FOOTWEAR FABRICATION BY COMPOSITE FILAMENT 3D PRINTING

摘要

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.

1. A method of reinforcing a footwear insole shape, comprising:
supplying a core reinforced filament having a matrix material impregnating reinforcing strands aligned along the filament; supplying a fill material separately from the core reinforced filament; depositing at least one shell of fill material within an insole shape upon a print bed; depositing the core reinforced filament to fuse to the fill material within a first reinforcing region formed with respect to the insole shape; actuating a cutter upstream of the nozzle tip to cut the core reinforced filament; depositing a remainder of the core reinforced filament to complete the first reinforcing region; and applying pressure with a nozzle tip to continuously compact the core reinforced filament toward the insole shape as the core reinforced filament is fused to the fill material.
