Get To Know About 3D Printing?

It becomes possible to make or create three-dimensional solid substances with the help of digital file in the process of additive manufacturing or 3D printing. In the additive process, we can create 3D printed object. At the time of the additive process, an object is manufactured by laying down consecutive layers of substances till the entire object is shaped.

How does 3D printing work?

First of all you need to create the virtual design of the object that you wish to make. After that this virtual design is prepared in a Computer Aided Design or CAD file with the help of 3D modelling program which is used to create the completely new object or with the help of 3D scanner. Different technologies are used to create a 3D object, and some of them are volumetric scanning, modulated/ structured light, time-of-flight and many more. In recent times, so many IT corporations like Google or Microsoft facilitated their hardware to execute 3d scanning; Microsoft’s Kinect is one of the great examples. In future, you will see the revolutionary changes in devices like smart phones that will have the feature of incorporated 3d scanners. It will become easy to digitize the real objects into 3d models.

Processes and technologies

Different 3D printers use different technologies and can be done in various ways at, and all are preservative and contradictory in terms of usage of layers to make the final object. There are some methods in which softening or melting ways are adopted to generate the layers. These ways of printing are used by some technologies like fused deposition modelling or FDM or Selective laser sintering or SLS. This method is also used by stereo lithography (SLA).


There are varieties of applications, and some of them are entertainment and healthcare/retail, geospatial, education, architecture, metal casting, CAD/ prototyping and design visualization.

Also, there are some other kinds of applications that include

  • Replicating invaluable and antique artefact’s in archaeology
  • Restructuring vestiges in palaeontology
  • Restructuring body parts and bones in forensic pathology
  • Restructuring that is the seriously injured confirmation obtained from crime scene enquiries.

There are many kinds of printings done in market, and some of them are given below:

Personal printing

Enthusiasts and hobbyists are the main users of domestic 3D printing and Personal 3D Printing. Printers get cheap with the swift expansion of this new market. Most of the persons prefer to use MakerBot 3d printer because of its reliability and durability. Varieties of printers are available in the market with the range of $250 – $2,500 so that it can be used by more persons.

Industrial printing

3D printing is very famous and well-known methods, but most of the people are not aware about it. Lots of manufacturers use these printers in the process of designing so that the prototypes for conventional manufacturing can be created, and 3D printers for such kind of reasons are called rapid prototyping.
