Abstract: A process for forming metal components of controlled porosity by welding, in which a predetermined amount of metal elements (50) of oblong shape is introduced into a mold (10) in which it is distributed isotropically. The metal elements are then subjected to increasing pressure (P) until the component has its final shape. The walls of the mold are then held in position and an electric current (I) flows through the metal elements and welds them together by local melting at the points of contact due to the Joule effect.

Abstract: At least one hollow zone is formed in a stack of at least one upper layer and one lower layer. The upper layer is patterned to form at least a first hollow region passing through said upper layer. The first hollow region is extended by a second hollow region formed in the lower layer by etching through an etching mask formed on the patterned upper layer. The etching mask is formed by a resin layer, positively photosensitive to an optic radiation of a predetermined wavelength, exposed to the said optic radiation through the stack and developed. The lower and upper layers of the stack are respectively transparent and opaque to said predetermined wavelength so that the patterned upper layer acts as exposure mask for the resin layer.
