Research Progress on Technology,Modification and Application of 3D Printing PETG
Polyethylene terephthalate-1,4-cyclohexane dimethyl ester(PETG)can be used as a preferred polymer material for 3D printing due to its excellent properties,which has been favored by scholars.In this paper,the printing process of PETG was studied,and it was found that the printing direction,printing thickness,printing temperature,printing speed and filling density,and other process parameters would have a significant impact on the performance of the product.The modification of 3D printed PETG material was studied by blending modification methods such as fiber,polymer,and graphene to improve the fatigue resistance,mechanical and thermal properties of the material.The application research of 3D printing PETG in biomedicine,machining and marine fields as well as the feasibility study of recycling were reviewed in detail.Finally,the development prospect of 3D printing PETG in the future was predicted.It is expected to provide guidance for the industrial application of 3D printed PETG materials.
