Description
[technical field]
The present invention relates to a kind of 3D printing technique field, especially relate to and a kind ofly print the 3D Method of printing and 3D printer that workpiece strength significantly improves.
[background technology]
The operation principle of 3D printer is substantially identical with normal printer, is by conputer controlled, " printed material " to be stacked up from level to level, and finally the blueprint on computer is become in kind, this is a technological revolution of overturning conventional fabrication processes.
Common 3D printer operating speed is very slow and expensive, if will improve the printing effect of common 3D printer, then need the filling rate of filling rate parameter to reduce, the reduction of filling rate then causes the density of the object printed to reduce, intensity difference.
Therefore, common 3D printer can only use in places such as scientific research institutions, and 3D printing technique can't wide popularization and application.
Chinese patent mandate publication number: CN101531103A, authorizes publication date on May 18th, 2011, discloses a kind of printer control method and printer.Comprise the following steps: store the configuration information comprising the first data or the first order, described first data or the first order are used for making described printer based on buzzer configuration order, described buzzer be sounded a buzzer; And described printer makes described buzzer sound a buzzer based on described first data or the first order.Weak point is, the printer of this invention can not be used for 3D and print.The operation principle of 3D printer is substantially identical with normal printer, is by conputer controlled, " printed material " to be stacked up from level to level, and finally the blueprint on computer is become in kind, this is a technological revolution of overturning conventional fabrication processes.
3D prints and directly utilizes the threedimensional model of Computer Design, without the need to cutting tools and mould, by by point to line, by line to face, by face to minute layer scattering of body and banking process, realize the manufacture of complex parts fast.At present, on market, existing various business-like 3D Method of printing and equipment thereof, comprise photocuring processes, fusion sediment method, precinct laser sintering method etc.But existing 3D printing technique majority is optimized for the size and precision that need the model printed, and that will beat exactly in brief is larger, faster and more smooth.But these models cannot reflect the more information of design, such as reasonable structure, weak spot and stability etc., cannot obtain the data such as stress, strain, deformation, these attributes are not just only bring by outward appearance, more need the mechanics feature that can obtain 3D printer model.
But, the mode that 3D known at present successively prints, in concrete print procedure, be all almost be n many layers by 3D model decomposition, every layer resolves into a concrete pictures, each picture is in the mode of pixel, according to X-direction from 0 to end, resolve into several lines, in the Y-direction of each line, according to the presence or absence of pixel, carry out in the Y direction from 0 to end the printing of individual element; This printing is similar to the printing type of ink-jet printer.

……
This mode print speed is very fast, and algorithm is simple, is high efficiency for modelling print component.Shortcoming is but, owing to not considering the interaction of the fiber between crystalline growth between the material between points that each 3D prints or different solidifications, create the workpiece of same material, the same workpiece of the workpiece ratio machining that 3D prints, or injection mold produces workpiece, intensity there are differences.The workpiece outward appearance that result in 3D printing is the same with the workpiece of machining, but but can only make model because intrinsic strength is defective, and can not practical application.Say on the other hand, consume same material, the inherent quality of the workpiece obtained is defective, is also a kind of waste.
Publication No. CN104441666A polar coordinates type 3D printer, also fails to improve for the purpose of inside workpiece intensity, also only because add circular base plate, and improves speed of production and the production efficiency facilitating twist mode workpiece.If but there is serious eccentric phenomena in some aspect that also there is processing work, even the base center of circle is positioned at certain layer of outer end of workpiece, polar coordinates print and will encounter difficulties, and the print head row inbound path that can not control the workpiece of this aspect is suitable strength, or even expected.
The 3D Method of printing of application number 201410142105.0 and 3D print system, one synchronizing control is set, during printing, Synchronization Control drives circular print platform rotate around center of circle rotating shaft and decline, and makes shaping printable layer form helical form on whole circular print platform; The position of slice of data in object of described print data information is consistent with the helical lay of printing objects with shape.Simultaneously the goal of the invention of application number 201410142105.0 realizes multilayer in a printing interval to print, and improves print speed, be conducive to strengthening inter-layer bonding force.If but serious eccentric phenomena appears in some aspect that also there is processing work, even the base center of circle is positioned at certain layer of outer end of workpiece, owing to can not adjust the processing work center of circle in time, if take the printing of polar coordinate model to encounter difficulties.Let alone raising workpiece strength.
Background technology does not have the causality of machining path and the workpiece microstrength considering that shower nozzle is walked, and can not carry out designing and calculating targetedly.
Can when using identical material with identical 3D printing device, is the workpiece strength that 3D prints higher? what finally make 3D print is no longer model but operable workpiece.Three-dimensional printing technology is advanced to field of industrialized production.Or can allow the workpiece that plastics print, in use with performance 3D printer, identical 3D processing model, and is the workpiece outward appearance of three-dimensional printing more smooth?
[summary of the invention]
