Description
Technical field
The RF identification and method for parameter configuration and the device that the present invention relates to a kind of 3 D-printing consumptive material, belong to the identification of 3 D-printing consumptive material and the storage of parameter, quantification and operation technique field.
Background technology
At present, traditional fuse is piled up moulding (Fused Deposition Modeling FDM) three-dimensional printer, be again hot-melt extruded formula three-dimensional printer, the particularly molten extruded type three-dimensional printer of desktop type, because cheap, 3 D-printing consumptive material is easy to get, and its application is also more and more wider, has increasing producer to provide fuse to be piled into pattern three-dimensional printer and corresponding 3 D-printing consumptive material both at home and abroad.This patent mainly describes around FDM class three-dimensional printer.
The traditional prior art relevant according to retrieval, the 3 D-printing consumptive material of fuse stacked three-dimensional printer with the form of plastic wire, provides by spool carrier conventionally.Printer pushes this plastic wire the heater fusing of printing extruder head by drive motors, then extruded and formed filament by the nozzle of printing extruder head, this filament is understood cooling curing after leaving nozzle, and this nozzle is under computer-controlled motor, at X, Y plane is done two dimensional motion, and is printing on base plate, apart from certain altitude, filament can be extruded from nozzle, and be attached on base plate, according to the shape motion of design in advance, construct ground floor physical form.Then, nozzle relative base plate under computer control does the displacement of vertical Z direction, and on the basis of ground floor, constructs the 3D solid of the second layer and even follow-up multilayer, finally completes the printout that constructs 3D solid by the plastic filament of fusing.
The patent of piling up moulding (FDM) three-dimensional printing technology along with the fuse of Stratasys lost efficacy, and had emerged in large numbers in recent years a collection of FDM of desktop type cheaply three-dimensional printer.Although these FDM three-dimensional printer costs are low, have in actual applications a series of operation and problem is set.Wherein a crucial part is exactly the setting of 3 D-printing consumptive material parameter, these parameters briefly mainly: the cooling velocity after the temperature of fusing 3 D-printing consumptive material, the speed that filament is extruded and filament are extruded.The shaping of these parameters to final printout, precision, outward appearance plays a part very crucial.
Fuse is piled into the normally just round plastic wire of 3 D-printing consumptive material that pattern desktop three-dimensional printer uses, and conventional diameter specifications has 3mm and 1.75mm.Its material is mainly ABS plastic or PLA plastics.Mobility after mobility after PLA plastic molting melts than ABS plastic is than poor, thickness more, more difficultly print desirable 3D solid, so the duty that how to configure three-dimensional printer is for using the 3 D-printing consumptive material based on PLA to print even more important.Here the duty of three-dimensional printer refers to print temperature, print speed and the cooling velocity of three-dimensional printer,
The temperature of fusing 3 D-printing consumptive material is to print the heter temperature of extruder head, be called for short print temperature, this temperature is actually a nonstandard heter temperature, the temperature sensor installation site difference of the extruder head of different three-dimensional printers, makes the actual temperature of heater inside and the temperature of temperature sensor measurement have the temperature difference on the one hand; Heater shape is different with the material of manufacturing heater on the other hand, even if cause the temperature of inner some position of heater identical, the effect of actual heat fused is also different, so, this print temperature may have different actual effects for different printers, and it more accurately says the degree of heat that is illustrated in extruder head on same printer or same model printer.Plastics are a kind of vitreums, and it does not have clear and definite fusing point, but present flowable state in certain temperature range, extruder head heating-up temperature the mobility that can have influence on after filament is extruded by nozzle is set, print temperature is higher conventionally, filament mobility is better.This mobility for the impact of 3 D-printing mainly aspect four: first aspect, that bottom arrives the tack of printing base plate, the ground floor that higher print temperature can make to print can be attached to more securely to be printed on base plate, thereby provides precise and stable printing basis for the printing of follow-up multilayer; Second aspect is the firm degree of the combination between printable layer; The third aspect is the degree of printhead wire drawing while moving between different print areas, excess Temperature, mobility is very good, can make printhead move to another print area from a print area time (such as, two legs while printing portrait), printhead still has a small amount of plastic filament to flow out, thereby on the cephalomotor track of printing, pulls out a unnecessary thinner silk, affects the outward appearance of printing precision and printing entity; Fourth aspect is to stretch out or when bridge joint having, and namely prints the unsettled or part in filament below when unsettled, prints the maintenance degree of filamentary form, print temperature is low, print filament and easily solidify, what shape kept will be quite a lot of, and performance is that the overhanging portion degree of subsiding is downwards less.Temperature is not unique for the effect of above aspect, and the speed that filament is extruded and the cooling velocity of filament also can have influence on these effects.
The speed that filament is extruded, is again print speed, refers to the speed of the relative floor level motion of printhead (if not clearly distinguish, printhead general reference is printed the heater and the injector assembly of printing extruder head of extruder head).The print speed of desktop level three-dimensional printer is conventionally at 5mm/s to 80mm/s, has more than indivedual types can reach 100mm/s.Other arrange in constant situation, obviously need filament extruded velocity faster when print speed is fast, also just need to quickly 3 D-printing consumptive material be melted.And, different print speed, 3 D-printing consumptive material is in heater time of staying difference, the effect difference of fusing, the characteristic (as mobility) of extruding filament also can be different.Like this under other the same terms, for example print temperature, different print speed can have influence on the actual effect of the 3 D-printing part printing.In addition, for reaching stable filament extruded velocity, the dimensional accuracy of 3 D-printing consumptive material itself is also very important.The dimensional accuracy of 3 D-printing consumptive material is exactly the diameter of 3 D-printing consumptive material reality.For instance, to the 3 D-printing consumptive material of 1.75mm diameter specifications, its diameter error is better than +/-0.05mm conventionally.3 D-printing consumptive material diameter is meticulous, and under theoretical actuating speed, the filament amount of extruding is just few, can make printout space increase, and reducing print quality even can not moulding; Diameter is excessively thick, extrudes filament too much, and printed material is excessive, affects equally print quality, also can make printhead internal pressure too high, affects service life.
