    Abstract: A material delivery device for an additive manufacturing device (AMD) adapted for manufacturing objects through deposition of additive material over a build surface. The material delivery device comprises an inner funnel having a large aperture and a small aperture whereby the additive material is guided from the large aperture to the small aperture; wherein the inner funnel is electrically conductive and, upon applying an electrical current to the inner funnel, heat is generated thereby heating the additive material travelling in the inner funnel.

    Abstract: An additive manufacturing system (10) is disclosed for use in fabricating a composite structure (12). The additive manufacturing system may include a print head (16) configured to discharge a continuous reinforcement that is at least partially wetted with a matrix, and a support (14) configured to move the print head in at least one dimension during discharge. The additive manufacturing system may also include a cutting mechanism (30) connected to at least one of the print head and the support. The cutting mechanism may be configured to selectively sever the continuous reinforcement from the print head. The cutting mechanism may include a cutting implement (32), a first actuator (64) configured to move the cutting implement from a stowed position to a deployed position, and a second actuator (48) configured to engage the cutting implement with the continuous reinforcement.

    Abstract: An in-situ monitoring device for selective laser melting (SLM) additive manufacturing may include at least one coherent electromagnetic wave source to produce a detection beam, an interferometer interposed between the electromagnetic wave source and a target detection area, a photodetector to detect displacement measuring interference between electromagnetic waves from the electromagnetic wave source and reflected electromagnetic waves from the target detection area through the interferometer, and control logic to cause the detection beam to follow a print path of a material forming laser at a distance behind the material forming laser. The detection beam is placed on a laser-melted and at least partially solidified portion of a layer of a three-dimensional (3D) object formed by the material forming laser.

    Abstract: 3-D printing batch analysis is disclosed. A disclosed example apparatus includes a processor to generate a plurality of batches, wherein each of the batches represent an arrangement of a plurality of parts to be printed in a volume, discretize the batches into slices, and determine risk values of the slices based on the respective geometric primitives. The processor is to also determine aggregate risk values corresponding to the batches based on the risk values of the slices of the respective batches, and select a batch of the plurality of batches based on the aggregate risk values. The example apparatus also includes a printer to print the selected batch in the volume.
