Kind Code:
A1
Abstract:
Provided in the embodiments of the present application is a photo-curing 3D printing device, by means of which liquid photo-curing resin is cured by means of light irradiation to achieve 3D printing. The photo-curing 3D printing device comprises: a body cover, which defines an internal space; and a first circulation assembly, which is arranged in the internal space for heating and filtering the gas in the internal space, wherein a first gas cavity is defined inside the first circulation assembly; the first circulation assembly comprises a first gas driving unit, a heating unit and a first filtering unit, which are arranged in the first gas cavity and spaced apart from each other; and the first gas driving unit is configured such that the gas outside the first gas cavity is sucked into the first gas cavity, passes through the heating unit and the first filtering unit, and is then delivered to the outside of the first gas cavity. The photo-curing 3D printing device can perform filtration, purification and temperature control for the internal gas environment.
