The 3d Printing Technology

1 Introduction.

The idea of a do-it-yourself manufacturer is really coming to the forefront thanks to"3-D printer" It is one of the most exciting innovations to emerging technology in recent times. The 3D printing technology made its way to the technological world , this technology may be closer than you think. 3-D printing is making it easier and faster to produce complex objects with multiple moving parts and complex design. It extended the realistic possibility that anyone, anywhere in the world can produce any object they need on demand.

1.1 What is 3D –printing?

3D printing is a form of additive manufacturing technology where a three dimensional object is created by laying down successive layers of material. It is also known as rapid prototyping, It is a prototyping process whereby an real object is created from 3D design. Designers create models using computer-aided design (CAD) software, and then machines follow that software model to determine how to construct the object. The digital 3D-model is saved in STL format and then sent to 3D printer and then it print the design layer by layer and form a real object.3D printer is also known as desktop fabrication. Now, a complete model can be created in a single process using 3D printing.

1.2 Origin of 3D-Printing.

In the 1986 year the 3D printing technology made its way to the technological world , but not gain importance until 1990. 3D printer was not that much popular in some areas like engineering, architecture and manufacturing.

Chuck Hull is the co-founder and inventor of 3-D system for printing physical 3D objects from digital data in 1984.In 1986 he named the technique as stereo lithography and obtained patent. Stereo lithography (3D Printing),the first commercia...

Time required for the printing actually depends on the real size of the item that is being created. Usually small and tiny objects like a few cubic inches or a tall, and thin substance gets printed quickly, while bigger and larger, more complex objects take longer duration to get printed. FDM is a slow process if we compare it with stereo lithography or selective laser sintering.

The support items and materials are taken away after an object comes into existence by drenching it in water and detergent solution or in the case of thermoplastic supports and ripping off the support materials by hand. The newly created items may also be plated, sanded, milled or painted to improve their function and appearance.
