Abstract
A polymer material suitable for three-dimensional printing that may include at least one of polyether block amide, thermoplastic polyeurothane, and thermoplastic olefin. The polymer is formed through chemical precipitation forming a precipitated pulverulent polymer which possesses increased operating window characteristics selected from the group consisting at least one of a wider than typical range between and among the melting and recrystallization temperatures, a larger enthalpy upon melting, and a low volumetric change during recrystallization.
