Abstract
The apparatus () includes a housing (), a chamber () disposed in the housing, at least two light emitting diodes (LEDs) () disposed within the housing (), and a user interface () disposed on an exterior () of the housing. The chamber () is adaptable to each of an open, closed, and hermetically sealed configuration. The chamber () includes a material transparent to actinic radiation and light from the LEDs () enters the chamber from more than one direction. The user interface () includes a display () and program switches () configured to adjust at least three operational parameters of the apparatus. The apparatus () further includes a vacuum pump () operatively coupled to the chamber (). The system includes the apparatus () and an article (). An article includes layers of at least one photopolymerized crosslinked composition and a low extractable component content. A method of post-curing an article includes obtaining an article (), placing the article in an apparatus (), inputting a post-cure program or accessing a saved post-cure program through the user interface (), and running the post-cure program. The post-cure program includes light intensity provided by a light source () and length of time of light provided by the light source (), plus a delay time between initiation of light provided by the light source () and initiation of vacuum pulled by the vacuum pump () and/or a delay time between initiation of vacuum pulled on an interior of the chamber () by the vacuum pump () and initiation of light provided by the light source ().
