What adjustment can lead to better dimensional accuracy in prints?

Calibrating the printer is crucial for achieving better dimensional accuracy in 3D prints. Calibration involves adjusting various settings and components of the printer, such as the stepper motor settings, bed leveling, and extrusion multiplier. When these parameters are correctly set, the printer can produce more accurate and consistent dimensions in the finished model.

For instance, if the steps per millimeter for the extruder are not calibrated correctly, the amount of filament extruded may be either too much or too little, leading to discrepancies in the dimensions of the printed object. Similarly, proper bed leveling ensures that the first layer adheres correctly, providing a stable foundation for the rest of the layers, which can influence overall accuracy.

While lowering print speed, increasing infill percentage, or using a larger nozzle can have various effects on print quality, these adjustments do not directly address the fundamental issues of printer calibration. Adjustments like speed and infill can influence print time and strength but won't necessarily correct dimensional inaccuracies resulting from an improperly calibrated printer.
