Abstract: Multi-part filaments for additive manufacturing comprise an elongate filament body. The elongate filament body comprises a first body part extending longitudinally along the elongate filament body, and a second body part extending longitudinally along the elongate filament body. The first body part comprises a first material, and the second body part comprises a second material. One of the first body part and the second body part is more rigid than the other of the first body part and the second body part and is sufficiently rigid to print self-supporting structures from the multi-part filament.

Abstract: Systems for thermal control of additive manufacturing comprise a build volume within which a part is additively manufactured; a heat source positioned relative to the build volume and configured to actively deliver heat to discrete sections of the part as it is being additively manufactured; and a controller operatively coupled to the heat source and configured to direct delivery of heat from the heat source to discrete sections of the part as it is being additively manufactured to impart desired physical properties to the part.
