Abstract: A method of heating thermoplastic filament in additive manufacturing systems, such as 3D printing systems. In accordance with the illustrative embodiment of the present invention, the temporal rate dE/dt at which heat dE is added to a portion of a segment of filament is a function of the temporal rate dm/dt at which the mass dm of the portion of the segment of filament is deposited. In particular, the temporal rate dE/dt at which heat dE is added to a portion of a segment of filament is a non-linear function of the temporal rate dm/dt .

Abstract: The present disclosure provides methods for additive manufacturing of a three- dimensional (3D) object, comprising preheating a feed comprising a polymer material to a temperature in excess of a glass transition temperature and below a melting point of the polymer material. The preheating may occur at a first location in an additive manufacturing apparatus. Next, the polymer material may be melted at a second location that is spatially distinct from the first location.
