CONCLUSION

PRINTING

Printing is a process for reproducing text and images.

DEVICE USED –PRINTER

Types Of Printers Dot matrix Ink Jet Laser Lcd

HISTORY OF PRINTING

In 1953 The first high-speed printer was developed by Remington-Rand .

In 1964 The first dot matrix printer was marketed by IBM.

Later laser (1969) and inkjet printers (1976) came into being.

Now it’s the period of 3D PRINTERS.

3D PRINTING

It is a method of converting a virtual 3D model into a physical object.

Additive Manufacturing Technology where a 3D object is created by laying down successive layers of material

Rapid Prototyping Technology i.e Objects are created using three dimensional files using software CAD and a device called 3D printers.

3D PRINTERS

3D printers allow designers to quickly create prototypes of their designs, rather than just two-dimensional pictures.

URBEE

2010 Urbee the first prototype car was presented. This is the first car ever to have its entire body printed out on a giant 3D printer.

It has three wheels, and two seats.

3D CHOCOLATE PRINTER

In Jul, 2011

Led by the University of Exeter, The University of Brunel and application developer Delcam,researchers in UK have presented the world's first 3D chocolate printer.

WORKING

You only need a printer, raw material, and software to tell the printer what to print.

STEP 1 (CAD FILE IS CREATED)

STEP 2

The CAD file is exported to a 3D printing machine.

LAYER BY LAYER

STEP 3-ACTUAL OBJECT

TYPES OF 3D PRINTING TECHNOLOGIES

There are four different processes that are all referred to as “3D printing.

Their main differences are found in the way layers are built to create parts.

Selective laser sintering (SLS) Inkjet

Fused Deposition Modeling (FDM)Stereo lithography (SL)

APPLICATIONS

AREAS OF APPLICATION OF 3D PRINTERS

Industrial design Automotive and aviation industries Architecture FOOD INDUSTRY Medical Industries Jewelry Footwear Engineering and construction

INDUSTRIAL DESIGN

Designers use 3D printers to quickly create product models and prototypes.

AUTOMOTIVE AND AVIATION INDUSTRIES

Automotive and aviation industries use 3D printers to make body parts.

ARCHITECTURE

Artists can create models of their projects.

FOOD PREPARATION

In food preparation, to apply items in liquid or paste form such as cheese, icing, and chocolate.

MEDICAL INDUSTRY

Physicians can use 3D printing to make hearing aids, artificial teeth, and bone grafts.

OBJECTS MADE WITH 3D PRINTERS

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 can be produced .

EASY TO USE No skilled person needed.

CHEAP Cheaper process than any other process.

Allow more design iterations to choose from.

People in remote locations can fabricate objects that would otherwise be inaccessible to them.

DISADVANTAGES

Process is slow

Components do not have enough strength.

3-D printers are still expensive.

Although 3-D printers have the potential of creating many jobs and opportunities, they might also put certain jobs at risk .

(for example, you can make your toys at home so toy stores and toy makers might go out of business).

CHALLENGES

• Nearly anything can be printed by 3D Printers and this is a troubling prospect if criminals use 3D Printers to create illegal products. 3D printing has a lot of possible benefits to society, although the products created must be regulated.

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.

CONCLUSION

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

The benefits of such technology are endless.

It will become a “FACTORY ON YOUR DESK”.
