A solid-state additive manufacturing additive manufacturing system applicable to building up 3D structures, coating and functionalizing surfaces, joining structures, adding customized features to objects, compounding proprietary compositions and repairing various structures is disclosed. The solid-state additive manufacturing system enables deposition of different fillers, viz. metals, metal alloys, MMCs, polymers, plastics, composites, hybrids and gradient compositions, as well as controls the resulting deposit structures, e.g. specific nano-/micro-, gradient- and porous- material structures. The system accommodates various feeding-, spindle- and tool-designs for depositing different forms of filler materials, viz. rods, wires, granules, powders, powder-filled- tubes, scrap pieces or their combination, and a working platform with multiple access points. One or multiple motors, driving and monitoring units control the movement of the workpiece, spindle and tool and move the filler through the feeding system, which passageway is in communication with the passageways of the spindle and the tool.
