The Aliaser

thingiverse

This is a grueling trial for resin-based DLP/LCD/Masked SLA printers that push them to their limits on every vertical surface. Each one presents a pathological challenge for the pixel array, resulting in pronounced aliasing artifacts across multiple dimensions. This rigorous testing allows for an in-depth examination of how LCD resolution affects aliasing artifacts and enables the evaluation of various antialiasing methods. The test comprises: - One spherical surface with a radius of 400mm - Two cylindrical surfaces with a radius of 200mm - one aligned parallel to the LCD, the other perpendicular - Three planes with normals at a 2-degree angle from the LCD grid - one tilted in the Y direction and two in the X direction (one tapered leftward and the other rightward) This test requires approximately 7ml of resin. Print this model in the specified orientation provided in the STL file. It is highly recommended to print with opaque resin to facilitate interpretation of the results, but it is not strictly necessary.
