ABSTRACT:
The present invention is directed to apparatus and methods for forming open-cell porous mold forms to mold porous devices having substantially continuously interconnected pores. The mold form is made from selected material comprising particles having predetermined sizes and shapes which is capable of forming a stable mold form under selected conditions. The particles are treated such that the particles are manipulable into a mass of continuously interconnected particles defining continuously interconnected pores and connecting interstices within the mass. The formed mass is made into a predetermined shape and solidified to form a mold form.
