Here are some resources for visualization and 3D printing, including free and licensed resources. The Library also offers free 3D printing through the Digital Media Lab. You can reserve time for one of the printers, up to 3 hours/day.
Open repository of 3D biomedical printing files, including small molecules, proteins and other macromolecules, viruses, bacteria, and anatomical models, as well as tutorials to help you print your models. You can also upload 3D-printable files for others to use, and pictures of your printed objects.
Web-based 3D viewer for chemicals and macromolecules, with the ability to export VRML and STL files for 3D printing. Can open files by ID number (including PDB and PubChem CIDs), plus PDB, MOL2, mmCIF, and SDF files.
Part of the Cambridge Structural Database System. Visualization program for 3D crystal structures. You can load search results from ConQuest, or open from a file (including .cif, .mol, .pdb). Files can be saved as images, animations, third-party formats (.cif, .mol, .pdb), and 3D printing files. [More about Mercury]
Database of +193,000 inorganic crystal structures, with crystallographic data and journal citations. Jmol embedded for visualizing structures, which can also be downloaded (.cif).
Web-based access to searching the Cambridge Structural Database, without downloading ConQuest and the rest of the CSD System. JSmol embedded for visualizations, and structures can be downloaded (.cif).
Repository of structural information on biological macromolecules, including proteins and nucleic acids, +140,000 records. Structures can be visualized, downloaded, and deposited. See also: Nucleic Acid Database
Open access collection of crystal structures from organics, organometallics, inorganics, and minerals - +390,000 entries. Structures can be viewed in JSmol and downloaded (.cif).
NCBI's structure database. From the MMDB summary record, you can view and download the structure (PDB, PNG etc.) or open the structure in the full iCn3D viewer for additional viewing options and creating 3D-printable files.
