英文摘要：

Aiming at desktop 3D printing application process issues of PLA,PLA material desktop 3D printing applications was studied,describes the process of PLA material desktop 3D printing,comparing the different layer thicknesses set time and precision machining influence,proposed under accuracy,time and three common model 3D printing process table. The table was used to form different products. Aiming at defects in material properties of PLA,the most commonly used method for modifying was summarized. And described composite technology is simple,could effectively improve the mechanical properties of PLA and to improve its heat resistance. The results indicate that the proposed technical parameters table can effectively guide the PLA material Desktop 3D printing applications,the composite technology is a reliable method of PLA material modification.
