Abstract
A three-dimensionally printed structure is provided. The three-dimensionally printed structure includes a first layer composed at least in part of a first material; a second layer composed at least in part of the first material, the second layer being positioned over, under, or through the first layer and having an interface with the first layer; and a first internal structure composed at least in part of a second material different from the first material, the first internal structure being situated in both the first layer and the second layer.
Claims7
A method for printing a three-dimensionally printed structure, the method comprising:
- laying down at least two layers of material including a first layer and a second layer, wherein laying down a layer, for each of the at least two layers of material, comprises (i) extruding a first material through first and second areas of a nozzle head;
- and (ii) feeding a second material through a tube of the nozzle head, wherein the second material forms an internal structure to the first material, the internal structure being situated in more than one layer such that the internal structure formed laying down the first layer is situated in both the first layer and the second layer;
- wherein laying down a layer further comprises dispensing a reinforcing material as the nozzle head is moved, such that the reinforcing material is wider than the width of the layer of material being laid down by the nozzle head, so that the reinforcing material extends beyond the width of the material being laid down;
- wherein the method further comprises driving the reinforcing material into opposing layers.
