Calibration Cube optimized 20x20x20mm for resin printers 2024
Description
A revised version of the calibration cube for your 3D resin printer. Print this on the center of your build plate to verify/adjust that your scene is dimensionally accurate with your printer. No supports or rafts. Make sure your exposure and other settings are dialed in beforehand! Uses 4.5 mL or 5.4 grams of resin. Changes: - Thicker walls for better dimensional stability (easier measurement with calipers) - Updated drainage - Less suction - Oriented the correct way (drag, drop, print) - Easier removal from build plate (beveled underside) If the printed and cured cube is not exactly 20mm on all 3 axes, you must adjust your printer scene in your slicer software. In Lychee slicer this is called 'Scene Scale Compensation' and is adjusted for individual resin profiles. If the cube is too big, you simply reduce the percentage scale to adjust. Example: X axis measures 20.1 mm which is 0.1 mm oversized Calculation: 100 - (0.1mm/20mm) x 100 = 99.5% Type in 99.5% in X axis scene scale compensation. Cube too big = reduce scene scale. Cube too small = increase scene scale. In Chitubox and other slicers that do not have scene scale compensation in percentages, you must adjust your printer screen size dimension or similar setting. In Chitubox this is found under Machine settings. Example: If your printer screen size on the X axis is 125mm, and your cube measures 20.1 mm on the X axis (error of 0.5% as per the example above), you must then increase your printer screen size in the slicer by 0.5%. In this case: 125mm (screen X-axis) x 100.5% = 125.625mm (new screen X-axis) That tricks the slicer software to believe the bed is bigger, and scales down your models accordingly. Cube too big = increase screen size. Cube too small = reduce screen size.
