ADOPTED_FROM:EN ISO 17296-4:2016 ISO 17296-4:2014 covers the principal considerations which apply to data exchange for additive manufacturing. It specifies terms and definitions which enable information to be exchanged describing geometries or parts such that they can be additively manufactured. The data exchange method outlines file type, data enclosed formatting of such data and what this can be used for. ISO 17296-4:2014 enables a suitable format for data exchange to be specified, describes the existing developments for additive manufacturing of 3D geometries, outlines existing file formats used as part of the existing developments, and enables understanding of necessary features for data exchange for adopters of the International Standard. ISO 17296-4:2014 is aimed at users and producers of additive manufacturing processes and associated software systems. It applies wherever additive processes are used, and to the following fields in particular: production of additive manufacturing systems and equipment including software; software engineers involved in CAD/CAE systems; reverse engineering systems developers; test bodies wishing to compare requested and actual geometries.
