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.

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
