About this model

Aspirin (C9H8O4, CAS 50-78-2) — a free educational 3D molecular model for teachers and students, by MolGod.org. Every atom carries its engraved element symbol, so no colour key is needed. Ordinary molecular STL files leave students guessing, because the colour scheme that identifies atoms on screen does not survive printing. MolGod adds what the STL format leaves out by engraving the element symbol into each atom of the printed structure. The aim of this scientific education project is to help students identify the atoms of a molecule faster and so grasp its chemistry and 3D geometry sooner. For teachers it also saves preparation: the file is already modelled and labelled, so the only steps left are scaling and slicing. Read why we engrave the atoms, and which studies inspired the project:…
