AI Technical Summary
Traditional 3D printing devices with fixed extrusion port diameters face issues of non-uniform material flow rates when adjusting port size, leading to reduced printing quality due to material squeezing, which affects printing accuracy and efficiency.
A 3D printing device with a variable extrusion port size, where the feeding and discharging portions are configured to move relative to each other along the axial direction of the inner cylinder, allowing the extrusion port to change length and width by adjusting the number of hole channels in communication, thereby avoiding material squeezing and ensuring uniform flow.
This solution improves printing quality by maintaining uniform material flow rates and allowing for flexible adjustment of printing thickness and accuracy, enhancing both efficiency and precision in 3D printing processes.
