1. A powder mixing system, comprising:
a first wheel that is donut-ring-shaped and has a first groove recessed below a top surface of the first wheel;
a first hopper positioned above the first wheel and configured to receive a first powder;
a first conduit connecting a bottom of the first hopper to the first groove and defining a first feeding path for the first powder;
a mixer unit;
a first suction head having a first end connected to the first groove and a second end connected to the mixer unit;
a first motor configured to rotate the first wheel so that the first powder is transferred from the first hopper to the first groove via the first conduit and then to the mixer unit via the first suction head;
a second wheel that is donut-ring-shaped and has a second groove recessed below a top surface of the second wheel;
a second hopper positioned above the second wheel and configured to receive a second powder;
a second conduit connecting a bottom of the second hopper to the second groove and defining a second feeding path for the second powder;
a second suction head having a first end connected to the second groove and a second end connected to the mixer unit; and
a second motor configured to rotate the second wheel so that the second powder is transferred from the second hopper to the second groove via the second conduit and then to the mixer unit via the second suction head,
a third wheel that is donut-ring-shaped and has a third groove recessed below a top surface of the third wheel;
a third hopper positioned above the third wheel and configured to receive a third powder;
a third conduit connecting a bottom of the third hopper to the third groove and defining a third feeding path for the third powder;
a third suction head having a first end connected to the third groove and a second end connected to the mixer unit; and
a third motor configured to rotate the third wheel so that the third powder is transferred from the third hopper to the third groove via the third conduit and then to the mixer unit via the third suction head,
a shaft extending through a center of the first wheel, a center of the second wheel, and a center of the third wheel such that the first, second and third wheels are coaxially nested in order of the first wheel, the second wheel, and the third wheel,
a first sensor positioned below the first hopper and configured to measure a weight of the first hopper and the first powder therein;
a second sensor positioned below the second hopper and configured to measure a weight of the second hopper and the second powder therein;
a third sensor positioned below the third hopper and configured to measure a weight of the third hopper and the third powder therein,
wherein the mixer unit is configured to mix the first powder, the second powder and the third powder.
