Abstract
En el siguiente trabajo se plantea un análisis comparativo entre dos metodologías de fabricación que emplean métodos pulvimetalúrgicos que permiten obtener piezas sinterizadas base titanio, con agregado de hidroxiapatita como material bioactivo. El primer método utiliza técnicas tradicionales de obtención de muestras por compactación de polvos a través de prensas y matricería metálica. El segundo método emplea la técnica de gel-casting combinada con la tecnología de impresión 3D para la fabricación de moldes. Se lleva a cabo un análisis de los métodos de manufactura, la tecnología empleada en el desarrollo de moldes, las variables de sinterización y las propiedades mecánicas, tales como el módulo de elasticidad, resistencia mecánica, límite de fluencia, elongación y dureza de los materiales de titanio e hidroxiapatita obtenidos.
The following work presents a comparative analysis between two manufacturing methodologies that use powder metallurgical methods, that allow obtaining titanium-based sintered parts with the addition of hydroxyapatite as a bioactive material. The first method uses traditional techniques for obtaining samples by powders compaction through presses and metal molds. The second method employs the gel-casting technique combined with 3D printing technology for mold making. An analysis of the manufacturing methods, the technology used in the development of molds, the sintering variables and the mechanical properties about titanium and hydroxyapatite´s samples is carried. Some of the mechanical properties that will be analyzed are the modulus of elasticity, mechanical resistance, yield point, elongation and hardness.
