Sunlu pa6 cf too brittle?
Anyone else having issues with sunlu cf nylon being too brittle? I had a crack form at my rear rail pin. I drilled it out with a 3mm bit, haven't had a failure here in years. Reason I ask is ive printed this project out of their gf nylon and it worked great. May switch back. Printed at stock settings for generic pa cf on a h2c. May try bumping temps to 300 and drilling out with a 3.2mm bit next time or use a reamer.
If that fails il go back to pagf
Edit* dried this at 85 c for 48 hours before printing as well. Let sit in humid air for a couple weeks (it's super humid here, like 70 to 100 percent recently) Print looked solid, not impressed with layer adhesion.
