Re: use stainless nozzles for everything?

Heat transfer in stainless steel sucks compared to brass. If trying to print fast, I could imagine a situation where the tip of the nozzle cannot maintain temperature as the plastic passing through it draws out the heat - and transfer through the material can't keep up with the demand. Thermal condu...

Re: Problem in large print

Are those X/Y shifts in the print, or ridges? Looks like shifting to me.

Re: Black ePC - disappointing first print

I print on PEI at 110C. Haven't messed with hair spray or glue with ePC, and I know Kapton didn't work for me. I don't recall what else I tested before getting good parts.

Re: Black ePC - disappointing first print

FWIW I take the temperature ranges as a starting point, but often find I get much better part strength outside their suggested window. These days I print a vase-mode calibration cube and flex the sidewall to see how the layers are bonding. If a part splits with little or no effort or will pull apart...

Re: Black ePC - disappointing first print

I actually haven't run the material again since this original post. I have found, however, that eSun's black PETG gets very brittle when run at higher temps, but is good and tough at lower temps. eSun suggested I run the black ePC at a lower temp, so it might be a similar situation. I am backed up w...

Re: esun epa question

I haven only printed a few test parts with the ePA nylon. A highly-regarded build surface is linen-based phenolic sheet like Garolite LE. I tried PEI and Kapton with no success. I believe glue-stick is used with success with nylon, but I did not test that. The Garolite LE worked very well - almost t...
