3D printing is novel rapid prototyping ＆ manufacturing technology.It manufactures product by multiple-layer stacked growing principle.It can overcome
The special construction obstacle that tradition machinery processing can not be realized.It can realize the simplification production of arbitrarily complicated structure member.It is existing
3D printing technique be divided into:Thermoplastic cement technology FDM；Laser sintering and moulding technology；Photocurable liquid Choice of Resin is regions curing
Forming technique.And liquid resin selection region curing molding technology be divided into for：Laser scanning imaging photocuring technology (SLA)；It throws
Shadow instrument image conversion irradiation forming technique (DLP)；Display screen is imaged ultraviolet frequency spectrum photocuring technology (LCD).
LCD photocuring principles are, using liquid crystal display LCD image-forming principles, in microcomputer and display drive circuit
Under driving, picture signal is provided by computer program.Occurs selective black and white region on LCD screen, white is transparent area
Domain, black are lightproof area.
Under the irradiation of light source (the generally larger high frequency ultraviolet light of radiation energy), the images transparent region of LCD screen
Ultraviolet light is obstructed and is reduced, ultraviolet light can penetrate；In the region that no image is shown, ultraviolet light is blocked.Through liquid crystal
The ultraviolet light of screen forms ultraviolet light image region.
In the surface mount photocurable liquid resin storage tank of LCD screen, slot bottom is transparent membrane, and ultraviolet light is by transparent
Film is irradiated to liquid photocurable resin, makes to generate curing reflection, the liquid resin being irradiated to by the resin of ultraviolet light
As solid-state.LCD screen lighttight partial occlusion ultraviolet light.Be blocked part liquid photocurable resin not by
Ultraviolet light is irradiated to, and the part resin not being irradiated to still maintains liquid.It is exactly that our 3D are beaten by cured resin
The formed product part of print machine manufacture.
LCD uv equipments light source has very strong heat radiation, and long-term radiation can seriously affect the use longevity of liquid crystal display
Life, radiant heat are excessive it is also possible to damage liquid crystal display；In addition resin solidification can also generate certain heat, can all act on liquid crystal
Screen.
It is to sum up chatted, needs a kind of liquid crystal display cooling module-coldplate, to solve the problems, such as that liquid crystal display heats up, therefore, this hair
A person of good sense designs a kind of LCD liquid crystal display coldplates based on LCD photocuring 3D printers.
