The specific embodiment
Exemplarily the present invention at length is described now with reference to accompanying drawing.Certainly embodiment only is an instance, and this instance should not be confined to specific layout with the theory of invention.Before specifying the present invention, it may be noted that to be each parts and each method step that the present invention is not limited to device, this is because these parts and method step can change.Here the notion of using only is determined being used for illustrative embodiment especially, and uses without restriction.If this external specification or in claim, use odd number or indefinite article, as long as population interconnection property does not show other implication not singlely, then this also relates to a plurality of elements.
Accompanying drawing shows a kind of device that is used for that the drop manufacturing is processed by curable material through discharging continuously, three-dimensional article 16, and this material perhaps is in the liquid phase in initial state or can liquefies.This can for example carry out thus, and promptly independent interrupted drop 15 is continuously by carrying out discharging in the discharge unit 13, until the target 16 that in structure space 17, successively obtains on target support 14.Curable material is material, the for example silicon of plasticizing, and perhaps material, the for example plastics of plasticization also or pulverulent material, wherein depend primarily on, i.e. curable material or in initial state, be in the liquid phase or can liquefy.Material also can be a fusible and material that therefore can reuse reversible under heating state.As long as other material can be through this device plasticizing and particularly can be discharged through at least one discharge unit 13 arbitrarily, so just can use these materials.
Curable material has the source and course of so-called stratiform in liquid phase.In this external source and course, the deposit of liquation arrives the inwall place.This is the most obvious in the understanding to the knowledge of injection molding technology.During the pipeline of, rectangle simple in casting, liquation injects through so-called pour point and begins to utilize the flow front of sealing to launch from this point circularly, has been full of up to liquation till the overall width of die cavity.After a while, the zone between inlet and flow front can be regarded as Approximate Design.Be full of special mobility status, " source and course " in flow front from being in, if this is this line of flow observed with reference to the coordinate system of motion together, then line of flow manifests as the source in this zone.Liquation two be adjacent to mold cavity surface, solidify rapidly material bed between flow, wherein liquation is advanced towards flow front with higher speed at the die cavity center.When liquation will arrive flow front, the velocity component of liquation reduced on flow direction, and liquation flows towards inwall obliquely, is close on the inwall until it at once.
The source and course of stratiform on the one hand based on the structure of its stratiform for produce " in alignment with " drop 15 of structure space 17 is favourable; Particularly in the design of little drop, just in time also have problems at this on the other hand, these problems make utilization become difficult by injection molding technology known devices and material conversion.Adhering to of wall caused, and material only can constitute drop difficultly, and this drop has the small size of expectation, preferably smaller or equal to 1mm
3Scope in and have the flying speed of expectation, on the other hand, the corresponding high viscosity of material is important for constituting drop shape interrupted drop, that be fit to just in time.
This difference with the material of using also is known in advance waxing.Since its viscosity can with common temperature-sensitive-or injection technology extract wax, that is to say through phoronomics, do not have the acceleration of pressing and under the situation of the pressure reduction of the drop that not have to melt, extract wax.The difference of the material of using here is, its viscosity number of degrees ten first power to power repeatedly that raise.Therefore, viscosity number of degrees curable material, dynamic are positioned between 100 and 10000 [Pas], and wherein preferably, curable material is plastics or a resin common in injection molding technology.This need handle placing the material storage device under the pressure, and this is because particularly when using little discharge port in order to obtain little drop volume, without doubt need be from greater than 10 pressure until 100MPa (100 to 1000bar).
The volume of the expectation of drop 15 preferably especially from 0.01 to 0.5mm
3Scope in, preferably from 0.05 to 0.3mm
3Scope in, and particularly preferably be at about 0.1mm
3Scope in.The diameter of discharge port 20 is especially smaller or equal to 1mm, preferably about 0.1mm.Under the situation of the injection moulding speed of very general 100 [cm/s], utilize the value that obtains 10.000 [m/s] through the volume flow on surface, this injection moulding speed is come convey materials through so-called pour point with 0.1 [mm] diameter.This has caused the source and course that has until the stratiform of the flowing velocity of 10.000m/s for liquid phase.
The common purpose of this device and its discharge unit is, from material storage device 12 with downwards until the minimum amount of several micrograms with the fluent material of high viscosity, discharge like the plastics of fusing, this material storage device is under high pressure and the possible high temperature.In the share of disperseing separately, extract the minimum/drop 15 of material, wherein can influence the size of share by device.The share of discharging has high like this kinetic energy, and promptly this share can overcome adhesive force and break away from and flow away as drop 15 from installing, so that construct object 16 in the structure space 17 on subject support 14.
