Most 3d printed guns are constructed very similarly to “real” commercially available (in burgerland) guns that use a polymer construction. The plastic is taking very little of the force, they use metal inserts and rails that the mechanical parts connect to. This distributes the load a lot. I haven’t printed any yet, mostly because you basically need to buy a whole gun to build one, but they aren’t magic or anything and you could do the same thing with woodworking tools by hand if you had a lot of patience.
The most reliable one I have uses an AR style fire control group, and large metal pieces for the bolt, and pre-hardened hydraulic tubing for the barrel.
There’s plenty of metal in it, all held together via 3d printed parts and frame
The only things I needed to buy that I would consider “from a firearm” or “from a gun store” would be the fire control group. Everything else was bought from McMaster Carr or local hardware stores.
Spot on with the woodworking. I’ve made a couple stocks for my grandfather’s old broken long rifles. It’s just more time consuming. (also my 3d printer isn’t that long)
