Chapter 1: 3D Printing Technology
3D printing refers to 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.
Fused Filament Fabrication (FFF) is the most common method of 3D printing. It
is also the method that the Dreamer NX 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.
1.1 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
1.1.1 Make a 3D Model
Currently, there are three ways of making a 3D model.
·Designing From Scratch You can use free CAD (computer-aided design)
software such as 3DTADA, AutoCAD, SolidWorks, Pro-E, and our own
software Happy 3D, which is suitable for the beginners, to design your own 3D
model.
