📍 Part of our comprehensive guide: Ultimate List of 3D Model Sites
The Smithsonian 3D Digitization Program (3d.si.edu) is the world’s premier open-access cultural heritage and museum 3D repository. Bringing together digitized artifacts from the 21 Smithsonian museums, national research centers, and the National Zoo, Smithsonian 3D provides authentic, laser-scanned 3D models of dinosaur fossils, Apollo 11 command modules, historical aircraft, and American cultural icons for free interactive exploration and 3D printing.
Preserving World Heritage in Millimeter 3D Scans
The Smithsonian Institution houses over 155 million physical objects. Through the **Smithsonian 3D Digitization Program**, the institution utilizes industrial structured-light optical scanners, CT tomography, and aerial photogrammetry to create millimeter-accurate digital twins of irreplaceable historical treasures.
Anyone around the globe can explore the inside of Neil Armstrong’s **Apollo 11 Command Module**, examine the cranial sutures of a fossilized **Tyrannosaurus Rex skull**, or inspect the fabric texture of George Washington’s military uniform in their web browser.
Voyager 3D: Guided Educational Tours
Models on the platform are powered by **Smithsonian Voyager**—an open-source 3D WebGL viewer that features interactive guided tours, anatomical cross-sections, and curated scholarly articles written by museum curators and paleontologists.
3D Printable Educational Files
Every digitized object includes downloadable, manifold **STL files** scaled for educational classroom 3D printers, enabling students to hold exact replicas of historical artifacts.
