FDM using TPU 95A

[Hinns 0]

What are the possible challenges when FDM is performed using TPU 95A as the filament in Ultimaker 2.0 + 3D Printer ?

TPU-95A by nature oozes a little bit more than other filaments, so depending on your project and how bothered you are by it you may need to tweak some settings in your print profile. It has a different profile than other materials, but that goes for every material, they are all different. TPU-95A is generally a little bit slower I believe, due to its flexibility. Because Ultimaker does not use direct drive, there is a limit to the flexibility of filaments it can handle, but TPU-95A is well within its range. Hope this helps!

Do you have any recommendations on which settings to change?

Thanks,

I print Ninjaflex, Cheetah and armadillo, Ninjaflex is the most flexible, like rubber, where Cheetah is slightly more ridgid.

 

I print them on an ender 6 which has a bowden style, not direct drive, the best way to reduce the stringing may not be retraction as you might jam the filament, it'll stretch inside the bowden tube rather than pull it back if it's flexible.

 

I find figuring out what settings reduce travel helps the most, which depends on the model, but if you use Cura you can see the moves, which is exactly where the stringing will be, but generally, I just trim it when it's done.

 

Hope that helps.
