It's entirely possible! Two 2009 films nominated made extensive use of 3D printing in their productions: Avatar, nominated for Best Picture of the Year among others, and Coraline, nominated for Best Animated Feature Film.
James Cameron, the man behind Avatar used 3D printing to produce figurines with which lighting tests were performed for "every shot in the movie". The figurines were produced by Legacy Effects.
LAIKA productions created thousands of objects used for extensive stop-motion animation in the movie Coraline. One of the fascinating outcomes was a system to create different facial expressions: 208,000 were possible.
Both projects made use of Objet 3D printers.
Good luck to both films in tonight's show.
