NURBS 体参数化模型的无支撑打印算法.

Achieving unsupported 3D printing still faces challenges in handling large-angle overhangs and improving printing precision. This paper presented a cone slicing algorithm for multi-freedom unsupported 3D printing of NURBS volume parametric models. Though the geometric mapping of the 3D model file of the model, it applied a horizontal slicing algorithm to this mapped model, resulting in a continuous print path G-code of the deformed model. This G-code was then subjected to inverse mapping, generating multi-degree-of-freedom continuous printing paths suitable for six-axis robotic arms. Utilizing the conical slicing algorithm to plan printing paths enabled printing of overhanging structures without the need for support. It validates the accuracy, feasibility, and effectiveness of the conical slicing algorithm through simulation experiments and comparative trials. The introduction of the conical slicing algorithm offers a more efficient, economical, and green solution for unsupported 3D printing of NURBS-based parametric models. [ABSTRACT FROM AUTHOR]
