This is really cool! Don't all the ladder test cases that achieve >~50 simply snap the PETG implements though? So isn't the test capturing the force to snap PETG at that thickness vs. the actual bonds?
- ikawe 2y agoYes, but there is a reproducible difference between when different adhesives break the PETG. He concludes that those adhesives are causing the PETG to become brittle, and you should prefer others which don’t.
- ajb 2y agoYes. There are three types of bond failure: - adhesive failure: the adhesive splits from the substrate - cohesive failure: the split occurs within the adhesive - substrate failure: the split occurs within the substrate. Whichever of these that is weakest limits the maximum strength of the bonded item.
