I have a functional part I'm working on that'll be made using ~90A Shore TPU and it needs threaded inserts so I can connect it to other stuff with a screw.

I was planning on doing heated inserts post-production, but I recently read online that TPU doesn't work with heated inserts.

Does anyone have any advice on how true this is, but if so, then what are the strongest alternatives to heated inserts for TPU so I can have as strong or tear-out resistant of a connection for my part as I can?

Thank you!

You would have to put the inserts in from the opposite side, so then more material to pull through.
It is correct to say it's not great, but depends on how much strength you need
