The special construction obstacle that tradition machinery processing can not be realized, it is possible to achieve the simplification production of arbitrarily complicated structure member.
Nearly 2 years, photosensitive resin had just been used for 3D printing emerging industry, interest in industry because of its outstanding characteristic
With attention.Current imaging technique uses laser, projection or scanning.But current laser or project or scanning all
There is light path to distribute, it is necessary to which very big equipment size configures to meet light path.And existing projecting apparatus light by repeatedly into
As optical skew will occur for figure after lens, although deformation is very small, but the accuracy of manufacture can not ensure.It is given birth to
The product of production can not reach industrial class precision.
Utility model content
The utility model provides a kind of imaging system for photosensitive resin 3D printing, by being layered projection model section
Ultraviolet light, reach the purpose of multi-shell curing liquid photosensitive resin.

Display screen, Fresnel Lenses, light collecting barrel, ultraviolet light source, LCD liquid crystal display screen drive module and computer；Wherein, it is described
LCD liquid crystal display screen is close to the Fresnel Lenses, and the Fresnel Lenses is arranged in the upper port of the light collecting barrel, described
The lower ports of light collecting barrel are arranged on the ultraviolet light source.
The axis of the light collecting barrel and the ultraviolet light source is overlapped.
The light collecting barrel flare, upper port is big, and lower ports are small.
The wavelength of the ultraviolet light source is 400nm -420nm.
The ultraviolet light source is integrated purple LED lamp bead.
The prefocus cup is light tight, interior painting optically focused coating.
Imaging system described in the utility model for photosensitive resin 3D printing, is thrown ultraviolet light source by light collecting barrel
The ultraviolet light aggregation penetrated, injects Fresnel Lenses, the ultraviolet light of multi-direction injection is transformed into uniform UV by Fresnel Lenses
Light, it is vertical to inject LCD LCD screens；Meanwhile, manipulation of the LCD LCD screens in computer and LCD liquid crystal display screen drive module
Under, the sectional view of the printing workpiece of display white, uniform UV light permeability sectional view successively solidifies liquid photosensitive tree
Fat.On LCDs, the white portion on uniform ultraviolet-transparent LCDs, and can not pass through and not show figure
The black region of shape, so as to reach the ultraviolet light in layering projection model section, the purpose of multi-shell curing liquid photosensitive resin, figure
Deformation form quotient is low, and the Product Precision of production is high；Light path configuration is met without very big equipment size.
