Foundry: Hierarchical Material Design for Multi-Material Fabrication

on YouTube ↗24m

" summary

A system called Foundry composes parameterized operators into a hierarchical operator graph to define spatially varying materials for multi-material printers, with a library of over 100 operators (subdivide, remap, construct/assign) and a JIT compiler that emits OpenFab “phablets.” Progressive refinement and a cached execution engine give real-time voxel preview at printer resolution. Demonstrations include a functional non‑pneumatic wheel mounted on a tricycle, a ping‑pong paddle, a toddler ski with retroreflectors, and a printed bone model.
