I have a 3D object that I print with 0.6 mm nozzle and white PETG. At the moment I can't print the layers in another direction since I use 3D printed threads. The object is a de-seeder bit for the sorrel fruit. Some of the teeth break off when using it (see red arrow showing the missing tooth that breaks off when used below).
If you want to see how it's used, I have provided an animation/video of it.
I was wondering if there was a way to increase the strength of the teeth on the bits from breaking. I was thinking of using some type of nail hardener but was wondering if that would work or if I should try and use something else.
I'm also willing to try a different 3D material but it needs to be able to withstand summer heat in Florida in a garage which gets to be 97 °F or 36.11 °C and be printed with an E3D Revo 6 nozzle (which is like a hardened steel nozzle). PLA will just melt/turn rubbery.
