Abstract

The invention provides a sterilizing illuminating system for a forming chamber of a biological 3D printer. The sterilizing illuminating system for the forming chamber of the biological 3D printer comprises a shell and a support plate which is arranged at the bottom of the shell; the shell and the support plate are encircled into a chamber; a light diffusion plate is arranged on one side of the support plate; a first air inlet, a second air inlet and an air outlet are formed on the other side of the support plate; a first switch device is arranged on the first air inlet; an air processor and a second switch device are arranged on the second air inlet; an air draft device is arranged at the air outlet; an LED lamp and a ultraviolet lamp are arranged on the positions, corresponding to the light diffusion plate, on the inner wall of the top of the shell; the ultraviolet lamp is capable of generating short-wave ultraviolet rays and vacuum ultraviolet rays; and an ozone concentration sensor is arranged in the chamber encircled by the shell and the support plate. The invention also provides the 3D printer with the sterilizing illuminating system. The invention utilizes the manner of mutual cooperation of the ultraviolet rays in two specific wavebands to achieve the purpose of efficiently seamless sterilizing of the airtight forming chamber of the biological 3D printer.

Description

technical field [0001] The present invention relates to the technical field of 3D printing equipment, and more specifically, to a bio-3D printer molding room sterilization lighting system and a bio-3D printer. Background technique [0002] Bio-3D printing technology uses the principle of 3D printing to directly print biocompatible materials or cells into the required three-dimensional structure. Bio-3D printing technology has extremely high requirements on the environment in the molding room, so the molding room needs to be sterilized before bio-3D printing starts. Commonly used sterilization methods include heat sterilization and ultraviolet sterilization. Among them, thermal sterilization mainly uses high temperature to denature or coagulate bacterial proteins, and metabolic disorders occur, resulting in the death of bacteria. More typical ones include incineration, boiling, pasteurization, and high-pressure steam sterilization. Due to the inherent use limitations of th...
