HOLLY SCAN & VIDEO
In Summer 2013 we scanned Holly in 3D and filmed the process of the scanning itself and how her 20cm figurine was printed out on a 3DSystems ceramic printer.
The resulting video is less than two minutes long but shows how the handheld Artec Eva 3D scanner can pick up incredible detail in texture and colour, what the mesh file looks like, what a solid rendered file looks like and finally, how the finished data file is sent to the printer to produce a 3D figurine. The Artec Eva is based on video technology and can scan at up to 16fps.
The figurine of Holly took around eight hours to print out. The printer lays down 0.1mm of ceramic powder each pass and each layer is bonded to the next, slowly building up the finished model. On each layer, it also adds approximately 1mm of colour around the edge, so the figurine is entirely coloured within the machine. The colour is being read from the data file. As the bed of the printer sinks lower to accommodate the growing figurine, the loose ceramic which has not been bonded forms in a powder mass around the figurine. The figurine is then extracted from the loose powder and brushed off at the end of the process. All the loose ceramic powder is vacuumed out and recycled back into the machine for the next job.
Our sister company, www.europac3d.com, sells Artec 3D scanners and a comprehensive range of other industrial scanners for professional use. Europac3D are also resellers for the class-leading 3DSystems series of ceramic, plastic and wax printers and downloadable information can be found on the Europac website.
