Guidance Notes for Additive Manufacturing

A path to certification for additive manufacturing.

Our Guidance document helps manufacturers prove the safety of AM parts.

Additive manufacturing (AM) techniques have significant barriers to overcome in delivering a manufacturing process that produces consistent quality and safety.

Lloyd's Register and TWI have produced "Guidance Notes for the Certification of Metallic Parts made by Additive Manufacturing" to help manufacturers forge a path to certified AM parts.

The Guidance Notes provide a goal-based framework that manufacturers can follow to achieve certification with LR, and subsequently provide confidence to end users that a specific part manufactured using AM meets the required codes, standards, controls and best practises.

Key topics addressed in the Guidance Notes, and where LR can support your organisation further, include:

  • Suitability for additive manufacturing
  • Certification approach and activities
  • Design
  • Materials
  • Manufacturing
  • Post-processing
  • Inspection and testing
  • Organisational requirements


Fill out the form below and the document will be emailed to the address you provide.
