Abstract: An additive manufacturing system includes a laser device, a build plate, and a scanning device. The laser device is configured to generate a laser beam with a variable intensity. The build plate is configured to support a powdered build material. The scanning device is configured to selectively direct the laser beam across the powdered build material to generate a melt pool on the build plate. The scanning device is configured to oscillate a spatial position of the laser beam while the laser device is configured to simultaneously modulate the intensity of the laser beam to thermally control the melt pool.

Abstract: A method of binder jet printing a part includes depositing a layer of a powder on a working surface and selectively printing a binder solution comprising a binder into the layer of powder in a first pattern to generate a printed layer. The pattern is representative of a structure of a layer of the part. The method also includes selectively printing a channel support agent solution comprising a channel support agent into the layer of powder to generate a green body. The channel support agent is selectively printed in a second pattern representative of an internal channel of the part. The method further includes heating the green body part above a first temperature to remove the binder and generate a brown body part and heating the brown body part above a second temperature to sinter the powder to generate the part having the internal channel generated from removal of the channel support agent.

Abstract: A gradient coil comprises a curved conductor, which is tubular and has a general spiral shape. The curved conductor is formed by a process comprising depositing at least one non-conductive material layer by layer to form a substrate, and coating at least a portion of a surface of the substrate with a conductive material. The substrate has a shape matching with the general spiral shape of the curved conductor. Embodiments of the present disclosure further refer to a method for manufacturing the gradient coil.
