3D printer (2)
3D printing works on the principle of a hot nozzle, guided on 3 axis compared to the piece, which heat and mechanically removing a thread of material plastic (ABS or PLA are the most used) by successive layers on a plate. The CAD estdecoupe in 2D print layers model.
The general principle is quite similar to that of a conventional 2D printer
3D printer3D printing is an additive production technique developed for rapid prototyping. Its goal is to quickly and easily generate a physical piece. Different materials can be used, more generally ABS plastic, PLA plastic, and metal, but also wax, or even plaster.
The applications of 3D printing are varied, but in all cases aim to concrete visualization of projects, or verification of parts ergonomics. 3D printing works
CAD (computer aided design), 3D printing from a file allows the user to produce a piece (through software that cut sliced) in filing or solidifying material layer by layer, which allows to get a physical part in 3D.
The printing time, variable depending on the room volume and print speeds, is a few hours.
