Description
Technical field
The utility model is related 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）Using light-cured resin as moulding material, with ultraviolet light or
Other light source irradiations, trigger 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 can be moved up and down by vertical lifting mechanism drive printing shaping platform in resin storage tank, 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 in the bottom of resin storage tank, such resin storage tank with light
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 the prior art, the bottom of molding part is attached on printing shaping platform first, then solidification superposition from level to level
Shaping finally produces model.DLP printers are after the completion of printing, when removing printed model from printing shaping platform, and one
As be all that and scoop is when shoveling drag under being shoveled with scoop from printing shaping platform, the bottom lifting surface area of model is small, and by
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 shaping from level to level, layer is changed every time and is intended to make molding part and resin storage tank point
From, but after printing one layer, printing objects layer is still within the light-cured resin of liquid, so upward in printing shaping platform
, it is necessary to overcome the cohesive force between molding part and printing shaping platform when mobile, make printing objects layer and light-cured resin bottom land
Face is disengaged in vertical direction hardness, so can not only influence the stripping result of printing objects layer, and finally has a strong impact on object
Molding effect, so that the percent defective of printout is improved, but also can influence the overall service life of printer.
The content of the invention
The utility model will solve technical problem：A kind of percent defective that can reduce printout is provided to beat so as to improve
Print the 3D printer of the use DLP technologies of efficiency.
In order to solve the above-mentioned technical problem, the utility model proposes technical scheme be：A kind of 3D based on DLP photocurings
Printer, including workbench, vertical lifting mechanism, projector light source and the resin storage tank being fixed on the workbench, it is described
Projector light source is connected with printing shaping platform towards resin storage tank, the bottom of the vertical lifting mechanism；The printing shaping is put down
Platform includes handle, push rod, base plate and by the affixed top board of side plate and base plate, and the base plate, side plate, top board combine to form frame
Frame structure；Fixed plate is provided with the frame structure, the base plate is provided with and is available for the through hole that the push rod is passed through, the push rod
One end and fixed plate it is affixed, the other end of push rod insertion through hole can simultaneously be moved back and forth up and down, the hand along the through hole
Handle is threadedly coupled with top board and through affixed with fixed plate after top board；The resin storage tank is disc, and the resin storage tank passes through
Rotating driving device can single direction rotation；The resin storage tank is divided at least two impartial fanned partitions, each fanned partition it is big
It is small to be adapted with the printing shaping platform；The 3D printer is in successively printer model, the bottom and bottom of the push rod
The bottom surface of plate is flushed, and after printing completes a layer model, the resin storage tank rotates a fanned partition, the vertical lifting mechanism
Next layer model is printed after driving printing shaping platform lifting predetermined altitude, when 3D printer printing completes the demoulding, institute
State rotatable handle driving fixed plate and push rod is moved down and ejected so as to print the model completed from base plate.
The beneficial effect that the utility model is brought is：
1）The utility model sets push rod in fixed plate, and constitutes differential screw mandrel machine by handle, top board, fixed plate
Structure so that fixed plate enough realizes faster reciprocal motion, so as to drive push rod in fixed plate by printed mould on base plate
Type is ejected, and does not influence printing effect in print procedure not only, and can overcome use in the prior art scoop to be printed under shovel
During the model got well, the defect of model is easily destroyed, and then improve printing effect（Percent defective is reduced）.
2) printer of the present utility model is in solidification superposition shaping from level to level, and layer is changed every time makes molding part and resin storage tank point
From when, bottom surface of the molding part along resin storage tank is moved horizontally and is separated by the rotation of resin storage tank first, then described vertical
The drive printing shaping platform of elevating mechanism is lifted up, so that molding part lifts predetermined altitude, next layer of mould of convenient printing
Type.Before exactly because molding part is separated with resin storage tank, first along being moved horizontally along the bottom surface of resin storage tank, in the branch of resin groove bottom
The lower molding part of support do not allow when mobile it is fragile, described in adornment during the vertical lifting mechanism lifting molding part demoulding, molding part and resin
Cohesive force between groove has almost no longer been present, therefore stripping result is substantially improved, and reduce further the printing of printer
Efficiency, 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.It can so prevent that resin from penetrating into the top surface of base plate from the through hole of base plate, it is to avoid shadow
Ring the print quality of model and the efficiency of model is removed from printing shaping platform.
It is preferred that, the handle includes plum blossom bakelite handle and the stud being fixed on the plum blossom bakelite handle, described
Stud is threadedly coupled with top board and its one end and fixed plate are affixed.
It is preferred that, the base plate and side plate are formed in one structure, and the top board is affixed with side plate by trip bolt.
It is preferred that, 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.
