INTRODUCTION with 3D Printing 3D printing is a modern technology in

which 3 dimensional objects are printed from digital data.

Three dimensional object is created by laying down successive layers of material.

What is 3D Printing ?

3D printing or additive manufacturing is a method of converting a virtual 3D model into a physical object.

The creation of a 3D printed object is achieved using additive processes.

In an additive process a 3D object is created by laying down successive layers of material.

History of 3D Printing

The first 3D printer was created in 1984 by Charles Deckard Hull of 3D Systems Corp.

He named the technique as Stereo lithography and obtained a patent for the technique in 1986.

How 3D Printing Work

A person creates a 3D image of an item using a computer-aided design (CAD) software program.

The CAD information is sent to the printer.

The printer forms the item by Depositing the material in layers.

Current 3D Printing Technologies :- 1

Stereo lithography:- It is an additive manufacturing process using liquid UV-curable photopolymer “resin” and a UV laser to build parts a layer at a time.

Current 3D Printing Technologies :- 2

Fused deposition modeling (FDM):- It is an additive manufacturing which uses hot semi-liquid extrude directly to print objects.

Current 3D Printing Technologies :- 3

Laminated object manufacturing(LOM) :- In this, layers of adhesive-coated paper, plastic or metal laminates are successively glued together and cut to shape with a knife or laser cutter.

Current 3D Printing Technologies :- 4

Selective laser sintering (SLS):- an additive manufacturing technique that uses a high power laser (eg:-, CO2 laser) to fuse small particles of plastic, metal , ceramic or glass powders into a mass that has a desired 3-dimensional shape.

ADVANTAGES

In Medical Field, Surgeons are using 3d

printing machines to print body parts.

3D printing allows artists to create objects

that would be incredibly difficult,costly, or

time intensive using traditional processes.

ADVANTAGES

Product formation is currently the main use of 3D printing technology.

3D Saves Time and Cost: Creating complete models in a single process using 3D printing has

great benefits. This innovative technology has been proven to save companies time,

manpower and money.

Challenges Facing 3D Printing

Intellectual property rights of the 3D Printer users.

Nearly anything can be printed by 3D Printers and this is a troubling prospect if criminals use 3D Printers to create illegal products.

APPLICATIONS

Future Scope

With today's 3D printers, if you lose your TV remote's battery cover you can print a replacement battery cover. With tomorrow's, if you lose your remote, you'll be able to print a new remote.

3D printers are always getting cheaper and better.

There is currently research going on to create 3D printers that could print out organs for people in need of a transplant.

Within a decade, 3D printers will become commonplace in houses.

The benefits of such technology are endless

Conclusion

Relatively New Technology.

No restrictions on industry.

Significant decrease in product development cycle and costs.

Full effects on business and society still not know.

Resistance to change.
