A Toolpath Design Platform for Multi-material Layered Manufacturing

Computer-Aided Design and Applications, 2011
AbstractToolpath planning is vital to multi-material layered manufacturing (MMLM), particularly for improvements in fabrication efficiency and quality of prototypes. This paper proposes a toolpath design platform (TDP) for planning and validation of toolpaths in MMLM.

Fabrication‐Directed Entanglement for Designing Chiral and Anisotropic Metamaterial Foams

Advanced Engineering Materials, Volume 28, Issue 2, 21 January 2026.
This work introduces fabrication‐directed entanglement (FDE), combining viscous thread printing and topology optimization to program entangled foams with spatially patterned stiffness. By tuning coil density, FDE enables anisotropy, programmable Poisson's ratio, and chirality in foams.

A level set based method for fixing overhangs in 3D printing [PDF]

, 2017
3D printers based on the Fused Decomposition Modeling create objects layer-by-layer dropping fused material. As a consequence, strong overhangs cannot be printed because the new-come material does not find a suitable support over the last deposed layer ...

Programmable Compliance in Small‐Diameter Vascular Grafts by Design of Melt‐Electrowritten Scaffold Architectures for In Situ Tissue Engineering

Advanced Healthcare Materials, Volume 15, Issue 2, 14 January 2026.
Small‐diameter vascular grafts with compliance tunable by design are fabricated via melt electrowriting. By controlling the winding angle of intertwined helical fibers, grafts with compliances matching those of human vessels, from veins to arteries, are realized. This holds the potential of avoiding a compliance mismatch, which has been identified as a
