The International Association of Classification Societies (IACS) has published a new recommendation, Rec.186, that meets the need for a standardized approach to integrating additive manufacturing (AM), commonly referred to as 3D printing, into marine and offshore applications.
The maritime industry continues to embrace developments in manufacturing technologies to enhance efficiency and sustainability in shipbuilding and offshore operations. Additive Manufacturing (AM) has emerged as an alternative to traditional manufacturing processes by fusing materials to produce objects from a digital 3D model into a series of 2D cross sections for layer-by-layer physical prints, ultimately producing a 3D object.
Unlike conventional methods such as casting, forging, and welding, AM offers greater design freedom, reduced material waste, and the potential for on-demand production. Its flexibility allows for localized production and customization, providing tailored solutions for specialized marine and offshore applications.
‘Rec. 186: Additively Manufactured Metallic Parts for Marine and Offshore Applications’ establishes a framework for the qualification, approval, and certification of additively manufactured metallic parts. This recommendation provides detailed guidance for key aspects of the AM process, including part design, feedstock selection, AM processes, post-processing, and inspection/testing.
By incorporating recognized international standards such as ISO/ASTM 52900 and AWS D20.1, it aligns AM technology with
