Additive Manufacturing

Frequently Asked Questions

Equipment/Software

DIN 35224: 2016
Welding for aerospace applications. Acceptance inspection of powder bed based laser beam welding machines for additive manufacturing

 

BS ISO/ASTM 52915: 2016
Standard specification for additive manufacturing file format (AMF). Version 1.2

Identical to ISO/ASTM 52915

A framework for an interchange format to meet the current and future needs of additive manufacturing technology is specified. Up to now STL file format has been the industry standard for transferring data between design programs and additive manufacturing equipment and its functionality is limited. The additive manufacturing file (AMF) can be prepared, displayed, and transmitted on paper or electronically, provided the information required by this specification is included. When prepared in a structured electronic format, strict adherence to an extensible markup language (XML)schema is required to support standards-compliant interoperability. A W3C XML schema is detailed and Annex A1 contains an implementation guide for such representation.

The principal requirements applied to testing of parts manufactured by additive manufacturing processes are described. The main quality characteristics of parts and appropriate test procedures are specified, and recommendations given for the scope and content of test and supply agreements. The standard is aimed at machine manufacturers, feedstock suppliers, machine users, part providers, and customers to facilitate the communication on main quality characteristics, and applies wherever additive manufacturing processes are used
