JOULE HEATING FOR IMPROVED INTERLAYER BONDING IN FUSED FILAMENT FABRICATION OF METALLIC OBJECTS

摘要

A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. Joule heating is applied to an interface between adjacent layers of the object by creating an electrical circuit across the interface and applying pulsed current sufficient to join the metallic build material across the adjacent layers.
