10226103 · 2019-03-12 · ·

A footwear insole shape is generated by supplying a core reinforced filament having a matrix material impregnating reinforcing strands aligned along the filament, as well as a fill material separately from the core reinforced filament and depositing at least one shell of fill material within an insole shape upon a print bed. The core reinforced filament is deposited to fuse to the fill material within a first reinforcing region formed with respect to the insole shape. A cutter upstream of the nozzle tip cuts the core reinforced filament, and a remainder of the core reinforced filament is deposited to complete the first reinforcing region. A nozzle tip applies pressure to continuously compact the core reinforced filament toward the insole shape as the core reinforced filament is fused to the fill material.
