Defense-grade security and control

The UltiMaker Factor 4+ Secure pairs the high-speed industrial performance of the Factor 4+ with a hardened, air-gapped architecture built for defense, government, and other high-security environments where data control is non-negotiable.

• Air-gapped, USB-only workflow — no Wi-Fi, no Ethernet, no cloud endpoints, and no onboard camera, eliminating the most common network attack surfaces.
• Tamper-resistant firmware — factory-flashed firmware with encrypted file handling to guard against unauthorized access and data exfiltration.
• Operational sovereignty & data protection — complete ownership of files and print processes with no external network dependencies, keeping intellectual property and mission data fully under your control.
• On-demand field manufacturing — produce tools, fixtures, spare parts, and mission-specific components on site, reducing supply-chain dependencies and downtime.
• Compliance & procurement fit — engineered to meet rigorous NATO-aligned and defense-oriented standards with verifiable traceability and sustained support.

Built for the factory floor

Downtime is not an option in continuous production. The Factor 4+ pairs a redesigned, field-proven H-bridge gantry with a direct-drive dual-extrusion print head, a triple-insulated and actively temperature-controlled build chamber, and an automated material handling system. The result is consistent output even on complex, challenging geometries, job after job.

Core benefits

• Maximum throughput, zero compromise — up to 2× faster than the original Factor 4, driven by the Cheetah motion planner and the new high-flow AA+ and CC+ print cores.
• Built for 24/7 industrial cycles — a newly redesigned gantry absorbs vibration at high print speeds and was lifetime-tested for 15,000 hours of operation.
• Part-level confidence with UltiMaker TRACE — continuous logging and analysis for traceable, compliance-ready output.
• High-flow extrusion — push advanced polymers and composites through the system faster than ever, with flow up to 34 mm³/s.

UltiMaker TRACE — Technical Reporting And Certification Engine

TRACE goes beyond basic print monitoring to deliver the traceability that rigorous industrial compliance demands. Throughout every print job it continuously logs and analyzes four key parameters — extrusion factor, nozzle temperature, chamber temperature, and build plate temperature — so minor thermal or volumetric deviations that could affect part quality, layer adhesion, or mechanical performance are detected in real time.

High quality, every time, anywhere

A fully isolated, thermally controlled print chamber maintains a constant thermal gradient across the entire build envelope. By managing ambient temperature precisely, the Factor 4+ minimizes internal stress and thermal shock as each new layer is deposited — for accurate, reliable parts wherever the printer is installed.

• Actively controlled build-volume temperature up to 70 °C
• Heated flexible PEI build plate up to 120 °C
• Print cores reaching up to 340 °C for high-temperature materials

Engineered for production

• Integrated HEPA H13 filter — independently tested to remove up to 95% of ultrafine particles for cleaner air and better print quality inside the fully enclosed chamber.
• Automated material handling — automatic pre-loading and spool switching across up to 6 bays, with the storage chamber held below 15% relative humidity in any external conditions.
• Emergency stop — a prominent red STOP button immediately halts motion and heat sources when needed.
• Improved, lifetime-tested gantry — validated through 15,000 hours of rigorous testing for maximum field uptime.
• 7-inch capacitive touchscreen — mounted higher for a better view of the first layers, with high-resolution remote monitoring via UltiMaker Digital Factory.
• Dual onboard processors — ample computing headroom for current workflows and future updates.

Repeatable results across a wide range of materials

Edge-to-edge dual extrusion across the flexible PEI build plate, fast parts removal, and verified dimensional accuracy combine to deliver dependable production output. The Factor 4+ ships with new high-flow AA+ (0.4 mm) and CC+ (0.6 mm) print cores and remains compatible with the full family of UltiMaker swappable print cores.

• Easy to print: UltiMaker PLA, Tough PLA, PETG
• Mechanical strength: UltiMaker ABS, PC, Nylon
• Flexibles: UltiMaker TPU 95A, Tectonic-3D ANASA TPC 95A & L80A
• Reinforced composites: UltiMaker Nylon CF Slide, PET CF, PPS CF, Tectonic-3D Zephyr PA11 CF MC
• Heat resistance: UltiMaker CPE+, Tectonic-3D Vulcan PEKK-A, Tectonic-3D Kratir PA6/66 CF

Seamless software integration

UltiMaker Cura and the Factor 4+ Secure provide an easy, secure, USB-based workflow — from 3D model to finished part, with no cloud or network dependencies.

• UltiMaker Cura — powerful slicing with 400+ settings, application intent profiles, material interlocking, and sequential printing for small-batch production.
• Secure, offline workflow — air-gapped, USB-only print preparation and transfer, with no cloud connectivity or onboard camera.
• Onboard print process reporting — in-depth validation of part quality and structural integrity after every job.

Service and modularity

The Factor 4+ was designed to be modular, so a serviceable part can be swapped quickly to minimize production downtime. Under UltiMaker Care service plans, expert technicians and a global network of service providers help keep the printer running with high uptime.

Available print core options

AA, BB, CC, DD, and HT print cores are sold separately.
