A method of forming cured microparticles includes providing a poly(glycerol sebacate) resin in an uncured state. The method also includes forming the composition into a plurality of uncured microparticles and curing the uncured microparticles to form the plurality of cured microparticles. The uncured microparticles are free of a photo-induced crosslinker. A method of forming a scaffold includes providing microparticles including poly(glycerol sebacate) in a three-dimensional arrangement. The method also includes stimulating the microparticles in the three-dimensional arrangement to sinter the microparticles, thereby forming the scaffold having a plurality of pores. A scaffold is formed of a plurality of microparticles including a poly(glycerol sebacate) thermoset resin in a three-dimensional arrangement. The scaffold has a plurality of pores.
