ITIL: Interlaced Topologically Interlocking Lattice for continuous dual-material extrusion Open
Material Extrusion (MEX) systems with dual-material capability can unlock interesting applications where flexible and rigid materials are combined. When chemically incompatible materials are concerned the adhesion between the two might be …

Variable-width contouring for additive manufacturing Open
In most layered additive manufacturing processes, a tool solidifies or deposits material while following pre-planned trajectories to form solid beads. Many interesting problems arise in this context, among which one concerns the planning o…

A Framework for Adaptive Width Control of Dense Contour-Parallel Toolpaths in Fused Deposition Modeling Open
3D printing techniques such as Fused Deposition Modeling (FDM) have enabled the fabrication of complex geometry quickly and cheaply. High stiffness parts are produced by filling the 2D polygons of consecutive layers with contour-parallel e…

CrossFill: Foam Structures with Graded Density for Continuous Material\n Extrusion Open
The fabrication flexibility of 3D printing has sparked a lot of interest in\ndesigning structures with spatially graded material properties. In this paper,\nwe propose a new type of density graded structure that is particularly designed\nf…
