Manufacturing adoption of metal additive manufacturing (AM) is increasingly being linked to the development of closed-loop material supply chains, as manufacturers seek greater access to critical metals and resilience against supply disruptions, according to a white paper from Additive Manufacturing Research (AM Research) and Continuum Powders.
The white paper, Metal AM at Scale: The Closed-Loop Materials Era, reports that the value of metal 3D-printed parts grew from just under US$3 billion in 2016 to more than US$8 billion in 2025.
It noted the continued expansion of metal AM is increasing the need for resilient supply chains capable of supporting production at scale.
According to the report, recycling is becoming more relevant as powder-based metal AM moves beyond prototyping and into higher-volume production. Technologies including powder bed fusion, directed energy deposition and metal binder jetting are being used alongside recycling-enabled material ecosystems, allowing manufacturers to recover and reuse metal feedstock.
AM Research forecasts that the value of parts produced using powder bed fusion will increase from about US$6 billion in 2025 to around US$30 billion by 2034.
The report also identifies aerospace and defence as a leading market by parts value over the period, while highlighting growing applications across infrastructure and other strategic sectors.
The white paper argues that as demand grows for materials such as nickel, titanium, copper and specialty alloys, manufacturers will need strategies that improve feedstock availability, reduce exposure to supply disruptions and support the reuse of valuable metals.
It describes closed-loop material systems as an increasingly important manufacturing capability rather than solely a sustainability initiative.
The report also points to examples involving data centre infrastructure and aerospace, energy and defence applications, where demand for specialised materials is increasing.
It noted the next phase of metal AM growth will depend increasingly on scaling production and establishing reliable sources of specialised powders.
The white paper concludes that manufacturers may face changing production and supply-chain requirements, making access to circular metal supply chains an important consideration as additive manufacturing scales.
