About STL Format

STL (Stereolithography) is the standard file format for 3D printing. It represents 3D surface geometry as a mesh of triangles, without color or texture information. Supported by virtually all 3D printing software and services.

About APNG Format

APNG (Animated PNG) is an extension of the PNG format that supports animation. Unlike GIF, APNG supports 24-bit color and 8-bit transparency, producing much higher quality animations with smooth gradients.
