Claim 0:
1. A method for generating a three-dimensional (3D) object, comprising:
(a) providing adjacent to a build surface a resin comprising (i) a binder configured to decompose at a first temperature, (ii) a polymeric precursor configured to form a polymeric material, wherein said polymeric material is configured to decompose at a second temperature that is greater than said first temperature, and (iii) a plurality of particles;
(b) using said resin to generate a green part corresponding to said 3D object, wherein said green part comprises said binder, said polymeric material, and said plurality of particles;
(c) heating said green part at said first temperature to decompose at least a portion of said binder and generate one or more pores in said green part, which green part comprises said plurality of particles and said polymeric material, wherein said first temperature is from about 150 degrees Celsius to about 350 degrees Celsius, and wherein said heating at said first temperature does not decompose said polymeric material; and
(d) subsequent to (c), heating said green part at or above said second temperature to decompose at least a portion of said polymeric material, thereby generating said 3D object comprising said plurality of particles.
