Objective： Develop a software system which is compatible to medical image processing software,providing faster and more convenient medical 3D Printing. Methods： Based on existing 3D printing systems,propose a series of optimizations for slicing algorithm,minimal support algorithm and multi-extruder function. The software is implemented on the platform of VTK and Qt. Result： A medical 3D printing software MDPrinter was developed. Conclusion： With MDPrinter,the slicing speed,the software stability and surface quality after optimization of supporting structures are all increased. Besides,multi-extruder function suits well for multi-model and multi-material 3D printing. All of these can be a great to the informatization of digital medical.
