Classification: CPC B | IPC B

Claim 21:
22. A 3D printing system, comprising:
a printer head;
a base composite material channel located within the printer head and configured to pass a base composite material therethrough, wherein the printer head is configured to extrude the base composite material as a standalone 3D printing material;
a fiber strand channel located within the printer head and configured to pass a fiber strand separate from the base composite material therethrough, wherein the fiber strand channel meets the base composite material channel at a first location within the printer head;
an impregnation material channel located within the printer head and configured to pass an impregnation material therethrough to impregnate the fiber strand while the fiber strand is within the printer head, wherein the fiber strand channel meets the impregnation material channel at a second location within the printer head that is before the first location; and
a fiber feeding component located within the printer head and configured to feed the fiber strand through the fiber strand channel, wherein the fiber feeding component facilitates impregnating the fiber strand with the impregnation material at the second location to form an impregnated fiber strand and also facilitates combining the impregnated fiber strand with the base composite material at the first location to form a combined 3D printing material within the printer head, and wherein the printer head is also configured to extrude the combined 3D printing material including the base composite material and the impregnated fiber strand.
