Original Prusa XL 3D Printer - Semi Assembled

The Original Prusa XL is a large-scale CoreXY 3D printer with a build volume of 36×36×36 cm (14.17’’×14.17’’×14.17’’). Featuring an optional tool changer with up to 5 independent tool heads, automatic first layer calibration for an always-perfect first layer, and many smart features, the XL enables you to print massive objects with ease!

Introducing the Nextruder!

Say goodbye to Live Adjust Z!

When designing the XL, we left no stone unturned. The Nextruder is the new generation of 3D printer extruders. With built-in electronics, featuring a dedicated CPU and stepper driver directly in the print head, the Nextruder is controlled through a single-connector cable for easier maintenance. Fans, thermistors, the heater block and extruder motor - this all connects directly to the board inside the print head.

The completely redesigned extruder assembly allowed us to implement a fully automatic first layer calibration for an always-perfect first layer. Thanks to the internally-developed load cell sensor embedded within the heatsink, the XL can measure physical load in the heatsink and use the nozzle to probe the print surface. This way, the XL can utilize the load cell system to perform an incredibly precise height calculation for the first layer. No matter whether you just swapped the nozzle or the print sheet, there's no need to recalibrate anything. No Live Z, no manual adjustments. The XL delivers a perfectly smooth first layer every time you start a new print. The load cell sensor can do more, though! You can find more details in our blog post!

Filaments are no longer pushed by two small gears. Instead, we’re introducing a brand new planetary gearbox (1:10 ratio) with a large no-slip drive gear. This enables a higher level of control and also improves the compatibility with flexible materials. And there’s more: the nozzle and hotend are hot-swappable. The XL allows you to pull the entire brand new hotend assembly out of the extruder without the need to disassemble it. We've also added another thermistor into the heatbreak, which allows us to adjust the temperature according to the material specs and also detect heat creep.

Toolchanger

The XL can be upgraded with up to 5 individual print heads, each driven by its own electronics board. The internally developed toolchanger uses a reliable wear-resistant system and fully automatic tool alignment calibration ensuring millions of trouble-free tool swaps. This makes printing with multiple colors and with soluble supports quick and easy.
