Embodiment Construction
[0027] Combine below Figure 1 to Figure 2 The present invention will be further described.
[0028] A five-axis linkage 3D printer, comprising a nozzle 6, a nozzle driving unit, a substrate driving unit, a base 4, an electronic control system; a scanning unit, and a computer;
[0029] The substrate driving unit includes a trapezoidal swing arm 5, a first drive motor 9, and a second drive motor 10; the swing arm is trapezoidal, and the swing arm is elongated. This structure has stability and high rigidity, resulting in high processing accuracy. In order to keep the overall structural height of the machine tool within an appropriate range, a groove 8 is provided on the base 4 . In order to arrange the substrate driving unit in the groove 8 , the base 4 is provided with a fixed bracket 12 and a support seat 14 . The fixed bracket 12 is provided with a first bearing seat 13, and the first bearing seat 13 is rotatably connected with one end of the trapezoidal swing arm 5,...

The invention discloses a five-axis linkage 3D printer, and relates to the field of 3D printers. A base material driving unit is used for driving and controlling a base material to rotate on a base; a nozzle driving unit is used for controlling the position of a nozzle of the D printer in the horizontal direction and the vertical direction. a scanning unit is used for scanning the motion trail of the shooting base material and transmitting the motion trail information to the electric control system; an electric control system is used for collecting information of the scanning unit and controlling the nozzle driving unit and the base material driving unit to move. The position of the spray head is accurately controlled in the x-axis direction, the y-axis direction and the z-axis direction, the rotary table is placed in the groove of the base, the trapezoidal swing arm is used, the rotation center is lower than the rotation center of the swing arm, the height of the rotary table is reduced, and therefore the overall height of the driving device is reduced, and cost is reduced.
Description
technical field [0001] The invention relates to the field of 3D printers, in particular to a five-axis linkage 3D printer. Background technique [0002] 3D printing technology, a kind of rapid prototyping technology, also known as additive manufacturing, is a method based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. Technology. Existing 3D printers are generally three-axis printers, which are based on cumulative printing on a plane. The printing workpiece needs to be accurately positioned, and the printing time is long, and it is difficult to print the workpiece to print production equipment. Contents of the invention [0003] In order to add two new dimensions on the basis of traditional 3D printing, realize 360-degree rotation on the horizontal plane and positive and negative 90-degree rotation in the printing process, improve printing efficiency at the same time, realize multi-dime...
