3D printing uses molten deposition modeling to extrude plastic layer by layer based on a 3D design file. 3D designs can be created using computer-assisted modeling software or 3D scanners, and involve shaping geometric data similarly to sculpting. While early 3D printers were large, expensive and limited, additive processes have advanced to include industrial applications as well as domestic, hobbyist, fashion, eyewear, bio-printing and medical implant uses.

2. What is 3D printing
The term 3D printing originally described a process using conventional and
custom-made inkjet print heads. The modern technology used by the
majority of so-called 3D printers to this day especially hobbyist and
consumer-oriented designs is molten deposition modeling, an unique
application of plastic extrusion.

3. 3D printable models
3D designs could be created with a computer assisted style package deal or
by means of 3D scanner. The hands-on modelling procedure of readying
geometric data for 3D computer system graphics is similar to plastic fine
arts such as shaping.

4. Additive processes
A number of various 3D printing procedures have
actually been invented given that the late 1970s. The
printers were initially big, costly, and very restricted
in what they could possibly create.
