  • Publication number: 20190193336
    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.
