Certification mark for Industrial AM production site

Certification mark for industrial am production site

 

Scope:

The certification mark applies to the 3D printing service expertise of industrial additive manufacturing (AM) centres.

Basis of certification:

The certification mark is awarded within the framework of voluntary testing and certification. ‘Additive Manufacturer’ indicates a production site operating AM machines and offering parts produced by 3D printing, with a focus on premium customer-service quality and part quality as well as health and safety considerations. The quality criteria are defined in the DIN SPEC 17071 standard and are independently audited by TÜV SÜD experts.

The test procedure developed by TÜV SÜD is based on numerous standards such as:

AM – cross-technology

  • DIN SPEC 17071 (draft) (Guidelines for quality-assured processes at additive manufacturing centres)
  • ISO/ASTM 52901 (Requirements for purchased AM parts)
  • ISO 17296-3 (Main characteristics and corresponding test)
  • ISO/ASTM 52900 & ISO/ASTM 52921 (Terminology for additive manufacturing)
  • ISO/ASTM 52910 (Guidelines for additive manufacturing design)
  • ASTM F2971 (Reporting Data for Test Specimens) 

AM – technology-specific

  • DIN 35224 (Acceptance inspection of PBF machines)
  • DIN 35225 (Qualification testing of operators for PBF machines)
  • DIN 65123 (Inspection of metallic components)
  • DIN 65124 (Technical Specifications for metallic materials with PBF)
  • VDI 3405 Blatt 1 (Laser sintering of polymer parts – Quality control)
  • VDI 3405 Blatt 2 (Laser beam melting of metallic parts)
  • VDI 3405 Blatt 3 (Design rules for part production using laser sintering and laser beam melting)
  • ASTM F3091/F3091M (Standard Specification for PBF of Plastic Materials)
  • ASTM F3122 (Evaluating Mechanical Properties of Metal Materials)

Excerpts from general standards

  • EN ISO 9001 (clause 8 “Operation” and clause 9 “Performance evaluation”)
  • ISO 27001 (clause 4 “Context of the Organization” and clause 5 “Leadership”)

Dimensional accuracy

  • ISO 286-1 (Basis of tolerances, deviations and fits)
  • ISO 1101 (Tolerances of form, orientation, location and run-out)
  • DIN EN ISO 1302 (Indication of surface texture in technical product documentation)

Test methods

  • EN ISO 60 & 61 (Plastics – Determination of apparent density)
  • ISO 3369 (Impermeable metals – Determination of density)
  • ISO 3923-2 (Metallic powders – Determination of apparent density)

KeyWORDS of the certification mark:

  • QM for AM processes

    The test specification ensures that an advanced QM system is installed along the value chain at the AM production site. This includes the following topics: corporate management, customer management, order management, production management, 3D printing and post-processing.

    Aspects addressed include the expertise of the specialist staff, the organisation of the production site and the customer contact and service quality.

  • Quality assurance for industrial applications

    Audited companies should show demonstrable commitment to QA, so that quality assurance measures are addressed along the entire value chain. Run charts, process descriptions, work instructions and checklists for documentation are components of the measures and are checked for meaningfulness and completeness by our technical experts.

     

  • Reproducible and traceable processes

    Representative orders are used as a basis to verify along the entire value chain whether they are processed reproducibly and transparently. This includes control of the necessary documentation as well as its systematic filing and case-related implementation of test specimens.

  • Controlled material handling

    Essential aspects of material handling within the material cycle are consistently monitored. These support quality monitoring and include material qualification, incoming inspection, storage, reuse and quality-conscious handling of the material in the production steps - irrespective of whether in the AM system or other peripheral equipment.
