1、3DPrinting3D打印英文介绍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 t

2、he way to build objects to the technology.Three elementsdigital file3D printermaterial 3D printing mainstream technologyFDM（Fused Deposition Modeling）SLA（Stereolithigraphy Apparatus）3DP（Three Dimensional Printing and Gluing）SLS(Selecting Laser Sintering)FDM（Fused Deposition Modeling）熔融沉积快速成型熔融沉积快速成型

3、By melting the filamentous material，those molten material will melt and squirt out from the nozzle.It will be deposited in the production panel or a layer of solidified material.When the temperature was lower than the curing temperature,It will began to cure,and form the final product through stacki
