28、methods Part 4: Overview of data processingDIN EN ISO 17296-3:2016-12 EN ISO 17296-3:2016 (E) 4 IntroductionAdditive manufacturing is a process of joining bulk raw materials to make parts from 3D model data, usually layer upon layer, as opposed to subtractive manufacturing and formative methodologie

29、s. It is an inherent part of the parts development or production process. It is used to manufacture prototypes and production parts.This part of ISO 17296 aims to offer recommendations and advice to machine manufacturers, feedstock suppliers, machine users, part providers, and customers, to improve

30、communication between these stakeholders concerning test methods.This International Standard has been developed within a set of consistent documents from terminology to test methods and data exchange.The manufacturing of parts by additive manufacturing processes is subject to numerous variables. The

31、 processes described in ISO 17296-2 can be used to manufacture parts that meet technological requirements only if these factors are controlled, optimized and, if necessary, customized for each order. When assessing parts quality, comparison with the specific requirements is one of the most important

32、 aspects.Additive manufacturing processes require the selective application of thermo-physical and/or chemical mechanisms to generate the part. Thus it is possible to produce parts with different characteristics, depending on the method used and the process parameters. However, complete testing of a

33、ll parts characteristics is neither cost-effective nor technologically feasible. Therefore, when formulating parts specifications, the nature and scope of testing is an important issue.DIN EN ISO 17296-3:2016-12 EN ISO 17296-3:2016 (E)5 1 ScopeThis part of ISO 17296 covers the principal requirements

34、 applied to testing of parts manufactured by additive manufacturing processes.This part of ISO 17296 specifies main quality characteristics of parts, specifies appropriate test procedures, and recommends the scope and content of test and supply agreements.This part of ISO 17296 is aimed at machine m

40、orresponding test methods4.1 GeneralEach development and fabrication phase of a part has a specific purpose. The performance criteria determine the type of part and the choice of additive manufacturing process. This part of ISO 17296 develops the following main quality characteristics: feedstock: bu

41、lk raw material requirements: powder particle size, morphology, surface and distribution, density (tap and apparent), flowability/pourability, ash content, and carbon content; parts: surface requirements: appearance, surface texture, and colour; geometric requirements: size, length and angle dimensi

42、ons, dimensional tolerances, and geometrical tolerancing (deviations in shape and position); mechanical requirements: hardness, tensile strength, impact strength, compressive strength, flexural strength, fatigue strength, creep, ageing, frictional coefficient, shear resistance, and crack extension;
