Steps for biomodel acquisition through addtive manufacturing for health

The objective of this study was to describe the main steps in the biomodel manufacturing using an Objet 3D printer (CONNEX 350), whose raw material is a light-curing resin. The steps are adopted by researchers from three-dimensional technologies laboratory (LT3D), of the Center for Strategic Technologies in Health (NUTES), from the State University of Para íba (UEPB), Brazil. It begins with the acquisition of tomographic images that are processed through specific software and exported to the digital Stereo lithography (STL) format. The additive manufacturing technique is Stereo lithography, which consists in the construction of biomodel by photopolym erization of a liquid epoxy resin using ultraviolet radiation. The biomodel that comes from this process was brought to a pressurizing machine to remove the resin support, washing it with water jets. After this step, this biomodel was sent to the health professional in charge. The use of biomodels c onstitutes a major breakthrough in the area of Dentistry, allowing more precise diagnosis by professionals, simulation and surgical planning, previous adaptation of biomaterials and orthoses, as well as interaction between the surgeon and the patient, thus obtaining more satisfactory aesthetic resul ts and decreased surgical time.RESUMO A utiliza ção da prototipagem rápida na área médico-odontológica consiste na obtenção de modelos tridimensionais através de sistemas Computer Aided Design (CAD) e Computer Aided Manufacturing...
