Abstract
One variation of a method for fusing and annealing powered material within an apparatus for manufacturing includes: depositing a layer of powdered material across a build platform; at a first time, projecting a first energy beam of a first power density onto an area of the layer of powdered material; and at a second time succeeding the first time, projecting a second energy beam of a second power density less than the first power density onto the area.
Claims21
A method for fusing and annealing powered material within an apparatus for manufacturing, the method comprising:
- depositing a layer of powdered material across a build platform;
- at a first time, projecting a first energy beam of a first power density onto an area of the layer of powdered material;
- and
- at a second time succeeding the first time, projecting a second energy beam of a second power density less than the first power density onto the area.
A method for fusing and annealing powered material within an apparatus for manufacturing, the method comprising:
- depositing a layer of powdered material across a build platform;
- projecting a first energy beam along a first direction across the layer of powdered material, the first energy beam of a first power density at the layer of powdered material;
- projecting a second energy beam across the layer of powdered material, the second energy beam trailing the first energy beam and of a second power density at the layer of powdered material greater than the first power density;
- and
- projecting a third energy beam across the layer of powdered material, the third energy beam trailing the first energy beam and the second energy beam and of a third power density at the layer of powdered material less than the first power density.
