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

HOW 3D PRINTER WORKS?

History of 3d Printing3D 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

HISTORY CONTINUESWhile 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.

HISTORY CONTINUESIn 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

3D PRINTING TECHNOLOGIES

Stereo Lithography Apparatus (SLA)

Selective laser Sintering (SLS)

Fused Deposition Modeling (FDM)

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

ARCHITECTURE

S-L-A PRINTED PRODUCTS

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

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

CONCLUSION

NOTHING COMMUNICATES DESIGN IDEAS FASTER THAN A THREE-DIMENSIONAL PART OR MODEL. WITH A 3D PRINTER YOU CAN BRING CAD FILES AND DESIGN IDEAS TO LIFE – RIGHT FROM YOUR DESKTOP. TEST FORM, FIT AND FUNCTION – AND AS MANY DESIGN ITERATIONS AS YOU LIKE – WITH FUNCTIONAL PARTS.
