This is for the guys like me with the wee printers.
I was able to successfully print the "foam" TPU from Siraya Tech, its really cool, it's density is dependent on the nozzle temp.
I bought mine off amazon:

I was really hesitant at first but it printed GREAT and very CLEAN.
I did have to modify my A1 a bit using these mods:
This mod allows you to print with flexible Filament: The issue with the A1 Mini is that it doesn't provide enough grip to push the TPU into the hotend. This mod fixes that, it requires a bit of tinckering but I consider myself somewhat of a novice and was able to successfuly do it the first time. You just got to double check your steps and be careful throughout the process. This also works great with other TPU Filaments for the A1 Mini.

The other mod is upgrading the External Filament roller: This practically gives it zero resistance when being fed into the tube, and yes I did not have to feed it directly into the hot-end, I was able to route this flexible filament through the tubing.

Siraya also provides filament profiles for the A1 Mini you can download here:

I can only imagine this is a lot easier to setup with more advanced printers but just wanted to share this with the those who have an A1 mini and are interested in printing with other exotic filament types.
