A method of guiding an angiographic wire while delivering fluid solvent to the wire. The method incorporates a guide device comprising a housing that is mated to a base in a manner that defines an aperture for slidably receiving the angiographic wire. A plunger is disposed within the housing in a vertically adjustable manner such that the plunger has an open position, a closed position, and one or more intermediate positions relative to the housing. The angiographic wire is placed in the aperture, and the housing is mated to the base such that the wire is slidably retained in the aperture. The plunger is depressed such that a compression pad on the plunger is placed in contact with the wire, the wire being slidably retained between the compression pad and a base pad attached to the base.

A build plate may include one or more thermocouples placed on an underside of the build plate. The one or more thermocouples output temperature fluctuation to assist in monitoring for build plate separation of a product located on top of the build plate.

A guide device capable of guiding an angiographic wire while delivering fluid solvent to the wire. The guide device comprises a housing mated to a base in a manner that defines an aperture for slidably receiving the angiographic wire. The housing comprises a plunger configured for placement in an open position, a closed position, and one or more intermediate positions. The guide device comprises a port placed in fluid communication with an absorbent base pad capable of being impregnated with fluid solvent, and delivering the solvent to the surface of the angiographic wire.

A fabrication assembly comprises an apparatus that receives a composite substrate and a glass substrate having a surface with a release coating layer. A resin layer is deposited between the composite and glass substrates such that a first portion of the resin layer is positioned adjacent to a surface of the composite substrate and a second portion of the resin layer is positioned adjacent to the surface with the release coating layer to prevent aperture(s) from forming. A curing of the resin layer is conducted using electromagnetic radiation. A post-processing chamber receives the resin layer positioned between the composite substrate and the glass substrate and conducts another curing of the resin layer. The resin layer and the composite substrate are released from the glass substrate. Another deposition apparatus receives the resin layer and the composite substrate. A metallic coating is deposited to form a composite mirror object.

A radio-frequency transparent window having internal conduits for the passage of cooling fluid is configured for simulating a highly uniform thermal environment for testing a device intended for use in space. The device to be tested is placed within a chamber in which a vacuum condition is maintained by a radio-frequency transparent pressure window under a pressure seal. Within the chamber, the thermal window is positioned adjacent, but not in contact with, the pressure window. A radio frequency signal is capable of passing directly through both the thermal window and the pressure window to permit communication with the device being tested within the housing. The thermal window is not in contact with the device so there in no conduction of heat from the device. Radiant heat transfer may occur from the device to the thermal window.
