FreeShell: A Context-Free 4D Printing Technique for Fabricating Complex 3D Triangle Mesh Shells
SessionFabrication
DescriptionFreeShell introduces a robust thermal-shrinkage-actuated 4D printing technique for fabricating freeform thin-shell surfaces. By printing triangular tiles connected by shrinkable connectors using a single material, heating triggers the transformation from flat structures into 3D shells. An optimized mesh layout algorithm ensures geometric accuracy and robustness, reducing material and environment dependency.
