Important to note: 3D PRINTED FIREARMS DO NOT BREAK WITH A FEW USES
Firsthand knowledge.
200-250 rounds and still going strong, inspected before and after firing every time
No damage so far.
Beyond that point, I agree with everything posted.
I think that highly depends on your knowledge about 3D printing an what materials you use.
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.
Ah, that makes sense.
