GO BIG WITH THE ORIGINAL PRUSA XL!
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. Pre-order information:Original Prusa XL shipping is scheduled to start Q3 of 2022. Reserve your place in line by paying the refundable deposit. Once your order is about to be shipped, you will receive a notification with the option to edit your order - select a specific XL version, add accessories, add-ons, filaments, etc.
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! Prusa's 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 Prusa's 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 Prusa's plans for the tool changer and the benefits of various nozzle sizes can be found at Prusa's blog article.
With eight times larger print volume compared to the MINI+, no project is too big for the XL!
Introducing the Nextruder!
Say goodbye to Live Adjust Z!
When designing the XL, Prusa 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 Prusa's 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. Prusa also added another thermistor into the heatbreak, which allows us to adjust the temperature according to the material specs and also detect heat creep.
