Original Prusa XL assembled

Original Prusa XL

The Original Prusa XL is an open-source and open-material Core XY FFF 3D printer developed by Prusa3D was developed. Prusa3D is one of the most important companies in the 3D printing industry and the manufacturer of one of the most widely used 3D printers, such as the Prusa Mini, Prusa MK3S+ or Prusa MK4. The Prusa XL is Available fully assembled or partially assembled in three printhead variants : 1 printhead, two printheads or five printheads, and with or without the official Prusa case .

Prusa's 3D printers are characterized by their continuous innovation They strive to achieve the highest possible performance, with continuous updates and rigorous quality control. Over time More and more add-ons are being offered for purchase to fully exploit the potential of the Prusa XL, such as housings or additional nozzle diameters and materials, for example for printing with abrasive materials.

The Original Prusa XL has an impressive Construction volume of 360 x 360 x 360 mm and a cubic design for greater stability. The large building volume makes it possible to large objects in one piece and in one pass to print, which greatly speeds up the 3D printing workflow. The Prusa XL features numerous very attractive features that make it unique and efficient :

• Up to 5 independent printheads - a high-precision Toolchanger It allows printing with up to five colors or up to five different materials.
• Nextrudder - a newly designed extruder with a planetary gearbox, hot-swappable nozzles and a load cell-based system for fully automatic first-layer calibration.
• Modular print bed design - a series of smaller, individually controlled segments that reduce the risk of deformation and increase the thermal and energy efficiency of the printer.

All these features and more will be discussed in more detail below.

Features in detail

Nextruder and Toolchanger

The heart of the XL printer is The Nextruder, a lightweight, next-generation extruder driven by a planetary gearbox and equipped with various intelligent features, such as... a low-backlash cycloidal gear with a large, slip-free drive wheel (Advantage at flexible materials). In addition, the Nextrudder features an integrated CPU and a stepper driver directly in the printhead and becomes simpler maintenance controlled via a single connecting cable.

Another practical solution used in the Nextruder is the Custom breakout board . This means that all fans, heating elements, thermistors, etc., are directly connected to the board, and replacing any of these components takes only a minute. Furthermore, the integrated heatsink of the Nextruder allows for Load Cell function one Fully automatic calibration of the first layer Without any user intervention, settings, or adjustments, even after a nozzle or print bed change. Before each print, Prusa XL measures the distance between the nozzle and the print bed, which ensures that every print is perfectly aligned. a perfect first layer leads to... But that's not all the load cell sensor can do. It It can also detect a blockage in the nozzle. and interrupt the printing process.

With the Toolchanger, which is also based on the Load Cell Sensor, Prusa has once again pushed the boundaries of 3D printing . Thanks to the custom-developed tool changer system The Prusa XL can be equipped with a proprietary kinematic coupling mechanism. up to 5 individual printheads They can be upgraded, each controlled by its own electronic circuit board. The tool changer uses a reliable, wear-resistant system and a fully automatic calibration of the tool alignment , which enables trouble-free tool changes and efficient printing with Multiple colors, different materials and support filaments are guaranteed.

Chassis and body surface

The Prusa XL is based on a robust aluminum frame that supports the printer stable and stiff does. high-quality stepper motors, linear rails and an innovative heated bed are one of the reasons why the Prusa XL delivers such high print quality every time.

The Prusa XL build surface uses the proven solution from Double-sided spring steel sheets with different surfaces . These printing surfaces enable easy removal and maintenance and make working with Materials with different requirements for the building surface.

The modular heated bed The Prusa XL is a unique solution that leads to Increased efficiency of the printer. Unlike a large heated bed, as used in most 3D printers, the Prusa XL's heated bed consists of a series of 16 smaller, individually controlled 9 x 9 cm segments , which, thanks to the expansion joints between the individual segments, reduce the risk of deformation reduce. This solution also makes it very easy to heat only a specific section of the heated bed to adapt it to the size of the 3D printed part. This makes the Prusa XL Extremely efficient when printing small parts , reduces the load on the power supply and saves energy.

Connectivity, Prusa Slicer and UI

The Prusa XL printer is fully powered by Prusa Connect supported, a software that Prusa Connect allows the user to control the printer via an internet connection . G-code can be dragged and dropped into the browser window to first upload print files to the cloud (each user receives 2 GB free) and then transfer them to the printer's USB storage, allowing printing to be started remotely. All communication is encrypted . This function is particularly useful for 3D printer farms .

The Prusa XL is available via an LCD color screen and a clear user interface The Prusa XL is controlled with a redesigned menu for easier navigation and new, enhanced options such as a customizable user interface, an RGB status bar, dedicated preheating options, and more. A USB-A port for standard USB flash drives is located next to the LCD screen. The Prusa XL is fully compatible with Prusa Slicer software and comes with factory-tested XL print profiles.

Prusa XL grows with your needs

Due to its advanced features, large build volume and innovative efficiency solutions, the Prusa XL is suitable excellent as a primary printer For those who want to print large objects for modeling or functional applications using standard or engineering materials, with one or up to five different filaments, colors, or even support materials. However, the excellent connectivity options and versatility make the Prusa XL a great option for an additional printer as part of a 3D printer farm . possible applications There are countless options for the Prusa XL printer and will continue to grow thanks to the modular and upgradeable design of the Prusa XL .
