Abstract
An additive manufacturing system may include a fluid ejector. The fluid ejector may be movable across a build material distributor at a maximum speed of less than or equal to 40 inches per second. The fluid ejector may include a nozzle having a non-circular bore.
Claims20
An additive manufacturing system comprising:
- a build material distributor to distribute build material in a build area of the system;
- a fluid ejector movable across the build area at a maximum speed of less than or equal to 40 inches per second, the fluid ejector comprising a nozzle having a non-circular bore.
A fluid ejector for an additive manufacturing system, the fluid ejector comprising:
- an ejection chamber;
- a fluid actuator adjacent the ejection chamber;
- and
- a nozzle along the ejection chamber, the nozzle comprising a plurality of bores through which fluid is to be concurrently driven by the fluid actuator.
1 more element
A fluid ejector for an additive manufacturing system, the fluid ejector comprising:
- an ejection chamber having a port having a first major dimension;
- a nozzle extending from the ejection chamber;
- a fluid actuator adjacent the ejection chamber;
- an inlet leading to the port and wider than the port;
- and
- a pillar within the inlet to form a passage between the pillar and a side of the inlet, the passage having a second major dimension greater than the first major dimension.
3 more elements
An additive manufacturing system comprising:
- a build material distributor to distribute build material in a build area of the system;
- a fluid ejector movable across the build area to selectively eject a fluid agent into build material in the build area to form a cross-section of an object being built from the build material, the fluid ejector comprising a nozzle having a non-circular bore or multiple bores.
