【 摘 要 】

Nowadays, Fused Deposition Modeling (FDM) has accomplished huge proficiency in modelling and wide variety in products shape and size in the industry. Alongside with its development, many problems came up, one of which is to ensure the technical requirements of the parts such as: compressive strength, tensile strength, dimensional accuracy, etc. To solve this problem, new composite materials has been developing and at the same time correlative process parameters has been optimized to achieve the most optimal technical requirements of that material. In this paper, we focus on researching the effect of process parameters consist of: raster angle; build direction and layer thickness on the part's compressive strength made by one of the newest composite material which is the PLA-Copper filament. Central composite design (CCD) methodology is used to lower the experimental runs, the analysis of variance (ANOVA) method is employed to investigate the process parameters in order to achieve optimal compressive strength.
