Tinkercad Export Options
Exporting a design from Tinkercad for viewing, making, or sharing is easy. When you click “Export”, you have several options for the format in which you will export your design.
STL (an abbreviation of "stereolithography")
The universal format for 3D Printing. Choose the STL format if you are exporting for 3D printing. STL format format is supported by many other software packages; it is widely used for rapid prototyping, 3D printing and computer-aided manufacturing.
OBJ is an open format that is commonly used in 3D graphics applications. Use OBJ format for multi-color 3D printing.
The OBJ format export from Tinkercad produces a zip file with two files in it. One file describes the geometry (example.obj) and the other file describes the colors as applied in Tinkercad. (example.mtl).
Also written as glTF format, this export option minimizes both the size of 3D assets, and the runtime processing needed to unpack and use those assets. GLTF is becoming increasingly popular as a format for digital sharing and viewing workflows, such as on Sketchfab or Facebook
USDZ (iPad app only)
USDZ is a 3D file format that shows up as 3D or AR content on the native Tinkercad iOS app for iPads. Export this format from the Tinkercad iPad app, then send it to Mail, Messages, and other built-in iOS apps.
SVG (Scalable Vector Graphics)
SVG is a vector image format for two-dimensional graphics. Use this format for a lasercutting project, for example. When exporting this type from Tinkercad, the 2D vectors are generated where the 3D model intersects the default workplane location.
