3D Printing in Manufacturing Sector

Did you know that complex plastic or metal parts can be built in a few hours using 3D printers for manufacturing sector, and military purposes?


3D printing is also known as additive manufacturing. This technology uses a digital/CAD design to create three dimensional objects. The manufacturing process generally involves adding up of multiple thinly sliced cross-sections of the object (additive process). This ‘additive manufacturing’ process is an exact
opposite of regular/subtractive manufacturing, where parts are created by drilling/boring out
excess material from a block of metal or plastic.


In 1967, the first patent for a 3D printer was filed by Wyn Kelly Swainson of Denmark, called ‘method of producing a three-dimensional figure by holography’. He also filed two relevant patents on 3D printing in 1971 and 1977.
