A method of manufacturing a catheter tip by electroplating a conductive material over an insert comprising a negative to a domelike shape thereby forming a shape of the catheter tip comprising a dome with the domelike shape, selectively positioning a plurality of irrigation holes between outer and inner surfaces of the catheter tip, removing the insert thereby leaving the catheter tip and the plurality of irrigation holes, and electropolishing the catheter tip. In other examples, the insert is not removed and instead the step of electroplating causes the insert to be encapsulated with the conductive material thereby forming the catheter tip.

A gas turbine engine guide vane heat exchanger has guide vane heat exchanger including electroformed fluid channels in electroformed heat exchanger tubes or a heat exchanger core disposed within airfoil. Non-flammable heat conducting liquid or non-metallic foam may fill space between tubes or core and airfoil. Fluid circuit may include channels within electroformed heat exchanger tubes or the heat exchanger core and extend from inlet manifold to outlet manifold for directing fluid or oil through channels and include fluid or oil supply inlet connected to inlet manifold for receiving the fluid or oil flowed into inlet manifold and a fluid or oil supply outlet connected to fluid or oil supply outlet for discharging fluid or oil flowed out of fluid or oil outlet manifold. Heat exchanger tubes or heat exchanger core, inlet manifold, outlet manifold, supply inlet and supply outlet may be integrally and monolithically electroformed together.

An electroformed heat exchanger suitable for use between rotating blades and seals in a stationary casing of a turbine engine. The heat exchanger comprising a non-electroformed carrier plate having a radial outer surface and a radial outer surface, an electroformed duct provided along the radial outer surface, an electroformed rail provided on the radial inner surface, and an electroformed stiffener formed by a portion of the electroformed duct and the electroformed rail.

A thin-walled metal part, and a method to fabricate such a part out of various alloys. A plurality of layers are formed, each of the layers being formed on a polymer template or on a previously formed layer. A homogenizing heat treatment is used to cause chemical elements in the layers to interdiffuse, to form a single continuous layer with a substantially uniform alloy composition.
