I had a nylon print done on a cylinder shape thats about a half inch thick. The nylon sleeve slides over an aluminum core, but the nylon layers delaminates on impact. I don’t have this problem with abs plastic. Is it possible to get the same adhesion as abs or is this one of the drawbacks to nylon?
My understanding is to get the best layer adhesion the layer being printed on needs to be hot. When I print with my nylon I have to make sure I’m close to this average temperature sweet spot where the layer being printed on is still hot enough to accept the molten bead.
Ive always heard you have to print slow, and hot. Wouldn’t it make more sense to print fast in order to have the new filament bond to the hot already extruded layer?
This is the best instruction I’ve seen. 3D printer improvements: How to 3D print nylon and trimmer line reliably: do not dry it too much and glue your bed! 63
“So even more than with other material, the faster you print Nylon, the higher the temperature you need. The symptom is that Nylon still flows correctly, but it does not have enough time to bond to the previously deposited material. The layers then cracks open as soon as you bend the object.”
Try high feedrate, low acceleration, high jerk. Try to get the outflow as constant as possible by reducing retraction setting. I almost have no stringing because my travel is very fast.
