Abstract: The present invention relates to a 3D printer for construction for printing and forming various structures wherein a roller 50 follows a nozzle 10 which discharges concrete, mortar, or the like, to bring an outer peripheral surface of the roller 50 to be in close contact with a surface of the printed object, and thus the surface of the printed object is flattened. According to the present invention, a high-degree surface flattening work can be performed on the surface of a printed object simultaneously as the printed object is printed by a 3D printer for construction, thus enabling rapid and reliable flattening of the printed object and smooth surface forming.

Abstract: The present disclosure relates to a 3D printer for construction for printing and forming various structures, in which agitating blades 45 capable of auto-rotation are mounted inside a nozzle 10 discharging a printing material such as concrete or mortar, to thereby enable agitation of a fluid printing material inside the nozzle 10. According to the present disclosure, agitation of the fluid printing material inside the nozzle 10 of the 3D printer for construction may be facilitated to prevent material segregation and maintain a homogeneously mixed state of materials constituting the fluid printing material.

Abstract: The present disclosure relates to a 3D printer for construction for print-molding various structures, in which a main pipe 30 for transferring a filament material 31 therein is installed inside a nozzle 10 for discharging a printing material, such as concrete or mortar, to enable co-printing of the filament material 31 with the printing material while embedded in the printing material. According to the present disclosure, in constructing a structure by a 3D printer for construction, a printing material embedded with the filament material 31 as reinforcing material may be printed, and as a result, the effects of reinforcing tensile strength of the printed object and inhibiting crack of the printed object may be obtained.

Abstract: The present invention relates to a 3D printer for construction for printing and forming various structures, in which a spray pipe 60 follows a nozzle 10 for discharging concrete or mortar, and sprays a liquid material onto the surface of a printed object, thereby enabling the liquid material to be applied on the surface of the printed object. Through the present invention, the printing of the printed object and the spraying of the liquid material onto the surface of the printed object may be carried out simultaneously by means of the 3D printer for construction, and thus a rapid and uniform coating treatment of the printed object is possible, and an adequate wet state of the tissue of the printed object may be maintained.

Abstract: Disclosed are personality testing device and method.

Abstract: A mobile terminal is provided. The mobile terminal includes a display for sensing at least one of a touch or an approach of a pointing means and a controller for controlling brightness of a sensed area according to the sensed touch or the approach of the pointing means.

Abstract: A method of displaying a first image on a mobile terminal, the method comprising: displaying a first image and a second image overlaid on the first image on a display unit of the mobile terminal; and changing the orientation of the first image and the second image according to a variation in the orientation of the mobile terminal.

Abstract: A mobile terminal and a method of controlling the operation of the mobile terminal are provided. The method includes displaying a first image on a touch screen; and if a multi-touch input is detected from the first image and then a drag input for dragging the first image is detected, displaying the first image as being torn from one side of the touch screen and storing the first image. Therefore, it is possible to easily store an image displayed on the touch screen in response to a multi-touch input and thus to effectively use the image for various purposes.

Abstract: A method of controlling a mobile terminal, and which includes displaying a panorama guide including a lattice having at least two rows on a preview screen when a panorama photographing operation using a camera on the terminal is performed, sensing a motion of the terminal, and displaying a position guide indicating a photographing position of the terminal when performing the panorama photographing operation.

Abstract: Disclosed is an event control method of a mobile terminal, in which when a touch input is detected, a shape and size of a lock screen is changed according to the detected touch input value (e.g., touch time, the number of touch times or touch area) and simultaneously a threshold value necessary for unlocking the lock screen 50 is displayed, and then the lock screen is unlocked and switched to a menu screen when the touch input value reaches the threshold value, resulting in providing a user with more enjoyable and exciting user interface (UI).

Abstract: A method of controlling a mobile terminal is provided. The method includes displaying a first screen image, receiving weather information, providing a semi-transparent filter effect corresponding to the weather information, and overlaying the semi-transparent filter effect onto the first screen image to create a second composite image, and displaying the second composite image. A mobile terminal is also provided, which includes a display module configured to display a first screen image as an idle screen background, a wireless communication unit configured to receive weather information through a communication network, and a controller configured to overlay a semi-transparent filter effect corresponding to the received weather information onto the first screen image to create a second composite image, and then to display the second composite image.
