Technology & Products

Key Products

Additive manufacturing services using the patented Metal Powder Application (MPA) process (cold-gas spray + 5-axis machining) for multi-material metal parts with conformal cooling and heat-transfer inserts.

Technological Advantage

Enables the combination of dissimilar materials and the creation of internal cooling channels in parts up to 550 mm diameter and 600 kg, avoiding the heat-affected zones of laser-based processes.

Differentiation

Value Proposition

Combines supersonic metal deposition with precision 5-axis milling to produce fully dense, multi-material parts (e.g., copper-in-steel) with internal conformal cooling channels, reducing lead times for complex tool and mold making.

How They Differentiate

Utilizes kinetic thermal spray (MPA) rather than laser-based melting, allowing for significantly higher deposition rates and multi-material builds without thermal stress or welding-related issues. They also differentiate through their focus on high-performance, highly innovative 5-axis machining centers, offering precision, performance, and reliable service.

Why this company matters

AMPulse analysis, not a company disclosure

Hermle Maschinenbau, a German Mittelstand company founded in 1938, occupies a distinctive position in industrial manufacturing by integrating additive and subtractive processes in a single machine. Its patented Metal Powder Application (MPA) process uses a supersonic jet traveling at three times the speed of sound to deposit metal powder at 10 GPa pressure and temperatures up to 1,000°C. This kinetic compaction method avoids the heat-affected zones and thermal stress common to laser-based powder bed fusion or directed energy deposition, enabling the combination of dissimilar materials such as copper-in-steel in a single build.

The MPA 40 hybrid machine can produce parts up to 550 mm in diameter and 600 kg, with internal conformal cooling channels that are difficult or impossible to achieve with conventional machining or laser AM. After deposition, the machine switches to precision 5-axis milling for final surface finish and tolerances. Hermle targets existing machining center users and manufacturers in medical technology, optics, aerospace, automotive, and tool and mold making. Notable customer M&L Precision Machining Inc. uses the technology for medical devices, aerospace, and defense components.

Hermle's approach competes with laser-based hybrid systems from DMG Mori and others, but its kinetic spray process offers higher deposition rates and the ability to bond dissimilar metals without welding defects. The company has invested in AM R&D for over a decade, maintains roughly 20 dedicated AM engineers, and distributes its additive services through partners like Kingsbury. A key open question is whether the MPA process can scale beyond tooling and mold applications into higher-volume production for aerospace or automotive tier-1s, where laser-based metal AM is already established.
