In collaboration with the University of Alabama, we are creating a public on-line repository for 3D printable structure files (.stl and .wrl). We used Jmol to prepare ~30,000 molecules and solids in .wrl and .stl format! More information will be released at the upcoming 248th American Chemical Society Meeting in San Francisco, CA. See CINF Abstract # 125.

Overview
Over the past two years, we have been actively exploring 3D printed crystal structures. The
dodecaborate anion [B12
H12
]2–
, 9-Borabicyclo[3.3.1]nonane (9-BBN), and triphenylphosphine (PPh3
)
plastic models here today were fabricated on a Stratasys Dimension Elite 3D Printer.
How to Convert Crystal Structures into 3D Printable Files
There are many different methods and software packages that you can use to convert
crystallographic information files (.cif) into 3D printable files (e.g. stl and wrl). We have personally
used Jmol, UCSF Chimera, and Python Molecular Viewer with great success. Please see the
references below for a detailed explanation of the conversion process. Generally, it only takes a few
minutes to convert your crystal structure into a 3D printable file.
Current Efforts
We have been working towards creating a community of 3D printing crystal structure enthusiasts.
There is a listserv, [3DP-XTAL] hosted by the University of Alabama. If you would like to be added
to this listserv, simply email me at vfscalfani@ua.edu. We are also in the process of creating a 3D
printing crystal structure wiki/blog for the community.
In collaboration with the Royal Society of Chemistry, we are creating a public on-line repository for
3D printable structure files (.stl and .wrl). We used Jmol to prepare ~30,000 molecules and solids in
.wrl and .stl format! We are very excited about this project and will have more information at the
upcoming 248th American Chemical Society Meeting in San Francisco, CA. See CINF Abstract # 125.
