Abstract
Multiple processes for preparing porous articles are described. The porous articles can be in a wide array of shapes and configurations. The methods include providing a soluble material in particulate form and forming a packed region from the material. The methods also include contacting a flowable polymeric material with the packed region such that the polymeric material is disposed in voids in the packed region. Also described are systems for performing the various processes.
