Prusa CORE One L: power, precision, and large format in a single machine

The new Prusa CORE One L is the most ambitious 3D printer in Prusa Research’s professional range. Designed for the production of large, precise parts, this large-format CoreXY machine combines thermal innovation, industrial reliability, and a compact design.

Its 300×300×330 mm print volume offers nearly double the capacity of its predecessor without compromising ergonomics. Thanks to its new cast aluminum heated bed, a homogeneous temperature is maintained across the entire surface (variations below 2%), ensuring perfect adhesion even for technical materials.

The AC convection ventilation and active air circulation system, using dual fans integrated beneath the bed, speeds up chamber heating up to 60 °C uniformly, eliminating cold spots and minimizing warping. Ideal for demanding polymers such as PC-ABS or PA12-CF.

The fully enclosed design with magnetic panels enhances thermal stability and printing safety. Inside, flexible filament management has been optimized through a new loading lever that prevents jams, making it easier to print with materials such as TPU 98A.

The extrusion system features the Nextruder extruder with 360° cooling, allowing overhangs up to 75°, while the Input Shaper technology maintains print quality even at high speeds. Technical materials can be printed without cracks or corner lifting, and filament loading is simplified via a flexible mode with a physical switch and dual sensors. The first layer calibration is fully automatic using a load cell, mesh bed leveling, and phase stepping; additionally, GPIO port and accelerometer compatibility make it a versatile platform for industrial environments.

Its electronics are based on a 32-bit board (xBuddy with STM32), Trinamic 2130 drivers, and 0.9° stepper motors, ensuring precision and control. The direct extruder, compatible with the E3D V6 module via adapter, includes 10:1 planetary gears, an all-metal hotend, and a high-performance turbine fan with a quick-swap nozzle system.

Factory-calibrated with two nozzles (one high-flow CHT brass and one wear-resistant, both 0.4 mm), this printer is optimized for print farms with minimal downtime and will be able to incorporate the MMU3 multi-filament printing system in early 2026.

Prusa3D also offers the Critical Infrastructure Edition, which places special emphasis on data security and process integrity. It includes a custom mainboard without Wi-Fi or wireless circuitry, no camera, and comes with a certified encrypted USB drive to ensure a fully offline workflow — ideal for environments where security is essential.

The CORE One L model comes fully assembled and factory-calibrated, offering a truly professional experience. Its reinforced CoreXY architecture with high-rigidity components ensures high speeds without compromising quality. The machine also features an advanced air filtration system, available as an optional accessory.

Founded by Czech engineer Josef Prusa, the brand has become a benchmark in professional 3D printing. With over a decade of experience, its commitment to open innovation and European manufacturing has made it a global leader. The ISO 9001, 14001, and 45001 certifications reinforce its dedication to quality and sustainability.

The Prusa CORE One L is the ideal choice for engineers, laboratories, and production centers looking to print large parts in a single piece with millimetric precision and thermal stability. Its professional design, heated chamber, and optimized print profiles ensure industrial-level results.

Filament2Print, official Prusa distributor in Spain, will offer this model along with a range of complementary accessories such as the Magigoo Glide Kit and professional maintenance kits.

The Prusa CORE One L is now available for pre-order through authorized distributors. Discover how to take your 3D production to the next level with a machine built to think — and print — big.
