摘要： A printing system for producing at least one three dimensional (3D) printed part is described. The printing system includes a deposition system configured to continuously deposit a layer onto a cylinder to outwardly extend a diameter of the cylinder, wherein the layer comprises a first pattern. The printing system also includes a rotating system configured to rotate the cylinder, and a control system configured to synchronize the deposition system with the cylinder.

摘要： A method for providing high-speed three dimensional (3D) printing is provided. The method includes producing at least one three dimensional (3D) printed part. Producing the 3D part includes continuously constructing to extend outwardly a diameter of a rotating cylindrical core via continuous deposition of a layer, and defining a first pattern in the continuously deposited layer corresponding to a cross-section of the at least one 3D printed part.

摘要： A transfer system includes a transfer layer formed of a thermally switchable material that undergoes a phase change when heated. A side of the transfer layer is placed in contact with an outward-facing side of a chiplet during a transfer operation. An optical absorber material is located on at least one of the outward facing side of the chiplet or an inward facing side of the chiplet. An optical energy source is operable to apply optical energy to the optical absorber material through the transfer layer to selectively heat a region of the transfer layer that corresponds to a location of the chiplet. The region holds the chiplet when the optical energy is removed during the transfer operation. The region is subsequently heated during the transfer operation to release the chiplet.

摘要： A release layer is formed on a surface of an integrated circuit wafer. The surface is passivated and includes metal contact materials. A stress-engineered film having an intrinsic stress profile is deposited over the release layer. The stress-engineered film is patterned and the release layer is undercut etched so that a released portion of the patterned stress-engineered film is released from the surface while leaving an anchor portion fixed to the surface. The intrinsic stress profile in the stress-engineered film biases the released portion away from the surface. The released portion is placed entirely within an area defined by the metal contact material.

摘要： An apparatus includes a pressure device bonded to the surface of a structure at a bonding location. The vessel comprises an interior space within the vessel and a bonding surface. A bonding agent bonds the bonding surface of the vessel to a surface of the structure. A gas-emitting material is disposed within the interior space of the vessel and an initiator is arranged to activate the gas-emitting material. Upon activation of the gas-emitting material by the initiator, the pressure device produces a localized force that breaks the structure.

摘要： Formation of a multi-colored image in thermochromic material involves controlling operation of first, second, and third heat sources. The first heat source heats pixels of the thermochromic material to activate the pixels. The second and third heat sources are selectively controlled to heat different sets of pixels using neither, one, or both of the second and third heat sources.
