The characterization of silica deposit powder has a significant part in understanding its structure, composition, and potential application. Key aspects of silica deposit powder characterization successfully highlighted. By using silica as a filler system in additive manufacturing is one of the processes that can utilize silica deposit powder. This material has the potential to be used as a reinforcement mixture with SLA resin for 3D printing. The present study discusses the ability to mix specimens of silica (size 600 microns) and resin with a composition ratio of 1%: 100%. This research aims to gain knowledge about the basic characteristics of silica deposit powder for better understanding and efficient utilization in various applications, especially additive manufacturing. This research also examines the most effective particle sizes to use and adjustments to the length of time required for the mixing and curing processes in order to obtain maximum results [1-6].
