(1) three dimensional model structure due to RP system only accept computer structure of products three dimensional model (stereo figure), then to for slice processing, thus first should in PC machine or workstation Shang with CAD software (as UG, and Pro/E, and I-DEAS,), according to products requirements design three dimensional model; or will has has products of II dimension three views conversion into three dimensional model; or in reverse engineering in the, with measurement instrument on has some products entity for scan, get data points cloud, for three dimensional heavy frame.

(2) three dimensional model approximation because the products often have irregular surface, prior to processing must be approximated. Model obtained through approximation is called the STL format file, which consists of a series of connected space of triangles. Typical CAD software conversions and outputs the STL format file interface, but sometimes the triangle will have a small amount of error output, local modification is needed.

(3) the model layer (Slicing) due to the RP process is processed on a layered profile, so necessary for processing into the height of three dimensional models along a series of ordered two-dimensional layers, one that every certain amount of layers to extract section outline. Interval size is selected according to the accuracy and productivity. Smaller the interval, the higher the precision, but longer. Interval in the range of 0.05~0.5 mm and 0.1 mm, can be rather smooth surface. Slice interval when selected, forming material thickness of each layer should be adapted. Forming system with Slicing software can automatically extract the model profile.
