Dispensing print agent from print bars

1 . An additive manufacturing apparatus comprising:

first and second print bars that each have first and second print dies, wherein:

the second die of the first print bar is closer to the second print bar than the first die of the first print bar is,

the first die of the second print bar is closer to the first print bar than the second die of the second print bar is, and

the first and second dies of the first and second print bars partially overlap in a direction transverse to direction of travel along a print bar movement axis in an overlap region;

a processor; and

a memory storing instructions executable by the processor to perform processing comprising:

determining a pattern of a first print agent to be applied to a layer of build material;

dispensing, in the overlap region, a first portion of the determined pattern of the first print agent onto the layer of build material from the first die of the first print bar; and

dispensing, in the overlap region, a second portion of the determined pattern onto the layer of build material from the second die of the second print bar.

2 . The additive manufacturing apparatus of claim 1 , wherein the first and second portions of the determined pattern of the first print agent are respectively dispensed in the overlap region by the first die of the first print bar and the second die of the second print bar according to taper weaving masks.

3 . The additive manufacturing apparatus of claim 1 , wherein the processing further comprises not dispensing the first print agent in the overlap region from the second die of the first print bar nor from the first die of the second print bar.

4 . The additive manufacturing apparatus of claim 1 , wherein the processing further comprises, in the overlap region, a second print agent from the second die of the first print bar and from the first die of the second print bar.

5 . The additive manufacturing apparatus of claim 4 , wherein the second print agent is dispensed in the overlap region by the second die of the first print bar and from the first die of the second print bar according to taper weaving masks.

6 . The additive manufacturing apparatus of claim 1 , wherein the processing further comprises:

forming successive layers of build material;

dispensing the first print agent onto each layer according to the pattern, wherein the pattern is derived from data modeling at least one object to be generated; and

applying energy to the layer to cause at least one of coalescence or binding of the build material.

7 . A non-transitory machine-readable medium storing instructions executable by a processor to perform processing comprising:

determining a pattern of a first print agent to be applied to a layer of build material by an additive manufacturing apparatus within first and second print bars that each have first and second dies, wherein

the second die of the first print bar is closer to the second print bar than the first die of the first print bar is,

the first die of the second print bar is closer to the first print bar than the second die of the second print bar is, and

the first and second dies of the first and second print bars partially overlap in a direction transverse to direction of travel along a print bar movement axis in an overlap region;

dispensing, in the overlap region, a first portion of the determined pattern of the first print agent onto the layer of build material from the first die of the first print bar; and

dispensing, in the overlap region, a second portion of the determined pattern onto the layer of build material from the second die of the second print bar.

8 . The non-transitory machine-readable medium of claim 7 , wherein the first and second portions of the determined pattern of the first print agent are respectively dispensed in the overlap region by the first die of the first print bar and the second die of the second print bar according to taper weaving masks.

9 . The non-transitory machine-readable medium of claim 7 , wherein the processing further comprises not dispensing the first print agent in the overlap region from the second die of the first print bar nor from the first die of the second print bar.

10 . The non-transitory machine-readable medium of claim 7 , wherein the processing further comprises, in the overlap region, a second print agent from the second die of the first print bar and from the first die of the second print bar.

11 . The non-transitory machine-readable medium of claim 10 , wherein the second print agent is dispensed in the overlap region by the second die of the first print bar and from the first die of the second print bar according to taper weaving masks.

12 . The non-transitory machine-readable medium of claim 7 , wherein the processing further comprises:

forming successive layers of build material;

dispensing the first print agent onto each layer according to the pattern, wherein the pattern is derived from data modeling at least one object to be generated; and

applying energy to the layer to cause at least one of coalescence or binding of the build material.
