Abstract
An additive manufacturing apparatus for forming a part includes a support, a first dispenser to deliver a layer of first particles on a support or an underlying layer on the support, a second dispenser to deliver second particles onto the layer of first particles such that the second particles infiltrate into the layer of first particles, an energy source to fuse the first particle and second particles to form a fused layer of the part, and a controller coupled to the first dispenser, second dispenser and energy source.
Claims15
An additive manufacturing apparatus for forming a part, comprising:
- a support;
- a powder delivery system including
- a first dispenser having a first aperture positioned above the support to deliver first particles over the support;
- a second dispenser having a second aperture positioned above the support and spaced from the first dispenser along a first axis to deliver second particles over the support;
- a third dispenser having a third aperture positioned above the support and spaced from the first dispenser along the first axis to deliver second particles over the support, the third dispenser positioned on an opposite side of the second dispenser from the first dispenser, and
- an actuator to move the powder delivery system including the first dispenser, the second dispenser, and the third dispenser laterally along the first axis parallel to a surface of the support such that the first aperture, the second aperture, and the third dispenser move across the surface of the support together;
- an energy source to fuse the first particle and second particles to form a fused layer of the part;
- and
- a controller coupled to the first dispenser, second dispenser, third dispenser, actuator and energy source, the controller configured to alternately i) cause the actuator to move the first dispenser, second dispenser and third dispenser along the first axis in a first direction and to cause the first dispenser to deliver the first particles in a first layer and the second dispenser to deliver the second particles onto the first layer of first particles simultaneous with motion in the first direction such that the second particles infiltrate into the first layer of first particles, and ii) cause the actuator to move the first dispenser, second dispenser and third dispenser along the first axis in a second direction opposite to the first direction and to cause the first dispenser to deliver the first particles in a second layer and the third dispenser to deliver the second particles onto the second layer of first particles simultaneous with motion in the second direction such that the second particles infiltrate into the second layer of first particles.

An additive manufacturing apparatus for forming a part, comprising:
- a support;
- a powder delivery system including
- a first dispenser having a first aperture positioned above the support to deliver a layer of first particles on a support or an underlying layer on the support, wherein the first dispenser comprises a first roller having the first aperture integrated therein, and
- a second dispenser having a second aperture positioned above the support and spaced from the first dispenser along a first axis to deliver second particles onto the layer of first particles such that the second particles infiltrate into the layer of first particles, wherein the second dispenser comprises a second roller having the second aperture integrated therein, and
- an actuator to move the powder delivery system including the first dispenser and the second dispenser laterally along the first axis parallel to a surface of the support such that the first aperture and the second aperture move across the surface of the support together while simultaneously delivering the first particles and the second particles, respectively;
- an energy source to fuse the first particles and second particles to form a fused layer of the part;
- and
- a controller coupled to the first dispenser, second dispenser and energy source.
