Abstract

The application of Additive Manufacturing has brought progress and transformation in the industrial world. 3D printing technology is advantageous over traditional manufacturing processes, as it can turn 3D designs/models into ready-to-use products. This research aims to identify the wax printing process as a printing model for the craft industry using additive manufacturing-based technology. Studies related to wax printing technology using a 3D printer to print handicrafts are needed to find out the characteristics of wax as the primary printing material, what parameters of the printing process are required for the wax printing process, and what kind of 3D printing technology is appropriate in the wax printing process, especially for use in the craft industry. Testing wax model printing using an FDM 3D Printer with the most suitable heating temperature of 200⁰C and a retract distance of 50 mm using wax material in the filament. Shrinkage resulting from the wax printing process has a minimal value, with an average minimum shrinkage of 1.16% and a maximum average enlargement of 0.02%, which indicates that this technology is suitable for use in the printing process of handicraft models.
