What is 3D Printing

Imagination rules the world! In everyday life we often say-- I wish this car had same seats like my old car, I wish I could give veggies to my child in the form of fast food, I wish I could design a jewellery same as the lost one. 
Now you could create your imagination, not by any magic lamp but with the help of 3D printing. 

3D printers, after many trials and research, are now available to print out your ideas.  It provides fast, reliable and repeatable manufacturing with maximum utilization of raw materials.

In the process, an object is scanned or designed with Computer Aided Design software(CAD), then sliced up into thin layers, then printed out to form a solid three-dimensional product. 

'If the last industrial revolution brought us mass production and the advent of economies of scale - the digital 3D printing revolution could bring mass manufacturing back a full circle - to an era of mass personalization, and a return to individual craftsmanship'. (Andreas Gebharat, Fachhochschule Aachen).

Some of the common 3D printing technologies are Stereolithography( SLA), Fused deposition modelling (FDM), Selective laser sintering ( SLS) and Multijet modelling ( MJM). 

Some of the major applications of 3D printing are:

Medical applications

From implanting beak to an eagle to making human body parts, 3D printing is successfully working in the medical field. Now a doctor could even customize doses according to the patient's requirement. In Brazil, a team of doctors successfully printed the silicon prosthesis of a man's face, which was ingested by cancer. 

Virtual planning of surgery, personalized instruments, total joint replacement are some example which uses 3D printing in the medical field.

Food industry

Our appetite increases when the food served is great in colour and texture. 3D printing is now being adopted by many food professionals to create unique food items with attractive colour, texture and shape. 

Further, you may encounter a machine which will give you nutrition rich food with your calorie and vitamin requirements. A patient starving for junk food or a child with tantrums could be given nutrient loaded pizza with normal appearance. 

Fun, fashion and entertainment

3D printed eyewear, jewellery, personalized gifts, moulded chocolates are some of the interesting applications of 3D printing. In Japan, there are 3D photo booths with a 48 camera set up to capture you from all angles and create a mini you. 
 
The automobile industry is already improving in this field. Urbee was the first car to use 3D. In future, a fully 3D printed car could come in the market. Construction is being done using 3D fabrication; some have even created complete 3D buildings. 

In future 3D printing could also be used for recycling plastics. 3D printing enthusiasts like Trimatis LLC has shown interest in turning plastic waste into 3D printer filament.
