摘要：
Fused filament fabrication (FFF) is an additive manufacturing technology that forms three-dimensional (3D) entities by stacking and accumulating extruded material filaments. However, the surface quality of FFF products has obvious defects due to the layer-by-layer manufacturing characteristics. To effectively improve the FFF products’ surface quality, it is necessary to analyze the generation mechanism of surface roughness. Based on the bonding neck forming process, the surface profile of the material filament was investigated, and the theoretical model of the sample’ s surface roughness in two directions (vertical and parallel to the fiber direction)was established based on the transverse and longitudinal bonding neck forming process. The FFF sample was prepared, and the surface roughness of the sample was obtained using a laser microscope. The theory and experimental results verified the correctness of the model, providing theoretical basis and technical support for improving the surface quality of FFF products. © 2022 Northeastern University.
