文档介绍：What is 3D printing?
3D printing or additive manufacturing is a process of making three dimensional solid objects from a digital file.
It is a rapid prototyping technology,based on the digital model file, using powdery metal , plastic and other adhesive materials, through the layers of the way to build objects to the technology.

FDM（Fused Deposition Modeling）熔融沉积快速成型
By melting the filamentous material，those molten material will melt and squirt out from the will be deposited in the production panel or a layer of solidified the temperature was lower than the curing temperature,It will began to cure, and form the final product through stacking materials layer by layer.
Advantages：
Simple structure
Easy to design
Low manufacturing costs
Main material：
ABS
PLA
Composite

SLA（Stereolithigraphy Apparatus）光固化成型
SLA is the earliest developed rapid prototyping technology, and also is one of the most in-depth,mature and widely used rapid prototyping technology.
The main materials of SLA is photosensitive through ultraviolet light or other light source solidification molding, layer by layer curing, get the final product ultimately.
