Processing of 3D printing files

A 3D printer system, comprising:

• a processor;
• wherein the processor is to process a 3D printing file having a header and including a plurality of compressed files, processing comprises to:
• read the content of the header of the 3D printing file;
• identify, based on the header content, a relation file among the plurality of compressed files that points to a main 3D model file representing a plurality of objects to be created via a 3D manufacturing process;
• identify, based on the relation file, the main 3D model file among the plurality of compressed files;
• create, by uncompressing the main 3D model file, a data stream;
• and
• analyze, with a parser, the data stream, thereby directly processing the main 3D model file when being uncompressed.

A non-transitory computer readable medium for storing a program causing a computer processor to perform a method for processing a 3D printing file, the 3D printing file having a header and including a plurality of compressed files, the non-transitory computer readable medium comprising:

• instructions to read the content of the header of the 3D printing file;
• instructions to identify, based on the header content, a relation file among the plurality of compressed files that points to a main 3D model file representing a plurality of objects to be created via a 3D manufacturing process;
• instructions to identify, based on the relation file, the main 3D model file among the plurality of compressed files;
• instructions to create, by uncompressing the main 3D model file, a data stream;
• and instructions for a parser to analyze the data stream, thereby directly processing the main 3D model file when being uncompressed.
