A wire harness includes: a harness main body. The harness main body includes a plurality of electric wires and a binding portion. The biding portion is configured to bind the plurality of electric wires. The binding portion is formed by a cured photocurable resin.

A method and/or system for forming a micro-truss structure in an essentially arbitrary shape. A mold that has a transparent portion, and having an interior volume in the desired shape, is filled with photomonomer resin. The material for the transparent portion of the mold is selected to be a material that is index-matched to the photomonomer resin. The filled mold, placed into a bath of transparent fluid index-matched to the transparent portion of the mold, and illuminated, from outside the fluid, through a photomask, with collimated light. The collimated light travels through the photomask forming beams of light that enter the transparent fluid, propagate into the mold, and form a micro-truss structure in the shape of the interior volume of the mold. The micro-truss structure may then be removed from the mold, or part or all of the mold may be left adhered to the micro-truss structure, forming covering face sheets.

A mold includes a rugged pattern layer, an inorganic sheet layer, and an elastic sheet layer. The inorganic sheet layer is formed of an inorganic material and supports the rugged pattern layer. The elastic sheet layer supports the inorganic sheet layer.

A system and method for forming a seal member onto a substrate from a material is disclosed. The system includes a mold comprising an ultraviolet transmissible material, the mold having a first portion and a second portion operatively coupled to the first portion, the first portion having a first cavity, a second cavity, and a channel extending from an outer surface of the mold to the second cavity. The first cavity has a first shape that is complementary to a first side of the substrate and the second cavity has a second shape that is complementary to the seal member. The system also includes an applicator in fluid communication with the channel, where the applicator is configured to provide the material to the second cavity through the channel, and an ultraviolet irradiation device configured to irradiate the mold with ultraviolet light to cure the material when the material is provided to the second cavity, such that the seal member is formed on the substrate.

Disclosed herein is a device (100) for making an object. The device (100) comprises a vessel (44) for receiving a radiation hardenable material (42). The device (100) comprises a fabrication platform assembly (7) comprising a fabrication platform (8) and having a first mode in which an orientation of the fabrication platform (8) is adjustable and a second mode in which the orientation of the fabrication platform (8) is fixed, and configured for positioning at the vessel (44) in the second mode to form a layer of the radiation hardenable material when so received between the fabrication platform (8) and a wall (46) of the vessel (44). The device (100) comprises a radiation source (48) arranged to illuminate the layer of radiation hardenable material when so formed to form one of a plurality of layers of the object. The device (100) comprises a guide (28) configured to receive the fabrication platform assembly (7) in the first mode and orientate the fabrication platform (8) when so received with respect to the guide (28). Also disclosed herein is a method for making an object.

The present disclosure provides a transferring method and a repeatable transferring method. The transferring method includes steps of: performing surface modification treatment on a transferring surface of a transfer mold to reduce surface free energy of the transferring surface; forming a liquid material layer on the transferring surface after the surface modification treatment; curing the liquid material layer to form a solid material layer; and releasing the solid material layer from the transfer mold.

A device for lacquer transfer includes a frame, transfer roller with circumferential lateral wall, nozzle for dispensing lacquer, and hardening unit, the hardening unit formed as a UV-light unit for hardening the lacquer in a contactless way by emitting UV-light, and is within an interior space defined by the transfer roller. The lateral wall of the transfer roller is transparent for UV-light, and the hardening unit is arranged such that UV-light is emitted towards the work surface upon which the lateral wall of the transfer roller rolls, to harden the lacquer after it being transferred to the work surface. Using the device, lacquer transfer can occur from the transfer roller to the work surface more reliably. The device includes a light shield between the hardening unit and outside contact surface with at least a portion of the outside contact surface provided with lacquer is shielded from UV-light emitted from the hardening unit.

The present disclosure provides method and systems for printing a three-dimensional (3D) object. A method for 3D printing may comprise providing a mixture comprising (i) a polymeric precursor, (ii) a photoinitiator configured to initiate formation of a polymeric material from the polymeric precursor, and (iii) a photoinhibitor configured to inhibit the formation of the polymeric precursor. The method may comprise exposing the mixture to (i) a first light to cause the photoinitiator to initiate formation of the polymeric material, thereby to print the 3D object, and (ii) a second light to cause the photoinhibitor to inhibit the formation of the polymeric material. During printing of the 3D object, a ratio of (i) an energy of the second light sufficient to initiate formation of the polymeric material relative to (ii) an energy of the first light sufficient to initiate formation of the polymeric material may be greater than 1.

Methods of using and repairing seal caps as well as constructions comprising seal caps, including in some embodiments seal caps which may be useful in sealing fasteners that protrude into fuel storage cells in aircraft. In some embodiments, methods include the use of optically translucent seal cap and application of a second quantity of sealant to fill voids observed within the interior of the seal cap after cure of a first quantity of sealant.
