A method for preparing an additive manufacturing program includes a loading step, a dividing step, an overhang calculating step, a subdividing step, a maintaining step, and an outputting step. In the loading step, a three-dimensional model is loaded. In the dividing step, the three-dimensional model is divided into divided layers. In the overhang calculating step, an overhang angle or overhang length of the divided layer is calculated. In the subdividing step, at least a part of the divided layer including an overhang portion is subdivided into two or more in a lamination direction. In the maintaining step, neither subdivision of the divided layer nor addition of a support structure supporting the divided layer is performed. The subdividing step and the maintaining step are selectively performed based on the overhang angle or overhang length. In the outputting step, an additive manufacturing program defining a command pertaining to additive manufacturing is output.

Object model data is obtained, representing one or more objects to be generated by an additive manufacturing system. An object model is generated, representing an arrangement of the one or more objects within a build volume, by determining a solution to a packing optimization function. A layer of the object model is analysed to determine a parameter representing the complexity of the layer, and if the determined parameter exceeds a given threshold, the process is repeated by generating a revised object model representing a different arrangement of the one or more objects within the build volume.
