This paper proposes a procedural metamaterial that produces an orthotropic elastic behavior, with different degrees of elasticity along orthogonal directions. The orientation and strength of orthotropy is freely controllable in space, without requiring further optimization. Compared to isotropic materials, this better adapts to uneven load scenarios and offers greater design flexibility.

Most additive fabrication technologies use a fixed, small discrete set of materials. A broad range of continuously varying elastic properties can be obtained using microstructures, but these may be fragile because of stress concentrations. This paper introduces a method for optimizing worst-case stress leading to significant reductions in maximum stress.

A printer that embeds magnetic flakes in a photo-cured resin, allowing orientation distribution of the flakes to be controlled with a magnetic field at fabrication time. The paper demonstrates optical effects including bump maps: flat surfaces with spatially varying specular lobe direction.

Introducing a novel color-reproduction method for 3D printing. In contrast to current halftoning techniques that use surface-color mixing, this technique mixes colors inside the printed volume, which mitigates the variety of artifacts associated with color halftoning.
