Smile Train later used the 3D models of the two Chinese patients to build the first 3D open access virtual surgical simulator, which teaches cleft palate and lip surgery to doctors in developing countries. The simulator, which was created in partnership with BioDigital Systems, is web-based, open source and available for free. It does not require any special hardware to use. A mobile application is under development. In September 2014, Smile Train showcased a 3D virtual surgery simulator at TEDMED 2014 in Washington, D.C.
