Abstract—This study explores the application of continuous helical blades in extrusion systems for multiple materials. To enhance the adaptability of extrusion systems to different material properties, the study divides the extrusion system into a main process and sub-branches, with the main process representing the components of the extrusion mechanism, and the variations in component parameters serving as the sub-branches. Once the final product design and chosen printing material are determined, the dimensions of the extrusion head (length, width, and height), as well as the spacing and angle of the continuous helical blades, can be determined. By utilizing Flow Simulation software for analysis, the system's discharge speed and frictional forces under different parameter combinations can be simulated, analyzed, and compared to identify the optimal configuration for specific conditions. This allows for the calculation of the required motor torque to complete the design of the extrusion system components. the objective of this research is to use the assistance of continuous helical blades to facilitate the extrusion process for various materials, ensuring stable printing quality and contributing to the development of 3D printing. The systematic organization and design presented in this study provide valuable reference for future extrusion system developers on how to adjust the parameters of each component to achieve the desired goals when dealing with different material properties. Through experimentation, it was observed that the extrusion system could be driven with minimal power when the dimensions of the extrusion head were set to 8 cm (length), 2.5 cm (width), and 5 cm (height), and when the blade spacing was segmented into four sections and the blade angle was set to 76 degrees, resulting in successful extrusion operations.

Keywords—continuous helical blades, extrusion systems, 3D printing technology, parametric design
