All-in-One Calibration Test + Full Guide

by Kitch 3Ds

Full guide in the description, read before printing! This test model was originally created by Autodesk & Kickstarter in collaboration with Andreas Bastian. I'm sharing it here on MakerWorld with a simplified guide because the original documentation can be hard to follow. All description images are from the original guide. My print photos are the white model.Original model and full documentation: https://github.com/kickstarter/kickstarter-autodesk-3d This guide is optimized for PLA/PLA+. PETG users may see different results - see notes where relevant.To get the most out of this test, you will need a caliper (or at least a ruler). Print time is approximately 2 hours depending on your filament and settings. Print without supports. For best results use a standard speed profile and 0.2mm layer height. Make sure your first layer is well calibrated; on Bambu Lab printers use the Z offset slider on screen or in Bambu Handy, or run Auto Bed Leveling from Device > Calibration. A bad first layer affects multiple tests simultaneously.For Bambu Lab printer-specific guides, visit the official wiki at wiki.bambulab.com and search for the relevant topic (flow rate calibration, retraction, vibration compensation, belt tension) filtering by your printer model. 1. Dimensional AccuracyMeasure each tier of the dimensional accuracy section with calipers, then compare the printed value to the expected digital dimension. Do this for both X and Y axes.Good result: printed dimensions match digital values within ~0.2mm.If not: a consistent error on both axes means your flow rate or extrusion multiplier needs calibration. A significant difference between X and Y specifically indicates backlash (mechanical play in the motion system) → check belt tension. In Bambu Studio use the Flow Rate calibration tool under Device > Calibration.BambuLab Official Guide → https://wiki.bambulab.com/en/software/bambu-studio/calibration_flow_rate 2.
