Abstract
A method of forming a three-dimensional body from a mixture, wherein the mixture can comprise dispersed solid polymeric particles and a curable binder. In a particular embodiment the solid polymeric particles can be fluoropolymeric particles. The method can include at least partial removal of the cured binder and sintering, to obtain a sintered polymeric three-dimensional body. In one embodiment, the sintered three-dimensional body can be PTFE.
