This is a torture test for resin-based DLP/LCD/Masked SLA printers. Every vertical surface contains a pathological case for the pixel array, revealing significant aliasing artifacts in several dimensions. This is useful for investigating how LCD resolution impacts aliasing artifacts, testing various antialiasing methodologies, etc.
The test includes:
- One spherical surface (r=400mm)
- Two cylindrical surfaces (r=200mm) - one with its axis oriented parallel to the LCD and the other perpendicular.
- Three planes with normals at a 2 degree angle from the LCD grid - one tilted Y direction, and two in the X direction (one tapered toward the left and the other to the right).
This test consumes approximately 7ml of resin. Print this in the orientation provided in the STL. Recommended to print in opaque resin to aid in interpretation of the results, but it isn't strictly necessary.
Anycubic opaque UV resin
black or white
Highly recommended to use opaque UV resin to aid in vizualizing and interpreting the resulting artifacts.
