3D printing has become very popular nowadays. People all over the world use it for different purposes. If you have no idea what this actually means, then you will certainly find very helpful this article as you will actually find out everything you need to know about 3D printing.

What is actually 3D printing?

For a better understanding, what you must know is that 3D printing is actually a manufacturing process. In this process, a material is laid down, layer by layer, really slowly, in order to obtain a three-dimensional object. You must know that the material is actually built from scratch, in comparison with the subtractive processes in which the material is actually milled, cut, or drilled.

How does it work?

First of all, you must create a virtual design of the object you actually want to make. Keep in mind that the virtual design must be made in a Computer Aided Design file, and only by using a 3D modeling program, in case you want to create a new object. On the other hand, if you want to copy an existing object, then it is better to use a 3D scanner. The 3D modeling software will ”slice” the final model into loads of horizontal layers, in order to prepare a digital file for printing. Then, the sliced file must be uploaded in a 3d printer, and once this happens, the object can actually be created, and this must be done layer by layer. Each slice will be read by the 3D printer, and it will start to create the object.

What technology is being used during the whole process?

There are many types of 3d printers that use different technologies. You will probably be surprised to find out that there are some methods that use softening and melting material in order to produce the layers. The most common technologies are Fused Deposition Modeling and Selective Laser Sintering. There are 7 processes used for 3D printing which you must know about: Vat Photopolymerization, Material Jetting, Binder Jetting, Material Extrusion, Powder Bed Fusion, Sheet Lamination, and Directed Energy Deposition.

Where is 3D printing used?

This wonderful technology is being used in the medical industry, aerospace&aviation industries, and automotive industry as well. Domestic 3D printing is actually for enthusiasts who love this domain, and they want to test it. 3D printers are not very expensive nowadays, and therefore, they are affordable for lots of people. This is everything you need to know about 3D printing which is actually an amazing and wonderful technology.
