Background technique
Digital light processing (Digital Light Processing, DLP) is the 3D printing technique occurred in recent years, is being processed
When product, using digital micromirror elements by product cross section graphic projection to liquid light resin surface, keep the resin of irradiation layer-by-layer
Carry out photocuring.Digital light processing projector is using digital micro-mirror device dmd chip as image device.By adjusting micro mirror
The instrument of angle realization reflective projection.The 3D printer of the Miniature digital light processing projection device used on the market at present all makes
With single side overlaying structure, each layer of figure of printer model only has a secondary tangent-plane projection to be formed by curing, printing surface and throwing
Shadow face is overlapped, and advantage is that structure is simple, and print speed is fast.But if wanting to increase the effective area printed, projected according to amplification
The method in face, the then dpi that can reduce perspective plane sacrifice printing precision significantly, according to the side on the more big perspective planes of projector splicing
Method can make cost double, then will increase number of motors using the method for mobile projector instrument or optical path, destroy its simple structure
The introduction meeting of motor is so that error increases simultaneously, it is clear that is not the technology of mature and feasible, is not able to satisfy the demand of significant market.
Summary of the invention
The shortcomings that it is a primary object of the present invention to overcome the prior art and deficiency, provide a kind of 3D printing mechanism, are protecting
Holding on the basis of resolution ratio printing effective area and will expand as original several times, realize larger sized micro-lithography 3D printing.
The purpose of the present invention is realized by the following technical solution: a kind of 3D printing mechanism, including printing portion and promotion
Part；
The printing portion includes objective table, first motor, digital optical processing projector, resin storage tank；
Objective table is connected with first motor, and band dynamic object stage rotates when first motor works；
The projection plane that digital optical processing projector projects is through resin storage tank and is imprinted at least partly objective table；
The objective table of the lift portion connection printing portion.
Preferably, the lift portion includes the second motor, objective table load-bearing axle, the screw being threadedly coupled with load-bearing axle
Bar, the rotation of the second motor driven screw rod, and then moved with dynamic object stage load-bearing axle along screw rod length direction.
Further, limit plate is installed in the screw rod, to prevent objective table load-bearing axle from falling off.
Preferably, the objective table is circle, to reduce printing mechanism volume.
Preferably, the printing portion includes fixed disk, support rod, and fixed disk is installed on support rod and can opposite support
Bar rotation；Projector is installed in fixed disk；First motor drives a fixed disc spins step of going forward side by side to drive projector rotation.
Further, the first motor output shaft is equipped with first gear, the fixed disk and support rod junction
Second gear is installed, second gear is relatively fixed with fixed disk, and first gear is engaged with second gear.
Further, the fixed disk is equipped with several engraved structures, in order to fixed projector.
Compared with the prior art, the invention has the following advantages and beneficial effects:
1, the present invention is only added to a motor in the prior art, realizes the function of several times area increase, structure letter
Single, energy consumption is few.
2, printing precision is not sacrificed while the present invention increases print area, meets large scale high-precision printing demand.
