The purpose of this research is to fabricate bio-model that based on Rapid Prototyping technology which is by using Fused Deposition Modeling (FDM) and designing an implant by using a Computer Aided Design technology. A case study from Hospital Kuala Lumpur which is the maxillofacial will be fabricated by using FDM technique. The completed 3D prototype or biomodel will be analyzed to makes the result more truthful in terms of the dimensional accuracy, operational error and cost analysis. Computer aided design technology is used to design the customized implant in order to replace the fractured maxilla part. Introduction Medical field nowadays are facing so many problems related to the bones and also human skeletons. The broken bone need to be replaced with artificial bone due to accident and also other circumstances. The artificial bone that will be replaced the fractured bone need to be precisely identical to be fit into the human body in order to it work properly and avoiding other problems in the future. A biomodel is an object that replicates the geometry or of a biological structure, which can be realized in either a computer based form or a solid physical form [1]. Physical biomodel have advantage compare to 3D virtual model displayed on 2D screen since the application in routine clinical practice was limited [2]. The production of medical models essentially involves reverse engineering, starting with acquiring data as a stack of CT cross-sectional image. Rapid prototyping (RP) is a technique for direct conversion of 3D CAD data into a physical prototype using a number of techniques, mostly based on slicing a 3D object into multiple 2D layers and building them up one layer at a time [4,5]. Problem Statement Doctors and surgeons are facing difficulties to analyze the broken and fractured bone due to some causes or accident. They also cannot do the operation directly to replace the fractured bone, thus it will require some operations that may raise the cost and time of treating patients. By having a prototype as similar model like skull, will help surgeon to analyze the damage part accurately. The CAD software will lead to simplify the surgical simulation and reduce the operation cost. Methodology The general procedure that has been done on this researched that starting with the CT scan data and finally come out with the customized design implant shows in figure 1.
