Description

3D printer output device and desorption method using the same {3D printer output device and desorption method}

The present invention relates to a 3D printer output detachment device, and more particularly, to form a groove in the workbench, 3D printer output detachment device for combining the worktable and the detachment means to facilitate separation of the output and the workbench and It relates to a desorption method using the same.

3D printing technology, which is the basis of the present invention, is a technique for making a three-dimensional model using a curable material including plastic. Originally, 3D printers were used by a US company to make prototypes before they were commercialized, but now they are used in various fields of society. In addition, since it is easy to purchase and the usage is well known, it can be easily used in real life and at home.

Representative types of 3D printers include FDM (Fused Deposition Modeling), SLS (Selective Laser Sintering), SLA (Stereo Lithography Apparatus), and DLP (Digital Light Processing). FDM-type 3D printer melts the filament at high temperature to squeeze and stack the filament through the nozzle hole to create a shape. The structure and program are simple, and the cost and maintenance cost of the equipment are low. It has the disadvantages of poor finish quality, weak strength in the stacking direction, and slow manufacturing speed. The SLS method selectively heats the material in a powder form to harden only a specific part, and moves the pedestal in the powder so that the output is stacked. The support structure is unnecessary because the powder is used as a material. However, the disadvantage is that it takes a relatively long time and the equipment is expensive. SLA-type 3D printer uses photocurable liquid resin to move the pedestal in the liquid resin and stacks the layer of cured resin further, which has the advantage of efficient lamination speed and high precision, but adds supporter generation time. The disadvantages are high cost, high cost of materials, equipment and maintenance. DLP method is to cure the resin by curing the resin with UV light source in the tank containing the resin, and it has the advantage of relatively high molding speed and high precision because it is face-to-face molding, but it is limited in size and the resin can be manufactured. This is expensive.

The DLP type 3D printer used in the present invention generally irradiates light upward from the bottom of the tank containing the resin, and thus is attached to the bottom surface of the stage (hereinafter referred to as a work bench) disposed on the top of the tank. The output is produced. After the above process, the printout is attached to the workbench, so the printout should be separated from the workbench.

1 is a view showing a conventional 3D printer output detachment device. Referring to FIG. 1, a stage (hereinafter, referred to as a work bench 100) is generally formed in a plate shape, and has a configuration in which an output is output thereon. In the related art, a user separates an output using a separation tool 10 made of a sharp object such as a knife to separate the output from the work table 100. Or, the user manually separated without using the separation tool (10). When the output is separated in the above manner, the output may be damaged, thereby degrading the completeness of the output. In addition, the workbench 100 may likewise be damaged and may not be reused.
