Printable PC/Nylon/ABS are not the same as the injection molded equivalents, you may want to research this more if that is an issue. I've printed every material under the sun trying to chase various material properties, and I usually just come back to printing in PLA due to it's excellent mechanical properties (up to a certain temp), excellent layer adhesion, and near 100% success rate. When you stray from from PLA, you will start running into warping, shrink, layer adhesion, and other issues. If you need parts in PC/Nylon/ABS, get the design dialed in in PLA (I as almost all others recommend bambulab), and then send the part to FirstCut/Protolabs to have it machined out of whatever you want.
