That can work, but 3d printing doesn't in general make for strong parts (layers). Most of the time you want some form of molding or CNC subtractive machining (either plastic of metal) - while some hobbyists have this, 3d printing is far more common. (and often easier)
FDM in PLA/PETG sure, although recent advances have improved on this via things like brick layers.
Resin based printers are a whole different story though. They can make really durable parts. And even FDM with more advanced filaments have gotten competitive.
