3D PRINTER FOR CHMBER

More particularly, the present invention relates to a chamber for a 3D printer, and more particularly to a 3D printer capable of stably protecting a 3D printer while preventing noise and vibration generated in a 3D printer during a 3D printer operation, And to remove harmful odors generated during the operation.

Generally, a 3D printer is a device that produces a three-dimensional solid object. The 3D printer is divided into a cutting-type 3D printer and a stacking-type 3D printer. The cutting-type 3D printer is a printer that cuts a large chunk into three- Is a printer that stacks materials to produce three-dimensional objects.

The cutting-type 3D printer produces a three-dimensional solid body by cutting a large lump, so that material loss occurs. However, the stacked-type 3D printer does not lose material because the material is stacked on the bed to form a three-dimensional solid body.

Because of these advantages, most of the recent 3D printers use stacked 3D printers. Types of stacked 3D printers include 3D printers using FDM (Fused Deposition Modeling) using solid materials, SLAs using liquid materials (StereoLithography Appartus) type 3D printers, and SLS (Selective Laser Sintering) type 3D printers using powder type materials.

Among the stacked 3D printers, the FDM type 3D printer is a printer that produces a three-dimensional solid body by melting a thin plastic thread such as ABS, PLA, urethane, and epoxy called a filament and stacking it on a bed.

Such prior art techniques pull filaments made of PLA (Polylactic Acid Poly Lactic Acid) plastic or ABS (Acrylonitrile Butadiene Styrene) plastic through the gap between the serrated rollers and idler rollers, When the speed and the retraction speed are increased, the filaments are worn out by the rollers (the filaments are broken due to the pushing and pulling only by the force in one direction), there is a gap between the rollers of the toothed rollers and the bearings, The amount became unstable and the output quality was affected.

In addition, these prior arts have a problem that noise, vibration, and harmful odor generated in the 3D printer are directly transmitted to the room during the molding operation of the product as a 3D printer.
