Abstract
Official abstract text for this publication.
Additive manufacturing methods for fabricating a fiber-reinforced composite objects include providing at least a first layer of powder material, disposing a fiber material adjacent the at least first layer of powder material to form a fiber reinforcement layer, and applying a laser energy to the at least first layer of powder material so as to fuse the powder material into at least a first laser fused material layer adjacent the fiber reinforcement layer of the fiber-reinforced composite object.
First claim
Opening claim text (preview).
What is claimed is: 1. An additive manufacturing method for fabricating a fiber reinforced composite object, the additive manufacturing method comprising: providing at least a first layer of powder material; disposing a fiber material adjacent the at least first layer of powder material to form a fiber reinforcement layer; and, applying a laser energy to the at least first layer of powder material so as to fuse the powder material into at least a first laser fused material layer adjacent the fiber reinforcement layer of the fiber-reinforced composite object. 2. The additive manufacturing method of claim 1 , further comprising: providing at least a second layer of powder material; and, applying a laser energy to the at least second layer of powder material so as to fuse the powder material into at least a second laser fused material layer of the fiber reinforced composite object. 3. The additive manufacturing method of claim 2 , further comprising disposing an additional fiber material adjacent the at least second layer of powder material to form an additional fiber reinforcement layer. 4. The additive manufacturing method of claim 1 , wherein the powder material comprises a cobalt-chrome alloy. 5. The additive manufacturing method of claim 1 , wherein the fiber material comprises fiber. 6. The additive manufacturing method of claim 1 , wherein the fiber material comprises hollow tubes. 7. The additive manufacturing method of claim 1 , wherein applying the laser energy to the at least first layer of powder material comprises a plurality of passes of the laser energy. 8. The additive manufacturing method of claim 1 , wherein a diameter of the fiber material is less than or equal to a build layer thickness of the powder material.
