How Does 3D Printing Work?

1. A blueprint of a 3D object is created using computer modeling software.

2. Using a process called slicing, the model is divided up into thousands of horizontal layers. The size, orientation, density and other such factors are selected.

3. The object is then built by adding or ‘printing’ one layer on top of another by melting the raw material and depositing it on the print platform as specified by the design.

4. The 3D printed model undergoes finishing touches such as sanding, painting, polishing or other such techniques which are typically done by hand.
