The iSense scanner Media:http://www.3dsystems.com/shop/isense is available to create .obj files from sequential photos taken with an iPad camera. It doesn't have engineering-quality resolution, but it's OK for generating a 3-d file of a head or medium-sized object. Scanning takes 3-4 minutes. Meshmixer can be used to edit the .obj file generated by the iSense software, and Cura can read the file directly for printing.
See Dr. Walker to use the iSense. A higher resolution scanner Media:http://www.creaform3d.com/en/metrology-solutions/portable-3d-scanner-handyscan-3d will be available in the permanent Maker Space.
