Metal 3D printing with Fronius Additive and CMT Additive Pro

Wire arc additive manufacturing
The additive manufacturing process for metal 3D printing, also known as wire arc additive manufacturing (WAAM), enables quick, cost effective, and precise component production. Based on this approach, Fronius Additive is revolutionizing the manufacturing industry.
The wire-based, arc-driven CMT process offers huge design flexibility and the ability to produce complex component geometries, while still delivering high deposition rates. All these benefits make Fronius Additive the ideal choice for prototyping and small batches.

CMT—a stable arc with no exceptions
The synergy between stability and flexibility is essential to producing components in additive manufacturing. A reliable welding process and efficient heat management play a critical role.
Thanks to its revolutionary reversing wire movement, the CMT process is extremely stable, making it perfect for additive manufacturing. Layers are built up consistently, evenly, and virtually spatter-free,
ensuring that the welded layers and components produced meet the highest quality standards.

CMT Additive Pro—additive features packed into one characteristic
Exclusive features for maximum control in additive manufacturing
We developed the CMT Additive Pro welding characteristics specifically for additive manufacturing. They make it easy to achieve a reproducible uniform layer structure, as well as deal with other challenges.
More constant deposition rate
Thanks to the deposition rate stabilizer, the wire speed remains almost constant throughout the process, allowing you to achieve the desired deposition rate despite varying external influences.
- Simplified welding path planning
- Optimized transmission of welding parameters
- Increased reproducibility
Adjustable heat input
The power correction feature enables heat input at a steady wire speed to be precisely regulated, so you can keep the seam geometry virtually constant, even at higher temperatures.
- Less overfill due to improved layer height consistency at connecting points
- Improved control of the weld seam flow at the same deposition rate
- Energy input can be reduced at higher interpass temperatures
Additional signal for manipulator control and position correction
Initial detection of the CTWD during setup expands the spectrum of available signals. This makes it easier to compare the manipulator position and deposited structure without external sensors.
Welding start in pulsed arc
It’s simple to start welding in pulsed arc, so you can achieve sufficient penetration and adhesion without adjusting the operating point.
- Sufficient penetration and adhesion without adjusting the operating point
- Layer height is almost constant in the welding start area
- Fewer fusion defects
Reverse engineering with Fronius Additive
Spare parts on demand
Supply shortages, discontinued spare parts, or missing CAD data invariably lead to production downtime. When critical components fail, their delivery time affects the productivity of entire plants.
We analyze, digitalize, and reconstruct defective or obsolete original parts and use Fronius Additive to manufacture new components that match the originals as closely as possible. Our Prototyping & Manufacturing Center has the entire process chain covered. The advantages for you include start-to-finish quality assurance and certified component approval—all from a single source.
A ready-to-use component in just four steps

Model qualification
Additive-manufactured pressure containers
The entire process chain has been considered for this component, from the design to the final testing and the CE label. The draft European standard prEN 13445-14 was used as the basis for the model qualification. The report on the entire process offers a vivid insight into the performance of metal-based additive manufacturing using arcs.
