SustainaPrint: Making the Most of Eco-Friendly Filaments

We present SustainaPrint, a system for integrating eco-friendly filaments into 3D printing without compromising structural integrity. While biodegradable and recycled 3D printing filaments offer environmental benefits, there is a trade-off in using them as they may suffer from degraded or unpredictable mechanical prop…

FabObscura: Computational Design and Fabrication for Interactive Barrier-Grid Animations

We present FabObscura: a system for creating interactive barrier-grid animations, a classic technique that uses occlusion patterns to create the illusion of motion. Whereas traditional barrier-grid animations are constrained to simple linear occlusion patterns, FabObscura introduces a parameterization that represents…

Meta-antenna: Mechanically Frequency Reconfigurable Metamaterial Antennas

We introduce Meta-antenna, a design and fabrication pipeline for creating frequency reconfigurable antennas while making use of a single type of mechanical metamaterial structure. Unlike traditional static antenna systems with fixed radiation patterns and frequency responses per geometry, Meta-antenna leverages mechan…

Polagons: Designing and Fabricating Polarized Light Mosaics with User-Defined Color-Changing Behaviors

Polarized light mosaics (PLMs) are color-changing structures that alter their appearance based on the orientation of incident polarized light. While a few artists have developed techniques for crafting PLMs by hand, the underlying material properties are difficult to reason about; there exist no tools to bridge the hi…

Fabricaide: Fabrication-Aware Design for 2D Cutting Machines

Designers of machine-cut objects must often consider whether and how their design can be fabricated with their available materials. In contrast to tools that support preparing finished designs for fabrication, we investigate shortening the feedback loop between design creation and fabrication preparation. To this end,…

Sprayable User Interfaces: Prototyping Large-Scale Interactive Surfaces with Sensors and Displays

We present Sprayable User Interfaces: room-sized interactive surfaces that contain sensor and display elements created by airbrushing functional inks. Since airbrushing is inherently mobile, designers can create large-scale user interfaces on complex 3D geometries where existing stationary fabrication methods fail. To…
