This study explores how additive manufacturing (AM) technology can enhance the perceived value of upcycled furniture, addressing current limitations in design quality, reproducibility, and consumer acceptance. Through a comprehensive literature review, the paper identifies key value dimensions—functional, aesthetic, emotional, social, green, and price value—and examines how AM’s unique advantages, including complex geometry, material flexibility, and personalized customization, can strengthen these dimensions. The research highlights that integrating AM technology into furniture upcycling not only improves product aesthetics, performance, and sustainability but also enhances consumers’ perceived value, thereby increasing their willingness to adopt upcycled products. This study provides a theoretical and practical framework for leveraging AM to promote innovation and sustainability in furniture design.
