3D printing is an innovate technology which this creation let you create a lot of shapes in physical basic in this new technology.
The 3D printer work is called additive manufacturing, because unlike the traditional subtractive manufacturing, 3D printing doesn’t remove material, it adds it, layer after layer.
The 3D printers use plastic filaments (1) which are fed into the printer by the feeder (2). The filament is melted in the print head (3) which extrudes the material onto the build plate (4) creating your object layer by layer.
