The TPU you trust.
By ZeroKuhl on Reviewed in the United States on November 2, 2025
Sainsmart TPU is my favorite. This one prints extremely well just like you’d expect from Sainsmart. It is ready to print straight from the package. Used for phone cases and drone parts. I purchased the pink glow tpu. While the color is beautiful, don’t expect much glowing. It fades super fast. Reference photo is 2sec shutter. Most likely just the way red works, so good enough. Happy printing!

Dimensionally, the worst filament I have ever purchased.
By Richard on Reviewed in the United States on December 4, 2022
Color and hardness are spot on what I am looking for. I however can't report on printablity, as dimensionally, this is the worst filament I have ever purchased. It's not at any point that I've measured even close to 1.75 mm. I've unwound probably 30 m off the spool, trying in vain to find a good section of filament. All measurements have been between 1.4 and 1.6 mm, definitely not printable. While I doubt this spool is indicative of SainSmart filament quality in general. I won't be spending any more time or money on SainSmart products finding out, as I have precious little of either to potentially waste. I now, have to source filament with similar properties and color from a different brand, while my project sits on the back burner.
