EOS showcased the M4 ONYX metal additive manufacturing system at the 2026 International Manufacturing Technology Show in Chicago. The system is designed to increase production throughput by 50% while reducing part costs by 30%.
Why it matters
The M4 ONYX addresses industrial scalability requirements through integrated automation, allowing manufacturers to maintain higher system availability and lower material waste. The system targets high-volume metal production environments where unit cost and speed are primary competitive drivers.
The M4 ONYX features a 450 x 450 x 400 mm build volume, with its FLX variant utilizing four 1.5 kW beam-shaping lasers to deliver a 50% throughput increase. The system incorporates RFS Pro filtration to achieve 90% powder material recovery and reduces quality assurance costs by 50%.
The players
EOS
A global leader in industrial metal and polymer 3D printing technology headquartered in Munich, Germany.
The details
The M4 ONYX platform employs a combination of homogeneous gas flow, active temperature control, and proprietary Smart Fusion software to manage thermal dynamics during the build process. A Grenzebach Dual Setup Station enables operators to complete job changeovers in under 30 minutes, while a Volkmann Automated Powder Handling system facilitates closed-loop delivery. The standard configuration utilizes six 400 W lasers, providing distinct options for scaling production based on specific geometry requirements.
Timeline
The M4 ONYX was displayed during the 2026 IMTS trade show in Chicago.
Market Landscape
The introduction of the M4 ONYX follows a trend of hardware launches at the 2026 International Manufacturing Technology Show focused on reducing the cost-per-part of additive manufacturing. This development extends the industry's shift from prototyping to high-volume industrial metal production.
Manufacturers evaluating the M4 ONYX should assess their current powder recovery rates and setup downtime to determine if a move to closed-loop automated handling will improve their margins. Compare these efficiency gains against your existing OEE benchmarks to verify if the 30% reduction in part costs is achievable in your specific application.
The takeaway
The M4 ONYX underscores the importance of minimizing manual intervention in metal 3D printing to achieve industrial-scale viability. Monitor your facility's job changeover metrics against the 30-minute industry benchmark to identify where automation could improve your throughput.
