HISTROY
3D printing was invented in the year 1984 by Charles Hull with the
advancements in printing methods after the invention of inkjet
printers in the year 1976.

Charles Hull is the co-founder, executive vice president and chief
technology officer of 3D systems.
FIRST 3D PRINTER
PROCESS OF PRINTING
ADDITIVE MANUFACTURING
Additive manufacturing takes virtual blueprints
from CAD and "slices" them into digital crosssections for the machine to successively use as a
guideline for printing.

Depending on the machine used, material or a
binding material is deposited on platform until
material layering is complete and the final 3D
model has been printed.
TYPES OF ADDITIVE MANUFACTURING
1.STEREOLITHOGRAPHY
The process in which this 3D printing is done is stereolithography
which starts with the generation of stl file using CAD software.
2.SELECTIVE LASER MELTING
3.FUSED DEPOSITION MODELING
