3D printing workflow. 3D printing involves segmentation of a 3D imaging dataset by assigning grey pixels to the anatomical area of interest which is then converted to a file format recognised by a 3D printer. (Most commonly Standard Tessellation Language, STL format). The STL file can be either used for printing out a physical replica or incorporated into virtual platforms for computer-aided design and modelling. 3DTOE Three-Dimensional Echocardiography, MDCT Multi Detector Computational Tomography, CMR Cardiac Magnetic Resonance
