1. A method for forming a porous three-dimensional (3-D) object, comprising:
- creating a mold from a negative replica of the 3-D object, the 3-D object having a first size and at least one predetermined feature;
casting a flowable material at least one of into or onto the mold; and
forming pores of at least one of a second size or a third size in the flowable material, thereby forming the porous 3-D object.

Abstract
A method for forming a porous three-dimensional (3-D) object includes creating a mold from a negative replica of the 3-D object, the 3-D object having a first size and at least one predetermined feature, and then casting a flowable material into and/or onto the mold. The method further includes forming pores of a second size and/or a third size in the flowable material, thereby forming the porous 3-D object.

15. A porous three-dimensional (3-D) object, comprising:
-
a solidified flowable material having a first size and at least one predetermined feature defined by a mold having a negative replica of the three-dimensional object; and
a plurality of pores defined throughout the solidified flowable material, at least some of the plurality of pores having a second size, and at least some other of the plurality of pores having a third size. - View Dependent Claims (16, 17, 18, 19, 20)

21. A method of forming a 3-D object, comprising:
-
designing or obtaining a 3-D image of the 3-D object, the 3-D object having a first size and at least one predetermined feature;
creating a mold from a negative replica of the 3-D image;
casting a flowable material at least one of into or onto the mold;
forming pores of at least one of a second size or a third size in the flowable material, thereby forming the porous 3-D object; and
removing the mold from the porous 3-D object. - View Dependent Claims (22, 23, 24, 25, 26, 27, 28, 29, 30)
