3D printers · Maintenance
This section is limited to published 3D printers models and tasks. Follow model-specific cleaning, inspection and replacement guidance with clear stop conditions.
Creality
The U.S. K2 Plus specification lists a 350 × 350 × 350 mm nominal build envelope. Check the complete job in the K2 Plus slicer profile, not just the imported part’s longest dimension. The specification does not provide a universal safe clearance for every geometry.
Bambu Lab
The A2L bed is rated to 80°C and the nozzle to 300°C. These are separate hardware ceilings, not recommended settings for every filament. Bambu Lab lists PLA, PETG and other non-engineering filaments for this printer.
Prusa
For MK4S toolhead care, identify the installed nozzle before choosing a procedure. The standard configuration uses a 0.4 mm high-flow brass CHT nozzle, and Prusa excludes high-flow nozzles from its needle-cleaning method. The 290°C nozzle and 120°C bed maximums are ratings, not cleaning targets.
