A specific structure of the lateral 3D printer 10 according to an embodiment of the present invention is described below with reference to fig. 1 to 4.

The lateral 3D printer 10 according to the embodiment of the present invention includes a printing head 100, a primer 200, and a driving system 300.

The primer 200 is moved in units of a set length equal to the thickness of a single printed sheet by the print head 100.

It should be noted that, since the print head 100 can move along the Y-axis and the Z-axis, respectively, the guide 200 receiving the print sheet of the print head 100 can move along the X-axis. Therefore, the embodiment of the present invention provides a 3D printer utilizes the FDM fused deposition modeling technique to the primer 200 as a support, the printing head 100 prints on the Y-Z plane, and after printing one layer, the primer 200 is moved by the unit of the length set by the driving system 300 towards the direction far away from the printing head 100. Since the set length is equal to the thickness of a single printed sheet by the print head 100, the plane just printed advances by the thickness of one sheet away from the print head 100. So as to leave a printing space for the next plane, and the next plane is circularly reciprocated by taking the printing space as a period until the printing is finished. As can be seen from the description, the X-axis direction of the lateral 3D printer 10 according to the embodiment of the present invention is not constrained, and therefore theoretically, infinite length can be printed.

To the problem that the work piece that traditional printer printed out received the restriction of printing bottom plate size, the utility model discloses a 200 parts of primer of horizontal 3D printer 10 are equivalent to the printing bottom plate of vertical printer, but the difference lies in, and the printing bottom plate of vertical printer is the fixed size just after the printer equipment dispatches from the factory, can not change. The primers 200 of the lateral 3D printer 10 of the present embodiment can be replaced with any corresponding size according to the size of the cross section of the workpiece, and the corresponding task can be completed only by correspondingly adjusting the origin of the computer control program. Meanwhile, each layer of cross section printed by the vertical printer is located in a frame formed by the nozzle and the body, and the primer 200 of the horizontal 3D printer 10 of the present embodiment is located outside the frame formed by the printing head 100 and the platform carrying the printing head 100, so that the length and width of the workpiece which can be printed by the horizontal 3D printer 10 of the present embodiment are not limited by the structure of the printing bottom plate and the printer frame of the vertical printer.

It should be noted that, in the embodiment of the present invention, the X-axis, the Y-axis, and the Z-axis directions may be arbitrarily specified, that is, the X-axis direction may be a length direction of the workpiece, a width direction of the workpiece, and a height direction of the workpiece, where the X-axis, the Y-axis, and the Z-axis directions are only used to distinguish the moving directions of the printing head 100 and the lead 200, and are not limited to the moving directions of the printing head 100 and the lead 200. Of course, the X-axis, the Y-axis and the Z-axis may be perpendicular to each other or may be inclined to each other.

According to the utility model discloses horizontal 3D printer 10 because beat printer head 100 and can follow Y axle and Z axle and move respectively, and accept and beat printer head 100 and print the primer 200 of lamella and can follow X axle direction motion, consequently one in length, width, the high size of work piece that horizontal 3D printer 10 can print does not receive print frame's influence, the work piece of printing is more diversified.

It should be additionally noted that, in the embodiment of the present invention, when the printed workpiece extends continuously along the horizontal direction, the size of the vertical direction of the workpiece does not change, the frame of the horizontal 3D printer 10 does not need to be adjusted in any size, and only a proper support structure for offsetting the gravity action needs to be provided to the workpiece along the horizontal direction, so that the overall height of the center of gravity does not change, and the stability during printing is independent of the length of the printed workpiece, so that the height of the center of gravity does not change substantially when printing a special-shaped workpiece, such as a 10-meter long truss, and when printing a 10-centimeter-long workpiece. When the height of the center of gravity is not changed, because the two side surfaces of the workpiece are always in contact with the supporting structure surface of the transverse 3D printer 10, and the part of the newly-printed workpiece extending out simultaneously is also supported by a new lower supporting structure, the printing stability of the transverse 3D printer 10 is greatly improved.

It can be understood that the lead screw has a self-locking function, and the phenomenon that the Z-axis sliding block 313 slides down under the action of gravity to cause damage when the Z-axis sliding block is not used for printing is avoided. It should be noted that the movement structure of the print head 100 may be other ways, for example, a linear motor drives the Z-axis slider 313 to slide relative to the Z-axis support beam 311, and for example, the Z-axis support beam 311 is provided with a transmission chain on which the print head 100 is provided.

In some embodiments, as shown in fig. 1, the drive system 300 includes a Y-axis support beam 321 and a Y-axis slider 323, the Y-axis slider 323 is slidably disposed on the Y-axis support beam 321, and the Z-axis support beam 311 is mounted on the Y-axis slider 323. Therefore, the Z-axis support beam 311 can slide relatively smoothly relative to the Y-axis support beam 321, so that the movement of the print head 100 along the Y-axis is also relatively smooth, and the printing precision of the print head 100 is improved to a certain extent.

Specifically, the driving system 300 further includes a Y-axis lead screw 322 and a Y-axis driving motor 324, the Y-axis lead screw 322 is connected to the Y-axis support beam 321, the Y-axis lead screw 322 is connected to the Y-axis slider 323, and the Y-axis driving motor 324 drives the Y-axis lead screw 322 to rotate so that the Y-axis slider 323 slides relative to the Y-axis support beam 321. Therefore, the Z-axis support beam 311 can slide relatively smoothly relative to the Y-axis support beam 321, so that the movement of the print head 100 along the Y-axis is also relatively smooth, and the printing precision of the print head 100 is improved to a certain extent. It should be noted that the movement structure for driving the Z-axis support beam 311 may be other forms, for example, a linear motor drives the Z-axis support beam 311 to slide relative to the Y-axis support beam 321, for example, a transmission chain is provided on the Y-axis support beam 321, and the Z-axis support beam 311 is provided on the transmission chain.

In some embodiments, as shown in fig. 1, the driving system 300 further includes a push rod device 340 and an X-axis driving motor 331, the push rod device 340 is used for pushing the primers 200 to move towards the side away from the print head 100, and the X-axis driving motor 331 is used for driving the push rod device 340 to move. Thus, the primer 200 can be moved more smoothly in a direction away from the print head 100 when moved.

Therefore, the guide 200 can be further ensured to move smoothly. Advantageously, the side of the push plate 341 with the largest area is used to push the primer 200 to move. Therefore, the contact area of the push plate 341 and the primer 200 can be increased, the pressure between the push plate 341 and the primer 200 is reduced, and the probability that the push plate 341 crushes the newly printed layer sheet of the printing head 100 is reduced.
