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 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.
