The NIH 3D Print Exchange hosts web-based tools that automatically generate 3D model files from 3D molecular and medical imaging data. Each workflow creates a set of downloadable model files that are scientifically relevant and optimized for 3D printing. Click here to learn more.

Use the Quick Submit tool on the right to automatically generate models from PDB, EMDB, or PubChem by simply entering a database accession code.

If you have your own 3D data file, choose the appropriate workflow below, upload your file, and submit your entry. You must publish your model before it can be downloaded.

Visit the Share page to upload your own printable models in STL, WRL, or X3D format.

Quick Submit

Please Login to enter a database accession code and generate a 3D-printable model of a structure in the Electron Microscopy Data Bank, Protein Data Bank, or PubChem.

  • Small Molecule Models

    Small Molecules

    Generates atomic ball and stick, stick, and sphere representations of chemical structures with fewer than approximately 1000 atoms. Supports CIF, MOL, MOL2, PDB, and SDF file formats.

  • Molecular Models


    Generates ribbon and surface models for proteins, polynucleotides, and other large biomolecules. Recommended for systems with greater than 200 atoms. Supports PDB, PDB1, CIF, ENT, GRO, MAE, MOL, and MOL2 file formats.

  • Cell & Organism Models

    Image Stacks

    Generates surface models from confocal image stacks and electron microscopy maps. Supports MAP, OMAP, and OME-TIF file formats.

  • Medical Imaging Models

    Medical Imaging

    Outputs bone structures from CT scan data in zipped DICOM format; results may vary with MicroCT. Not recommend for MRI or other modalities. DICOM files are stripped of personal information and are hidden from other users by default.
