In 3D printing, achieving a level print bed is crucial for quality prints. However, there’s often confusion between ‘bed leveling’ and ‘mesh bed leveling.’ Although they sound similar, they have distinct roles. This post will clarify these terms and their significance in the 3D printing process.

What is Bed Leveling?

Bed leveling, or manual leveling, involves physically adjusting the print bed to ensure levelness relative to the extruder’s movement. This process includes adjusting bed screws or knobs at each corner of the print bed and using a leveling tool or paper to gauge the distance between the nozzle and the bed. It requires checking and adjusting at various points across the bed to ensure overall levelness.

What is Mesh Bed Leveling?

Mesh bed leveling is an advanced technique that often involves software and additional hardware like sensors. It compensates for bed surface imperfections by creating a ‘mesh’ map. The printer probes various points on the bed to map the bed’s surface and uses this data to dynamically adjust the Z-axis height during printing, compensating for irregularities. This method can achieve greater accuracy, especially for larger print beds.

Comparing the Two:

In terms of ease of use, manual bed leveling is straightforward but can be less precise and time-consuming. Mesh bed leveling requires initial setup but then automates much of the process. Equipment-wise, mesh bed leveling may need additional hardware like a BLTouch sensor.

Regarding suitability, manual leveling may suffice for smaller printers or less detailed prints, while mesh leveling is beneficial for larger beds and precision prints. In terms of maintenance, manual leveling might need more frequent adjustments compared to mesh leveling, which typically holds calibration longer.

Both bed leveling and mesh bed leveling are essential for successful 3D printing, catering to different needs. Manual bed leveling involves physical bed adjustment, while mesh bed leveling uses software to compensate for bed irregularities. Depending on your printer and printing requirements, one may be more suitable than the other.
