A method of forming an implant having a porous tissue ingrowth structure and a bearing support structure. The method includes depositing a first layer of a metal powder onto a substrate, scanning a laser beam over the powder so as to sinter the metal powder at predetermined locations, depositing at least one layer of the metal powder onto the first layer and repeating the scanning of the laser beam.

The present document discloses a tool or tool part for use in a process of molding a product from a pulp slurry. The tool or tool part comprises a self-supporting tool wall portion having a product face, for contacting the product, and a back face on the other side of the wall relative to the product face. The tool wall portion presenting pores, which are provided by a plurality of channels extending through the tool wall portion, from the product face to the back face. The channels are straight or curved with no more than one point of inflection.

A firearms suppressor incorporates one or more thermal energy absorbing elements, or thermal energy sponges, fabricated from porous metal. These elements efficiently absorb heat from the propellant gas generated when the firearm is discharged, thus reducing its pressure and the blast noise it creates. The thermal energy absorbing elements are manufactured from porous metal, a material which, due to its high efficiency in absorbing thermal energy, provides a unique solution to designing smaller, lighter, modular, more efficient and less expensive to manufacture firearm suppressors. In addition, as a result of the relationship described in the Darcy-Forchheimer equation, these porous metal elements provide the suppressor with an intrinsic, self-regulating capability, thus allowing the suppressor's use with a variety of different cartridges and different calibers with little to no change to a baseline design.
