Description

Ovenbird is a free Grasshopper plug-in that generates, analyzes, and optimizes 3D printing toolpaths for concrete and other large-format materials with the extended functionality of gradient multi-material printing.

Ovenbird is the product of the 3D concrete printing research and the gradient multi-material extrusion research at the Polyhedral Structures Laboratory (PSL), which is part of the Weitzman School of Design at the University of Pennsylvania.

The plug-in is named after the red ovenbird (Furnarius rufus, also known as the rufous hornero), a South American bird that builds its shell nests by gradually depositing mud, a process similar to 3D concrete printing. We share the ovenbird’s vision of printing our own houses.
