NEW YORK, NY and GELDERMALSEN, Netherlands, Sep 10, 2025 – UltiMaker has launched its Secure Line of 3D printers, beginning with the S6 Secure and S8 Secure, to meet the demand for secure, decentralized manufacturing in defense and sensitive environments. The printers combine industrial-grade performance with security features that align with modern defense IT standards. Built for use across land, sea, and air operations, the Secure Line positions 3D printing as a tactical asset, enabling on-demand production of mission-critical parts while ensuring data protection and operational control.
“The Secure Line represents a strategic leap in making additive manufacturing a trusted and deployable asset for defense organizations,” said Andy Middleton, SVP EMEA and global marketing, UltiMaker. “By combining industrial-grade 3D printing with uncompromising security, the Secure Line enables the production of mission-critical components at the point of need, safely, reliably, and with full control over their data and infrastructure.”
Designed for operations in extreme and temperate conditions, Secure Line printers offer air-gapped, USB-only workflows, with no Wi-Fi, no external cameras, and no unverified third-party devices, eliminating common vectors for espionage, data theft, or remote intrusion.
Key security features include:
- Factory-flashed, tamper-resistant firmware
- Encrypted and auditable file handling
- Hardware-sealed components for field integrity
- No cloud dependencies or external attack surfaces
These features provide operational control and audit trails. They let defense teams produce mission-critical parts while maintaining data control, protection, and system security.
The S6 Secure and S8 Secure are engineered to bring industrial additive manufacturing capabilities from the lab to the field. With compact form factors and rugged construction, they enable:
- Reliable operation in mobile units, military bases, and naval deployments
- Rapid on-demand production of critical parts and tools
- Minimized downtime and reduced dependency on vulnerable supply chains
“With Secure Line, we give defense organizations something they have not had before: industrial 3D printers they can fully trust anywhere in the world,” said Arjen Dirks, CTO at UltiMaker. “We designed our Secure Line products with security built into every layer and to meet internationally recognized standards, combining reproducibility and long-term reliability in a form that guarantees tactical capability in defense environments.”
Powered by the UltiMaker Cheetah motion planner, high flow print cores, and a feeder system, S6 Secure and S8 Secure deliver up to 4x the productivity. The Secure Line supports complex applications by combining multi-material printing with engineering-grade materials available through the UltiMaker Marketplace, delivering material flexibility within a secure environment.
The Secure Line is manufactured at Zaltbommel, Netherlands, adhering to European standards for quality, data security, and compliance. NATO-aligned defense organizations have relied on UltiMaker’s 3D printing systems to produce parts for their operations. Each Secure Line product is manufactured in limited batches to meet defense industry requirements.
UltiMaker offers a two-year UltiMakerCare service with every Secure Line printer.
