Structural design and analysis of multi-material 3D printer based on screw extrusion principle

Since traditional fused deposition 3D printers have problems such as low printing efficiency and easy breakage of silk, multi-material 3D printing technology based on screw extrusion principle can effectively solve such problems. Therefore, this paper takes the multi-material 3D printer based on the principle of screw extrusion as the research object, designs, models and builds its structure, and adopts the research method combining finite element simulation analysis and experimental verification to verify that the designed multi-material 3D printer can realize multi-material 3D printing, which has important theoretical guiding value and practical reference significance for engineering applications.
