Vertical step test

thingiverse

This small test model is designed to evaluate vertical layer shifting in your 3D printer. It can be used to assess physical resolution, software resolution, and slicer performance. It consists of a simple rectangle made up of fifty-one smaller rectangles that increment from 1mm to 2mm by 0.02mm steps. Two rows of steps are present for easier evaluation. Markings every 0.2mm make it simpler to judge the current position. You can scale this model in the x and y planes for your convenience. Scaling in the z plane will, naturally, affect the heights and the markings will no longer be accurate. However, this may still be useful for further resolution testing. Note the photo showing that a 0.12mm test produced smooth rectangles, while a 0.10mm test resulted in artifacts (visible as pencil lines on the model). My printer is a Monoprice Maker Select Plus (Wanhao I3) and the models were sliced using Cura 3.5.
