I am new to 3D printing. Just started couple of months ago and currently have been experimenting with different materials. (ABS,PLA,Nylon,TPU)
With most of the materials I have understood the basics and the prints are quite good (for a beginner, as I have been told), however with TPU I have yet to fully understand its specifics.
Below is a image of TPU print (not finished) and it seems to look like under extrusion.
The following settings were applied:
L/H - 0.2mm
Infill - 50%
Print Speed - 30mm/s
T/B - 15mm/s
Travel Speed - 120mm/s
Material flow - 145%
Fan Speed - 50%
Temp. - 230C
Bed temp. - 70C
Am I correct to assume, that this could be the case of under extrusion? If so, what would be the possible solutions for this matter?
Thank you already in advance!
