Warping with Nylon (PA12) CF-15 Filament
I am trying to get my Nylon CF15 prints to work, but I just cannot get rid of the warping. I read that especially the fibre reinforced PA12 is supposed to be less warping due to the high stiffness of the reinforcing carbon fibres. In order to find settings, where I dont get too much warping, I am printing cuboid structures with 20*40*2. So nothing too crazy. I am using a PEI print bed, which provedes pretty good adhesion to the PA12, since I really struggle to get single layers off the bed. But after a few layer, it lifts, no matter what I do. I tried different Nozzle (230 °C - 260°C) and bed temperatures (30 °C - 90°C), different layer hights (0,1mm - 0,3mm) (using 0,6mm steel nozzle), different print speeds and even different cooling (no cooling, or different fan speeds). I also tried 3d-lack and a glue stick, which is for PP pringts. The warpig just allways wins. I dont have an enclosure though.
Is there anybody, that got the PA12 CF15 prints to work? Any advices? I am using Filamentum Nylon CF Filament. Maybe others might work better?
