An electrical connecting structure (10) for use as a means for transmitting electrical energy between a first electrical component and a second electrical component, wherein the connecting structure (10) is formed from a number of layers (20, 30, 40, 50) arranged serially with one another, a first outer layer (20) consisting of aluminum or an aluminum alloy and a second outer layer (50) preferably consisting of aluminum or an aluminum alloy, and a third and preferably fourth layer (30, 40), specifically one or two inner layers, being provided between the outer layers (20, 50), the inner layer or inner layers (30, 40) being respectively produced by cold gas spraying.

A heating assembly includes a support member for supporting a target thereon, a diffuser layer attached to the support member, and a heater attached to the diffuser layer. The diffuser layer includes discrete diffuser segments separated by gaps. The discrete diffuser segments are made of the same material and are configured to allow a desired thermal gradient to be maintained between the discrete diffuser segments during heating of the target.

A method of treating the surface of a 3D object, comprising obtaining a digital 3D shape representation defining characteristics of the object; using a computerised device to convert the 3D shape representation into a digital 2D shape representation defining the 3D surface of the object as it if laid out flat; using the computerised device to generate a digital 2D tool path representation defining movements an applicator or removal tool would take to treat the surface of the shape defined by the 2D shape representation; using the computerised device to convert the 2D tool path representation to a digital 3D tool path representation defining movements that the applicator or removal tool will take to deposit material on, or remove it from, the surface to treat the 3D object; and using the 3D tool path representation to control the applicator tool or removal tool to treat the 3D object.
