Dialing in Prusament PC Blend on a Core One
I have a big project coming up and bought several rolls of Prusament PC Blend. First thing I did was print out a Benchy with the Prusament PC Blend profile 0.4mm Diamondback, 0.20 STRUCTURAL. Prusa set the max flow rate to 12 mm^3/s which is probably a tad conservative. Before I waste a bunch of (expensive) filament trying to dial-in a faster setting has anyone does this yet? Otherwise I guess I can fire up OrcaSlicer and run the volumetric flow test.
Anyway, this filament is really nice. Best Benchy out of all my filaments.

At least in my case, the 0.18% X,Y,Z shrinkage compensation was slightly too small. I calibrated it to 0.75%

So what type of part are you making?

Actually now it's two projects. The first is a fin assembly (and possibly nose cone) for a model rocket, the second is long spars for the INBXX - for PRUSA INDX in preparation for when I receive my INDX kit. In both cases I need dimensionally accurate parts and PC can be tricky if it's not correctly dialed-in.

What is interesting for the rocket parts is I was originally using PC-CF and PA-CF under the (now naive) impression that they would be stronger than the "blended" PC and PA filaments. They are certainly much easier to print than PC or PA and don't warp (as much). But the chopped carbon fibers actually make the parts weaker and less impact resistant.

I just had a nephew build and fly a Gen 2 rocket. Not sure how he made the rocket. Don't think he printed it.

For the RC model planes, they recommend the LW-PLA. The first plane I made was just in the PLA. I didn't finish my plane in the LW-PLA.
The big issue is that they have trouble with warping in the sun. So I probably should switch to a higher temperature filament.
RE: Dialing in Prusament PC Blend on a Core One
For something like a plane or drone I would think some sort of ASA filament would also be a good choice. Especially given that it's UV resistant. PC filaments would also be an excellent choice if you can control the warping. PC-CF is an exception but it's even more expensive than PC Blend. Probably a good compromise would be a combination of LW-PLA and PC-CF.

Like the Estes kits that were around when I was a kid (and are still around) the beginners tubes are usually phenolic cardboard. For the Level 1 and 2 rockets (the big boy versions) there are kits available and the tubes are typically fiberglass, carbon fiber epoxy or phenolic resin. If printing your own then generally PA-CF or PP seems to be the better choice. When you get to Level 3 then 3D printed rockets have a tendency to fall apart (literally). I'm not there yet but plan on getting there eventually.

Another fun fact that I forgot about... Black PC Blend warps more than Orange PC Blend given that black will have different thermal properties than orange. Printing the same part with black PC requires a brim whereas I don't need one with orange.
