Specifically, by connecting the first end of the metal strip 2 with the first feeding shaft 41, and connecting the second end of the metal strip 2 with the first receiving shaft 42, the continuous conveying of the metal strip 2 can be realized, that is, the metal strip 2 is conveyed onto the processing platform 1 and the position matched with the region 11 to be cut is cut, and the cut metal strip 2 is stored, so that the continuity of 3D printing of the metal sheet is realized.
The terms "left side" and "right side" are used to describe the orientations shown in fig. 1, and in actual operation, the terms "left side" and "right side" may be referred to as "front side" and "rear side", for example, depending on the actual orientations.

In one embodiment, the 3D printing apparatus further comprises a speed monitoring sensor (not shown) capable of monitoring the running speeds of the metallic tape 2 and the nonmetallic tape 3, respectively.

It is easy to understand that the rotation speed is a vector, and the rotation speed is the same, namely the rotation speed is the same, and the rotation direction of the rotation speed is the same. In addition, only if the rotation speed of the first feeding shaft 41 is ensured to be the same as that of the first receiving shaft 42, the rotation speed of the second feeding shaft 51 is ensured to be the same as that of the second receiving shaft 52, so that smooth running of the metal material strip 2 and the nonmetal material strip 3 can be promoted, and stacking or winding of the metal material strip 2 and the nonmetal material strip 3 can be avoided.
As shown in fig. 1, the hot roll coating mechanism 8 is also schematically shown to include glue applicators (not shown) capable of applying adhesive to the upper surface of the sheet metal stock and the upper surface of the non-sheet metal stock, respectively.

In this way, when the upper surface of the metal sheet or the nonmetal sheet is sprayed with the adhesive, in order to ensure that the adhesive can be firmly adhered to the surface of the metal sheet or the nonmetal sheet, the upper surface of the metal sheet or the nonmetal sheet is rolled by the hot-pressing shaft 81, so that the adhesive can be firmly fixed on the upper surface of the metal sheet or the nonmetal sheet, and further, the metal sheet or the nonmetal sheet of the adjacent layers can be firmly connected.
In a preferred embodiment of the application, as shown in fig. 1, the translational stage 7 is moved by a crane in the longitudinal direction in a direction towards and away from the processing platform 1. Specifically, when the metal strip needs to be printed, the lifting frame carries the translational lifting stage 7 to move from the lower part of the non-metal strip 3 to the lower part of the metal strip 2 along the width direction of the processing platform 1 until the metal strip 2 moves to the right lower part and then stops moving, at this time, the cutter 6 is started to cut the metal strip 2 and the boundary matched with the to-be-cut area 11, and the cut metal sheet falls onto the translational lifting stage 7 under the action of gravity, so that the carrying of the metal sheet is completed. Similarly, when the nonmetallic material strip 3 needs to be printed, the lifting frame needs to be made to carry the translational lifting stage 7 to move from the lower part of the metallic material strip 2 to the lower part of the nonmetallic material strip 3 along the width direction of the processing platform 1 until the nonmetallic material strip 3 moves to the right lower part and then stops moving, at this time, the cutter 6 is started to cut the nonmetallic material strip 3 and the boundary matched with the to-be-cut area 11, and at this time, the cut nonmetallic sheet falls onto the translational lifting stage 7 under the action of gravity, so that the nonmetallic sheet is carried.

In a specific embodiment, the cutter 6 is preferably a laser cutter. It should be noted that the cutter 6 is not limited to the above embodiments, and may be adjusted according to actual needs, for example, a nicking cutter.
In summary, the computer processes the CAD model of the electronic circuit functional device to be printed into layer-by-layer information, and generates the instruction code identifiable by the printing device and sends the instruction code to the printer according to the layer-by-layer geometrical information obtained after the layering process, through the identification of the inner and outer contour shapes of the layer and the characteristic judgment of the region 11 to be cut. The metal material belt 2 and the nonmetal material belt 3 can respectively convey the metal material belt 2 or the nonmetal material belt 3 to the area 11 to be cut of the processing platform 1 through the linkage control of the first driving mechanism 4 or the second driving mechanism 5 according to corresponding instruction codes so as to wait for being cut by the cutter 6 to form corresponding outlines. At the same time, the hot rolling spraying mechanism 8 sprays different adhesives on the upper layer of sheet materials according to the material strips of different materials, the nonmetallic material strips 3 are sprayed with nonmetallic special adhesives, the metallic material strips 2 are sprayed with metallic active adhesives, and then the cut sheet materials are adhered and formed with the upper layer of sheet materials by the hot rolling spraying mechanism 8. In this way, the metal tape 2 and the nonmetal tape 3 are repeatedly cut and bonded layer by layer, and after printing is completed, a complete electronic circuit functional device can be printed through post-processing. That is, by using the layer-by-layer superposition printing of the metal material belt 2 and the nonmetal material belt 3, the electronic circuit functional device can be printed into a solid part, namely, the printed electronic circuit functional device has certain insulativity while having the conductive function.
In addition, through adopting low cost's metal material area 2 to carry out the stack and print layer upon layer with nonmetallic material area 3 to can make the electronic circuit function device who prints through 3D have certain pliability and insulating nature again simultaneously concurrently, the electronic circuit function device who prints through 3D still can install on 3D electronic device, intelligent machine or radio frequency communication, from this, just improved the using value of electronic circuit function device greatly.
