The 32 Crystallographic Point Groups

prusaprinters

<p>Models of all 32 Crystal Classes (= crystallographic point groups) for teaching or practice, with spoiler-free, randomized file names. Print as pre-oriented. I used known faces of typical minerals (e.g. diamond and calcite) or small molecule compounds (e.g. tartaric acid and AgI) where possible. For a few groups I could not find documented examples and had to freestyle.</p> <p>There are 33 files, because one example exists in D- and L-configuration (I didn't bother to do that for all chiral symmetries - you can just mirror the models). The pdf is just a printable A4 game board to help with sorting.</p> <p>Add color changes for extra fun - but beware that it becomes nearly impossible for students to figure out ;-)</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>BIQU B1</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>No</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2mm</p></div><strong>Infill:</strong></p> <p>15%</p> <p><strong>Filament:</strong> 3DJake PLA glitter purple</p> </p></p> Category: Learning
