Abstract
A consumable filament for use in an extrusion-based additive manufacturing system, where the consumable filament comprises a first portion of a first semi-crystalline polymeric material, and a second portion of a second semi-crystalline polymeric material, and where the second semi-crystalline polymeric material has a crystallization temperature that is greater than a crystallization temperature of the first semi-crystalline polymeric material.
