Kinda had it with ABS. Trying to do large prints and the warping and cracking is driving me nuts, that is if the print doesn’t peel off the build plate and fail altogether in the first place. I’ve done what I can as far as print settings to have the best possibility of success, but even then the prints will often split.
I print car parts and things that are exposed to heat and chemicals occasionally, so ABS has been the easy choice, but are there any filaments out there that have comparable qualities but aren’t as likely to warp?
PETG works great as long as the part doesn’t need to handle more than 60°C. It’s easy to print with and doesn’t warp.
I would not recommend using PETG-CF though. It will shed microscopic fibers unless you coat it in varnish or epoxy.
Didn’t have any issues with deforming of PETG parts in my car. Yeah, -CF should be handled with care, but there are parts that you might not need to touch, and it will be a bit more resistant to deforming under heat.
