Technical Specifications & Codec Breakdown
STL for 3D Printing, OBJ & GLTF for Digital Art
STL stores raw triangular mesh surfaces with zero color or texture data - perfect for 3D slicing software and 3D printers. OBJ and modern GLTF store vertices, normals, UV texture coordinates, and materials for video games and web 3D.
GLTF: The JPEG of 3D Graphics
Khronos Group designed GLTF to be the compact, web-ready 3D standard. Unlike heavy CAD files, GLTF packs geometry, shaders, and animations into a streamlined binary container that loads instantly in web browsers.
