Summary: We present an end-to-end solution for design and fabrication of soft pneumatic objects with desired deformations. The design results can be fabricated with 3D printing and deformed by a controlled pneumatic system.

Summary: We present MetaSilicones, a method to design and fabricate composite silicone rubbers that exhibit desired mechanical properties. Our MetaSilicones have spherical inclusions of a liquid dopant material embedded in a silicone matrix. We combine extended finite elements (XFEM) and sensitivity analysis to compute inclusion distributions that lead to desired properties.

Summary: Color texture reproduction in 3D printing commonly ignores the heterogeneous volumetric light transport between surface points on the prints. This leads to significant blur of details and color bleeding. We show how to optimize for volumetric material assignments that retain colors and high-frequency details in 3D-printed surface textures.

Summary: We show for the first time how 3D print wireless sensors and input widgets that can communicate with smartphones and other Wi-Fi devices, without batteries or electronics. We present a novel toolkit for wireless connectivity that can be integrated with 3D digital models and fabricated using commodity 3D printers.
