(1) Slice 3D CAD model conversions for fast data format that the original shape system can accept, such as the document of STL, usage slice the software cut into model the thin slice that a series specify the thickness.
(2) Scan to pass the number to control to equip to control laser or other home works device, at current job class up scan a slice to cut to face the shape, carry on taking shape the work. In take shape process, the most basic operation is to scan solid turn the spare parts to cut the noodles, the layering get of cut and face the information is the outline data, to carry on the internal to fill, must be is born by the outline data to fill the path.
(3) Enter to the work pedestal that the ambulation puts the semi-processed goods along the Z stalk direction descends the certain distance, repeat is suddenly up the one step and this step, until the spare parts takes shape completely.
(4) Handle behind according to the demand of the different and applied situation, distinguish to the spare parts after carry on solidly turn, apply paint, burn the knot, the copper etc. processing.
1. 3 The technique of RPM is in molding tool make of usage
  The prototype of the RPM technique creation under the condition of many because of usage there strict of the material, can't still act for the end and true product. In order to acquire the product of the true material creation, and the fast formation production ability of the certain batch quantity, produced then according to the RPM technical and fast molding tool  RT( the Rapid Tooling) technique .The RT adoption  RP technique is direct or the indirectly manufacture the molding tool, making the manufacturing time and cost of the molding tool shortenned consumedly.
(1) Use to model the direct manufacture molding tool of machine quickly because of some take shape the work piece that mechanism make to compare quickly good of machine strength and stability, so can used to some molding tools directly. Currently, can make the fast prototype craft of the metals molding tool to include SLS,3 D2Ps, SDM and 3 D Welding etc. directly .The most typical craft method is an American company of DTM to produce to note the mold of the RT patent technique.
(2) Use model the machine indirectly  manufacture molding tool quickly because of fast prototype direct manufacturing the molding tool controls the aspect in the molding tool accuracy and function more difficult, the special empress handles the equipments and crafts to make cost exaltation compare greatly, the molding tool size also is subjected to limit greatly more. Compare under, the indirect fast molding tool manufacturing turns over to make the technique to combine together to make the molding tool through fast prototype technique and traditional molding tools regardless in the molding tool accuracy, surface quantity, the machine function and service life, still can get the good control in economic aspects. Therefore, make the mold quickly according to the RP currently much for the indirectly system mold method.
(3) Use to model a manufacture female die quickly, make duplicate the soft molding tool to use to model the piece to make the female die quickly, can sprinkle to note the soft materials, such as wax, rubber of Si and the wreath oxygen resin...etc. to constitute the soft molding tool or sprinkle to note the rubber of Si , the wreath oxygen  resin mold first, then sprinkle to note the wax mold. Among them, the wax mold used for the mold's cast. The Si rubber mold can make to manufacture use to note the mold or low to order the metal alloy foundry mold on a trial basis to.
(4) Use to model the piece to make the female die quickly, make duplicate the hard molding tool to use to model the piece to make the female die quickly or according to soft molding tool that it make duplicate, can sprinkle to note the porcelain and ceramics, the metals to synthesize the material, metals, constitute the hard molding tool, thus the batch quantity born plastics piece or metals piece. This kind of molding tool has the good machine to process the function, can carry on slice of part's pare to process, in order to acquire the higher accuracy, or join the piece, cooling system and sprinkle to note system etc.. 模具快速制造技术英文文献和中文翻译(2):http://www.youerw.com/fanyi/lunwen_30873.html
