Embodiment Construction
[0035] specific implementation
[0036] The present invention will be described below in conjunction with the accompanying drawings. Obviously, what the accompanying drawings describe is only a part of the present invention rather than all embodiments.
[0037] Such as figure 1 As shown, the present invention includes: a print head (1), its bottom surface is an electrode array (2), a piston (4) and a powder spreader (5), and the electrode includes a conductive part (7) and an insulating part (8). There is a gap (9) between them. The upper part of the print head is the electrode control circuit (3). The electrode array (2) forms the printed board. The upper part of the print head gradually becomes larger, which effectively reduces the wire density and facilitates manufacturing.
[0038] The printing process starts, the piston moves to the uppermost part of the printing range, and the print head moves away to let the powder spreader spread a layer of powder consumables on th...

A second-generation resistance welding type three-dimensional printer comprises a printing head (1), an electrode array (2) on the bottom face of the printing head (1), a control circuit (3) on the upper portion of the printing head (1), a piston (4) and a powder laying machine (5). The second-generation resistance welding type three-dimensional printer is mainly characterized in that the electrode density is equal to or less than the density of one layer of voxels; except powder laying operation, the printing head does not horizontally move, or the horizontal movement range is very small; a powder cake is pressed in advance, and during printing, the powder cake is used for replacing the powder laying operation; pressure between the printing head and the piston is reduced, the density of aprinted object is lowered, pressure between the printing head and the piston is increased, and the precision / density of the printed object is increased; printing is assisted in a soldering manner; conductive powder is added in, and a non-conductive material is printed; and insulator powder is added in, and a material good in conductive performance is printed. The second-generation resistance welding type three-dimensional printer has the beneficial effects that the printing speed is extremely high, the mechanical structure is further simplified, powder pollution can be effectively reduced, the density of the printed object is controlled, energy conservation and environmental protection are achieved when refractory metal is printed, and non-metal and other materials are printed.
Description
technical field [0001] The present invention is mainly used in the field of three-dimensional printing. Background technique [0002] SLS (Selective laser sintering) selective laser sintering technology: SLS selective laser sintering technology is to lay a layer of powder material (metal powder or non-metal powder) on the worktable in advance, and then let the laser under the control of the computer according to the interface contour information. Part of the powder is sintered, and then circulated continuously to form layers. This solution works well and is a relatively mature metal 3D printing method; however, the laser is expensive and has a short lifespan, which has a certain negative effect on the popularity of this solution. [0003] MIM+FDM, Metal Injection Molding (Metal Injection Molding) combined process Fused Deposition Modeling (Fused Deposition Modeling): This method preforms metal materials and binders into filaments (Filament), which are directly printed into ...
