XL

The XL is an FDM 3D printer from Prusa Research with a 360 x 360 x 360 mm build volume.

Specifications

Build Volume: The Prusa XL features an extra-large build volume of 360 x 360 x 360 mm (14.17″ × 14.17″ × 14.17″) [1, 2].

Kinematics: It operates on a CoreXY motion system on a sturdy aluminum frame, which provides high stability and precision for large prints .

Multi-Material: The printer utilizes a highly accurate toolchanger mechanism that supports up to 5 independent toolheads [1, 6, 7]. This allows for complex multi-material and multi-color printing with zero waste, eliminating the need for purge towers .

Hotend: Equipped with the Nextruder direct drive system, the hotend can reach a maximum temperature of 290°C .

Calibration

Here is a step-by-step calibration guide specifically tailored for the Prusa Research XL, covering hardware tuning, slicer settings, and model-specific quirks.

Step 1: Bed Leveling (Mesh Bed Leveling)

• Procedure: The Prusa XL uses a Loadcell sensor integrated into the Nextruder for fully automatic Mesh Bed Leveling , . It physically taps the 16-segment modular heatbed to measure distances and map the surface ,.
