What is 3D printing in detail

               What is 3D printing

The 3D printing process builds a three-dimensional object from a computer-aided design model, usually by successively adding material layer by layer, which is why it is also called additive manufacturing.

What is 3d printing and how does it work?
  A 3D printer essentially works by extruding molten plastic through a tiny nozzle that it moves around precisely under computer control. It prints one layer, waits for it to dry, and then prints the next layer on top.

 

What is 3d printing in simple words?                         

3D printing is a way of creating three dimensional (3D) solid objects. 3D printing is done by building up the object layer by layer. Usually, 3D printers use plastic, because it is easier to use and cheaper.

Uses of 3D printing Technology

Bio-printing:  researchers at Cornell University published some of the pioneer work in 3D printing for tissue fabrication, successfully printing hydrogel bio-inks. The work at Cornell was expanded using specialized bioprinters produced by Seraph Robotics, Inc., a university spin-out, which helped to catalyze a global interest in biomedical 3D printing research.

Apparel:  3D printing has entered the world of clothing with fashion designers experimenting with 3D-printed bikinis, shoes, and dresses. In commercial production Nike used 3D printing to prototype and manufacture

Soft sensors and actuators: 3D printing has found its place in soft sensors and actuators manufacturing inspired by 4D printing concept. The majority of the conventional soft sensors and actuators are fabricated using multistep low yield processes entailing manual fabrication
