Hi All,

I love the idea of this filament, and I know it is experimental, but I'm not finding it very useful. The filament prints fine on an unheated bed (blue tape only). We have tried printing a small cylinder 1" in diameter and 0.75" tall (2 shells using a 0.5mm nozzle). We printed four from the same gcode, the only thing modified between the four printed was nozzle temp. We ran 215, 220, 225, and 230. All printed without any issues. We left all four cylinders submerged in clean room temperature tap water for 4 days, changing the water every day. Unfortunately the results were not good, to sum up:
- flexibility in the z-plane is roughly similar to TPE (about shore 87A)
- delamination happens with very little force and results in a stringy membrane between printed layers

We have let them dry out. They return to the mechanical properties they had before submerged in water.

We did not try to paint or dye the samples.

Different experiences? I really, really wanted this to work! TPE and TPU filaments rocking shore 80A's are waaaay too stiff for what we are doing. We need to get to a shore 10 (dreaming, I know ).

Thanks
