This document provides an overview of 3D printing presented by Sundeep Soman. It begins with an outline of topics to be covered, including the history, technologies, applications and success stories of 3D printing. The main technologies discussed are stereolithography (SLA), selective laser sintering (SLS), and fused deposition modeling (FDM). The history outlines key developments such as the invention of stereolithography in 1984 and the introduction of the RepRap project in 2006. Applications highlighted include engineering, architecture, healthcare, jewelry and customization of everyday objects. Overall success stories demonstrate the use of 3D printing in fields such as manufacturing phone cases, aircraft components, and the first ever 3D printed car.

4. WHAT IS 3D PRINTING?
3D + PRINTING = 3D PRINTING

IT IS A RAPID PROTOTPYING TECHNOLOGY-A GROUP OF
TECHNOLOGIES USED TO QUICKLY FABRICATE A SCALE
MODEL OF PHYSICAL PART

IT CREATES PHYSICAL MODELS FROM CAD & OTHER DIGITAL
DATA-LAYER BY LAYER

IT IS WIDELY USED,ESPECIALLY IN PRODUCT DESIGNING

IT REDUCES A LOT OF TIME & COST

IT IS A DEVELOPING TECHNOLOGY

5. HOW 3D PRINTER WORKS?

6. History of 3d Printing
3D Printing was developed by Charles Hull in 1984
Mr. Hull, born May 12, 1939, was an inventor of over 60 U.S. patents in the fields of
ion optics and rapid prototyping.
Mr. Hull’s patent for the “Apparatus for Production of Three-Dimensional Objects by
stereo lithography”, issued on March 11, 1986, defined stereo lithography as a method
and apparatus for making solid objects by successively “printing” thin layers of the
ultraviolet curable material one on top of the other.
After obtaining the patent, In 1986 Mr. Hull founded “3D Systems” and developed
the first commercial 3D Printing machine. However the term “3D Printer” was not
used by that time and the machine was called only as Stereolithography Apparatus
In 1988, 3D Systems delivered its first version of the machine, named SLA-250, to
the public

7. HISTORY CONTINUES
While Stereolithography systems had become popular by the end of 1980s, other similar
technologies such as Fused Deposition Modeling (FDM) and Selective Laser Sintering (SLS) were
introduced.
FDM was invented in 1988 by Scott Crump who founded ”Stratasys” in the next year to
commercialize the technology
In 1993, Massachusetts Institute of Technology (MIT) patented another technology, named “3
Dimensional Printing techniques” (3DP), which is similar to the inkjet technology used in 2D printers
In 1995, Z Corporation obtained an exclusive license from MIT to use the technology and started
developing 3D Printers based on 3DP technology
In 1996, three major products, “Genisys” from Stratasys, “Actua 2100″ from 3D Systems and
“Z402″ from Z Corporation, were introduced. It was only during this period, the term “3D Printer”
was first used to refer rapid prototyping machines
In 2005, the Spectrum Z510, was the first high definition color 3D Printer in the market, launched.

8. HISTORY CONTINUES
In 2006, a breakthrough open source printing project, named “Reprap”, was
developed in England. The rep-rap was capable of manufacturing various plastic
parts, roughly 50% of itself
In 2008, the first version of the Reprap, the “Darwin”, was released. In continued
development of Reprap printers the next model developed was the “Mendel”
In 2010 the first 3D printer was introduced that could produce functional
prototype parts

10. 3D PRINTING TECHNOLOGIES
Stereo Lithography Apparatus (SLA)
Selective laser Sintering (SLS)
Fused Deposition Modeling (FDM)

11. Stereo Lithography Apparatus
(SLA)
 The first Rapid Prototyping technique and still the most widely used
Inexpensive compared to other techniques
Uses a light-sensitive liquid polymer
 Requires post-curing since laser is not of high enough power to completely cure
 Long-term curing can lead to warping
Parts are quite brittle and have a tacky surface
Support structures are typically required

14. Selective laser Sintering
(SLS)
Patented in 1989
Considerably stronger than SLA; sometimes structurally functional parts are possible
Laser beam selectively fuses powder materials: nylon, elastomer, and metal
Advantage over SLA: Variety of materials and ability to approximate common engineering
plastic materials
SLS creates accurate and durable parts but finish out of machine is relatively poor

17. Fused Deposition Modeling
(FDM)
Standard engineering thermoplastics, such as ABS, can be used to produce
structurally functional models
Filament of heated thermoplastic polymer is squeezed out like toothpaste
from a tube
 Thermoplastic is cooled rapidly since the platform is maintained at a
lower temperature
Make rapid progress in past few years and be used widely
