After Friday night’s successful printing of the P. bosei crania, we decided to go for round two of tech fun with our buddy, KNMER 406 – looking for another 3D print and a cardboard cranium.
The printing specs stayed the same (quarter size, MakerBot Replicator 1, ABS plastic, etc.) with the resolution upped to "fine" (0.1 mm layer height vs. 0.3 mm.) And with the recent Domínguez-Rodrigo et al's paper in PLOS One, printing a bosei seemed particularly apropos.
With the MakerBot cheerfully whirring away in the background, I had a chance to laser cut and assemble the full-size 406 cranium from cardboard. The downloadable pdf from African Fossils wasn’t sized for the Trotec laser cutter – however, with Autodesk 123D Make it was fairly straightforward to resize the print sheets to fit the trays. This pdf is the same full-size crania, recut to sheets that fit the TechShop’s equipment. The cardboard sheets are quartered from Office Max science fair boards (ironic, yes), and the “pin holes” are set to the size of bamboo skewers.
Great blending of art, science, and technology and major kudos, again, to African Fossils for their efforts to publish downloadable 3D models.
