Background technology
seal has passed on several thousand as one of the traditional art of Chinese nation representative, traditional seal is many passes through cutting by matrix material, the methods such as engraving process, it belongs to " subtracting the material manufacturing ", its matrix material is mainly traditional stone material, pottery (mud), the resin that the material such as timber and modern age occur, other macromolecular materials etc., tradition is single by subtracting its version of seal that the material manufacture method processes, and employing metal material such as copper, gold, the method of machined or casting is adopted in the making that silver waits material to carry out seal as base material more, although it can enrich the version of seal, but its manufacturing process is loaded down with trivial details, cost of manufacture is high.
Summary of the invention
For the problems referred to above, the 3D that the invention provides a kind of seal prints manufacture method, and it can overcome the single problem of traditional seal version, can solve the problem that the metal material making stamp is loaded down with trivial details, cost is high again.
Its technical scheme is such, it is characterized in that: it adopts and increases the making that the material manufacturing technology is carried out seal, and it mainly comprises the following steps:
(1) carry out the foundation of computer three-dimensional model for the overall structure of seal;
(2) the described computer three-dimensional model of seal is carried out the two dimension processing, be about to described computer three-dimensional model and be divided into a series of X-Y schemes along Z-direction by the bed thickness that equates;
(3) according to the corresponding laser beam scan path of described a series of plan generations;
(4) lay equably the layer of material powder increasing on material manufacturing equipment processing platform;
(5) utilize superlaser or electron beam by the material powder on the described processing platform of described laser beam scan path scanning, be subjected to be consolidated in after the material powder fusing of described superlaser or electron beam scanning described processing platform surface;
(6) in clinkering the processing platform surface of one layer pattern lay second layer material powder;
(7) repeating step (5), (6) successively are until the seal monolithic molding;
(8) will shift out from increase the material manufacturing equipment with the seal that is sintered at processing platform is whole together with processing platform again, clear up seal surface and internal float powder, and adopt the mode of line cutting that seal is separated from processing platform is surperficial.
It is further characterized in that:
Every one deck is layed in the thickness of the material powder on described processing platform and equates with bed thickness in described step (2);
Described bed thickness is 0.01mm～0.1 mm;
The particle diameter of described material powder is in 0-60 μ m left and right;
The described material manufacturing technology that increases comprises that fused deposition technology (FDM), electron beam melting (EBM), laser near-net-shape (LEMS), selective laser sintering (SLS), direct metal powder sintered (DMLS), 3D print any in (3DP) technology;
Described material powder is that acrylic acid-butadiene-styrene (ABS), Merlon, polyester, polyphenyl, titanium alloy, aluminium alloy, nickel-base alloy, stainless steel, tool steel, copper, noble metal and other can be used for increasing any in metal, macromolecule and the ceramic material that material makes.
adopt the inventive method to carry out the making of seal, its beneficial effect is: it adopts the method that increases the material manufacturing to carry out the making of seal, it is to control the scanning pattern of focused high-energy laser beam or electron beam by computer, local melting powder metal materials at high temperature, and successively pile up, thereby directly generate the entity component of fine and close geometry according to the 3 D complex computer model, thereby it can manufacture and design according to customer requirement the seal of different version, overcome and adopted tradition to subtract the single problem of seal structure form that the material manufacture method is made, it has greatly made up the defective of traditional machined and casting technique simultaneously, improved the make efficiency of seal, reduced cost of manufacture.
