Demonstration of a sustainable circular-by-design manufacturing system based on additive manufacturing

AI-Powered Circular Manufacturing with Additive Technologies

DIAMETER is a Horizon Europe project pioneering the transition to a more sustainable, digital manufacturing industry. By combining hybrid additive manufacturing (AM) with advanced AI-driven decision tools, DIAMETER empowers industries to implement circular-by-design production models that reduce waste, cut emissions, and increase efficiency.

Meet DIAMETER at Formnext 2026

DIAMETER will exhibit at Formnext 2026 in Frankfurt, 17–20 November, Hall 11.0, Stand C77. Visit us to see the project’s industrial pilot cases, learn about the DIAgonal platform in development and explore DIAdemia, the project’s e-learning platform.

Transforming Metal Manufacturing for Industry 4.0

DIAMETER delivers a robust circular manufacturing framework that enables companies to:

  • Reduce carbon emissions by up to 30% through sustainable design optimization
  • Shorten production cycles by 20% using hybrid manufacturing and smart planning
  • Integrate reuse, repair, remanufacturing, and recycling strategies across product lifecycles
  • Comply with European Green Deal and EU Digital Product Passport (DPP) initiatives

At the heart of the project is a powerful AI-powered sustainability algorithm that calculates both environmental and economic impacts across manufacturing processes—enabling informed, realtime decisions that align with circular economy goals.

Digital Platforms Driving Sustainable Innovation

DIAgonal: Decision Support for Smart Manufacturing

The DIAgonal platform helps manufacturers embed circularity into design and production,featuring:

  • Design for Environment Tool – Optimize designs for recyclability, reusability, and energy efficiency
  • Process Planning Tool – Select ideal hybrid workflows and generate optimized toolpaths
  • Circular Sustainability Evaluation Tool – Recommend end-of-life strategies (reuse, remanufacture, recycle) based on real data

DIAdemia: Upskilling the Workforce for the Circular Economy

DIAdemia is our e-learning platform built on open-source ILIAS technology. It delivers:

  • In-depth training on sustainable manufacturing and circular principles
  • Hands-on modules covering AM technologies and digital process optimization
  • Certification paths for engineers, technicians, and sustainability professionals

Real-World Impact: A Greener, Smarter Industry

Through a network of four industrial pilots, DIAMETER is validating its technologies in real settings, with measurable outcomes:

✅ 30% fewer carbon emissions thanks to eco-design and reduced material waste
✅ 20% faster production with hybrid process optimization
✅ Full DPP compatibility, ensuring product traceability and regulatory alignment
✅ 50+ professionals trained, supporting a skilled, sustainability-ready workforce

An International Alliance Driving European Innovation

DIAMETER unites 17 partners from Europe, Turkey and Australia. The consortium includes top
