Charles Hull invented 3D printing in 1984 after advancements in inkjet printing. 3D printing works by using CAD software to slice a virtual model into layers and depositing material layer by layer until the final model is complete. There are several types of 3D printing including stereolithography, selective laser melting, and fused deposition modeling. 3D printing offers advantages like less waste, cheap manufacturing, and quick production but also has disadvantages such as weaker parts, rougher surfaces, and potential for misuse.
2. 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.
4. 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.
5. 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.

A prosthetic leg is created with a complex structure that
requires no assembly. This opens the doorway to customised
prosthetic limbs
