1. What is 3D printing?

3D printing is also known as desktop fabrication or additive manufacturing. It is a prototyping process whereby a real object is created from a 3D design.

 Et al [1] the chemical post treatment does not require human intervention and has led to a significant improvement in surface finish at the expense of a negligible change in the prototype size.
 Et al [3] the surface finish can be improved by choosing suitable build orientation of the part. It can also be increased by reducing the layer thickness of build material.
 We have coating parts with epoxy resins and paints; this is by far the easiest method, and is great for beginners.
 Et al [3] it will increase the build time. Some authors has reported that proper setting of FDM machine parameters may lead to better surface finish.
 Et al [3] Out of post processing techniques, chemical treatment has been used successfully by some researchers to produce a very good surface finish.
 Et al [4] the material property geometry and accuracy influence the 3D model build by PLA and polyamide were compared on the quality prototype. Quality prototype build by polyamide 3D material in the powder form using SLS process were acceptable when compared the prototype build by PLA 3D material in the filament form using FDM
