DESIGN AND MANUFACTURING OF CUSTOMIZED ANATOMICAL IMPLANTS BY USING RAPID PROTOTYPING TECHNIQUE

Abstract- The development of Rapid Prototyping technology for customized implants that minimize bone removal while maximizing the fit and the “usability ” of the implant. The process involves integrating technologies of Computed Tomography (CT), image processing, Fused deposition modeling (FDM), finite element analysis (FEA), and lost wax casting in the design and fabrication of a near optimal fit between the patient’s bone and the implant component.The analysis verified that the optimized interface surface produced a more even load distribution compared to the “standard ” design. A conservative calculative estimate of 50 % decrease in bone removal may result by adopting the following procedure