In 3 D-printing process, the filament of fusing leaves after print-head nozzle, and hope can be solidified as early as possible, is conducive to keep the shape of three-dimensional body.But it is too fast that filament can not solidify, can affect too soon the firm degree of combination between printable layer.And setting rate also can have influence on internal stress and because the printout deformation that this internal stress causes of surface roughness, printout.While printing overhanging portion like this, often wish that filament can be cooling as early as possible, can keep better shape; And print when normal configuration, cooling velocity can slow down conventionally, obtains better intensity and surface quality.Cooling general the passing through of filament installed mini-fan on printhead side, the intensity of ventilation fan directly affects the cooling velocity of filament.So, conventionally the air flux of cooling fan is defined as to cooling velocity.
As can be seen here, if obtain good 3 D-printing effect, need at least distributing rationally of this three aspects: parameter of print temperature, print speed and cooling velocity.The 3 D-printing consumptive material of same type, the 3 D-printing consumptive material that namely stock is identical, because the variation of raw material producer, the difference of additive component in addition, its characteristic has very big difference.Current way be operating personnel by experience and test, optimize and these parameters of manual setting for printer and the 3 D-printing consumptive material of use.Even if the characteristic of printer, can carry out standardized adjusting as print temperature and 3 D-printing consumptive material drive precision; Changed 3 D-printing consumptive material or purchased after different 3 D-printing consumptive materials, user may still face a series of adjustment, and its relative complexity depends on user's individual difference.
For ensureing the quality of 3 D-printing, user needs the 3 D-printing consumptive material of high-quality, and actual market is that dragons and fishes jumbled together, personation brand, and adulterating is not strange thing.Not only reduce print performance with 3 D-printing consumptive material inferior, even can damage three-dimensional printer.For ensureing that user's rights and interests and equipment manufacturer's interests need to identify 3 D-printing consumptive material.
In addition, 3 D-printing consumptive material uses information, for example, use for the first time, namely breaks a seal the time, and residue 3 D-printing consumptive material quantity, can help user to manage better 3 D-printing consumptive material.The production information of 3 D-printing consumptive material can be conducive in the time there are quality problems, and root is reviewed by producer, modification quality.
Current fuse be piled into 3 D-printing consumptive material that pattern desktop three-dimensional printer uses be substantially by the plastic wire of certain diameter on spool, be divided into the packaging of 0.5kg to 2kg.Because plastic wire consumptive material and spool thereof, for entirety is used (that is to say and conventionally plastic wire part can not taken off to independent use), in this patent, unless stated otherwise, are referred to as 3 D-printing consumptive material by them, with simplified illustration process.These 3 D-printing consumptive materials do not have the electronic information of self-contained mark and characteristic, more lack a set of mechanism and allow 3 D-printing can automatically identify and utilize these parameters.
RF identification is RFID (Radio Frequency IDentification) technology, claim again electronic tag, radio frequency identification, it is a kind of communication technology, can identify specific objective and read and write related data by radio signals, and without setting up machinery between recognition system and specific objective or optics contacts.RFID is the common name of a class technology and product, and wherein label adds the form realization of antenna conventionally with semiconductor chip, in this patent, this implementation is generally called to RFID chip, and does not distinguish especially chip itself or connected antenna.RFID storage card is a kind of common type of RFID chip, namely a kind of way of realization of RFID chip.In this patent, data refer to the content of digitlization storage, the content of particularly storing on RFID chip; Information is the data that have specific meanings; Parameter is the one of information.
Along with cracking the raising of technology, the encryption function of some RFID chips self is cracked, and the method for simply utilizing RFID chip to identify 3 D-printing consumptive material is no longer reliable.For example, the MIFARE RFID storage card of PHILIPS Co. has just had disclosed crack method.Realizing reliable 3 D-printing consumptive material with RFID identifies and the extra resist technology of false proof needs.Show according to the result of currently available technology being carried out to coordinate indexing, current prior art is also open how by the print characteristic parametrization of 3 D-printing consumptive material and deposit RFID chip in so that three-dimensional printer is adjusted the actual duty of printing according to the print parameters of 3 D-printing consumptive material in the time printing, be print temperature, print speed and the cooling velocity of three-dimensional printer, thereby obtain the correlation technique feature of better printing effect, this is also technical problem to be solved by this invention.

Described 3 D-printing consumptive material installing component 15 can be hook.
Method of the present invention is, for every volume 3 D-printing consumptive material, RFID chip, the print parameters of storage of complex identification data, 3 D-printing consumptive material and the auxiliary parameter of 3 D-printing consumptive material are installed.The interface arrangement 14 that access is arranged on the data of storage on the RFID chip 13 on 3 D-printing consumptive material is connected with three-dimensional printer 12.Three-dimensional printer 12 is arranged on the data of storage on the RFID chip 13 on 3 D-printing consumptive material by these interface arrangement 14 access, and carries out identification and the parameter use of 3 D-printing consumptive material.Further, the operating distance of the installation site of the fixed position to RFID chip 13 and described interface arrangement 14 and described interface arrangement 14 is optimized, make 3 D-printing consumptive material not in the time of operating position, interface arrangement 14 can not have access to this and be arranged on the data of storing on the RFID chip 13 on 3 D-printing consumptive material; That is to say, described interface arrangement 14 only can be accessed the data that are arranged on storage on the RFID chip 13 on 3 D-printing consumptive material 11 of current use under normal circumstances.
