Systems and methods for printing a 3D object on a three-dimensional (3D) printer are described. The methods semi-automatically or automatically delineate an item in an image, receive a 3D model of the item, matches said item to said 3D model, and send the matched 3D model to a 3D printer.

A method for 3D printing of an object that is larger than the printing area of a 3D printer and a device using the method. The 3D printing method includes receiving 3D mesh data of the object, determining whether the 3D mesh data is included in the printing area of the 3D printer, generating partitioned mesh objects by partitioning the 3D mesh data if the 3D mesh data is not included in the printing area of the 3D printer, forming a connector for connecting the partitioned mesh objects, arranging the partitioned mesh Objects in the printing area, and printing the arranged partitioned mesh objects in 3D.

Embodiments describe constructing game-related objects through additive manufacturing systems. At least one construction configuration for building a game-related object is advanced at least partly due to at least one game task result being attained by a user and/or due to when an object is constructed and/or arranged to be built. Several embodiments demonstrate select game task results leading to determined construction configurations instead of alternative construction configurations, causing, for instance, a differing design, complexity, function, and/or number of constructed object portions. Game task results in certain embodiments lead to multiple distinct portions of one or more objects being constructed concurrently and/or successively, at one or more locations. Selected methods and systems disclose objects constructed as awards, puzzles, other assembly challenges, educational challenges, wagering elements, electronic game elements, in multiple inseparable portions, and/or for other entertainment purposes.
