Not very likely. USBc-PD is 20v/5a . Most printers are either 12 or 24 volt rails, at 40 or more watts of power for the hotnend alone, toss in the stepper motors, the fans, the board running and you're very close to going anemic on the power supply.
You probably could get away with a resin printer, though, that doesn't have the massive hot end. Some kind of transparent LCD (laptop screen disassembled? or maybe the old school kindle e-reader LCD's) and UV led strips/arrays under it should be fairly easy to build and run.
Latest pd spec can do up to 240w at up to 48v (good luck finding a power brick that supports the full spec, though)
