• Best of Congress 2020: Wireless Sensor Measurement in 3D Printed Sand Molds

    Additive manufacturing is enabling the casting of complex geometries directly from digital design data and including 3D-scanned and reversed-engineered structures and even functionally-graded lattices. By inkjetting binder into a bed of sand layer-by-layer, dimensionally-precise sand molds and cores can be printed to serve as soft tooling for sand casting. However,... more
