What is 3D printer? How does 3D printer work? What is the use of 3D printer?

3D printer

A 3D printer is a device which creates a three-dimensional object or a prototype of an object. 3D printer is a computer aided manufacturing(CAM) device. It creates the product from software created 3D  designs, diagrams, figures and patterns. It directly build the end product. It The process used by 3D printers is called additive manufacturing. It forms the object layer by layer until the model is complete.

3D printer working process

3D printer uses digital data as an input and builds a three dimensional object as an output. 3D working process starts with making a virtual design of an object. This virtual design can be created by using 3D modeling program in a CAD(Computer Aided Design) file or with the use of a 3D scanner(which makes a 3D digital copy of the object). Then the 3D printer builds the object from bottom to top, layer by layer.

Uses of 3D printers

3D printers are used in various areas. Automobile, aviation, medical, construction and various other fields use 3D printers. Some use of 3d printers are as follows:
  • spare parts of car
  • jigs and fixtures of manufacturing industry
  • aviation industry
  • making different components of a building
  • reconstructing bones and body parts in forensic pathology
  • rapid prototyping
  • furniture design

Advantages of 3D printing

Some advantages of 3D printing compared to conventional process are as follows:
  • few human resource requirements
  • no special tooling required
  • possible to reconstruct the damaged sections of existing objects
  • high speed manufacturing
  • easy to manufacture complex parts
  • a wide range of use
