Embodiment Construction
[0029] Such as figure 1 As shown, the rapid prototyping device based on the ultraviolet exposure dynamic mask technology includes a resin tank 1, a closed air chamber 2, a long-wave ultraviolet light source, a short-wave ultraviolet light source and a control host 5. The closed air chamber 2 is set in the resin tank 1 Below, the light emitted by the long-wave ultraviolet light source and the short-wave ultraviolet light source is incident into the resin tank 1 through the closed air chamber, and the liquid photosensitive resin is housed in the resin tank 1, and can be cured under the irradiation of long-wave ultraviolet light 3; Oxygen 6 is housed in the enclosed air chamber, and the short-wave ultraviolet light source projects short-wave ultraviolet light 4 to the oxygen in the enclosed air chamber according to the specific shape of the forming and processing layered slices, making it react to generate ozone, and making the enclosed air chamber 2 The local projection area of ...
