SUMMARY:Curve-Based Slicer for Multi-Axis DLP 3D Printing
DESCRIPTION:Chengkai Dai (Centre for Perceptual and Interactive Intelligen
 ce (CPII) Limited); Liu Tao (The University of Manchester); Dezhao Guo and
  Binzhi Sun (The Chinese University of Hong Kong); Guoxin Fang and Yeung Y
 am (The Chinese University of Hong Kong, Centre for Perceptual and Interac
 tive Intelligence (CPII) Limited); and Charlie C.L. Wang (University of Ma
 nchester)\n\nThis paper introduces a novel curve-based slicing method for 
 generating planar layers with dynamically varying orientations in digital 
 light processing (DLP) 3D printing. Our approach effectively addresses key
  challenges in DLP printing, such as regions with large overhangs and stai
 rcase artifacts, while preserving its intrinsic advantages of high resolut
 ion and fast printing speeds. We formulate the slicing problem as an optim
 ization task, in which parametric curves are computed to define both the s
 licing layers and the model partitioning through their tangent planes. The
 se curves inherently define motion trajectories for the build platform and
  can be optimized to meet critical manufacturing objectives, including col
 lision-free motion and floating-free deposition. We validate our method th
 rough physical experiments on a robotic multi-axis DLP printing setup, dem
 onstrating that the optimized curves can robustly guide smooth, high-quali
 ty fabrication of complex geometries.\n\nRegistration Category: Full Acces
