Abstract: Methods of producing an additive manufactured part with a smooth surface finish and customized properties include creating a compensated design that serves as a print recipe for an additive manufacturing process for a part, where the creating comprises modifying a desired design with a geometric offset correction to compensate for a first portion of an uncured surface finish material to be retained on the part. A spinning device is provided that has a platform. The part is formed with the additive manufacturing process and secured to the platform, where the part is at least partially wetted with the uncured surface finish material. The platform is rotated, where a second portion of the uncured surface finish material is removed due to forces imparted by the rotating. The uncured surface finish material is chosen to customize a property of the part.

Abstract: Methods of creating additive manufactured parts from expanding foam material include printing a part made of an expandable foam, using an additive manufacturing system. The foam is printed in an unexpanded state and has a closed layer at an external surface of the part. Expansion of the part is controlled, using the additive manufacturing system, wherein the expansion is performed after the printing. Methods also include modeling an expansion of a part made of an expandable foam, and printing the part made of the expandable foam, using an automated additive manufacturing system and according to the modeling. The foam is printed in an unexpanded state and has a closed layer at an external surface of the part.
