Coming from a medical device manufacturing background, the initial 3D business used CT or MRI scans to reproduce exact copies of patients bones, think of it as a 3D X-ray. Surgeons would use these bones to practice a procedure before the real operation.
The 3D printer we used printed in plaster of Paris and it was the only true full colour 3D printer on the market at that time. We invested in a 3D scanner and made miniature models of people.
Our son was crazy about LEGO and we would find minifigures everywhere around the house. We set out to see if it was possible to make a 3D model using just a photograph and make a miniature version of his head that would fit on a minifigure body. When it launched it went viral around the world, selling in 58 different countries. www.funky3dfaces.com
With our experience in 3D, we were amazed at the technology that was available to create interactive, 3D virtual tours. We were selling our house at the time and having difficulty attracting potential buyers. We purchased the 3D scanner and used our own house as a test and we had an offer made within two weeks of it going live.
