Industry standard for precise 3D solid model exchange between CAD systems.
IGES .igs .iges NURBS surfacesLegacy NURBS surface format widely supported by aerospace and older CAD systems.
STL .stl Mesh — 3D printingThe universal 3D printing format — simple triangle meshes readable by every slicer on the market.
OBJ .obj Mesh + UVVersatile mesh format with UV texture coordinates — the go-to for rendering and visualization.
3MF .3mf Mesh + color + metadataModern 3D printing format with color, material, and multi-part support — better than STL in every way.
glTF / GLB .gltf .glb Mesh + PBR — web/ARThe web standard for 3D — PBR materials, compact size, and native AR/VR support.
FBX .fbx Mesh + animationThe game and VFX industry standard for animated assets — mesh, skeleton, and animation in one file.
VRML .wrl Mesh + color — web 3DEarly web 3D standard — color meshes and scene hierarchy for virtual worlds and industrial viewers.
DXF .dxf 2D/3D — CAD/CNCAutodesk universal CAD exchange format for 2D drawings, laser cutting, and lightweight 3D geometry.
