Abstract

Micrometric surgical components typically have high geometric complexity and stringent regulatory specifications. These components need to have excellent mechanical properties and a high demand of products. Besides these factors, it is necessary to maintain a low manufacturing cost, performing essential research on new manufacturing technologies. Metal Injection Molding (MIM) is a process that has been explored , providing an interesting alternative for making medical devices. The research in the production of microcomponents obtained for MIM is gaining momentum and prominence, due to low cost and high productivity of this process. This paper is a study and development of feedstocks with AISI 316L alloy , which is known for its biocompatibility. Four feedstocks with 61%vol. of metal powder were analyzed by capillary rheometry and DSC/TGA.
