ABSTRACT

Changes in the online availability of 3D models of skeletal elements and 3D printer technology have made it feasible to develop a fossil or osteological collection from scratch. Many online sites have models that can be freely downloaded and 3D printed. Other sites have CT-scan movies online—which can be downloaded and turned into printable 3D models by using the free software suite SPIERS. Post-processing of the printed models (sanding, painting, etc.) can make them almost visually indistinguishable from real specimens.

Keywords: three-dimensional printing; CT-scan; teaching

 

RESUMO [in Portuguese]

Alterações na disponibilidade on-line de modelos 3D de elementos esqueléticos e a tecnologia de impressão 3D tornaram possível desenvolver uma colecção, a partir do zero, de osteologia ou fósseis. Muitos sítios on-line têm modelos que podem ser descarregados gratuitamente e impressos em 3D. Outros sítios disponibilizam filmes de tomografias computorizadas que podem ser descarregados e convertidos em modelos 3D para impressão usando programa informático livre SPIERS. O pós-processamento dos modelos impressos (lixamento, pintura, etc.) pode torná-los quase indistinguíveis dos espécimes reais.
