Bundesnetzwerk 3R is a German network focused on advancing the principles of Replace, Reduce and Refine in research involving animals. It connects institutions and experts working on 3R methods across Germany and provides information about research, funding and developments in alternative approaches. The network’s website features news, interviews, project profiles and practical guidance, alongside explanations of regulatory issues and knowledge transfer.

Its coverage includes organoids, 3D tissue models, chip technologies, bioprinting and other New Approach Methods, as well as research into animal welfare and improved experimental practices. Visitors can explore a map of 3R research locations, add their institution, and, as registered members with a profile, access a protected area containing further information about experts. The site also lists relevant courses, seminars and other events.

By bringing together research updates, resources and community information, Bundesnetzwerk 3R helps make work in 3R methods visible and supports exchange among researchers and organisations in Germany
