STLSTL
Stereolithography
STL represents a model purely as a mesh of triangles with no color, material, or scale/unit metadata. It comes in ASCII and binary variants; binary is far more compact and is what most 3D printers and slicers expect.
Common Uses
OBJOBJ
Wavefront OBJ
OBJ is a plain-text geometry format storing vertices, normals, and UV texture coordinates. Materials (color, texture maps) are stored separately in a companion .mtl file rather than inside the .obj itself.
Common Uses
FBXFBX
Filmbox
FBX is Autodesk's proprietary interchange format for full scenes: geometry, materials, textures, cameras, lights, and skeletal (rigged) animation. It ships in binary and ASCII flavors and is the de facto bridge between DCC tools and game engines.
Common Uses
GLBGLB
GL Transmission Format Binary
GLB is the single-file binary packaging of glTF: geometry, PBR materials, textures, and animations are all embedded in one file, which makes it ideal for shipping assets over the web with no missing references.
Common Uses
GLTFGLTF
GL Transmission Format
GLTF is the JSON-based sibling of GLB: the scene structure is human-readable text, while binary geometry data and textures usually live in separate .bin and image files referenced from the JSON.
Common Uses
STEPSTEP
Standard for the Exchange of Product model data
STEP (ISO 10303) stores exact NURBS surfaces and solid boundary representations rather than a triangle mesh, so parts keep their true curved geometry and can be re-edited in CAD software after import. It has no concept of animation and only limited, rarely-used color support.
Common Uses
STPSTP
STEP File
STP is simply the shorter file extension used for STEP (ISO 10303) files on filesystems that historically limited extensions to three characters; the underlying format and exact CAD geometry are identical to .step.
Common Uses
3MF3MF
3D Manufacturing Format
3MF is a modern, ZIP-based 3D printing format created by the 3MF Consortium (Microsoft, HP, and others) specifically to replace STL's limitations — it supports full color, multiple materials, and multiple objects in one file.
Common Uses
USDZUSDZ
Universal Scene Description Zip
USDZ packages USD scene data, textures, and audio into a single, uncompressed zip archive (compression is intentionally disallowed by the spec so it can be memory-mapped directly). It's the format Apple's AR Quick Look uses to preview 3D content in Safari and Messages.
Common Uses
USDUSD
Universal Scene Description
USD is Pixar's open framework for composing large, layered 3D scenes from many collaborators — it supports non-destructive overrides, variants, materials, and animation, and underpins tools like Nvidia Omniverse.
Common Uses
DAEDAE
COLLADA
COLLADA is an XML-based scene format that was once an ISO standard for game and DCC interchange, supporting materials, textures, and skeletal animation. It has been largely superseded by glTF and FBX but is still accepted by many older pipelines.
Common Uses
PLYPLY
Polygon File Format
PLY (the Stanford Triangle Format) stores a mesh or point cloud along with per-vertex properties like color and normals, which is why it's the preferred output of many 3D scanners and photogrammetry tools.
