3D Printer Technology

The root idea of three-dimensional (3D) printing technology is generated from the prototyping collaborate with the ink jet systems. 3D printing tech is a form of additive manufacturing which produce three dimensional products in colours.  This technology was introduced in the year 1986, but it was not famous until 1990’s. Since 2000 this technology is growing bigger because the cost of 3D printers is cheaper and affordable along it is hands-free post process. Before this technology was introduced, it usually took several days for a skilled labour to create a (one) prototype. It is capable of building extreme geometries and detailed small features and thin wall models. 3D technology is being widely used in many fields such as jewellery, architecture, engineering and construction, automotive, education, aerospace, and medical industries. A large number of competing technologies are available to do 3D printing.

How does a 3D printing system work? Or a 3D object be created?

A 3D printer operates by loading a 3D computer file and multiple layers are printed, piled on top of each other and coloured with standard printing inks. More specifically, 3D Printers perform 5 basic process functions to create a three-dimensional modal.

1. The Print Surface is fed with a unique powder (e.g. plaster, corn starch and resins).
2. The powder is spread on print surface by a roller at a preset depth and this process complete within seconds.
3. After that, colour is applied to the powder’s initial layer by the inkjet print heads.
4. The solidification of powdered layer takes place.
5. The lowering of print surface for powder’s another layer is enabled.

These process repeat until a whole perfect 3D object is created and it is considered as one of the fastest method.

There are lot methods of printing. Each technology has its own merits and demerits. The productive of the 3D printer’s dependent of size quantity and complexity. Nonetheless, the main factors to be considered are speed of finishing, cost of the object and the printer, materials used (powder or polymer) and colour capabilities.
