made from only one angle), you will need to add thickness to the surface in order to convert it to a solid model. While I have intentionally left voids in the sculpture, for artistic effect, I'll show you techniques to close holes and smooth the model if necessary. 3D printing from bad scan data is much more challenging than 3D printing from a 'clean' scan, so I'm going to walk you through the process of repairing a fairly messy scan and preparing it for 3D printing. In my practice as a sculptor, I intentionally misuse high-end 3D scanners to generate glitchy results. While some scanners come bundled with software that will surface the scan and export the file as one continuous surface, others don't, so this tutorial will cover repairing raw, unsurfaced scan data. I'm beginning with a fairly rough scan, made with a handheld 3D laser scanner. We need to address all these issues in order to prepare a model that a 3D printer will accept. They also frequently contain holes, self-intersections, non-manifold geometry, and incorrectly oriented polygons. Unless the object was scanned in 360 degrees, the scan file will appear as a shell with no thickness. Raw 3D scans present a number of challenges for 3D printing.
