STL

Stereolithography

The STL file format is a widely used standard for representing 3D models, primarily in 3D printing and computer-aided design (CAD). It is supported by most CAD software, 3D modeling tools, and slicing programs like Cura, PrusaSlicer, and Simplify3D. The format stores surface geometry as a collection of triangular facets, defined by vertices and normals, but lacks advanced features like color, texture, or metadata, making it simple yet limited for complex applications.

ICO

Microsoft Icon File

The ICO (Icon File) format is a widely used image file format primarily designed for storing computer icons in Microsoft Windows operating systems. It is supported by various graphic editing tools like Adobe Photoshop, GIMP, and online converters, as well as being natively compatible with Windows for displaying application and system icons. The format can store multiple images of varying sizes and color depths (up to 32-bit RGBA) within a single file, allowing for high-quality, scalable icons with transparency and anti-aliasing support.
