3. Introduction
 3D printing is a form of additive manufacturing technology where a
three dimensional object is created by laying down successive layers
of material.
 It is also known as ADDITIVE MANUFACTURING.
 3d Printing is a achieved using an additive process, where successive
layers of material are laid down in different shapes.

4. History
 The technology for printing physical 3D objects from digital data was first introduced
by Charles Hull in 1984.
 He named this technique as Stereo lithography and obtained a patent from this
technique in 1986.
 In 1993, Massachusetts Institute of Technology (MIT) patented another technology,
named “3 Dimensional Printing techniques”. Which is similar to the Inject technology
used in 3D Printers.
 In 2006 Z Corp, Launched a breakthrough product, named Spectrum Z510, which was
the first high definition colour 3D Printer in the market.

5. Terminology
 Additive Manufacturing:- It is defined as the process of joining materials to
make objects from 3D model data, usually layer upon layer, as opposed to
subtractive manufacturing methodologies
 Rapid Prototyping:- Group of techniques used to quickly fabricate a scale model
of a physical part or assembly using three dimensional computer aided design (CAD)
data.
 Subtractive Processes:- Removal of material by methods such as cutting or
drilling.

11. Latest Technologies in 3D Printing
 Australian manufacturer Aurora Labs have been developing a 3D printer
which prints the metal parts at a speed of 3 Ton metal per day
 MELD Manufacturing Corporation has developed a new way to 3D print
metals without melting the material. Tis technology has been in development
over a decade, was first unveiled last year with the introduction of MELD B8
machine.
 HP’s Metal Jet, it enables the new technology in the 3D metal printing called
Binder Jetting

12. Applications
 Design Visualization of Engineering Components.
 In Bio-Medical models like prosthetic arms, human skull.
 Electronic Modules Like Speakers, Television components,
Computer components etc..,
 In Fashion technology, used to manufacture jewellery, foot
wares etc..,
 In Archaeology, used to reconstruct the sculptures,
monuments etc..,
 In Automobile industry for conceptual design of cars,
bikes, other components.
 Aerospace industry for manufacturing aero engine with
metal alloy.
 Testing of newly designed parts in industry.
