@cyclops_@fosstodon.org @freecad@social.freecad.org There are certainly differences in hardness among TPUs all sold as 95A. I used the clear TPU (unknown brand) someone gave me years ago as they could not get it to print. It is noticeably squishier than the other TPU colours I have. The red in the photo was a softer TPE, but it was very hard to print and layer adhesion was not good enough so I reprinted the bottle seal in the clear TPU which is what I used in the end.

@drfootleg@fosstodon.org @freecad@social.freecad.org this is what I was wondering. I currently have the basf TPU and it's quite hard imho. I haven't tried anything else. Would love to print super soft stuff to make good seals
