Description
Technical field
The present invention relates to a kind of 3D printer based on DLP photocurings, belongs to 3D printing technique field.
Background technology
Stereolithography（DLP）Technology is to study that most deep, technology is most ripe, most widely used one kind in the world at present
3 D-printing forming technique.Stereolithography printer（DLP printers）With light-cured resin as moulding material, with ultraviolet light or
Other light source irradiations, cause photochemical reaction, make the liquid photocurable resin curing molding being exposed.
DLP photocurings 3D printer includes printer frame, projector light source, printing shaping platform and resin storage tank, DLP
Printer drives printing shaping platform to move up and down in resin storage tank by vertical lifting mechanism, and resin storage tank is built with light
Solidified resin, it is poly- that projector light source projects to the light-cured resin moment contacted with light in the bottom of resin storage tank, such resin storage tank
Synthesis of solid, and the light-cured resin not contacted with light then keeps liquid, thus in printing shaping platform and light-cured resin
Three-dimensional body is successively generated in the relative plane of groove.
But in prior art, the bottom of profiled member is attached to first on printing shaping platform, then solidification superposition from level to level
Model is finally produced in molding.DLP printers after the completion of printing, when removing printed model from printing shaping platform, one
As be all shoveled from printing shaping platform with scoop under, and scoop shovel drag when, the bottom lifting surface area of model is little, and receives
Power is uneven, it is easy to the bottom of damage model, makes waste product, so as to reduce printing effect（Percent defective is improved）.
In addition, DLP printers are in solidification superposition molding from level to level, layer is changed every time and is intended to make profiled member and resin storage tank point
From, but after printing one layer, printing objects layer is still within the light-cured resin of liquid, so in printing shaping platform upwards
When mobile, need to overcome the cohesive force between profiled member and printing shaping platform, make printing objects layer and light-cured resin bottom land
Face so can not only affect the stripping result of printing objects layer in the rigid disengagement of vertical direction, and finally have a strong impact on object
Molding effect, so that the percent defective of printout is improved, but also can affect the overall service life of printer.
The content of the invention
The invention solves the problems that technical problem is：A kind of percent defective that can reduce printout is provided and prints effect so as to improve
The 3D printer of the employing DLP technologies of rate.
In order to solve above-mentioned technical problem, technical scheme proposed by the present invention is：A kind of 3D printing based on DLP photocurings
Machine, including workbench, vertical lifting mechanism, projector light source and the resin storage tank that is fixed on the workbench, the projection
Instrument light source is connected with printing shaping platform towards resin storage tank, the bottom of the vertical lifting mechanism；The printing shaping platform bag
Handle, push rod, base plate and by the affixed top board of side plate and base plate are included, the base plate, side plate, top board combine to form framework knot
Structure；It is provided with fixed plate in the frame structure, the base plate is provided with the through hole for being available for the push rod to pass through, the one of the push rod
End is affixed with fixed plate, and the other end of push rod insertion through hole simultaneously can be moved back and forth up and down along the through hole, the handle and
Top board is threadedly coupled and affixed with fixed plate after through top board；The resin storage tank is disc, and the resin storage tank is by rotation
Driving means can single direction rotation；The resin storage tank is divided into the fanned partition of at least two equalizations, and the size of each fanned partition is equal
It is adapted with the printing shaping platform；The 3D printer in successively printer model, the bottom of the push rod and base plate
Bottom surface flushes, and after printing completes a layer model, the resin storage tank rotates a fanned partition, and the vertical lifting mechanism drives
Printing shaping platform to be lifted and print next layer model after predetermined altitude, when the 3D printer is printed completes the demoulding, the handss
Handle rotation driving fixed plate and push rod are moved down and ejected from base plate so as to print the model for completing.
The beneficial effect that the present invention brings is：
1）The present invention arranges push rod in fixed plate, and constitutes differential screw body by handle, top board, fixed plate so that Gu
Fixed board enough realizes faster reciprocal motion, so as to drive the push rod in fixed plate to eject on printed model on base plate, no
But printing effect is not affected in print procedure, and can be overcome in prior art with the model that scoop is printed under shovel
When, the defect of model is easily destroyed, and then improve printing effect（Percent defective is reduced）.
2), in solidification superposition molding from level to level, layer is changed every time separates profiled member and resin storage tank to printer of the invention
When, profiled member is moved horizontally along the bottom surface of resin storage tank by the rotation of resin storage tank first and separate, then in the vertical liter
The drive printing shaping platform of descending mechanism is lifted up, so that profiled member lifts predetermined altitude, it is convenient to print next layer model.
Before exactly because profiled member is separated with resin storage tank, first along moving horizontally along the bottom surface of resin storage tank, in the support of resin groove bottom
Lower profiled member do not allow when mobile it is fragile, when vertical lifting mechanism described in adornment lifts the profiled member demoulding, profiled member and resin storage tank
Between cohesive force almost no longer existed, therefore stripping result is substantially improved, and reduce further the printing effect of printer
Rate, i.e. percent defective are further reduced.
The further improvement of above-mentioned technical proposal is：The top surface of the base plate has sticked one layer of sealing gasket, the sealing gasket
The junction of through hole and push rod is sealed.Can so prevent resin from the top surface of base plate is penetrated into from the through hole of base plate, it is to avoid shadow
Ring the print quality of model and remove the efficiency of model from printing shaping platform.
Preferably, the handle includes Flos Mume bakelite handle and the stud being fixed on the Flos Mume bakelite handle, described
Stud is threadedly coupled with top board and its one end is affixed with fixed plate.
Preferably, the base plate and side plate are formed in one structure, and the top board is affixed with side plate by trip bolt.
Preferably, the push rod has multiple, is evenly distributed in fixed plate；Correspondingly, the through hole also has multiple, uniformly
It is distributed on base plate.
