Adhesive for TPU to PETG
I am working on a project that requires some TPU parts and I need to glue them to PETG parts. I have tried both superglue and polyurethane so far with little success. In both cases, the TPU separated from the PETG. Adhesive stuck to the PETG, not the TPU. I do need a decent bond.
Searches on the web have not lead to any success.
RE: Adhesive for TPU to PETG
I have successfully printed PETG on TPU with a simple color change in PrusaSlicer and increasing the nozzle (not the bed!) temperature up to PETG level. No adhesives at all. Both parts have a solid bond. I used SainSmart TPU 95/A Black and Amazon Basic Clear PETG (because that was just loaded in the dryer for another print).
It was this model: https://www.printables.com/model/914645-sennheiser-rs-185-hdr-185-headband
I posted a make there that I still use today, more than a year later, and print still looks like in the photo there.
