Three-dimensional printing apparatus and the print data storage method

The present invention provides a printing apparatus and a printing stereoisomers data storage method, three-dimensional printing apparatus comprising a processing unit and a mixing unit. The profile processing unit shear layer signal formatted as a print file written. Wherein the shear layer and the print tip speed profile signal corresponding to the three-dimensional structure, the shear layer comprises a plurality of layers of data files corresponding to a plurality of layers of the three-dimensional structure, and a print tip speed signal corresponding to the plurality of layers comprises a layer of three-dimensional structure of the printing data. Mixing unit a partial section and a print tip signal profile storage ratio of combined shear layer profile of layer data in a layer of print data for the mixing speed, and the stored mixing profile in the storage unit three-dimensional printing apparatus, wherein the layer of mixed profile of data corresponding to the print data layer and the layer of the mixed layer of three-dimensional structure of the files corresponding to different three-dimensional structures. Three-dimensional printing apparatus and the print data storing method of the present invention provides, can strike a balance between cost and data storage time printing is repeated.
