or
STL, OBJ, PLY, 3MF, GLB, GLTF, FBX, AMF, VRML, 3Shape DCM, or a ZIP of them. Up to 750 MB per file.
Converted in your browser, never uploaded. Your files stay on your computer.
Output is always in millimeters. Source units only says what the numbers in your file mean.

Preview
Add a file to see it here in 3D.
Drag to turn, scroll to zoom, right-drag to pan. On a touch screen, use two fingers to turn and pinch to zoom; one finger scrolls the page.
Model lying on its side? Press Rotate. Only the preview turns; the converted file stays as it is.
About the converter
My 3Shape DCM says it is encrypted. What do I do?
Many DCM files from 3Shape are encrypted, and only 3Shape's own software can open those. In 3Shape, export the scan as STL, then convert that STL here. Unencrypted 3Shape DCM files convert directly.
A .dcm from a CT or X-ray machine is a different thing with the same extension: a DICOM volume, not a surface scan. It cannot be turned into a mesh here.
What does "Source units" mean?
Most 3D files store plain numbers with no unit attached. Source units tells the converter what those numbers mean in your file: pick the unit the file was saved in. Millimeters is right for almost every dental scan and design.
The converted file is always in millimeters. A 2 inch model saved in inches comes out 50.8 mm across.
If a file is marked "probably saved in meters", the model measures under 1 mm across, which a real dental model never does. Set Source units to Meters and its size is corrected.
Are colors and textures kept?
No. Only the shape is converted: the triangles that make up the surface. Colors, textures and materials are dropped, and a file with several parts comes out as one combined model.
Are my files uploaded anywhere?
No. Your files never leave your computer. The page loads the converter into your browser, and everything after that (reading, the 3D preview, building the new file) happens on your own machine. There is no upload and no server copy, so patient scans stay private.
Is there a size limit?
Up to 750 MB per file, and as many files as you like, read one at a time. Very large scans need a computer with plenty of memory, since all the work happens in your browser.
Stop downloading and converting scans by hand
With the Digital Bridge in LabNCloud, new cases from DS Core, Medit Link, DEXIS, Shining 3D and 3Shape come into one inbox for you to review, and their scans can be saved to your CAD folder, named for the patient and case. It is one part of the software that runs the whole lab: cases, invoicing, shipping and a doctor portal.
