Abstract: A printer fabricates an object from a computerized model using a fused filament fabrication process and a metallic build material. A build plate that receives the object during fabrication includes a coating of material with a low melt temperature, such as a low melt temperature solder. In particular, the material may be an alloy that can be solidified while receiving the object, and then heated into a liquid state to facilitate removal of the object after fabrication is complete at a temperature sufficiently low that the adjacent, fabricated object does not melt or deform.

Abstract: A printer fabricates an object from a build material based on a computerized model and a fused filament fabrication process. A nozzle for depositing the build material has an interior diameter approaching an outer diameter of build material fed to the nozzle in order to reduce extrusion and resistance forces imposed by the nozzle during deposition, while adequately constraining a planar position of the build material for accurate material deposition in a computer-controlled fabrication process.

Abstract: Devices, systems, and methods are directed to switching between pneumatically actuated ejection and electrically actuated ejection of liquid metal from a nozzle moving along a controlled three-dimensional pattern to fabricate a three-dimensional object. Electrically actuated ejection can be useful, for example, for delivering discrete droplets in areas of the object requiring a high degree of accuracy. Pneumatic ejection can be useful, for example, for delivering a stream of liquid metal from the nozzle to provide liquid metal rapidly to areas of the object that require less accuracy (e.g., an inner portion of the object). Accordingly, switching between pneumatically actuated ejection and electrically actuated ejection can facilitate accurate and rapid production of parts through additive manufacturing.

Abstract: The problem addressed by the present invention is providing a method for producing microparticles. At least two fluids to be processed, a raw material fluid that contains a raw material and a processing fluid that contains a substance for processing the raw material are mixed in a thin film fluid formed between at least two surfaces for processing that are disposed so as to face each other, that can approach and separate from each other and at least one of which rotates relative to the other, and microparticles of the raw material that is processed are obtained. At this time, the proportion of the microparticles of the raw material which has been processed that coalesces with each other is controlled by controlling the circumferential speed of the rotation in a confluence section in which the raw material fluid and processing fluid flow together.

Abstract: Embodiments of the invention generally include apparatus and methods for depositing nanowires in a predetermined pattern during an electrospinning process. An apparatus includes a nozzle for containing and ejecting a deposition material, and a voltage source coupled to the nozzle to eject the deposition material. One or more electric field shaping devices are positioned to shape the electric field adjacent to a substrate to control the trajectory of the ejected deposition material. The electric field shaping device converges an electric field at a point near the surface of the substrate to accurately deposit the deposition material on the substrate in a predetermined pattern. The methods include applying a voltage to a nozzle to eject an electrically-charged deposition material towards a substrate, and shaping one or more electric fields to control the trajectory of the electrically-charged deposition material. The deposition material is then deposited on the substrate in a predetermined pattern.
