The Crystallography Open Database (COD) features more than 240,000 entries and has in recent years developed into the world’s premier open-access source for structures of small molecules and small to medium sized unit cell crystals [1]. The COD complements (rather than duplicates) with its coverage the well established open-access Worldwide Protein Data Bank [2]. The Cambridge Crystallographic Data Centre provides crystal structure data of small molecules for bona fide researches on a one by one basis for free [3]. There is also a project related to the COD that provides crystallographic open-access databases [4] (“COD offsprings”) for interdisciplinary college education. All of these databases store crystallographic information in the CIF [5] format. This contribution concentrates on open-access crystallographic databases for educational purposes [4]. Its aim is to share with fellow college educators how these databases may enrich materials science and engineering education. For example, utilizing two freely downloadable programs by Werner Kaminsky [5,6], we converted recently crystallographic information from CIF [7] to the standard STL format for 3D printing. Printed 3D models of the hexagonal and cubic densest packings as well as of the three cubic Bravais lattices have been obtained from Xerox with the help of Trevor Snyder and will be used by Peter Moeck in a 300 level “Introduction to Nanoscience and Nanotechnology course” [8]. Since CIFs are readily available over the Internet [1-4] for free, any interested college educator may follow us, print out her or his favorite crystallographic structure model in 3D, and use it in hands on class room demonstrations also. On such occasions, one might even like to talk about the UNESCO 2014 International Year of Crystallography [9] in class.
