1. An apparatus for constructing a cellular matrix structure, the apparatus comprising:
- a. an extruder for extruding cellular matrix structure components, the extruder further comprising a nozzle body comprising an extrudate pathway extending to an extrudate orifice in the nozzle body, the extruder configured to extrude a multi-arm cross sectional shape comprising at least two arms extending away from a central portion of the multi-arm cross sectional shapewherein the nozzle body further comprises a coolant pathway located at least partially between at least two of the arms of the multi-arm cross sectional shape and extending at least partially through the nozzle body;
b. a multi-axis movement device for moving the extruder along multiple predetermined paths while the extruder is extruding structural components to place the structural components in desired positions and connected to selected ones of other components as the components are produced, andc. a controller for moving the extruder and controlling operation of the extruder.

Abstract
Freeform, additive manufacturing equipment, processes and products, including residential, commercial and other buildings. A movable extruder places extrudate that solidifies in open space to create “scaffolding” or “skeletons” of buildings and other products. Elongated extrudate elements are fused to each other or connected by other means to form a cellular structure. Filler material such as polymeric insulating foam may simultaneously or thereafter be placed within the cellular structure to contribute desired strength, rigidity, insulative, barrier or other properties. Finish materials may also be applied.
