(21) Rodenbough, Vanti, and Chan have provided an algorithm for 3D-printing of models of all seven crystal systems. For example, Scalfani and Vaid have shared several files of molecular models ready for 3D-printing as well as instructions for how to prepare files of any real and imagined molecules for 3D-printing. (20) At first, the procedure of creating files suitable for 3D-printing of chemical models was not straightforward and required the use of specialized software and skills. (14−19) The very recent systematic review on 3D-printing in chemistry education covers 47 peer-reviewed articles available to date. The emergence of 3D-printing technologies has led many researchers to develop methods for printing molecular models. Worksheets to use in conjunction with the models in classrooms are provided. The preassembled sets of 3D-printed models described here can be implemented in many courses, including general chemistry, organic and inorganic chemistry, solid state chemistry, crystal chemistry, and so on, which cover the audience of university students of all years and levels, as well as high school students. The prepared sets of models are well-suited to teaching molecular structure and symmetry, for showing differences between idealized and real molecules, for explaining crystallographic and noncrystallographic symmetry, and for showing conformational flexibility. Simultaneous employment of all the mentioned resources actuates both visual and haptic perception, and their complementary action enhances the effectiveness of teaching and students’ engagement. The use of such models for teaching in classrooms along with idealized ball-and-stick models and computer software is encouraged. This allows teachers to save time on searching for relevant examples and to acquire tangible models of molecules even in the absence of freely available 3D-printing facilities. You can search either the full COD and then design your own model for 3D printing, or search the more than 30,000 predefined sample files from this figshare collection and download the STL or WRL files that have already been created for those structures.Sets of models of molecules (which are of interest for teaching molecular structure, symmetry, and related topics in many chemical disciplines) were prepared and made available either for self-directed 3D-printing or through the 3D-printing company Shapeways providing 3D-printing as a service. The Jmol 3D print website allows creation of STL and VRML files for 3D printing for any structure in the Crystallography Open Database. FIles are named with corresponding Crystallography Open Database ID.Ī searchable website for this collection is available here: There are 31,239 WRL2 color 3D printable files and 11,732 STL 3D printable files.
