Best thing about technology is that it is ever evolving. A groundbreaking technology which was introduced some ten years ago might just look completely obsolete and old today. 3D printers are the brain child of this technological evolution. Although this technology has been around for quite a few years now, it is gaining momentum in the present day as it is moving closer to home usage than just professional usage. 3D printing technology however still needs to run a long race to replace mass manufacturing needs.

Boosting additive manufacturing: 3D printing helps formulate single layer for three dimensional solid objects at the same time by virtually giving any required shape using digital data technology. Most of the manufacturing units have started adopting this technology for efficient functioning. These 3D printers run 24X7, requiring just an occasional visit from the supervisor who only needs to top them up with powered material called ‘ink’ or to keep aside the completed work. Tasks have become simpler isn’t it? 3D printers give shape to the objects that they have been formulating, one layer each time, as and when the ink is sintered into the required place. The machine uses a laser that helps conclude little wastage and gives structure to the shapes that was essentially impossible to get on to using the usual “subtractive” technology of milling machines, lathes, and cutting tools. Uses a 3D printer can be put to: The object is yet not ready for mass production but still offers many uses and can be put to essential work. 3D printing is considered the best when it comes to creating prototypes, tailoring jobs, short production runs and extruding filaments of molten plastics to create objects like toys, car fittings, mobile phone cases, etc. In these cases there is no requirement of any retool which is introduced each time for making the specification changes. All that one needs to do is change the software that manages or operates the print heads. Other areas where the machine finds application includes, dental and medical industries, geographic locations, educational, information systems and civil engineering firms. Companies are even making efforts to manufacture affordable 3D printers that can be brought to home desktop use. RepRap is one of the longest projects being undertaken for this purpose. Who can use 3D Printers? At present this technological bud has been mostly catering to the aerospace and vehicle industry which requires a quick turning of the experimental designs into metal. The powders that are used in the machine hoppers include waxes, plastics, and foundry sand. The findings and results are forwarded to the foundries, where they utilize it to form moulds for the sand-casting of different metal objects. A car manufacturing company which took months to produce the various parts now takes only two weeks time to cast them into the desired form. With the help of 3D printing they can now print a prototype car engine and cast them using this methodology in just two weeks time. A conventional machine shop would take a longer time as there are many components that they need to form using their hands.

He even gives importance to things like printer ink while printing any official document.
