A feeder system includes a donut-ring-shaped first wheel having a first groove recessed below its top surface, with a first hopper positioned above to receive material. A first conduit connects the hopper bottom to the groove, defining a feeding path. A mixer unit receives materials, connected to the first groove via a first suction head. A first motor rotates the first wheel, transferring material from hopper to groove to mixer unit. A donut-ring-shaped second wheel includes a second groove, second hopper, and second conduit. A second suction head connects this groove to the mixer unit, while a second motor enables wheel rotation for material transfer. The mixer unit combines both materials. The feeder system implements coaxial wheel arrangement with independent material flow control, enabling independent powder delivery for additive manufacturing applications.

A multi powder mixing system includes first, second and third wheels each having a first groove recessed below its top surface, with first, second and third hoppers positioned above the wheels. First, second and third conduits connect the hopper bottoms to the grooves, defining feeding paths. A mixer unit receives materials, connected to the grooves via first, second and third suction heads. First, second and third motors rotate the respective wheels, transferring powdered materials from the hoppers to the grooves to the mixer unit. The mixing system has a coaxial wheel arrangement with independent material flow control providing controlled powder mixing.
