Manipulation of the model was performed in Magics RP (Materialise n.v). To prepare the model for stereolithography, the surface model was hollowed to create a 3mm wall thickness shell in order to reduce RP build time and weight of the model. A hole was then created in the base surface to allow resin to drain from the hollow part after construction. The RP model was realised using a SLA 5000 (3D Systems Inc) system in Watershed 11122 XC resin (DSM Somos). A layer thickness of 0.1mm was employed.
From the complete point cloud produced from scanning the entirety of the artifact’s surface, a finite element mesh was constructed. This is a 3D model based from small triangular facets, all scans taken were optimised to ensure that there were no stepped surfaces and the point cloud was filtered to a point spacing of 0.3mm. Boundary points were inserted to ensure surface definition and small holes in the mesh was filled using curvature analysis. This was achieved using Metris Kube software.
