METHOD AND SYSTEM FOR MAKING POROUS ARTICLES

A method of forming a porous article comprises forming a packed region of a soluble particulate material with a plurality of voids. A flowable polymeric material contacts at least a portion of the packed region so that it becomes disposed in at least a portion of the voids. The polymeric material is...

More Information
Summary:A method of forming a porous article comprises forming a packed region of a soluble particulate material with a plurality of voids. A flowable polymeric material contacts at least a portion of the packed region so that it becomes disposed in at least a portion of the voids. The polymeric material is at least partially solidified to form an intermediate composite material. At least a portion of the soluble particulate material is removed from the intermediate composite to form a porous article.
