French Saboteurs Altering 3D Printed Gun Plans

In this particular video the mold isn't being used to make firearms but the concept is the same.

Oh? Care to share a picture?

Ok, what's the catch? The top half of the part looks alright while the bottom is a melted mass of mixed plastic+metal?

or is that rubber some sort of special ultra thermal resistant compound
sage for doublefagging

It's not plastic, it's 3D printed silicone. The catch is you have to use metal that melts before silicone does.

I'm not really sure of the physics of this but from around 1:05 the dude doesn't seem to have too much of a problem separating the metal from the mold.

Speaking of melting points:
Silicone rubber: 300C
Aluminum: 660C
Iron: 1538C
Steel: 1510C
Lead: 327C

That's why he used that shitty "tin bismuth alloy".

No, you can see the 3d printed mould that he pours the silicone into. The metal he's using is shitty bottom tier aluminum. I actually remember when I was 5 or 6 years old I had a toy oven that did the exact same thing and came with a little mould of a car and other shapes. This metal is NOT gunworthy. You'll get 4 or 5 shots maybe, when you'd get a single shot with a polymer gun…

Pic related. Same exact thing kek

I suppose in which case the kind of metals or alloys that can be used would be limited. Still, a weapon so derived would probably be better than a plastic based weapon in terms of durability I am assuming
