Support Action for Standardisation in Additive Manufactruring

Final Report Summary - SASAM (Support Action for Standardisation in Additive Manufactruring)

Executive Summary:
SASAM's mission is to drive the growth of AM to efficient and sustainable industrial processes by integrating and coordinating Standardisation activities for Europe by creating and supporting standardisation in the field of AM.
Even if the mechanical and materials properties of todays AM products are on an adequate level for commercial use, the lack of availability of an International and European Standard is hampering real industrial implementation of AM technology. The development of corresponding Standards is an important step to improve the current situation, and make the benefits of additive manufacturing accessible and useful for manufacturing purposes to numerous sectors of industry.

Specific objectives of SASAM include the following:
- Setting up a European wide structure with national nodes of AM experts (Industry and RTDs) together with National Standard Bodies.
- Provide an updated/aggregated roadmap for AM scoping/including the challenges for Standardisation.
- Identification of and preparation of Working Groups / Work items in the areas of relevant AM standardisation items which apply to the design, fabrication and assessment of parts produced by additive fabrication
- preparation of a first draft guideline / framework of a normative document on the above work items
- Organise Industrial information days on AM Standardisation – Dissemination

Project Context and Objectives:
SASAM started by identifying the stakeholders and key players in the area of standardisation of Additive Manufacturing to learn and understand their view of the AM market as well as the needs for and the probable effects of standardisation. This info was combined with information from existing roadmaps and vision statements for sectors that have a strong link to Additive Manufacturing (such as the Strategic Research Agenda from the AM-Platform). In the WP2 the real Roadmap for AM standardisation was developed which clearly shows the vision and priorities of the industry and the steps required to transform the vision of a standardization that foster innovation and development of AM into reality. The Additive Manufacturing Standardisation Roadmap (a SASAM only as well as a public document was draft) is a proactive document, which describes a vision for the Additive Manufacturing industry. The Roadmap lists the key elements that need to be put in place to ensure that the industry can reach full implementation of standards in AM, to transform it into a controlled and accepted technology for industrial manufacturing alongside the already established conventional technologies.
Four focus areas were identified, each of them populated by individual Working Groups. They comprise: Terminology, Methods – Processes – Materials, Test methods and Data processing
The dissemination work package created and extended awareness of and an interest for Standardisation for Additive Manufacturing as well as brought partners from the whole value chain together in order to initiate and establish appropriate and necessary contacts for further interaction. Therefore, a platform to raise interest in an industrial standard for Additive Manufacturing outside the already established community was created by setting up a website www.SASAM.eu and several workshops + Conferences in combination with CEN (STAIR-AM initiative) were held.

Project Results:
One of the key final results is a Standardisation roadmap, based on input from 102 relevant stakeholders, which can be used as a background structure for a European Standard, a Technical Specification or a Technical report. The roadmap comprises context and background of AM, an explanation on how can standards support industrial implementation of AM, an overview of relevant existing AM standards and which existing relevant standards from other sectors do fit and which gaps exist. Also a description of and priority list of which standards are (to be developed) to help/assist industry to be more compliant is provided. Input from stakeholders is presented in terms of requirements, wishes, priorities and a roadmap is given.
A background structure for a European Standard, a Technical Specification or a Technical report was drafted which can be used for norming institutes to actually write the standards.
The other main impact is that a liaison of SASAM activities with the norming institutes is established: national as well as CEN and ASTM involvement is included to secure linking with EU standardisation policies. From now on, Standardisation will be a standard element of the AM-Platform meetings agenda to keep close track with the AM stakeholders needs and requirements

Potential Impact:
In the past, development, modification and industrial use of AM production processes have been quite dispersed, uncoordinated and to a large extent aimed towards prototyping purposes. Even if the mechanical and material properties of today’s AM products are on an adequate level for commercial use, the lack of availability of an International and European Standard is hampering real industrial implementation of AM technology.
Due to the nature of AM, where the basic principle to build products is by successive addition of material, products produced by AM-technologies will show different values of the material properties depending on the parameter set-up used during manufacturing. This makes the evaluation and quality management of the products complicated and maybe even unpredictable, which is unacceptable for, for example the aeronautical and medical industries.
The development of corresponding standards is an important step to improve the current situation and makes the benefits of additive manufacturing accessible and useful for manufacturing purposes to numerous sectors of industry.

In order to have an idea of the scope of the industry, one should be aware that there are already about 30 laser sintered components produced with AM-processes installed in the Boeing 787 (Ref Scott Martin, Boeing, IAG member) and the numbers are likely to raise dramatically in the future. According to estimations from Airbus Industries, an aircraft produced entirely by additive manufacturing would be 30 % lighter and 60 % more cost effective than by current machines. Resources and energy efficiency combined with economical production are the central challenges for commercial aircraft construction in the future. Additive Manufacturing is one of the key technologies to address these challenges. Additive Manufacturing technologies support and enable
· Advanced European industrial production on a cost- and resource-efficient (sustainable) footprint.
· The exploitation of AM technology as another manufacturing tool will encourage innovation and enhance the competitiveness of labour in Europe.
· A globalised economy.
· The production of personalised goods and services.
· The development and implementation of Advanced, ICT-Enabled Manufacturing Systems.
The Strategic Research Agenda SRA 2013, drafted by the AM-Platform (the European Platform for AM) refers to standardisation as an important tool to facilitate innovation and bring new products to the market.
