Abstract
In one example in accordance with the present disclosure, an additive manufacturing system is described. The additive manufacturing system includes a build material distributor to deposit layers of powder build material on a bed and an agent distribution system to deposit an agent on a layer of powder build material in a pattern to form a slice of a three-dimensional object. The additive manufacturing system also includes an energy delivery system to generate a line-shaped beam of energy to selectively join build material particles with the agent deposited thereon. The line-shaped beam of energy spans a width of the bed. The additive manufacturing system also includes a scanning carriage to hold the energy delivery system and move the line-shaped beam of energy across the bed.
Claims15
An additive manufacturing system, comprising:
- a build material distributor to deposit layers of powder build material on a bed;
- an agent distribution system to deposit an agent on a layer of powder build material in a pattem to form a slice of a three-dimensional object;
- an energy delivery system to generate a line-shaped beam of energy to selectively join build material particles with the agent deposited thereon, wherein the line-shaped beam of energy spans a width of the bed;
- and
- a scanning carriage to hold the energy delivery system and move the line-shaped beam of energy across the bed.
A method, comprising:
- depositing a layer of build material on a bed;
- depositing an agent across the layer of build material in a pattern to form a slice of a three-dimensional object;
- and
- scanning the line-shaped energy beam across the bed to selectively join build material particles with agent deposited thereon.
An additive manufacturing system, comprising:
- a build material distributor to deposit layers of powder build material on a bed;
- an agent distribution system to deposit an agent on a layer of powder build material in a pattem to form a slice of a three-dimensional object;
- an energy delivery system to selectively join build material particles with agent deposited thereon, the energy delivery system comprising:
- an array of lasers;
- a collimating lens per laser connected via a fiber-optic cable to a respective laser;
- a Powell lens per collimating lens to alter a shape of an incoming circular energy beam to a line-shaped energy beam to span a width of the bed;
- and
- a scanning carriage to traverse across the bed, wherein the collimating lens and Powell lens are disposed on the scanning carriage.
