Summary: | Stereolithographic SL biomodelling is a relatively new technology that allows threedimensional 3D computed tomography CT data to be used to generate accurate solid plastic replicas of biological structures biomodels. A prospective trial to investigate the utility of biomodelling in palaeontology was performed. Seven fossil specimens were selected. Volumetric 3D reconstructions were generated on each specimen. The data of interest were edited and converted into a form acceptable for SL. SL uses a laser to selectively polymerize photosensitive resin to manufacture each biomodel. The biomodels were assessed for fidelity, internal morphology and for use in display and demonstration. Biomodelling was found to faithfully replicate the fossilized specimens. The most important variable affecting biomodel accuracy was the initial acquisition of 3D CT data. Biomodelling is intuitive, userfriendly technology that facilitates morphological assessment and specimen reconstruction. Biomodelling allowed both internal and external features of fragile specimens to be safely replicated without risk. |
