Additive manufacturing (structural and non-structural)

Modern Methods of Construction, Introducing the MMC definition framework, published by Ministry of Housing, Communities & Local Government (MHCLG) in 2019 defines 7 categories for MMC:

• Category 1 – Pre-manufacturing (3D primary structural systems).
• Category 2 – Pre-manufacturing (2D primary structural systems).
• Category 3 – Pre-manufacturing components (non-systemised primary structure).
• Category 4 – Additive manufacturing (structural and non-structural)
• Category 5 – Pre-manufacturing (non structural assemblies and sub-assemblies).
• Category 6 – Traditional building product led site labour reduction / productivity improvements.
• Category 7 – Site process led site labour reduction / productivity / assurance improvements.

Category 4 – Additive manufacturing (structural and non-structural) is defined as:

‘The remote, site based or final workface based printing of parts of buildings through various materials based on digital design and manufacturing techniques.’
