UKAEA Deploys Advanced 3D Printing for Fusion Components

The United Kingdom Atomic Energy Authority (UKAEA) has announced the commissioning of two advanced additive manufacturing (3D printing) machines at its Central Support Facility to produce specialized components for future fusion power plants.

• Two complementary 3D printing technologies have been deployed: an electron beam powder bed fusion machine (eMELT by Freemelt) for tungsten components and a selective laser manufacturing machine (SLM280 by Nikon SLM Solutions) for complex geometries and material combinations.
• These machines aim to produce plasma-facing components capable of withstanding extreme fusion conditions, reduce reliance on traditional welding, and demonstrate scalable production methods essential for commercial fusion energy development.
