NIH 3D Release History

Version: 1.0

March 7th/2023

Welcome to the first official release for NIH 3D!

What's New?:


  1. The the 3D Print Exchange has been rebuilt from scratch and re-branded as NIH 3D
  2. Site philosophy has been changed to embrace the upload and output of files that are suitable for 3D Printing AND/OR for other visualization technologies (eg. AR, VR, Animation...)
  3. All input files, metadata, and x3d outputs have been migrated from the NIH 3D Print Exchange. We have also migrated the .zip outputs that package the .wrl, .x3d and .stl files. In some cases we had to modify entries in order to be accomodated by our new system. If this required a file replacement, the original file has been attached as supplementary data. In some cases files were renamed but the data left untouched, in which case the old file was not included in the supplementary data.
  4. User accounts from 3D Print Exchange have only been migrated if the user had created models or builds, commented on the site, or been listed as a contributor to a 3D Print Exchange Entry. This was part of an effort to remove spam accounts from the site. You can easily create a new account from the sign-in
  5. You may now create an account using Google Sign-In OR e-mail/password
  6. All 3D Print Exchange entries have been stored as v1.0, then the input files have been re-run through our new workflows to generate v2.0. You may notice differences bewteen the outputs on 3D Print Exchange and NIH 3D due to changes in the software underlying our workflows
  7. New and Improved Workflows
    • Moved from Chimera to Chimera X for generation of 3D models for Quicksubmits and molecular data files
    • Output several new 3D printable and non-3D printable representations of molecules
    • Our DICOM workflows use Simple ITK and VTK to generate bone models from CT data
    • DICOMs and any supplementary medical imaging files will be anonymized automatically.
    • Now accept and output GLB format files
    • Custom "mesh repair" solution for 3D Printing has been built in Blender.
  8. Completely redesigned submission and post-submission process for models and builds
  9. Modernized UI
  10. Robust Search Features
  11. Expanded list of metadata pulled from external databases for "Quicksubmits"
  12. Expanded list of metadata for users to annotate their entries
  13. Re-classification of models into new NIH 3D Categories: Biomacromolecules, Viruses, Small Molecules, Prosthetics, Anatomy, and Cells & Organelles

We expect to continuously be adding new features to the site, so stay tuned!
