A sintered part has at least one base with a first end face which faces in a first axial direction and a second end face which faces in a second axial direction. The end faces are produced in a press for producing a green body (which is subsequently sintered to form the sintered part) by applying at least one punch which can be moved along the axial directions. The sintered part has an elevation extending from the first end face towards one end at least in the axial direction over a first height, and the elevation has a first width extending transversely to the axial direction in a radial direction and at least some portions of which are smaller than 0.8 millimeters, wherein at least some portions of the sintered part have a first density along the first width, said density equaling at least 87% of the full material density.

A cold plate having a copper base plate and a plurality of fins on the copper base plate. The fins are porous and made by 3D printing a copper-silver alloy on the copper base plate. Alternatively, the fins can be 3D printed and then adhered to the copper base plate with a brazing material. The copper base plate is placed on electronics to be cooled, such as a chip package, using a thermal interface material. An optional manifold can be placed on the copper base plate for circulating a coolant across the fins.

A method of manufacturing a structural component for a vehicle, in particular an aircraft or spacecraft, includes additively manufacturing a reinforcing plate of a metal material having on a joining surface a plurality of joining arms projecting from the joining surface; and joining the reinforcing plate at the joining surface to a structural element to form the structural component by inserting the joining arms into the structural element such that the joining arms permanently hold the structural element together with the reinforcing plate.
