Qidi makes decent printers, far as I know they are not a print shop as well. If you have technical issues call Qidi, if you need help with print settings and such your better off asking other makers on forums like this.
I run most PLA prints with the cooling at 100% from layer 2 on. It really helps the material set in place fast where it should be.
Honestly I don't use PLA unless its something that NEEDS to be PLA to come out right. 90% of my machines runtime it's printing ABS.
For something like a prosthetic knee (or anything else for that matter) your gonna want more rigidity and impact tolerance than PLA will provide. For this you wanna look at higher grade ABS, or some nylon, though I don't think you can print that with stock setup.
