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.
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
AUTOMOTIVE AND AVIATION INDUSTRIES
Automotive and aviation industries use 3D printers to make body parts.
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.
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”.
