17. 3D Printing
What is 3D printing and how does it work?
3D printing or additive manufacturing is a process
of making three-dimensional solid objects from a
digital file. The creation of a 3D-printed object is
achieved using additive processes. In an additive
process, an object is created by laying down
successive layers of material until the entire object
is created. Each of these layers can be seen as a
thinly sliced horizontal cross-section of the
eventual object.
It starts with making a virtual design of the object
that is to be created. This virtual design is made in
a CAD (Computer Aided Design) file using a 3D-
modeling program (for the creation of a totally
new object) or with the use of a 3D scanner (to
copy an existing object). A 3D scanner makes a 3D
digital copy of an object.
