Rotational Axis A rotational axis is an additional degree of freedom in 4-axis or 5-axis 3D printers, allowing rotation of the print bed or nozzle. It enables non-planar printing, complex geometries, and overhang-free designs. Rotational axes improve surface finish, mechanical strength, and print efficiency by eliminating support structures. Advanced printers synchronize rotational movements with linear axes for accurate multi-angle printing. Proper configuration enhances flexibility, precision, and design possibilities, expanding applications in aerospace, automotive, and artistic sculptures. |
