"large-scale parts (table legs, chair frames), lower cost, but cannot achieve high resolutions... printed in seconds, cools in minutes... depositing 700°C aluminum through ceramic nozzle along predefined path into bed of 100-micron glass beads... >10X faster... variables: amount of molten material held in crucible, print bed depth, nozzle size and shape (changing nozzle depth alters metal thickness)... numerical model estimates amount of material that will be deposited into print bed... future: melt and use recycled aluminum"
