What is 3D Printing?
- 3D printing or additive manufacturing is a manufacturing technique . It involves
- making three dimensional objects
- from a digital design
- by adding one layer at a time.
- Architecture and Construction – Countries around the world are using large 3D printers to construct multi-storied houses layer by layer.
- Medicine – Bio printing of artificial organs like Liver, Pancreas etc
- Manufacturing – Car and aeroplane parts are being built using 3D printing.
- Repairing Damaged Cultural Sites : Eg Allepo in Syria is being re-created after ISIS destruction using this technology
- Prototypes : Prototypes can be made very cheaply
Any object can be made. Just make digital design in PC , add material in the 3D Printer and it will make it
- No Wastage : 3 D printing is additive process , in which object is manufactured by adding layers in contrast to present manufacturing techniques which are reduction processes . Hence, there will be no wastage of material and cost of production will reduce dramatically
- Manufacturing Decentralisation : In contrast to centralisation ie making products in centralised manufacturing units, it will usher revolution of decentralised manufacturing , creating business opportunities
- Customised Products : Presently companies make standard products because mould they use is same. But using 3 D Printing, customised products according to need of person can be made without any increase in cost of production
- Breaking manufacturing Boundaries : Using 3D printing, we can manufacture things which were impossible to manufacture using ordinary manufacturing techniques . Eg Body Organs etc
- Saves Time – 3D does the job accurately and in less time.
- Job Losses : Single 3 D printer can make products which was earlier made by hundreds of workers
- Security challenge : Even weapons can be made at home
