Description
Technical field
The present invention relates to the luminescent characters that advertisement and identifier field is conventional, a kind of simple luminescent characters 3D Method of printing is efficiently provided especially.
Background technology
Luminescent characters adopts Light-Emitting Diode to be the Luminous character that light source makes, and the plurality of advantages such as it is attractive in appearance that it has daytime, and night is beautiful, and power and energy saving is durable in use, and the effect of publicity is good, are widely used in advertisement field.The preparation of current luminescent characters is still prepared as master by hand to adopt the equipment such as engraving machine, word bending machine and to combine, this kind of method all needs main equipment, the cooperation of space, place and degree of being skilled in technique just can complete making, not only efficiency is low, and can cause raw-material waste.
Along with the whole people innovate attacking of upsurge, 3D printing technique obtains the development of explosion type in manufacturing industry, industry, medical treatment, jewelry, space flight and individual application field, the development of 3D printing technique in ad production field needs to break through by the end of mainly containing two large bottlenecks at present, that is: print speed is slow and modeling is difficult.Existing three-dimensional model software and engraving software not general, and adopt the character and graphic of three-dimensional model software development can defectiveness, do not accommodate and carry out 3D printing.
Application number be 201310535075.5 patent document discloses a kind of method based on 3D printing and making stereo luminous character and device, the panel of the method first carve character contour, recycling 3 D-printing device along the surrounding edge material of face plate edge deposition stereo luminous character, and carries out milling process to surrounding edge outward flange; And then carve base plate, the holddown groove of carve character contour on base plate, and LED particle is arranged on base plate, finally the base plate being furnished with LED particle is installed on surrounding edge, completes the processing of whole stereo luminous character.The method there will be some problems in practical operation, and as the method utilizes 3 D-printing device along the surrounding edge material of face plate edge deposition stereo luminous character, but 3 D-printing device accurately cannot find face plate edge and along its marginal deposit surrounding edge material; And the surrounding edge existing defects printed, need to carry out milling process to it, not only increase cost of manufacture, and transparent surrounding edge cannot be made by this place, thus limit the pattern of luminescent characters; In addition, the method needs to carve holddown groove on base plate, and this not only needs to increase base plate thickness, and increases the time cost and cost of material that make luminescent characters further.
Summary of the invention
The object of the present invention is to provide a kind of 3D Method of printing of efficient, energy-conservation luminescent characters, the method is simple to operate, environment-friendly high-efficiency, and cost is low, and products obtained therefrom convenient later maintenance is applicable to applying.
The present invention specifically provides a kind of 3D Method of printing of luminescent characters, it is characterized in that, preparation technology's flow process is:
1., drawing modeling: design luminescent characters size, shape, make the font line frame graph with wall thickness;
2., luminescent characters panel is carved: adopt engraving machine according to step 1. gained font line frame graph making luminescent characters panel;
3., print wall and lamp plate: by step 1. gained font line frame graph be drawn into the word block diagram of three-dimensional band wall thickness, adopt 3D printing technique to print wall (surrounding edge) and lamp plate respectively; Wherein wall inwall is provided with the support edge perpendicular to wall, for support panel; The one side of lamp plate is provided with the fin perpendicular to lamp plate plane, and the distance at fin and lamp plate edge is the thickness of wall;
4., light source is pasted: light emitting source is affixed on the one side of lamp plate with fin;
5., assembling: wall is placed on outside the fin of lamp plate, then support panel being placed in wall is along upper, completes the assembling of luminescent characters.
The 3D Method of printing of luminescent characters of the present invention, it is characterized in that: step 1. in, wire-frame graphics is made after designing the size of luminescent characters, shape, this figure is imported in 3 d modeling software, lines in figure are broken into a large amount of point, then carry out line segment connection and round and smooth one-tenth circular arc, the point be broken into is connected into the lines of continuous and derivable, complete the reparation to font line frame graph defect; The line frame graph repaired is made the word block diagram of band wall thickness, store as panel carving line frame graph.
The 3D Method of printing of luminescent characters of the present invention, is characterized in that: when round and smooth one-tenth circular arc, points of tangency precision is set to 0.01mm, and circular arc tolerance value is set to 0.01 ~ 0.1mm.
By the word that input method of Chinese character inputs, existing defects under microcosmic condition, cannot be directly used in 3D and print, such as font lines have intersection, breakpoint, wedge angle, depression etc., if do not repaired, cannot complete modeling.In existing main flow 3 d modeling software; word just plays the booster actions such as mark and explanation; when word wire frame is as modeling basis; the mistake of slight part must be repaired; so the present invention is dispersed as a large amount of points word wire frame, then repair into level and smooth straight line or circular arc forms flawless word wire frame.
The 3D Method of printing of luminescent characters of the present invention, it is characterized in that: by step 1. in gained panel carving line frame graph be stored as the file of .dxf form, then open this file with Adobeillustrator software and change into the file of .eps form, finally open this file with civilian safe engraving software and change into .ac6 formatted file, thus deriving NC machining path.
The 3D Method of printing of luminescent characters of the present invention, is characterized in that: the distance at fin and lamp plate edge is the thickness+0.3mm fit clearance of wall; The fit clearance of panel carving is 0.22mm.The 3D Method of printing of luminescent characters of the present invention, it is characterized in that: the 3D printer head diameter that 3. step adopts is 0.4-0.8mm (preferred 0.6mm), wall thickness 0.4 ~ 1.6mm (preferred 1.6mm), thickness 0.2 ~ 0.6mm (preferred 0.6mm), temperature 200 ~ 260 DEG C (preferred 230-240 DEG C), hott bed 0 ~ 50 DEG C (preferably 50 DEG C), print speed is 40 ~ 80mm/min.The print quality of luminescent characters and print speed, thickness and nozzle diameter are inversely proportional to, and are directly proportional to nozzle temperature.Can the practical application request of printing opacity not exposure spot again by printing luminescent characters front and facade, its best configuration is: print speed 60mm, nozzle diameter 0.6mm, thickness 0.4mm, nozzle temperature 230-240 DEG C (slightly different with variation of ambient temperature).This is configured in and ensures that print quality improves 3-6 doubly with hourly velocity.
