Method.
Background technique
In recent years, the data volume rapid development that the mankind generate, therefore the demand to memory is also growing, and existing deposits
Reservoir, either tape, hard disk flash memory are typically all two-dimensional structure, although there is 3D flash technology in flash memory in recent years,
But its stackable number of plies in the third dimension is limited, therefore third dimension space can not be made full use of.In addition, existing difference is deposited
Storage media does not grow the holding time of data generally.
3D printing technique, also known as increasing material manufacturing, lamination manufacture, grow up in the 1980s.1981, small Yu Xiu
The method that male has invented two kinds of increasing material manufacturing three-dimensional plastic models using photocured polymer, Chuck Hull invention in 1984
Stereolithography solidifies high molecular polymer with ultraviolet laser, layer of feed stock material is gathered into folds.It much can be with currently, having had

Specific embodiment
In order to which technical solution disclosed by the invention is described in detail, with reference to the accompanying drawings of the specification and specific embodiment is done
It is further elucidated above.
The flow chart proposed by the present invention that data storage and reading are carried out based on 3D printing technique and CT technology, such as Fig. 1 institute
Show.It is specific the following steps are included:
Step 1: binary data is converted to STL by program after data carry out source coding and channel coding by coding
File, the stl file describe the 3-D graphic that 3D printer can read and smoothly print.Conversion regime is as follows:
This example uses micro-nano 3D printer nanoArchS140, and required 3-D graphic is each layer of three-dimension object
Plan view, successively printing resolidification is carried out according to each layer of planar graph.
Therefore 3D printer can be enabled to print one using storing data whether the minimum precision point printing that each layer can print
Minimum precision point as binary data 1, without printing this minimum precision point 0 as binary data.For
3D printer printing principle (see step 2), following figure transformation rule can be used:
Using one 4 × 4 (a) totally 16 minimum precision o'clock, as a minimum unit, (minimum accurate values depend on 3D
The parameter of printer), as shown in Figure 2:
Wherein, the first row and first row totally seven minimum precision points, are indicated, all 3D printers are needed with black squares
The minimum precision point to be printed, in this, as the frame of this sample, it is clear that these minimum precision points are to interconnect, can be with
One stable structure is provided.
Totally six minimum precision points are used to store a segment length as 6 ratios for second row and latter three minimum precision points of fourth line
Special two-stage system number, wherein if some binary number is 1, corresponding minimum precision point will be printed, if
Some binary number is 0, then corresponding minimum precision point will be not printed out.Obviously, these minimum precision are such as
It also must be to be connected with above-mentioned frame, therefore sample can be a stable structure that fruit, which is printed,.
The minimum precision point of latter three of the third line, is indicated, all 3D printers do not need to print with white square
The minimum precision point come can guarantee to input any binary data in this way, the sample printed does not have confined space,
Liquid resin can flow out, and can smoothly obtain sample as memory.
According to the figure transformation rule of appeal, writes and the binary data stored will be needed to be converted to accordingly using program
Stl file, which, which describes, needs the binary data that stores to pass through the three-dimensional figure that above-mentioned figure conversion regime obtains
Shape.
It is the signal that one section of binary data is converted to a 3-D graphic according to above-mentioned figure transformation rule such as Fig. 3
Figure.
Step 2:3D printing, send stl file obtained in step 1 to 3D printer, by individual print as
Store the memory of former binary data.
Detailed process is as follows for 3D printing: firstly, loading to the single picture of the stl file description of input, then
It is exposed one by one, ultraviolet lighting is mapped to liquid photosensitive resin surface, makes one layer in the surface specific region on molding flat
Resin solidification, as soon as a section of part is generated after layer completion of processing；Then, print platform Z axis declines certain distance,
Resin storage tank Z axis, which first rises, simultaneously declines certain distance afterwards and makes the liquid level after the good levelling of liquid level and holding levelling to new cured layer
Certain layer is high.Another layer of liquid resin is covered on cured layer, then carries out second layer scanning, before the second cured layer is bonded in securely
On one cured layer, it is formed by stacking 3 D workpiece prototype from level to level in this way, finally, carrying out final by prototype after taking out in resin
Solidification, so that it may obtain storing the individual (memory) of data.
Step 3: it saves, the individual printed is placed in suitable environment, compare existing memory, what the present invention obtained
Sample has longer data retention over time.
Step 4:CT scanning can be used technical grade CT and carry out to it if the data that memory stores read out
Scanning: being irradiated sample using X-ray, and digital detector receives the X-ray by decaying after object, then sample is done small
The rotation of angle, repeats the above process, by the x-ray bombardment and reception of limited times, it can be deduced that the space structure of memory.
Step 5: decoding, after the space structure that memory is obtained by step 4, by being converted with the figure used when coding
The dedicated graphics algorithm that mode matches is reduced to binary data.
All steps can be indicated such as Fig. 4.
The present invention can make full use of three-dimensional space, and mass data is stored in certain volume, to the holding time of data
Longer, the storage cost of unit data quantity also will be lower.The precision for the 3D printer that this example uses is 40 μ m, 40 μ m, 20 μ
M can store the information of about 1.5Gb in the space 72mm × 40mm × 45mm, but being not meant to can only be using this
3D printer can only store these data in unit volume.
It should be understood that above-mentioned machine used in this example is intended merely to facilitate the reading for illustrating hardware structure and memory
Write process, non-is the read-write process and storage capacity for limiting this storage method, can be with using more advanced 3D printer and CT
The storage capacity of this storage method is improved more significantly, and the printing principle of current high-precision 3D printer is similar, therefore this
The figure conversion method mentioned in invention is indispensable.
