Chapter 1: 3D Printing Technology

1.1 Definition
3D printing is transforming three-dimensional models into physical objects that you
can hold and touch. It is also called additive manufacturing because the 3D model is
created by "adding" layers upon layers of material until the object is fully formed.
1.2 Technique
Fused Filament Fabrication(FFF) is the most common method of 3D printing. It is
also the method that the Finder uses. It works by melting plastic material called
filament onto a print surface in high temperature. The filament solidifies after it cools
down, which happens instantaneously after it is extruded from the nozzle. 3D objects
are formed with the filament laying down multiple layers.
1.3 Process
3D printing involves three steps:
1.) Make or download a 3D model
2.) Slice and export the 3D model
3.) Build the 3D model
①Make a 3D Model: Currently, there are three ways of creating a 3D model.
·Designing From Scratch You can use free CAD (computer-aided design) software
such as AutoCAD, SolidWorks, Pro-E to design your very own 3D model.
·3D Scanners An alternative method to creating a 3D model is to scan an
