Geodesic Slicing: A Generalised Framework for Multi-Axis 3D Printing

Recorded at CDFAM Amsterdam, 2025Alessandro Zomparelli - AiBuild Multi-axis 3D printing has become a widely adopted technology across a range of industries. In recent years, computational designers and engineers have increasingly explored non-planar slicing strategies for large-format and robotic 3D printing in order to produce support-free parts with better strength and surface quality. While many solutions remain tailored to specific applications, the development of more generalised and automated toolpath generation workflows is essential to broaden the accessibility and scalability of these technologies.Geodesic fields offer a highly adaptable approach to 3D volumetric slicing, enabling optimised toolpath generation for complex geometries. This presentation introduces the geodesic slicing framework implemented within Aibuild, showcasing its integration with the platform’s comprehensive suite of design and fabrication tools. The method supports a general-purpose workflow that minimises the need for complex input parameters, making it suitable for a wide range of use cases.We will demonstrate the current implementation and available controls, and present a variety of outputs generated using this method, including freeform surfaces, multi-directional features, and branching structures, highlighting the potential of geodesic slicing to streamline fabrication in both experimental and production environments.
