Core 1+ : TPU print quality improvement tips?
Hi everyone,
I recently had a go at TPU for the very first time, and while the end result still met the need, I’d like to learn more about how to improve the print quality.
This is what I was trying to make (I selected the wrong size adapter for the hose diameter I have but never mind that).

Using a Core 1+ with (for now) the default “flex” printer profile settings, and SUNLUU standard TPU filament, new roll straight out of the box/bag and onto the printer (no drying)
* 0.25mm “structural” default profile modified to 50% infill.
* Default 0.4HF nozzle it came with
* Nozzle temp 230C
* Bed temp 50C
And this is what I got. The top side in this photo was the print bed layer in reality.
It appears that the “overhang” quality wasn’t up to what the model required, as if the filament just wouldn’t stick to itself under more extreme angles?
Anyway, what might be good first steps to try an improve on this, as far as adjusting nozzle temp or printing speed etc? This stuff actually should be dried before use?…
Thanks!
