Abstract: A method is described in which a 3MF (3D Manufacturing Format) file is adapted for use with a three-dimensional (3D) printing system. The 3MF file includes at least one 3D model having polygonal slices. The method comprises parsing the 3MF file, generating an intermediate file for the 3D model included in the 3MF file, and performing a polygon cleanup for the polygonal slices of the 3D model of the intermediate file. The polygon cleanup is performed using an implementation of a polygon clipping algorithm. Further, the method comprises generating a resulting file for the intermediate file comprising the polygonal slices for which the polygon cleanup has been performed.

Abstract: A controller for an additive manufacturing system comprises a processor to: receive data associated with a 3D printing job to generate at least one 3D object using one or more materials; determine, based on the received data, at least one operational parameter to be used by the additive manufacturing system in completing the 3D printing job; calculate, based on the received data, a value of at least one geometric parameter associated with the 3D printing job; and for at least one of the one or more materials, determine, based on the determined at least one operational parameter and the calculated value of the at least one geometric parameter, an amount of the at least one material to be used by the additive manufacturing system to complete the 3D printing job.

Abstract: A method is described in which a 3D printing file is processed, the 3D printing file having a header and including a plurality of compressed files. The method comprises reading a content of the header of the 3D printing file, identifying, based on the header content, a relation file among the plurality of compressed files, identifying, based on the relation file, a main 3D model file among the plurality of compressed files. Further the method comprises creating, by uncompressing the main 3D model file, a data stream, and analyzing, with a parser, the data stream, thereby directly processing the main 3D model file when being uncompressed.
