RE: PETG and TPU, sticky?

We designed a smartphone cover with TPU seals (Sainsmart) and PETG for the hard parts (some cheap one, idk anymore).

It sticks quite well using 260 °C. In addition to that I made a geometrical lock design - even if it would have become loose, you could not pull it out because the seals are locked in the hardcases. This is the seal:

So I suggest higher temperatures and design-change for a geometrical lock if possible.

RE: PETG and TPU, sticky?

I also do a smartphone cover that's mostly TPU but I do the last 3mm in PET. It's been very durable so far. I've found the TPU you choose matters. 98A Flilamentum prints really nice at 240 so it's hot enough the PET will print and then I tune to 250 as soon as the print resumes. Works a treat. What temps are you using when you see separation?
