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 modular light for removably attaching to a bio-printer robot end effector, where the light includes: an annular modular light ring housing with an annular opening for receiving the end effector of the bioprinting robot; the housing substantially surrounding a dispensing tip of the end effector; a power supply interface to receive electrical power from the end effector; a plurality of LEDs positioned annularly around the end effector within the annular modular light ring housing, where the plurality of LEDs are spaced in at least two annular rows, where each of the at least two annular rows are at a unique elevational position within the annular modular light ring housing with respect to a light output plane of the annular modular light ring housing; the LEDs are in electrical communication with the power supply interface; and a controller communicatively coupled with the LEDs and the power supply interface.

A method of manufacturing golf balls having a core and a cover of at least one layer encasing the core includes the steps of producing a core by molding and vulcanizing a rubber composition containing (A) a base rubber, (B) an α,β-unsaturated carboxylic acid and/or a metal salt thereof, and (C) an organic peroxide; and heat-treating the core for 1 to 24 hours at between 175 and 300° C. Golf balls which undergo little energy loss and have a high initial velocity can be obtained by this method.
