Abstract
Additive Manufacturing (AM), commonly known as 3D printing, has revolutionized the field of customized prosthetics by enabling rapid fabrication of personalized devices with complex geometries and enhanced functionality. This paper presents a comprehensive study on the application of additive manufacturing in the design and production of customized prosthetics. The advantages of AM over traditional manufacturing, including design flexibility, cost efficiency, and reduced lead times, are critically analyzed. Various additive manufacturing techniques such as Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), and Stereolithography (SLA) used for prosthetic fabrication are explored. The study incorporates a methodology involving CAD modeling, material selection, and AM process parameters for prosthetic development. Results demonstrate significant improvements in comfort, fit, and mechanical performance of prosthetics manufactured by AM. The challenges and future directions in this interdisciplinary domain are also discussed. This research underscores the potential of AM to enhance patient-specific prosthetic solutions, aligning with the engineering innovations available up to the year 2020.
