A simple approach for additive manufacturing of inconel 718 with high densification level by fused filament fabrication
“In this study, a simple and low-cost approach to additively manufacture (3D print) Inconel 718 by using a desktop fused filament fabrication (FFF) 3D printer via a 3-step printing-debinding-sintering stage is presented. Inconel 718 filament containing high metal loading (86% by mass) was 3D printed by varying the nozzle temperatures from 210°C to 300°C. As-printed samples were successfully fabricated through all nozzle temperatures without any clogging issues. Debinding and sintering results generally exhibit an increasing trend of densification levels with increasing nozzle temperatures, with the highest relative density of 85% achieved with a nozzle temperature of 290°C. These results show significant promise in the additive manufacturing of metallic materials with high quality just by using the widely available and accessible desktop FFF 3D printers.”
