Abstract: Disclosed herein are methods that includes using a water-degradable (e.g., autoclavable) support material together with a high-heat build material (e.g., polyetherimide or PEI). When the support material is autoclaved for a period of time, the support material becomes brittle and then disintegrates into powder and therefore can be removed from the model or build material, leaving behind a part formed from the model material that includes features (e.g., cavities, channels, etc.) formerly occupied by the support material.

Abstract: A method of forming a three dimensional object comprising: moving a first polymer material (30) through a first feed channel (38) of an extrusion die (10) having multiple feed channels; moving a second material (40) through a second feed channel (38) of the extrusion die, wherein the second material comprises a solvent, a release agent, a coating or a second polymer material; forming a multilayered extrudate (20) along an extrusion axis, wherein the multilayered extrudate comprises the first polymer material (30) and the second material (40), and wherein the extrusion axis is parallel to the movement of the multilayered extrudate; depositing a multitude of layers of the multilayered extrudate in a preset pattern on a platform (2); and fusing the multitude of layers to form the three dimensional object. An article of manufacture comprising: a three dimensional object is also disclosed.
