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 a mold for processing a material. The mold includes a body having a top surface and a bottom surface. A void within the body is configured to receive a porogen and a piece of thermoplastic material. The void extends in a top to bottom direction to form a non-through cavity with a cavity surface that is substantially parallel to the bottom surface of the body. A protrusion on the body extends from the cavity surface towards the top surface. The void extends at least halfway through the body towards the bottom surface. A peg is disposed on the body and shaped to matingly engage a weight via a hole within the weight.

Mold for processing of materials

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.

Method for producing porous devices

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 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.
