Problems solved by technology

It is also known that a household 3D printer using SLA puts a photosensitive resin on the material container, and the photosensitive resin receives the corresponding light wavelength to achieve curing and molding. However, to form a colored layered stacked entity, it is necessary to mix the photosensitive resin. Made with dyes, due to the uneven distribution of dyes in the photosensitive resin of the container, the color of the layered solid body is uneven

Abstract

A three-dimensional printer comprises a housing, a stirring mechanism, a laser mechanism, a scanning mechanism and a molding platform. The housing is provided with an internal space. The stirring mechanism is arranged in the internal space, and comprises a container, a transferring unit and a fan blade. The container defines a material holding space. The container comprises a substrate extending horizontally, and an upper opening opposite to the substrate and communicated to the material holding space. The substrate is provided with a first side and a second side opposite to the first side, and the first and second sides are located in the first direction. The transferring unit can move to the second side from the first side relative to the substrate. The fan blade is arranged in the material holding space in the direction parallel to the first direction, is located on the substrate, is connected to the transferring unit, and can move along the first direction under the driving of the transferring unit.

Description

technical field [0001] The invention relates to a stirring mechanism and a three-dimensional printer, in particular to a stirring mechanism and a three-dimensional printer suitable for stereolithography. Background technique [0002] Rapid Prototyping (RP) can quickly manufacture 3DCAD, test the assembly of parts, and do further functional tests. 3D printing is one of the rapid prototyping technologies. 3D printing is based on digital model files, using powdered metal or plastic and other bonding materials to construct entities by layer-by-layer stacking. [0003] Stereolithography (SLA) is a method of 3D printing. For example, US20130337100A1 discloses a stereolithography machine for manufacturing three-dimensional objects. It is also known that a household 3D printer using SLA puts a photosensitive resin on the material container, and the photosensitive resin receives the corresponding light wavelength to achieve curing and molding. However, to form a colored layered st...
