1. A curing device for a 3D printer product comprising, a chamber having an accommodation space for accommodating 3D printer products (hereinafter referred to as 3D printer product), and configured to perform a curing process on the 3D printer product accommodated in the accommodation space under each of a first condition corresponding to a non-vacuum air atmosphere and a second condition corresponding to a vacuum state;
a vacuum pump connected to the chamber to form a vacuum in the chamber;
an air injection member connected to the chamber to remove a vacuum by injecting air into the chamber;
a plurality of light source modules which are members installed inside the chamber to irradiate light for the curing process to the 3D printer product, and consist of at least one first light emitting element generating ultraviolet UV and at least one second light emitting element generating light having a wavelength longer than that of ultraviolet UV;
a pedestal which is rotated and mounted inside the chamber; and
a drive actuator for rotating the pedestal,
wherein the chamber includes a main body and a lid,
the lid is configured to rotate around a rotation shaft unit provided at one side of the main body to be opened and be closed along a lateral direction against the main body,
the plurality of light source modules include an upper light source module installed on a bottom surface of the lid, and the wiring connected to the upper light source module is disposed to pass through the inside of the rotation shaft unit so that the wiring may not be exposed to the outside.
