Original Prusa CORE One L Critical Infrastructure Edition

True Air-Gapped Mainboard

Hardware-Level Security Enforcement

This edition features a custom-manufactured mainboard. All Wi-Fi connectors and related wireless circuitry have been physically removed, not just disabled via software. This provides a true, verifiable air-gapped solution, eliminating the attack vector of a network-connected device and ensuring full functionality in a 100% offline environment.

Secure Offline Workflow

Designed for Classified Data Handling

This bundle is built for a complete offline workflow. It supports an optional certified, encrypted USB drive for secure data transfer that is compatible with the platform. The machine ships with no camera, ensuring no optical data can be captured.

Large-Format, High-Performance Printing

Double the Build Volume for Demanding Projects

This machine delivers the full performance of the CORE One L. The massive 300x300x330 mm build volume allows for the creation of large functional parts, production fixtures, and full-size prototypes in a single piece. This enables rapid iteration and production of end-use components without compromising security.

Flawless Precision

What You Design is What You Get

The printer delivers on the promise of "What You Design is What You Get". Its rock-solid exoskeleton frame and precision kinematics ensure outstanding dimensional accuracy, as proven by CT scans. This precision is critical for industrial applications, guaranteeing that printed jigs, fixtures, or end-use components fit together perfectly as designed.

Optimized High-Speed Performance

Speed Without Sacrificing Structural Integrity

The robust CoreXY kinematics, factory-tuned Input Shaper, and high-flow nozzle deliver exceptional speed. However, performance is never sacrificed for speed records. Our internally-tuned print profiles are optimized for structural integrity, ensuring that all parts (even those printed at high speed) are solid, durable, and possess excellent layer adhesion, not brittle parts that crumble.

Simplified Flexible Filament Printing

Dedicated Path for Engineering-Grade Flexible Filaments

Printing with flexible materials is streamlined via a dedicated physical switch. Toggling this switch bypasses the primary filament sensor and opens a wider, less restrictive path for flexible filaments. This simplifies the loading of advanced flexible materials, while a second sensor in the print head maintains runout detection.

AC Convection Heatbed

Effortless Printing of Advanced Materials

The new AC heatbed is precision-milled from a thick block of aluminum, providing perfectly uniform heat distribution from edge to edge. This eliminates warping and cold corners. Two fans on its underside create a convection effect, rapidly heating the chamber up to a stable 60°C. This is the key to reliably printing demanding, high-performance materials like PC, ASA, or PA (Nylons) without warping or cracking.

Multi-Layered AC Electrical Safety

Redundant Hardware-Level Protection

The high-performance AC heatbed is protected by a multi-layered safety architecture. The system actively monitors for fault currents, similar to a residential RCD, and will immediately cut power if a leak is detected. This is backed by a redundant switching design using both a relay and a TRIAC, ensuring a hardware fail-safe if one component fails. The system is reinforced with a robust, shielded cable for the AC heatbed.

Zero-Setup Deployment

Unpack, Plug In, and Print

The CORE One L is a true "Unpack & Print" machine. It arrives fully assembled and pre-calibrated from the factory. There are no complex self-tests or calibrations required. The machine can be deployed and operational in minutes, streamlining the onboarding of new operators or integrating the unit into an existing production line with maximum efficiency.
