Digial Factory for Dual-Use Purposes

Büttner Kft. has established a cutting-edge dual-use digital manufacturing facility that integrates advanced 3D metal printing technologies to serve both military and civilian markets. At the heart of this initiative is the DED-WL (Directed Energy Deposition - Wire Laser) process, employing the Meltio M450 system and Engine Robot Integration to achieve highly flexible, rapid, and cost-efficient production using exotic metal alloys and complex part geometries.

Key technological innovations produced by this digital factory include:

• 3D Printed Fragmentation Grenade Casings: These next-generation munitions are optimized for use in grenade launchers and FPV drones. They are protected by utility model rights and have successfully passed 250-bar pressure tests, with a current Technology Readiness Level (TRL) of 6.

• Additively Manufactured Suppressors: Featuring a patented adaptive flowthrough system, these suppressors are suitable for automatic fire and are designed for easy maintenance and servicing.

• CVD-Coated Weapon Barrels: Developed to replace conventional hard chrome plating and nitriding, this technology offers superior performance and durability with reduced costs.

The project is further strengthened through strategic collaboration with the 3D Printing and Visualization Centre of the University of Pécs, a key research partner providing scientific expertise, material development support, and technological validation. This academic-industrial partnership enhances innovation and supports continuous improvement in additive manufacturing processes.

The dual-use nature of the factory enables flexible transition between defense and civilian production, from prototype to small-series manufacturing, contributing to Hungary’s national defense ecosystem while promoting export-ready innovations. It also aligns with Industry 4.0 principles and supports sustainable manufacturing practices.

Together, Büttner Kft. and the University of Pécs are positioning Hungary at the forefront of metal additive manufacturing on a European and global scale.
