Discrepancy between design and actual measurements. Approach from both mechanical adjustment and slicer settings.
Too high flow rate makes prints larger, too low makes them smaller.
Loose X/Y axis belts reduce positioning accuracy, causing dimensional errors.
Variations in nozzle or bed temperature change shrinkage rate, causing dimensional errors.
Wrong printer steps/mm settings cause overall dimensional errors.
Measure with calibration cube and adjust.
Ensure positioning accuracy with proper tension.
Maintain constant temperature to stabilize shrinkage.
Set accurate movement for each axis.
Adjust dimensions with slicer compensation.
Uniform shrinkage with appropriate cooling.
Print a 20mm × 20mm × 20mm cube.
Measure each side with calipers and record errors.
New flow rate = Current flow rate × (Design value / Measured value)
After adjustment, print cube again to verify.
Low shrinkage, good dimensional accuracy
High shrinkage, difficult dimensional control
