I do not know what kind of 3D printer you have, so some of this may be a moot point.
If this is your first foray into 3D printing with CF (carbon fiber), you need to consider;
1) Make sure your print bed can heat to 110C (230F) and you are using a satin print plate. A PEI plate will be destroyed by CF.
2) Make sure you use a hardened steel nozzle as CF is highly abrasive and any wear on the nozzle is bad news.
3) If your printer does not have an enclosure, you will need to acquire one.
4) Your nozzle temperature needs to reach to 290C (554F). Most 3D printers can, but check that.
After you print, you will need to anneal the part. Use any old oven capable of sustaining 60C (140F) and leave it in there for about 3 hours and allow it to cool slowly.
As a suggestion, as CF is a pretty expensive filament and slow to print, you might want to print your parts in PLA first and test fit them for dimensional accuracy. Keep in mind, some CF filaments will shrink after printing. Prusa has a PC+CF filament which is more stable.

Once you get the hang of designing parts, you will be surprised how much you use that printer. I got mine earlier this year and already have over 31 days print time. I have chewed through 3.4km (2.1 miles) of filament printing 42 projects to date, with 93 sub parts.
