Description

Roll type 3D printer {3D PRINTER OF ROLL TYPE}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a roll type 3D printer, and more particularly, to a roll type 3D printer capable of forming an object shape by laminating a rolled material.

Typically, printers are 2D printers that can print flat features, such as letters, pictures, and photographs. 3D printers are more likely to print than 2D printers. That is, the 3D printer is a printer configured to print stereoscopic shapes. These 3D printers use an XY Cartesian coordinate system like a 2D printer, and a Z-axis configuration can be added to print a three-dimensional shape.

3D printers are used in a variety of materials depending on the purpose of printing. As a printing material for a 3D printer, various materials such as plastic, metal, and living cells can be used. 3D printers, which are mainly commercialized and sold, use plastics and metals, while others are used in special purpose 3D printers, which are made by themselves for special purposes.

These 3D printers have recently expired their original patents and can be used by anyone for basic configurations. The basic configuration of a 3D printer includes a base unit for supporting an object so that an object can be printed, a nozzle unit for printing an object three-dimensionally on the base, a nozzle unit connected to the nozzle unit for moving the nozzle unit three- And a feeder unit for supplying printing material to the nozzle unit.

A cover housing for protecting the printing space may be disposed on the base unit of the 3D printer. A heater unit capable of melting the wire material supplied from the feeder unit may be disposed on the nozzle unit side. The wire material is arranged, for example, in a reel-like manner, and is provided as a wire to the nozzle unit side.

A wire material of various colors may be wound on each reel in order to express various colors in the feeder unit. The metal is mainly provided in powder form and forms a three-dimensional shape by laser sintering.

Such conventional 3D printers mainly perform printing by a nozzle unit. At this time, the manner in which the printing material is supplied onto the base unit by the nozzle unit is mainly supplied in a thin line shape. Therefore, when printing an object having a large area, a conventional 3D printer can increase the printing speed by increasing the aperture of the nozzle unit.

In addition, since the conventional 3D printer melts the printer material and mainly performs printing, the compression pressure of the melted material may fluctuate, which may deteriorate the printer quality. If the nozzle unit is clogged, it is difficult to perform printing itself.

As described above, since the conventional 3D printer has to use the nozzle unit essentially, it is not easy to increase the printer speed and the printing quality is influenced by the technical limit of the nozzle unit.

This drive roller 132 may be driven by a built-in motor, not shown, as a roll drive, which causes the printing material to move as needed to the cut shape. The tension roller 135 may be disposed at least one between the feeding roller 131 and the driving roller 132 so that the printing material is in contact with and tensioned. The tension roller 135 applies tension to the sheet-shaped printing material so that the printing material is cut into a precise shape and size when the printing material is cut by the cutting unit 140. The tension rollers 135 may be disposed on both sides of the base unit 170, respectively.

The base unit 170 includes a turntable 171 which is located adjacent to one point of the path of the printing material and can rotate up and down with respect to the Z axis perpendicular to the XY plane coinciding with one surface of the printing material, Lt; / RTI > The turntable 171 may be connected to a table driving unit 175 capable of performing at least one of rotation of the turntable 171 about the Z-axis and up-down movement along the Z-axis. At this time, the turntable 171 may be provided with a coating on the upper surface portion so that the printing material to be cut is easily separated after being stacked in a user input shape. Further, the turntable 171 may be made of a material that can be prevented from being damaged by the cutting unit.

On the other hand, the cutting unit 140 may include a cutter 141 that contacts a surface of the printing material to perform a cutting operation, and a cutter moving unit 145 that moves the cutter 141 on the XY plane. The cutter 141 is capable of physically and chemically cutting the printing material, and may be configured in various manners as described below.

Hereinafter, the description of the elements overlapping with the above will be replaced with the description above, and a detailed description thereof will be omitted.

The cutter 141 shown in FIG. 4 may include a laser module 151 for cutting by laser, an ultrasonic module 152 for cutting by ultrasonic waves, and a blade 153. At this time, the laser module 151 has an intensity that can be cut by a laser, and the laser module 151 may have the same intensity as the laser part used in the metal panel laser cutting, but may have the same structure. In addition, the ultrasonic module 152 may have the same intensity as the ultrasonic wave portion used for ultrasonic cutting of glass, but may have the same structure. Lasers can be used mainly for metal and plastic sheets, and ultrasonic waves can be used for materials with high hardness such as glass. The blade 153 may also be typically used for a plastic sheet. The plastic sheet can also be cut by the laser module 151.

The cutter 141 may be a turret type laser module 151, an ultrasonic module 152 for cutting by ultrasonic waves, and a blade 153. This allows the cutting tool change to be effected while being rotated. The cutter 141 can also be moved on the printing material sheet by the manipulator 160 to perform the cutting operation. Although the manipulator 160 is conceptually shown, it can move the cutter 141 precisely on the printing sheet with the multi-axis robotic arm. It is noted that the manipulator 160 is shown to move the cutter 141, but not limited thereto, and that the cutter 141 can be moved by the XYZ stage configuration described above.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Deletion, addition or the like of the present invention may be variously modified and changed within the scope of the present invention.
