Fronius Launches an Automated Metal 3D Printing Cell Built for Production

Austrian welding specialist Fronius has launched the Fronius Additive Cell, a turnkey Wire Arc Additive Manufacturing (WAAM) system designed to produce metal parts in an automated, production-ready setup. The system combines Fronius CMT welding hardware, robotic automation, and the company's own Vectris software platform into a single package aimed at aerospace, automotive, pressure vessel, and oil and gas customers.

How WAAM Fits Into Production

Wire arc additive manufacturing builds metal parts by depositing molten metal wire layer by layer, similar to how an FDM printer extrudes plastic, but at temperatures and deposition rates suited for structural metals. WAAM is gaining traction for producing spare parts, complex one-off components, and low-volume production runs where conventional manufacturing would be slow or expensive.

The Fronius Additive Cell is engineered around the company's CMT Additive Pro process, based on the Cold Metal Transfer technique. CMT operates as a relatively cool dip transfer arc process, delivering a higher deposition rate than other arc welding methods while keeping heat input low. Lower heat input means less distortion and better mechanical properties in the finished part, which matters for applications where dimensional accuracy is critical.

Software That Handles the Complexity

The system runs on Vectris, Fronius's integrated software platform. Vectris combines the machine tool service kit and post-processor into one interface, with an integrated kinematic model and validated welding operations specifically for additive processes. It can detect different component regions automatically and adjust parameters for walls, infill, panels, or joints.

Behind that, FroArc translates the build styles into code for the welding robot, switching parameters at the right location without pausing the process. That kind of automated parameter switching is what separates a working production cell from a setup that requires constant operator attention.

Anna Dieplinger, Key Product Manager for additive manufacturing at Fronius, described the Additive Cell as a system where every component was designed to work with the others, resulting in a stable manufacturing process. The company is offering consultation, feasibility studies, and process development services alongside the hardware, and plans to license pre-validated welding parameter 'recipes' for specific materials and applications.

Practical Use Cases

Fronius says the Additive Cell is suited for reverse engineering existing parts, optimizing legacy designs, and building entirely new geometries. The company's prototyping and manufacturing centre can assist customers through the full development cycle, from concept to qualified production.

Manuel Stinglmayr, Business Development at Fronius, noted that WAAM enables decentralized, location-independent manufacturing without complex production lines. Irregular geometries can be built to high quality standards without wasting material, making the process attractive for industries that have historically struggled with long lead times for custom metal parts.

The Fronius Additive Cell is scheduled for a full introduction at Formnext 2026. For companies that have been testing WAAM on generic welding setups, a purpose-built, software-integrated cell from one of the welding industry's established names could be a significant step toward wider industrial adoption.
