Abstract: In general, in various embodiments, the present disclosure is directed systems and methods for producing a porous surface from a solid piece of polymer. In particular, the present disclosure is directed to systems that include a track assembly, mold assembly, press assembly, and methods for using the same for producing a porous surface from a solid piece of polymer. In some embodiments, the present systems and methods are directed to processing a polymer at a temperature below a melting point of the polymer to produce a solid piece of polymer with an integrated a porous surface.

Abstract: A method for making a polymer with a porous layer from a solid piece of polymer is disclosed. In various embodiments, the method includes heating a surface of a solid piece of polymer to a processing temperature below a melting point of the polymer and holding the processing temperature while displacing a porogen layer through the surface of the polymer to create a matrix layer of the solid polymer body comprising the polymer and the porogen layer. In at least one embodiment, the method also includes removing at least a portion of the layer of porogen from the matrix layer to create a porous layer of the solid piece of polymer.

Abstract: Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. The polymeric material is then at least partially solidified. The soluble material is then removed such as by solvent washing to thereby produce desired porous articles. Also described are systems for performing the various processes.
