This article presents a study on the reverse design and additive manufacturing of furniture protective foot covers. The research focuses on developing customised foot covers that fit the shape of chair feet and provide cushioning and noise reduction. The study uses flexible polylactic acid (PLA) filaments combined with reverse design and additive manufacturing technologies. The process involves 3D scanning of the chair feet, creating a triangular mesh model, and using SolidWorks software for reverse design. The foot covers are then manufactured using FDM 3D printing technology with specific slicing parameters to ensure good layer adhesion and structural integrity. The protective foot covers were tested for their cushioning and noise reduction effects. Finite element simulation results showed that the maximum stress value of the European-style chair with protective foot covers decreased by 90.8% in the case of vertical fall, indicating a significant buffering effect. Noise tests revealed a 51.0% reduction in noise levels, demonstrating the effectiveness of the foot covers in reducing noise. The study concludes that the combination of reverse design and additive manufacturing provides a practical solution for customised furniture protective foot covers, offering both cushioning and noise reduction benefits. The results highlight the potential of these technologies in creating customised products that meet specific functional requirements.This article presents a study on the reverse design and additive manufacturing of furniture protective foot covers.
