How 3D Printing Works

When convert the 3D model into an STL file, it digitally slice it into many thin section views

The STL machine creates a thin layer of plastic that is dimensionally accurate in shape and size to each section view

It creates each layer in the proper order and permanently attaches it to the previous layer

Several components of an assembly can be made in place at the same time

Multiple pieces can be created in successive layers to create a moving assembly
