How Does 3D Printing Work?

You may have heard the hype about 3D printing; the technology that creates 3-dimensional objects by an additive process. But how does this happen? How does 3D Prototype printing work?

The first step in 3D printing is to come up with the design to use. This is achieved by using 3D modelling software to draw a computer aided file. Alternatively, a 3D scanner can be used to copy an existing object and create a 3D digital copy of the object. There are many 3D scanners that apply different mechanisms to obtain the image. The image can then be saved to a PC. As for 3D printing software, it needs to be installed in a PC and used to create a 3D image that will also be saved on the computer.

Once the design is ready, all a person needs to do is connect the PC to a 3D printer and press print.’ Before printing however, be sure to slice the model into hundreds or thousands of horizontal layers using 3D modelling software. The 3D printer will create small pieces of the object first and then join the slice to make tiny layers starting from the bottom up to create a whole object. The items made this way are very sturdy and the materials used are quite a variety. With a 3D printer you can create items from metal, plastic, vinyl and others. They can even join different parts made using different materials in one item.

The technologies used by 3D printers are very different but the final outcome is a complete item built by joining different layers. While some use powder, others use liquid and others filament. 

3D prototype printing has been used in many industries and has actually made things very easy. From baking cakes to making vehicle parts and even making medicines; it has and can be applied in any industry niche. It actually replaces an entire factory with one machine making it easier to make items and ease life.
