UL, a leading global safety science company, has announced that Lockheed Martin is the first organization to be certified to UL 3400, a set of safety guidelines that address the various hazards associated with additive manufacturing facilities. The certification was issued to Lockheed Martin’s Additive Design and Manufacturing Center in Sunnyvale, Calif. where the company focuses on technology that supports its military, commercial and civil space portfolio.
Additive manufacturing has experienced substantial growth in recent years, particularly with metals and alloys that can be 3D printed from powder. This growth is accompanied with new safety risks specific to the material, equipment and overall operation of the facility. UL published UL 3400, Outline of Investigation for Additive Manufacturing Facility Safety Management.
UL 3400 takes into consideration the three layers of safety: material, equipment and the facility as a whole. The guideline references applicable standards from the Occupational Safety and Health Administration, the National Fire Protection Association, UL and ASTM International among others. The guideline covers the potential hazards and risk mitigation measures required for the safe functioning of the facility.
