Tweaks for max structural strength with PETG-CF & K1C??

Flagship K Series Creality Flagship K1 & K1C

Hi all,

I’ve got a bracket that will be printed with PETG-CF and would like to know what tweaks I should make in Creality Print to maximize the overall strength of the part. The part is a bracket will hold a small avionics component in an experimental aircraft that is designed for +6 and -4 G’s.

I’m coming from Cura so still getting used to finding parameters in Creality Print that can be changed.

Thanks!

For increase the strength put more walls loops 4 or 5 is good. And use one of the engineering infilling Infill | Creality Wiki For me the Gyroid is the most sturd one.

Thanks.

I’m also wondering about printing speed, fan speed, using a higher temp to improve bonding betwen layers, etc. Does anyone have enough experience with the K1C default PETG-CF settings to weigh in on whether or not there are tweaks worth doing to improve strength?

Yes, increase you walls to 5 and if it were me I’d make the infill solid as in 100%. When I print with PETG I turn off the parts fan for the first 3 layers to get a good foundation then only run the fan at 30% the rest of the print. I always slow down my prints unless I’m prototyping where I’m just checking the design and fit. Print quality isn’t a factor at that point. Good luck.

What aircraft is it going in? I’m an A&P and have worked on a bunch of experimental general aviation aircraft in the past.
