Description
Technical field
The utility model relates to a kind of LCD 3D printers, more particularly to a kind of rapid photocuring LCD 3D printer.
Background technique
3D printing technique is a kind of present hot technology of increasing material manufacturing, is different from traditional material that subtracts and fabricates industry,
It manufactures product by multiple-layer stacked growing principle, tradition machinery can be overcome to process the special construction obstacle that cannot achieve, in work
There is very big advantage in industry production, the simplification production of arbitrarily complicated structure member may be implemented.One such 3D printing skill
Art is known as photocuring 3D printing, technically simple to rapidly become research hotspot because its equipment volume is small.Existing photocuring 3D printing
Technology is divided into laser three-dimensional printing technology SLA (laser point light source solidification), DLP (solidification of projector area source) and LCD (liquid crystal
Area source solidification) 3 kinds.LCD printer used in now uses color LCD luminescent screen, and most of light source used is can
Light-exposed, it is visible light photo initiators that this, which allows for added photoinitiator in corresponding resin material, it is expensive and
It is difficult to save.Existing part LCD uses ultraviolet light as light source by improvement, but still uses color LCD screen.Color LCD
The color filtration layer shown in screen containing special disposal colour, each pixel there are three liquid crystal cells lattice at,
In have red respectively before each cell, green, or the filter of blue, this will make uv transmittance significantly
It reduces, harshness is required to photosensitive resin, printing success rate is low.
Utility model content
It can be improved the rapid photocuring of printing precision, speed and success rate the purpose of this utility model is to provide a kind of
LCD 3D printer.
This rapid photocuring LCD 3D printer provided by the utility model, it includes rack and is arranged on
Z axis motion module, resin storage tank, LCD liquid crystal display and light source, be connected with liftable shaped platform in Z axis motion module, form
From top to bottom successively to positive setting, the bottom surface of resin storage tank is transparent mould, the light source for platform, resin storage tank, LCD liquid crystal display and light source
For ultraviolet source, the LCD liquid crystal display is black-and-white crystal screen.
The LCD liquid crystal display is to input playing function and high-precision black white liquid crystal of the screen resolution not less than 1K with picture
Screen.
The ultraviolet source includes the ultraviolet lamp bead of 405nm and matched cooling system.
The rack includes upper and lower two layers, and upper layer is equipped with loophole, and the LCD liquid crystal display is installed at the loophole of upper layer,
The light source is installed on the lower layer of rack.
The bracket further includes the armstand being vertically arranged, and the top of armstand is equipped with installation plate, and the Z axis motion module is set
It is placed between installation plate and the upper layer of bracket.
The Z axis motion module is the screw rod slide unit of step motor control.
