History of 3D Printing

The first working 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.

What is 3D Printing? It is a method of converting a virtual

 3D model into a physical object. Where a 3D object is created by laying

down successive layers of material.

Types of Printers? Dot matrix

Ink Jet Laser Lcd

Different methods

1. Selective laser sintering (SLS)

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

Different methods 2. Stereo lithography

Stereo lithography is an additive

manufacturing process using a

vat of liquid UV-curable photopolymer ”resin” and a UV laser to build parts a layer at a time.

Different methods 3.Fused deposition modeling

(FDM):

Fused deposition modeling (FDM) is an additive manufacturing technology commonly used for modeling, prototyping, and production applications.

How it works ? You only need a printer, raw material, and software to tell the printer

what to print.

A virtual design of the object is created.

CAD (Computer Aided Design) uses a 3D modeling program or 3D scanner for virtual design.

Applications

Industry Growth

Will change the nature of commerce, because end users will be able to do much of their own manufacturing rather than engaging in trade to buy products from other people and corporations.

3D printing will change the manufacturing world with effects on energy use, waste reduction, customization, product availability, medicine, art, construction and sciences.

Advantages

Rapid Prototyping: 3D printing gives designers the ability to quickly turn concepts into 3D models or prototypes (a.k.a., rapid prototyping).

Clean process: Wastage of material is negligible.

Complex shape: It can be produced .

Easy to use: No skilled person needed.

Reduce Design: Complexity

Cost: Cheaper process than any other process.

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.
