A technique utilized by printers using the Composite Extrusion Modeling process where a lattice of cube-shaped voids are built inside a part using standard layered material extrusion. Once the height of a set of voids is built, the extruder head is used to fill the void with polymer by injecting the polymer from the nozzle, not by tracing a layer. This creates a solid cube of polymer without layers that fill the lattice created with layers. The cubic voids are created at alternating heights to create a brick-like structure in the part. This creates a fully filled part with significantly higher strength in the Z-direction.