Because relate to liquid but the material of high viscosity, and this material has high adhesion force and less weight, therefore transmits kinetic energy by means of the pressure reduction between material storage device 12 and the flight space that is used for drop 15 that in structure space 17, constitutes.Carry out portioning by means of (getaktet) of beat control, the dividing plate be furnished with as the nozzle needle 21 of locking device.Receive size and the restriction of adhesive characteristics of the requirement of share, usually need be at the pressure in 100MPa (1000bar) and the more scope, less than the enclosed baffle of 0.1mm with in addition less than off-period of 0.001s.Because under the most situation of material is plastics, mainly temperature in the material storage device therefore until 450 ℃.
Under this condition, this device is realized as metering units utilization sealing/contact the least possible with respect to the external world.According to Fig. 2 and 3, locking device designs the solid hinge 24 that has elastically deformable for this reason.Cross section in Fig. 3 illustrates especially, has for example related to the fixed connection portion with the mode of material bridge, but should fixed connection portion on the other hand can be through correspondingly spring ground manipulation of executing agency 26.Used nozzle needle 21 with supporting position 21a as locking device.On the side of the nozzle needle 21 of central authorities, be used to constitute the material attenuation of solid hinge 24.Executing agency can directly or through middleware act on abutment face 21b overleaf.Closing means utilizes nozzle needle 21 to seal discharging dividing plate 27.
At least one processing unit is designed for curable material is processed into and is in the liquid phase and treated material is arrived by this place and has at least one material storage device 12 of at least one discharge unit 13.But material be furnished with from this process beat control (taktbar) locking device outlet 20 on the direction of structure space 17 with the form discharging of interrupted drop 15.For necessary boundary condition is provided, the pressure generation unit that at least one is used for producing the pressure on the liquid phase that is applied to material storage device 12 is set.Material storage device 12 also can be the parts by the processing unit 11 that constitutes of plasticizing machining cell as in an embodiment.The pressure generation unit is for example at auger conveyor shown in Fig. 1 28 or similar conveying equipment then.
Nozzle needle directly is suspended on the flexible solid hinge 24, and the material storage device 12 that this solid hinge will be used for the liquid phase of material outwards seals with respect to (manipulation) executing agency 26.Therefore except the filling mouth and discharging dividing plate 27 of material storage device 12, do not need other sealing.Have similar integrated reset force because solid hinge 24 is relevant to from the executing agency 26 of external action on abutment face 21b through corresponding geometry designs, can realize thus with executing agency be connected have minimum contact-making surface, be on the material storage device high pressure and high temperature under and this effect realization that is connected the one-sided power of being relevant to.
The solid hinge 24 that constitutes thus can and for example can be designed with prestressing force like this with the realization of different geometric structure Design, and promptly discharging dividing plate 27 is closed passively or opened passively.The solid hinge can be processed by any withstand voltage and heat-resisting material, and these materials are not only metal, and for example also comprise fibre-reinforced lightweight structural material.The area that in material storage device 12 or in exit passageway 12b, bears pressure is regarding on the side of outlet 20 greater than the area in the zone of outlet 20.Nozzle needle 21 is opened passively thus.This means that executing agency 26 compresses opening on one's own initiative, perhaps opening is not through opening executing agency's feed.
Executing agency 26 can be designed as cam rotor, direct magnet (Direktmagnet) or is designed to piezoelectric element.Preferably, executing agency 26 can manually or controllably regulate under prestressed situation.Can sensor 19 be set according to Fig. 4 equally, its signal corresponding to the condition of work in the material storage device adjust again executing agency 26 the position and and then adjust the operating point again, this expands for compensation based on high pressure and high temperature is necessary.According to Fig. 4, for example power is to be detected and adjust to the power rated value again through controller 18 and adjuster 22 in controls.Possible thus is, through the pressure that is fit in material storage device 12-regulate the prestressing force of adjusting the solid hinge again corresponding to the automatic executing agency of condition of work utilization in the material storage device with temperature sensor.
Preferably, executing agency 26 is designed to the power measuring cell, so that measure and adjust the prestressing force of solid hinge 24 on the operating point.Advantageously, executing agency is a piezoelectric element.Utilize such sensor 19 and controller 18 also possible be, utilize executing agency aptly at solid hinge place travel path-/line of force road so that thus also compatibly and wittingly influence need shape, the for example drop shape of the material of discharge.
It is obvious that, can carry out being equal to modification, change and the adjustment that changes in the scope of affiliated claim on the maximum different extent to this specification.
