 protocols. These tests evaluate biological responses to materials, providing data on potential biocompatibility. This testing helps ensure peace of mind when printing for external-use wearables and devices.
- High Flow, High Speed: Designed for high-flow, Flex TPU 85A filament enables quicker prints than typical TPU 95a, blending speed with stellar outcomes. For the optimal printing experience, we recommend using a direct drive style extruder.
- Long-Lasting Quality with Special Packaging: Our Flex TPU 3d printer filament is sealed in moisture-resistant aluminum resealable bags, preventing water absorption and ensuring up to 3 years of shelf life and consistent print quality.
- Versatile for Various Applications: From custom footwear to medical devices, this Flex TPU filament 1.75mm meets diverse needs in creative and industrial settings. And compatible with most 3D printers, it guarantees a smooth and reliable printing process, suitable for both beginners and experts.

### ⭐⭐⭐⭐⭐ This stuff is RAD!
*by R***S on December 2, 2025*

### ⭐⭐⭐⭐⭐ Great for hard case tool inserts
*by E***L on December 2, 2025*

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!
