Abstract

It is necessary to develop optimization methods to improve synthetic bone structure for application in human bone implants. Synthetic bone made of polymethyl-methacrylate (PMMA) composites are frequently employed in the medical field (PMMA, on the other hand, has restricted mechanical qualities, as well as being less compatible, rigid, and non bioactive. This research mixed PMMA material with hydroxyapatite (HA) material. The material's composition is PMMA: MMA = 1: 1, with a hydroxyapatite (HA) to PMMA powder ratio of 0.50: 1 (w/w). The material will be printed through a 3D Printing machine which has a 1.5 mm nozzle. This 3D Printing machine undergoes periodic development, but the results obtained are not in accordance with the needs, especially the tensile strength of the specimen. Therefore, it is necessary to conduct research to optimizing the printing parameters of the 3D Printing machine. Experimental results and analysis using the RSM method show that printing parameters of the 3D printing machine on PMMA/HA material to get the highest tensile strength was at the point of 13.670 mm/s for the perimeter speed parameter, 76.330 mm/s for the infill speed parameter and 33.670% point for the fill density.
