Structural design of a novel rotary platform 3D printer

Abstract Stair-stepping defects in 3D printing processes can be caused by various reasons, such as the quality of the printing material, the position of the print head, printing speed, printing temperature, and so on. To improve the issue of stair-stepping effects in thin-walled revolving parts during the 3D printing process, this project aims to design a 3D printer that enables the print head to move in the X, Y, and Z axes while the heated bed platform can rotate. This will significantly reduce the stair-stepping effect’s impact and greatly enhance the printing’s quality and accuracy.
