Ultimaker 3 Extended TPU Print

[curious aardvark]

although, it seems odd that the bottoms look okay.

How many solid shells do you have on the bottom of the print ?
It might be when the infill starts to kick in and that usually prints faster on multiple prints than on a single print - actually most layers tend to.

Hmm, odd.

Hi!Thank you for your replies, i tried your idea last night.It did improve the quality to do it slower, but it is still not perfect. So I believe if i reduce the speed further, it might help with the quality. I agree that is seems odd the print gets worse over time. i believe it can have something to do with how well the material sticks together, and when it gets more time to do this it works better.There is 7-8 layers in the bottom on the print.I hope when i reduce time further, it will improve more as well!
