  • Publication number: 20210291416
    Abstract: A light assembly and method of forming light assemblies includes a flexible light layer, a thermoplastic housing, and an IMC layer. The flexible light layer has a flexible substrate, a printed circuit, and a plurality of LEDs extending outward from the flexible substrate. The IMC layer is formed opposite the flexible light layer from the thermoplastic housing and covers the LEDs. Forming may include placing the flexible light layer within a mold cavity, injecting the thermoplastic structure on one side of the flexible light layer, and injecting the IMC layer on the opposite side of the flexible light layer from the thermoplastic structure. Injecting the thermoplastic structure into the mold cavity may change the shape of the flexible light layer. Datum features of the flexible light layer may align the thermoplastic structure relative to the datum features.

The thermal layer may be attached to the heat sink layer, be semi-transparent, and configured to reduce an intensity of the thermal load reaching the reflective display. The warming layer may be attached to the second side, be transparent, and configured to heat the reflective display in response to an electric current. The control circuit may be configured to control the electric current to the warming layer based on a temperature signal indicating a temperature of the semi-transparent sign.

  • Publication number: 20190022961
    Abstract: A method for fused filament fabrication of a thermoplastic part includes: mixing an additive material that is electrically conductive with a thermoplastic material; forming a filament made of materials that include the thermoplastic material mixed with the additive material: passing the filament through an alternating magnetic field such that the additive material is heated by the alternating magnetic field and thus heats the thermoplastic material of the filament; and depositing the materials of the filament on a previously deposited layer of the part to form a newly deposited layer of the part. The thermoplastic material in the newly deposited layer is sufficiently heated such that the thermoplastic material of the newly deposited layer fuses with the thermoplastic material of the previously deposited layer. The method may include: extruding the materials of the filament through a nozzle; and continuing to deposit the materials of the filament until the part is manufactured.
