Abstract

The ability of porous biomedical implants to stimulate bone tissue formation has been shown to improve biocompatibility and osseointegration. Since the modulus of elasticity of human bone and implant material differs, porous implants may also provide less protection against stress. This study looked into how porosity control was achieved in AISI 316L bone implant material using PU sponge as the foaming agent. A duplicate template for pore production is used in the suggested method, which is PU sponge media. By combining distilled water with 1% weight tapioca flour to create a green body, PU sponges with porosities of 20, 25, 30, and 35 PPI are impregnated with AISI 316L metal slurry. By measuring the density of PU sponge throughout the creation of green bodies, porosity control was accomplished. Using an optical microscope, the development of the porous AISI 316L’s physical and microstructural characteristics was examined. Using an optical microscope at a specific magnification, the powder necking phenomenon was seen. The findings indicate that when the density of PU sponge increases, sample porosity increases as well. Nonetheless, the porosity of the AISI 316L biomaterial decreases as the sintering temperature rises. As the sintering temperature and PU sponge density increase, the sample keeps getting smaller. When creating porous materials for orthopedic implants, the study’s findings can be consulted.
