An assembly and method of producing one or a plurality of reservoirs or wells having a bulge when viewed in cross-section, in a foam material, with a laser processing system. The assembly comprises a housing configured to receive a galvo therein, and wherein the first housing has exterior surface topography comprising a plurality of apertures a compression mechanism comprising an exterior surface topography having a plurality of surface protrusions thereon for compressing the material passing over at least one of the plurality of surface protrusions and wherein the housing and the compression mechanism are spaced apart providing a gap there between for receiving a web of the material therein. Laser processing comprises compressing the material around a target area on a first surface of the material and concurrently directing a focal point of a laser beam to the target area to produce the reservoirs.
