The technical scheme adopted by the invention is as follows:
a polylactic acid three-dimensional printing method, comprising the steps of:
the method comprises the following steps of adopting a three-dimensional printer, wherein the three-dimensional printer comprises a rack, a rotating device, a turntable, a plurality of supporting plates, a three-axis moving device, a printing head and a controller; the controllers are electrically connected with the rotating device, the three-axis moving device and the printing head; the supporting plates are distributed on the upper end face of the turntable in a circumferential array mode, each supporting plate forms a printing station, the three-axis moving device is fixedly installed on the rack, the printing head is fixedly installed on the three-axis moving device, and the printing head is arranged above one of the supporting plates; the controller controls the printing head to extrude the molten polylactic acid printing consumable material to be solidified on the supporting plate, the controller controls the three-axis moving device to drive the printing head to form a two-dimensional fixed object on the supporting plate, after one layer of the two-dimensional fixed object is finished, the controller controls the three-axis moving device to drive the printing head to move upwards for a preset distance, the controller continuously controls the three-axis moving device to move to drive the printing head to extrude the molten polylactic acid printing consumable material to form a next layer of the two-dimensional fixed object, and a plurality of layers of the two-dimensional fixed objects are stacked to form a three-dimensional fixed object; after the printing of one supporting plate is completed, the controller controls the three-axis moving device to ascend to drive the printing head to ascend, the controller controls the rotating device to rotate, the supporting plate on the next station rotates to the position below the printing head, and the controller controls the three-axis moving device to descend to enable the printing head to be close to the supporting plate to print the next three-dimensional fixed object.
The three-axis moving device comprises a transverse moving device, a longitudinal moving device and a vertical moving device. The printing head is fixedly arranged on the transverse moving device, the transverse moving device is fixedly arranged on the vertical moving device, and the vertical moving device is fixedly arranged on the longitudinal moving device.
The three-axis moving device drives the printing head to move in a moving space; one end of the rotary disc is arranged in the moving space, and the other end of the rotary disc is arranged outside the moving space.
Further, the lower end face of the rotary table is fixedly connected with a heater for heating the rotary table.
The turntable is provided with a plurality of printing stations, two printing stations can be adopted, and four printing stations can also be adopted.
Because the mode that adopts the carousel goes on a plurality of stations through rotatory mode, consequently triaxial mobile device then can not adopt the design of large-span, consequently reduced the error, the mode of carousel can make and need not the artifical backup pad of constantly clearing up change moreover.
The invention has the beneficial effects that: can print out a plurality of products through the triaxial mobile device of small-span, improve work efficiency, the advantage of cost is reduced.
