Smithsonian 3D: check rights and formats before printing

What Smithsonian Open Access actually covers

The FAQ describes Smithsonian Open Access as a program intended to increase public use of millions of digital resources, including 2D and 3D images and data. It says Open Access items carry a CC0 designation and explains what that means for copyright. That alone does not establish that a particular 3D file is available, printable, or free of third-party rights.

The FAQ states that CC0 applies to copyright only: permission from someone else may still be needed. It also says some objects subject to limitations may have portions of their metadata released as CC0 without a media file provided by the Smithsonian. Separate the record’s designation, the media file’s status, and whether that file is actually available; the Open Access program name alone does not answer all three questions.

The FAQ says CC0-designated items do not require attribution or citation, but recommends a minimal credit with title, author, source, license, and source URL. That recommendation helps identify the item; it does not create additional rights. For general license concepts, see 3D file licenses and rights. This page focuses on checking a record and its files, not making a legal determination for a particular object.

Reading the CC0 designation on each object record

The FAQ gives an identification method: look for the Creative Commons Zero icon on Smithsonian websites or third-party sites redistributing the collection. It says an item without the CC0 designation is subject to usage conditions. Apply this check to the exact item; the collection landing page or program name does not establish the status of every 3D file.

After locating the designation, check what it applies to and whether the record offers a 3D file. The FAQ warns that some rights-limited records have CC0 metadata but no media file. Keep the record status separate from the file’s status, and check third-party rights before reuse.

For CC0 items, the FAQ says Smithsonian does not require a citation, but recommends a minimal caption with title, author, source, license, and source URL. Keeping those details can help locate the item and its page again. Before sharing a file or remix, also check conditions for the media and any third-party rights; the credit recommendation does not replace that check.

Available formats: glTF, glb, obj and Voyager scenes

The FAQ lists formats for Open Access 3D content: glTF, glb, OBJ in 150k and full-resolution versions, and Voyager scenes viewable online. It names these formats without specifying in this excerpt which software imports them, whether each file contains a closed mesh, or whether it is intended for fabrication. Check that the exact file is available and that your chosen software supports its format.

The FAQ names two OBJ versions, “150k” and “full res,” without recommending either for a particular print size or nozzle. Do not turn those labels into a ranking of quality, detail, or slicer performance without inspecting the file and your project needs. The sources cited here do not show that any specific Smithsonian object was prepared or repaired for printing.

If your chosen software does not directly accept a listed format, look for import instructions documented by that software before converting anything. The cited Smithsonian sources list possible formats; they do not prescribe OBJ as a universal import route or describe saving a repaired file as a 3MF project. The STL vs 3MF guide covers those formats separately; it does not replace documentation for the selected software and file.

Voyager is a viewer, not a printability guarantee

The Smithsonian/dpo-voyager GitHub repository describes Voyager as a browser-based 3D tool suite: Voyager Story for quality control and authoring presentations, annotations, articles, and tours; Voyager Explorer as a viewer component; and Voyager Mini as a minimal viewer optimized for size and loading speed. The repository says the software is pre-release, provided “as is,” and may undergo breaking changes. These descriptions concern the software, not the geometry of a specific cultural asset.

The repository describes Voyager Explorer as a 3D viewer. Browser visualization can help you look at an object on screen; it does not confirm that a downloadable file exists, that a mesh is closed, or that it imports into a slicer. The FAQ separately lists Voyager scenes as viewable online alongside 3D file formats. Treat the viewer as a visual presentation and check files and integrity separately.

The two repositories have different license scopes. Voyager’s GitHub page lists Apache 2.0 for the software. Smithsonian/OpenAccess describes itself as a metadata repository and displays CC0-1.0; it was archived on May 21, 2026, and its README says compressed archives have moved away from GitHub. These statements concern repository code and metadata, not automatically a cultural mesh’s rights or current media availability.

Inspecting and repairing the mesh on a copy

The Prusa Knowledge Base says models found online can be broken and that PrusaSlicer repairs them automatically to a certain degree, but not every corrupted model can be repaired that way. This is a general model-repair article; it does not say Smithsonian scans typically have these defects. Check the specific model and keep the original if you try a repair.

The Prusa article describes a Netfabb workflow in a Windows 10 context, using a warning symbol and repair command. That context does not establish current availability of the service or command in your installation. Before choosing a tool for the selected cultural file, check documentation for your version and the functions actually available. An older instruction is insufficient to recommend an installation or service today.

The Prusa page also illustrates repair limits with Meshmixer: Auto-repair does not always succeed, and Make solid can reduce resolution. These are documented descriptions, without current availability or a Smithsonian result verified here. For your own trial, keep the original file and record the software, version, selected action, and observed warnings. Then compare the result’s dimensions and appearance with the original; a warning disappearing does not validate every property of the part.

Scale, orientation and supports before you slice

Before slicing, compare the dimensions shown after import with your intended size and any reliable dimensions on the record. The cited Smithsonian sources do not state the file’s units or a default import scale. Do not choose a conversion factor from the extension alone; check the software’s import documentation and the exact media’s units. The unitless STL page addresses a specific STL question and does not establish the units of a Smithsonian asset.

Inspect the geometry and software warnings before choosing orientation or supports. Voyager viewing and an online scene do not certify mesh integrity or print settings. Prusa’s repair article describes methods that may fail or reduce resolution; it does not prescribe orientation or cuts for Smithsonian objects. Make those choices only after examining the specific file.

CC0 concerns copyright; it does not validate a mesh or its mechanical properties. Keep the record URL, designation associated with the media, and any displayed third-party conditions together. The FAQ recommends a minimal caption to identify the source even though attribution is not required for CC0 items.
