An additive manufacturing apparatus includes a platform, a dispenser configured to deliver a plurality of successive layers of feed material onto the platform, at least one light source configured to generate a first light beam and a second light beam, a polygon mirror scanner, an actuator, and a galvo mirror scanner. The polygon mirror scanner is configured to receive the first light beam and reflect the first light beam towards the platform. Rotation of the first polygon mirror causes the light beam to move in a first direction along a path on a layer of feed material on the platform. The actuator is configured to cause the path to move along a second direction at a non-zero angle relative to the first direction. The galvo mirror scanner system is configured to receive the second light beam and reflect the second light beam toward the platform.

Raw material devices, systems that incorporate raw material delivery devices, and methods of supplying raw material using the raw material devices. A raw material delivery device includes a hollow body comprising a first end and a second end, the second end disposed above the first end in a system vertical direction, an inlet disposed at the first end of the hollow body, an outlet disposed at the second end of the hollow body, and a stepped passageway disposed within the hollow body between the inlet and the outlet. The stepped passageway is configured to deliver raw material via one or more steps from the inlet to the outlet.

A 3D printing apparatus is disclosed herein. The 3D printing apparatus comprises a build compartment defining a build chamber within which a 3D object is to be generated; and a non-powered platform, moveable within the build chamber, comprising a platform drive interface to engage with an external drive mechanism to cause the platform to move. The 3D printing apparatus further comprises a powder compartment located laterally adjacent to the build compartment, within which build material is to be stored for use in the generation of the 3D object. The 3D printing apparatus also comprises a locking interface to couple the 3D printing apparatus with an external hosting device.

Systems and methods of additively manufacturing passive electronic components are provided. An additive manufacturing device may deposit a material to create a passive electronic component. A sensor may continuously measure an electrical property of the passive electronic component across two electrical contacts as the material is deposited during manufacturing. The sensor may transmit the measured electrical property to a processor whereby the processor may adjust a material deposition rate of the additive manufacturing device. The continuous measurement of the electrical property and adjustment of the material deposition rate as the passive electronic component is produced allows for passive electronic components to be manufactured to a high degree of accuracy of the electrical property.

A powder spreading apparatus includes a hopper having a first end, a second end opposite from the first end, a front wall, a rear wall opposite from the front wall, and a floor. The front wall, the rear wall, the first end, the second end, and the floor define an interior. An impeller is disposed within the interior of the hopper. The impeller includes a plurality of circumferentially spaced flutes and is configured to rotate about an impeller axis that extends from the first end of the hopper to the second end of the hopper to deposit powder onto a print area. A spreader rod is coupled to the hopper and extends along a spreader rod axis parallel to the impeller axis. The spreader rod is configured to rotate about the spreader rod axis to smooth the powder as it is deposited onto the print area.
