Before start this article, I’ll try to explain what’s 3D Printing?
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file. 3D printing enables you to produce complex (functional) shapes using less material than traditional manufacturing methods.
How does a 3D printer work ?
It all starts with the creation of a 3D model in your computer. This digital design is for instance a CAD (Computer Aided Design) file. A 3D model is either created from the ground up with 3D modeling software or based on data generated with a 3D scanner. With a 3D scanner you’re able to create a digital copy of an object.
How does a 3D printing pen work?
Like the 3D printer but easier to operate. You need not a computer, nor a software CAD, only a 3D printing pen and some plastic filament (ABS, PLA, PCL, etc), you can free up the imagination, draw a wonderful world in the air.
