3D printing technology is getting popular day by day. A lot of 3D printing startups are also rising rapidly. 3D printing is comparatively cheaper and produces quality prototypes compared to traditional printing solutions.

What is 3D printing?

3D printing is an additive printing technique and completely opposite of subtractive printing techniques. Three-dimensional objects are printed using the 3D printer.

3D printing works on a layer by layer additive process. The 3D printer takes a 3D design from the computer and starts adding layer after layers to achieve the designed pattern.

How does a 3D printer work?

If you understand how a normal inkjet printer works; it’s pretty easy for you to understand the 3D printing. Step by step processes of 3D printing techniques is given below.

  1. Think about a normal printer, you need to Doc or PDF file to print. In 3D printer, you also need a file which contains the 3D design model.

This 3D model is known as Computer Aided Design (CAD) file. You can easily change/modify or create a 3D design model using modern computer software.

  1. When your 3D design is ready you need to fill the 3D printer’s filament with raw materials as like you fill the ink cartridges for inkjet printers.

You can buy 3D printers raw materials and easily fill them. You can use plastic, Nylon, Resin, Ceramic, Gypsum and other available materials.

  1. Once you fill up the 3D printer with enough raw materials you are now fully ready to print your 3D objects.

Once you hit the print command your computer will send instructions to a 3D printer and 3D printer will start adding materials layer by layer until the designed 3D objected created. This is as simple as normal inkjet printers.
