Description
【Technical field】
The present invention relates to a kind of 3D printing device.
【Background technology】
Also known as Introduction To Stereolithography, its principle is that computer controls laser beam is original to photosensitive resin to SLA
The surface of material carries out point by point scanning, and the thin resin layer in scanned region produces photopolymerization reaction and solidifies, and forms of product
Thin layer.Workbench moves down a distance for thickness, so that the resin surface being cured applies the new liquid resin of last layer again, carries out
Next layer of scanning machining, so repeatedly, until the manufacture of whole product prototype is finished.
But actual when using, the above-mentioned 3D printing device based on SLA also has drawback：Under shaping workpiece is every
The thickness of one layer of drop, sandwich can apply one layer of resin on the surface of shaping workpiece, and laser beam is scanned resin, Ran Houcheng
Type.But often one layer of printing, sandwich will be moved once, until workpiece printing is completed, can so take whole printing
A very long time of process, efficiency is very low, high cost.
The present invention is namely based on problem above generation.
【The content of the invention】
The purpose of the present invention is directed to the deficiencies in the prior art, proposes a kind of 3D printing device, and the device printing effect is high,
Low cost.
In order to solve the above technical problems, the present invention provides following technical scheme：A kind of 3D printing device, it is characterised in that
Including：The forming cavity that solidification equipment and the light for being sent for solidification equipment are injected, described forming cavity is beaten built with liquid
Print material, be additionally provided with the forming cavity light penetration that can be sent for solidification equipment pressing mechanism and can in forming cavity phase
For flattening the shaped platform that mechanism lifts；Described pressing mechanism lower surface is provided with PET mould release membrances.
A kind of 3D printing device as described above, it is characterised in that：Described pressing mechanism uses glass material.
A kind of 3D printing device as described above, it is characterised in that：Described pressing mechanism lower surface prints material with liquid
Material upper surface is concordant or positioned at liquid printed material upper surface lower section.
A kind of 3D printing device as described above, it is characterised in that：Described liquid printed material is photosensitive resin.
A kind of 3D printing device as described above, it is characterised in that：The solidification equipment is ultraviolet light generator.
A kind of 3D printing device as described above, it is characterised in that：The driving shaped platform is provided with the forming cavity
The elevating mechanism of lifting.
Compared with prior art, a kind of 3D printing device of the invention, has the advantages that：
The present invention flattens mechanism and is not required to using sandwich of the mechanism instead of current SLA3D printers, print procedure is flattened
Move up and down, save the time that strikes off of 3D printing, lift the overall time of 3D printing, and glass is attached to using PET mould release membrances
Glass lower section, printable layer and glass isolation technics, the layer after completing printing are separated with glass, improve printing effect, are reduced into
This.
【Brief description of the drawings】
Specific embodiment of the invention is described in further detail below in conjunction with the accompanying drawings, wherein：
Fig. 1 is a kind of topology view of 3D printing device of the invention；
Brief description of the drawings：1st, solidification equipment；2nd, forming cavity；3rd, liquid printed material；4th, shaped platform；5th, mechanism is flattened；6、
Elevating mechanism.
【Specific embodiment】
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described.
As shown in figure 1, a kind of 3D printing device, including：Solidification equipment 1 and the light for being sent for solidification equipment 1 are penetrated
The forming cavity 2 for entering, built with liquid printed material 3, being additionally provided with the forming cavity 2 can supply solidification equipment 1 to described forming cavity 2
The pressing mechanism 5 of the light penetration for sending and the shaped platform 4 that can be lifted relative to pressing mechanism 5 in forming cavity 2；Described
Flatten the lower surface of mechanism 5 and be provided with PET mould release membrances.
The present invention is applied to SLA printing techniques, it is also possible in using the 3D printing technique in DLP/CLIP, do not make herein
It is specific to limit.
In print procedure, one layer is often printed, shaped platform can decline, it is flat that liquid printed material can automatically be filled into shaping
Gap between platform and pressing mechanism, and liquid printed material 3 is consolidated when the light penetration that solidification equipment 1 sends flattens mechanism 5
After change, the upper surface of printed material can coincide with the underside shape for flattening mechanism, it is not necessary to which sandwich is to be capable of achieving plane
Effect, saves the time-write interval, and the lower surface of pressing mechanism is provided with PET mould release membrances, layer and press after completing printing
Structure is separated, and printing effect is high.
Described pressing mechanism 5 is provided with PET mould release membrances using glass material and lower surface, is available for the light that solidification equipment sends
Line is penetrated, and the layer after completing printing is separated with glass, and printing effect is high, and material is not specifically limited herein.
As described in Figure 1, in the present embodiment, the described lower surface of pressing mechanism 5 is concordant with the upper surface of liquid printed material 3
Or positioned at the upper surface of liquid printed material 3 lower section；The operating position of current printable layer is placed on below liquid printed material horizontal plane,
Degree of regulation to whole printing process liquid printed material is less demanding, reduces machine manufacturing cost.
As described in Figure 1, in the present embodiment, described liquid printed material 3 is photosensitive resin.Using photosensitive resin by purple
The principle of outer light irradiation solidification.
As described in Figure 1, in the present embodiment, the solidification equipment 1 is ultraviolet light generator.
As described in Figure 1, in the present embodiment, the lift for driving the lifting of shaped platform 4 is provided with the forming cavity 2
