The present invention provides a method of joining dissimilar materials, particularly a non-ferrous component to a ferrous component to form an assembly. In an overlapping configuration, the parts are held together under a clamping force while a self-piercing rivet is driven through the assembly by a welding electrode. The rivet pierces and passes through the non-ferrous component and then at least into contact with the ferrous component to thereby form a mechanical interlock. An electrical current is then applied to this mechanical retention to melt a portion of the rivet as well as a portion of the ferrous metal in the joining region. The flow of electrical current is then stopped after several welding cycles where the now melted material is allowed to solidify upon cooling, thereby forming a weld.

A method of manufacturing a medical implant comprising a radiopaque marker is described. The method comprises manufacturing a medical implant using stereolithography, wherein the medical implant has an external surface that delimits an opening to a channel. A curable mixture of a biocompatible polymer and a radiopaque material is then inserted into the channel while in a liquid state and cured in the channel so that it solidifies in the channel.The combination of an implant manufactured by stereolithography and a radiopaque marker which is inserted into the channel in a liquid state enables complex internal structures to be formed in the implant for the radiopaque marker and for the marker to take on those complex forms more easily. This allows a better visualisation of the marker under X-Ray or other medical imaging technique.
