Nylon in from Printrbot for the TR6 bushings. Suggestions for print temps/settings? I don’t have a heated bed.
I like UHU gluestick and low layer heights for nylon. Printing nylon fast with low layer heights helps reduce warping (for complicated reasons that aren’t worth getting into unless you’re interested).
By low layer heights do you mean low res like a .3 or .1 low as in thin?
Thin layers.
@Ashley_Webster nylon strain-crystallizes like nothing else. It has totally different material properties when it’s stretched out and crystallized vs amorphous. When you print hot and slow and with big strands, the molecules all relax to a tangled state in the melt and it cools amorphous. When you print fast and thin layers, the molecules get sheared leaving the nozzle and that helps align them to a more crystalline state. Notably, this makes it stiffer and lower thermal contraction along the longitudinal axis of the strands. So it’s lower warp when printed that way.
So what speeds would you recommend @Ryan_Carlyle ? I’m thinking 45mm/s at 250c and .1mm layer height.
I try to stay over 80mm/s but of course acceleration slows you down on detail. Even just having the long, straight lines contract less really helps with warping.
Around 230, give or take
