Additive manufacturing system having laser and dispenser on common support
First Claim
1. An additive manufacturing system, comprising:
- a platen having a top surface to support an object being manufactured;
a support structure;
a dispenser to deliver a plurality of successive layers of a powder on the platen, the dispenser configured to deliver the powder on the platen simultaneously in a linear region that extends and is elongated along a first axis;
an actuator coupled to the support structure to move the support structure along a second axis parallel to the top surface and perpendicular to the first axis; and
an energy source configured to fuse at least a portion of the powder on the platen;
wherein the dispenser and energy source are secured to the support structure such that the dispenser and energy source move as a single unit with the support structure over the platen along the second axis and such that the linear region sweeps along the second axis to deposit the powder along a swath over the platen to form a layer of powder.

Abstract
An additive manufacturing system includes a platen to support an object being manufactured, a dispenser to deliver a plurality of successive layers of a powder over the platen, and energy source configured to fuse at least a portion of the powder. The dispenser is configured to deliver the powder in a linear region that extends along a first axis. The dispenser and actuator are supported by a support structure, and the actuator is coupled to the support structure to move the support structure along a second axis perpendicular to the first axis such that the dispenser and energy source move as a single unit with the support structure and the linear region sweeps along the second axis to deposit the powder along a swath over the platen to form a layer of powder.

15. A method of additive manufacturing, comprising:
-
flowing a powder from a dispenser in a linear region on a platen, the linear region extending along a first axis, the dispenser supported by a support structure; selectively heating, by an energy source supported by the support structure, the powder to a temperature sufficient to cause the powder to fuse; moving the support structure along a second axis perpendicular to the first axis and parallel to a top surface of the platen such that the dispenser and energy source move as a single unit with the support structure over the platen along the second axis and such that the linear region sweeps along the second axis to deposit the powder along a swath over the platen to form a layer of powder. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
