What is it about?
Multi-axis motion introduces more degrees of freedom into the process of 3D printing to enable different objectives of fabrication by accumulating materials layers upon curved layers. This paper presents a general slicing framework for achieving multiple fabrication objectives including support-free, strength reinforcement, and surface quality.

Why is it important?
An existing challenge is how to effectively generate the curved layers satisfying multiple objectives simultaneously. These objectives are formulated as local printing directions varied in the volume of a solid, which are achieved by computing the rotation-driven deformation for the input model. The deformation can be effectively optimized with the help of quaternion fields to achieve the fabrication objectives. The effectiveness of our method has been verified on a variety of models.
Perspectives
It is my pleasure to collaborate with co-authors from our research group and the professor from INRIA, I hope this work can provide a general solution for the curved 3D printing community. The algorithm can be further extended to specific needs, such as unsupported metal printing, and carbon fibre strength-enhancing printing.
