The XL comes with the brand new “Nextruder”, a completely redesigned extruder with a zero-backlash cycloidal gearbox, hot-swappable nozzles and a Load Cell-based system for fully automatic first layer calibration. No manual calibration, no Live Z adjustments. The XL achieves a perfect first layer across the entire surface every time you start a print.
The print quality is further enhanced by the XL’s modular bed design - instead of using a single large heatbed, which is prone to warping, the XL uses an array of smaller, individually-controlled segments. Only the necessary part of the heatbed is activated when printing smaller objects, making the XL energy-efficient. Just like other Original Prusa 3D printers, the XL also uses proven double-sided spring steel sheets with various types of surfaces, allowing for easy maintenance and effortless print removal.
And perhaps the best feature: the XL can be easily expanded to up to five tool heads thanks to a highly accurate tool changer with automatic calibration via the load cell sensor - no more tedious calibration prints! Our internally developed kinematic coupler mechanism ensures millions of trouble-free tool changes. Using multiple tool heads opens up new options for your 3D printer: easily print soluble supports, print with up to five colors, or print with vastly different materials. The tool heads will be available individually in our e-shop as optional upgrades - so you can start with a single-extruder XL and upgrade it gradually over time based on your needs. More information about our plans for the tool changer and the benefits of various nozzle sizes can be found in our blog article.
With eight times larger print volume compared to the MINI+, no project is too big for the XL!
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 zero-backlash cycloidal gearbox (20:1 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.
Built from the ground up, the Nextruder is a brand new extruder for Original Prusa 3D printers. Significantly lighter and packed with the latest technologies, including a zero-backlash gearbox and no-slip drive gear, the Nextruder is designed to deliver top-notch performance and amazing-looking 3D prints.
The XL is built around a sturdy aluminum extrusion frame, which makes the XL stable and rigid. Thanks to high-quality stepper motors, linear rails, and energy-efficient heatbed with 16 individually controlled segments, the XL delivers great-looking 3D prints up to 36×36×36 cm (14.17’’×14.17’’×14.17’’).
Large prints can easily take days to finish. However, you don’t need to worry about power outages. The XL features hardware-based power-loss recovery. In case of a power failure, the XL stores the last known extruder location, so when the power is restored, the machine can pick up exactly where it left off.
The Nextruder is equipped with the Load Cell function, which enables a fully-automatic first layer calibration without ANY user intervention. No adjustments, no tuning. Before every print, the XL measures the distance between the nozzle and the sheet with pinpoint accuracy, so it delivers a perfect first layer every single time.
Our internally developed multiplatform slicer comes with in-house made and fully tested profiles for all of our 3D printers and a wide range of filaments. With built-in tools, such as advanced support generation, cutting, automated object distribution, ironing and many others, you will turn your 3D models into print files in no time!
The XL is powered by a new 32-bit motherboard with an expansion port, allowing an easy upgrade to up to five tool heads. Featuring popular enhancements, such as one-click-printing and G-code preview, the XL is easy to configure and operate.
The XL is fully compatible with a wide range of various types of materials. No matter whether you want to print something for fun from PLA and flexible materials, or you need to produce durable prototypes from PETG, ASA, Polycarbonate and Polypropylene - the XL can handle them all with ease.
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.
