The Exposure Calibration Test

Stop wasting time marking your test prints with pens that wash away in IPA! This is a functional remix of the XP2 Validation Matrix by Photonsters

Key Improvements in this Remix

• Embossed Numbering (1-8): Each matrix features integrated numbers from 1 to 8. This allows you to run multiple exposure tests in a single print job and identify the best results instantly after curing.

• Elegoo Saturn 4 Ultra Grid: I’ve included a custom-designed plate layout for the Elegoo Saturn 4 Ultra. It provides perfect spacing to maximize your build area

• Original Accuracy: I have not touched the internal calibration geometries (pillars, holes, and lines). You get the trusted accuracy of the original Photonsters design with better workflow efficiency.

Instructions for Elegoo Saturn 4 Ultra Owners

1. Build Plate: 211,68 x 118,37 x 220 

2. Download the Grid (Grid Exposure Saturn 4 Ultra) : Use the provided layout to place 8 matrices on your plate.

3. Set Your Exposures: Assign different exposure times to each numbered tile (e.g., Tile 1 = 1.6s, Tile 2 = 1.8s, etc.).

4. Print & Compare: Once finished, you'll have 8 clearly labeled results to find your resin's "sweet spot" in under 15 minutes.

Note: The grid is for alignment purposes only; once you've placed your templates, you can remove the grid before slicing.
