The Original Prusa Core One L+ is a large-format CoreXY 3D printer with a 300×300×330 mm build volume and an actively heated chamber reaching up to 60 °C. It arrives factory-calibrated, handles over 200 verified material profiles, and only about 5 minutes stand between unboxing and your first print. The ideal companion for workshops, small-batch production, and advanced makers who need to print large functional parts without warping or splitting them into pieces.

Double the build volume compared to Core One

The Prusa Core One L+ offers a build area of 300×300×330 mm, which equals 29.7 litres of net volume. That is double the standard Core One and means the end of splitting large models into parts, gluing, and sanding seams. Cosplay helmets, film props, manufacturing jigs, and large mechanical components can be printed in one piece - from edge to edge of the print bed.

Heated chamber up to 60 °C

The actively heated chamber with temperatures up to 60 °C is the key to trouble-free printing with engineering materials. ASA, ABS, polycarbonate, and nylon filaments stop warping, corners no longer lift off the bed, and layers bond firmly together. The result is durable prints without cracks or delamination.

New heated bed with dual-loop heating

A massive aluminium bed with a dual-loop heating system ensures even heat distribution across the entire surface. While other large printers struggle with lifting corners, the Core One L+ keeps models firmly attached from edge to edge. Convective heating also stabilises the chamber environment even for the most demanding polymers.

CoreXY kinematics and Input Shaper

CoreXY kinematics combined with Input Shaper and Phase Stepping enable high print speeds without loss of quality. The new GT1.5 belts suppress repetitive surface patterns that are usually visible on large smooth areas. The result is a smoother surface that you can use straight away as a final product.

Ready for 200+ materials

The printer handles a complete range of common and advanced filaments. It effortlessly prints PLA and PETG for everyday use, as well as engineering materials including carbon-filled composites. Printing with flexible materials is also supported - just switch the sensor to flex mode and start printing.

Optional HT Hotend upgrade for printing up to 400 °C

With the HT Hotend upgrade, you can reach nozzle temperatures of up to 400 °C, which opens the door to truly industrial polymers such as PEKK-CF, PPS-CF, PPSU, or PPA-CF. These materials can replace metal parts thanks to their strength, at a fraction of the weight and cost compared to CNC machining.

Extreme overhangs up to 75° without supports

Optimised airflow and a precisely tuned print profile allow you to print overhangs of up to 75° without supports. You save material, time, and post-processing - no support removal, no marks on the underside of the model. On large models, this can mean savings of several hundred grams of filament per print.

Complete offline operation and security

The Core One L+ can be fully operated entirely offline. Slicing, firmware updates, and file transfers can all be handled via USB without any network connection. The Wi-Fi module is removable - a feature appreciated by government agencies, the defence sector, and companies working with sensitive data. There is also a special version for critical infrastructure without Wi-Fi provisions and without cameras.

Factory-calibrated, prints in 5 minutes

The printer arrives fully calibrated, including Input Shaper and Phase Stepping. Just unbox it, connect the display, choose a language, and press print. From opening the box to your first functional print, only about 5 minutes stand in your way - no tests, calibrations, or tuning.

Ready for the INDX Toolchanger (up to 8 tools)

The printer can later be expanded with the INDX system developed in cooperation with Bondtech. It allows you to combine up to 8 different colours or materials in a single print with lightning-fast tool changes and almost no waste. Your investment in the Core One L+ therefore grows together with your needs.
