(4) printer carries out scraper paving powder according to every layer thickness, and laser head carries out selective sintering according to the X-Y scheme of every layer, model, repeats to spread powder, sintering, until printed;
(5) printout taken out and carry out annealing destressing process, shot blasting on surface process, mechanical artificial aging.
Further, for the Light deformation produced when reducing printing and destressing process, improve the elastomer accuracy of form and position, according to the concrete contour structures of elastomer, draw out the three-dimensional support frame model mated with threedimensional model, itself and elastomer threedimensional model are split simultaneously and are inputted 3D printer, after printout completes, annealed destressing process, removes supporting frame part, then carries out bead and artificial aging.
Described 3D printer is commercially available conventional products, such as EOSINT M280 3D printer.
Described drafting elastomer threedimensional model, generally adopts the three-dimensional softwares such as SolidWorks, ProE, UG, Catia.
Describedly carry out stress analysis to model, the general softwares such as Ansys that adopt carry out stress analysis and Virtual Calibration in conjunction with data processing softwares such as MATLAB, to verify that can elastomer threedimensional model meet the designing requirements such as precision, the linearity, sensitivity, multiplicity.
The described X-Y scheme of uniform thickness that is divided into by threedimensional model generally takes the three-dimensional software supporting with 3D printer, such as ProE, UG etc.
The material that described paving powder can adopt the multi-dimension force sensor elastomers such as titanium alloy, aluminium alloy, structural alloy steel, stainless steel to make.
