The NYLON 645 i had orderd by igo3d.com
I had canceld in the moment the test with nylon. (need the time for other things in the moment)
So i had no parameters at the time. By the first test (with the gear) the kapton and the blue tabe will warp. (the nylon sticks at he tapes and pull the tapes up from the bed)
so i think 90°C was to mutch heat on the bed. (after i had senn thad the glasstemp. is at 68°C, i will do tests in the future with 75°C)
The print temperature was 245°C and the layer binding is great.
The nylon is a elastic material. by 1mm wall thiknes you can deform the printed objects like a rubberduck in your hand.
And yes i used the original nozzle.
the gear i printet with nylon is not so flexible like the 1mm wall. (and i had made only 2 test prints with nylon)
but i think it is very strong in heavy duty.
