Abstract: A three-dimensional (3D) printer including a floating solution for reducing resin usage may include a main frame, a water tank disposed inside the main frame, a build platform slidable in a vertical direction along the water tank, an optical assembly disposed at an upper portion of the main frame and irradiating a laser beam to the build platform, resin contained inside the water tank, and the floating solution contained inside the water tank, wherein the floating solution is not mixed with the resin, has a higher density than the resin, and supports the resin.

Abstract: A device for producing a skin care pack using a hydrogel and to a control method thereof are disclosed. The device includes: a housing which is provided with a door for selectively opening and closing a work space for forming a skin care pack, and maintains a forming temperature required for producing the skin care pack; a platform having a base supported on a floor plate of the work space of the housing; a former including one or more nozzle modules which are provided to be movable in the work space and heat and discharge a hydrogel onto the platform; and a control unit for controlling the movement of the nozzle modules and the discharge of the hydrogel from the nozzle modules.

Abstract: One aspect of the present disclosure relates to an apparatus for manufacturing a skin care pack. According to an aspect of the present invention, the apparatus for manufacturing a skin care pack may be provided, the apparatus containing: a housing for providing a working space for forming a skin care pack; a film moving module provided to be movable in one direction within the working space, and having a base on which a film is mounted; a molding machine provided to be movable within the working space in two directions perpendicular to the one direction, and including at least one nozzle module for discharging hydrogel to the base; and a controller for controlling movement of the film moving module and the nozzle module, and controlling discharge of the hydrogel from the molding machine.
