This is my first time printing with TPU after modding my machine to Direct Drive, I’m wondering if this finish is to be expected with TPU or should it be smoother.
I’ll have to give a temp tower a try, these were the first two things I printed after the direct drive mod.
They were more of a test to see if the new extruder setup worked since i couldn’t get it to print with the the bowden setup.
Those reprints look much better! Much more dialed in it seems. I’ve never been able to fully get rid of the stringing with TPU.
Are you running lower temps and speeds now?
From the temp tower I would probably stick to the 200C +/-5C for your spool (as long as there is no clogging or skipping). It looks like that spool loses detail and finish at temps >215C to me, but test and tune yourself for sure!
I love seeing others use TPU and TPE, a doorstop seems like a good use case. I’m finding all sorts of odd uses for it nowadays.
I printed a belt that i use everyday, so far its been going on 6+ months and no issues. I have also printed a bunch of fidget cubes which are fun. O havent tried it yet but saw a tpu printed flex coupler for a leadscrew on thibgiverse.
Though its not house branded, (sainsmart i think) and ive just been useing the stock prisa mini settings for my prints. I did have to free up each link, but didnt have too much stringing on it externally.
