Abstract

Additive manufacturing is becoming increasingly popular in industries such as manufacturing due to its ability to use raw materials more efficiently and require less machining than traditional methods(Calignano et al., 2017). However, constructing overhanging structures in additive manufacturing can be challenging, potentially affecting the overall geometric quality of the printed components. The objective of this study was to identify the most effective printing orientation for overhanging designs in Fused Deposition Modeling (FDM) using two different support structures. To achieve this, the researchers used a laser scanner to collect point cloud data and conducted a comparative study to determine the optimal orientation for the overhanging structures. The analysis revealed that the 45-degree overhang structure with grid support produced a good print result compared to other build orientations. Additionally, a comparison of FDM printed parts and L-PBF printed parts showed some similar noticeable defects.
