3D printing and 3D scanning technologies have become pivotal tools in the medical field, especially for the design and fabrication of customized medical devices. This study focuses on the development and testing of a novel composite 3D-printed pneumatic artificial muscle exoskeleton robot designed to assist the human hand in heavy weight lifting. We fabricate the load-bearing frame using 3D printing technology and carbon fiber-reinforced plastic materials. This frame aims to assist individuals with mobility impairments, workers in industrial environments, and patients requiring rehabilitation after injury. The product, fully personalized through 3D scanning technology, ensures high precision and comfort for the user. This paper provides an overview of the research's significance, the design and fabrication methods, as well as the results from product testing. The load-bearing frame is not only lighter than traditional alternatives but also offers enhanced strength and load-bearing capacity with the support of pneumatic artificial muscles. Furthermore, the study explores the economic advantages, potential practical applications, and the opportunity to replace costly imported products with locally produced solutions at more affordable costs. The findings from this research contribute to improving treatment outcomes and quality of life for patients while also opening new avenues for the application of 3D printing and scanning technologies in healthcare sector.
