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.

A system for manufacturing a three-dimensional article includes a controller configured to: receive an input file defining a geometry of the three-dimensional article; receive information specifying an interface surface of the article over which the article will fit against a three-dimensional body; slice the geometry; identify intersecting slices that intersect the interface surface; and for the intersecting slices, alter a halftone range along the interface surface. Along the interface surface, the article slidingly engages the three-dimensional body. The sliding engagement can be sufficient to provide a fluid seal along the interface surface.
