In batch additive manufacturing processes such as MJF and MetalJet, parts are produced in batches as opposed to printed individually. A pre-requisite is that parts are grouped and oriented into what is called a build. This process is sometimes called ‘nesting’ or ‘packing’ and is performed by professionals sometimes referred to as DFM Engineer or simply DFM (Design for Manufacturing). As a costly process, solutions have been developed to automate it. Specific build preparation guidelines are developed to specify things like minimal distance between parts, between part and the walls of the build volume, part orientation (flat vs tilted) and placement or not of control parts. While some automatic nesting solutions are provided as part of an attended workflow, in scenarios where automatic nesting should be done completely unattended, a filtering step is needed to prevent non-complying parts to be placed in a build.
