Original Prusa CORE One L – großer Profi-3D-Drucker für anspruchsvolle Materialien

The Prusa CORE One L marks the consolidation of the new generation of professional 3D printers from Prusa. Constructed according to the same " Built to Last " principle, this version expands the build volume and sets new standards for Reliability, safety and productivity new in professional environments. With a Construction volume of 300 × 300 × 330 mm , one AC convection heating plate and one actively heated chamber up to 60 °C The CORE One L delivers the highest precision even with demanding technical materials.

A new statement

The CORE One L is more than just an enlarged version of its predecessor – it is a Statement . In a time when many manufacturers prioritize speed and connectivity over reliability, Prusa remains true to its claim of technological maturity and longevity loyal. Instead of adding underdeveloped features, the Czech manufacturer focuses on Well-designed, robust solutions that reduce maintenance and maximize uptime.

CoreXY design and advanced convection heating

The heart of the CORE One L is its CoreXY architecture , which combines structural rigidity and precise movements with a AC convection heating plate combined. This innovative system uses the heat of the print bed to heat the chamber evenly – completely without the risks of conventional PTC heating elements – and ensures a Temperature uniformity with less than 2 °C deviation . This allows technical materials to be printed with consistently high quality without warping or layer delamination.

Engineering for reliability

The CORE One L integrates clever mechanical solutions that reduce complexity and increase reliability. automatic ventilation system For example, it requires no motors or additional electronics: The printhead itself operates a mechanical lever to open or close the ventilation flap. This philosophy – “ less electronics, more reliability ” – is reflected throughout the entire device to ensure durability and maintenance-free operation.

Precise extrusion and automatic calibration

With the Nextruder direct drive extruder and a 10:1 translation ratio The CORE One L ensures precise filament feeding even at high speeds. 360° component cooling allows overhangs up to 75°, while the Input shaper technology It delivers vibration-free surfaces. The calibration of the first layer is performed. fully automatic – through a combination of force sensor, mesh bed leveling and phase control – for consistent results from the first print.

Enhanced security and multi-layered electronics architecture

The new AC-heated print bed This prompted Prusa to completely redesign the electronics. The printer incorporates a active voltage detection (110 V / 230 V) by analyzing the waveform in real time to optimize safety and heating performance. Furthermore, it features a Multi-layered safety architecture that monitors leakage currents and immediately disconnects the power supply in case of faults – with redundant TRIAC and relay circuits.

Data protection and offline operation

In a market that is increasingly relying on cloud platforms, Prusa reaffirms its commitment to Data protection and user control . The CORE One L can completely offline It can be operated – without an internet connection or account – and still retains all functions for setup, slicing, and firmware updates. The electronics are manufactured entirely in Europe, thus eliminating risks from third-party software or firmware manipulation.

Critical Infrastructure Edition

For environments with the highest security requirements, Prusa offers the CORE One L Critical Infrastructure Edition This version completely forgoes wireless connectivity and includes a Certified encrypted USB stick that enables a fully isolated and secure workflow – ideal for government agencies, defense and critical infrastructures.

Material compatibility

Thanks to the heated chamber and the AC convection plate, the CORE One L offers a exceptional material compatibility - from PLA, PETG and Flex up to ASA, PC, PP, CPE, Nylon and HIPS . With the optional advanced filter system, technical materials can be printed without distortion, with consistent dimensional accuracy and professional surface quality.

Software and open ecosystem

Like all Prusa printers, the CORE One L also works in a open and professional ecosystem :

• PrusaSlicer: Open-source slicer with over 200 pre-configured material profiles.
• EasyPrint: Direct slicing and sending via browser, smartphone or tablet.
• Prusa Connect: Secure remote management with job scheduling and notifications.
• Prusa App: For iOS and Android, it enables remote monitoring and control.

All software and firmware components are fully Open Source and enable offline operation, slicing, and updates without an account or internet access. Users also have access to over one million free 3D models on Printables .

A long-term investment for professionals

The Prusa CORE One L Prusa's new CoreXY platform establishes itself as the benchmark for Reliability, precision, and safety . Their combination of robust construction, open philosophy, and long-term support makes them the ideal tool for Print farms, workshops, design studios, and industrial applications . More than just an evolution, the CORE One L embodies what Prusa has always stood for: mature, reliable and productivity-oriented technology .
