Description
Technical Field
The invention belongs to the technical field of 3D printers, and particularly relates to a post hardening device for 3D printed parts.
Background
Working principle of DLP photo-curing 3D printer: digital Light Processing (DLP) technology is employed to cure liquid photosensitive resins layer by layer using a projector.
The DLP photo-curing 3D printer mainly comprises software and hardware. The hardware part mainly comprises a printer frame, a projector, a printing platform and a resin tank. In particular, the continuous layer structure of the printing platform is immersed in a resin tank, wherein the resin tank is basically a cylinder filled with photosensitive resin, and an image signal generated by a software part is projected by a projector after digital processing (DLP), and the projected light is contacted with the photosensitive resin after passing through the bottom of the resin tank. The photosensitive resin in contact with the light is polymerized into solid (i.e. the printing layer is generally 25-30 μm thick) instantaneously, while the photosensitive resin not in contact with the light remains liquid, so that vacuum is formed between the printing layer and the inner bottom surface of the resin tank, and the printing layer is subjected to the combined action of hydraulic pressure and atmospheric pressure.
The DLP 3D printing process is a process of solidifying a photosensitive resin from a liquid to a solid by irradiating the photosensitive resin with specific light, the process is a process of converting the liquid to the solid and forming the photosensitive resin into a product, and the hardness parameters of the product produced by the primary solidification forming of the current DLP technology often cannot reach the required indexes.
