When specific implementation, after the single-layer model information for receiving the output of printing equipment processor, in the biography of gear synchronous band
Under dynamic, control rotating knife is precisely cut according to profile information, and rotating knife cutting mode can improve common cutter head cutting not
Thoroughly, and the gap that leaves is advantageous to the dismounting of later period waste material and consumes energy low also because it is not required to heat, pollution-free, excellent
In laser probe.
Step S103 controls above-mentioned rotating knife in dielectric layer to be removed and cuts out dismounting auxiliary line, to remove Jie to be removed
The waste material of matter layer.
In order to facilitate later period dismounting, on the dielectric layer to be removed of cut graph outline, dismounting auxiliary line is cut out.
In inventive embodiments, cuts platform and dielectric layer is cut using rotating knife, the gap after increasing cutting,
Be conducive to the dismounting of waste material after model forming, and be effectively relieved due to when cutter head reciprocatingly slides occasional destroy needed for part,
The problem of reducing model accuracy, resulting even in the damage of entire model.
After the completion of cutting in view of the graph outline of every layer of dielectric layer, cutting for auxiliary line is very important, otherwise mould
It can not be taken out after the completion of type printing.In order to facilitate later period dismounting, traditional method is in required graph outline external parallel in paper
Zhang Bianyuan is cut into vertical and horizontal straight line according to the size of figure, redundance is divided into bulk, the later period is facilitated to remove.But every layer of cutting
Process needs are cut more than ten times on whole breadth, considerably increase the print time.It is above-mentioned in dielectric layer to be removed based on this
The dismounting auxiliary line cut is the divergence expression that the edge of dielectric layer is extended to from the outer edge of the graph outline of dielectric layer to be removed
Lines.
Wherein the quantity of the divergence expression lines is determined according to the complexity of model to be printed.For example, see Fig. 2, when to
When the complexity of printer model is low, i.e., globality is high, no minor detail, the little model of the graph outline difference of each layer, choosing
Auxiliary line is removed with four bases；When the complexity of model to be printed is middle, i.e., each layer profile difference is larger, there is local detail
Model, select eight divergence expression lines cutting methods, i.e., increase on the basis of auxiliary line is removed on four bases four it is additional
Remove auxiliary line；When the complexity of model to be printed is high, hollow out, when poroid equal labyrinths are more, for labyrinth
Part increases partial dismantling auxiliary line.It should be noted that removing auxiliary line sum is no more than default value, such as 16.
The complexity of above-mentioned model to be printed is determined according to the cutting line quantity and number of grid of model to be printed.
Assuming that the grade of model complexity to be printed is divided into basic, normal, high three grades.Referring to Fig. 3, computer establish to
After printer model, which is all made of triangle or quadrilateral mesh, and the grid the more, represent complexity
It is higher.After having established model to be printed, the quantity of the cutting line in model to be printed can be detected automatically, which can be with
It is specified by related personnel, the top view such as Fig. 4 of the model after cutting (are only to be not intended as limiting by taking 8 cutting lines as an example in Fig. 4

When value, determine that the complexity of model to be printed is low.Wherein the default Low threshold can be in each modeling, self-defining,
It can choose system default value, which can be 8,9,10 etc..
When the cutting line quantity of model to be printed is more than or equal to default Low threshold, can detect automatically by adjacent cutting line structure
At the number of grid of each partitioning portion (8 partitioning portions in referring to fig. 4) (such as 3Ds Max software can be read directly
Number of grid), determine the number networks.The complexity of the bigger partitioning portion of number of grid is higher, when the number networks be respectively less than etc.
When preset threshold, determine that the complexity of model to be printed is；When the number networks are greater than preset threshold, mould to be printed is determined
The complexity of type is height, increases in the part and removes auxiliary line, that is, partial dismantling auxiliary line.It is more than namely default in cutting line
When Low threshold, the density for removing auxiliary line is related to the number networks.
It should be noted that the complexity of above-mentioned model to be printed can be the computer analysis by connecting with printing equipment

Layer, and next layer of dielectric layer is transmitted at once after the completion of this layer is cut and cuts platform, thus can uninterruptedly it cut, and
Eliminate the front-end print time.Based on this, in a further embodiment, before step S102 further include: it is next to send printing
Layer is instructed to the print platform of 3D printing device, so that the print platform prints next layer of dielectric layer.Correspondingly, in step S102
Later further include: the transmitting device for sending send instructions to 3D printing device, so that the transmitting device passes next layer of dielectric layer
Transport to the cropped area for cutting platform.

In specific implementation, can include in the upper left corner or other specified region printings when every layer of dielectric layer prints
This page be which layer information graphic code such as bar code or two dimensional code, cut platform install additional figure code recognition device, to the figure
Shape code is identified to obtain the layered identification, the layered identification and the layered identification of the preceding dielectric layer once cut is compared, really
Whether the sequence of the dielectric layer printed before settled is chaotic, and warning note can be carried out when causing confusion, to avoid the number of plies mixed
Random wrongly typed problem.
Control in order to be more accurate cuts the accuracy of image outline, the above method further include: obtains inductive pick-up
The cutting track of collected rotating knife.Specifically, this cuts platform and is also connected with inductive pick-up, which can be with
But it is not limited to infrared sensor；The inductive pick-up can incude the cutting track of rotating knife, and the cutting track is sent
To cutting platform.
Above-mentioned steps S102 includes: to adjust the rotating knife for cutting platform according to above-mentioned profile information and above-mentioned cutting track
Moving direction, to be cut to obtain dielectric layer to be removed to corresponding dielectric layer.I.e. by profile information and cutting track into
Row comparison, if it is determined that offset distance is greater than pre-determined distance, then adjusts the moving direction for cutting the rotating knife of platform, inclined to reduce
Distance is moved, the accuracy cut is improved.
After the completion of cutting, white glue with vinyl is coated using idler wheel in graph outline part and scrap area part in Fig. 2 respectively
Or directly using hot melt gummed paper, the dielectric layer cut is needed to be dragged to this layer of top next layer, rise cuts platform, presses upper
In the heating plate of side, the bonding of layer and interlayer is carried out.Repetition cuts process and adhesion process, until the printing of each layer is completed.
After the completion of printing, from the dielectric layer cut after taking out bonding on platform.Remove cropped area (referring to fig. 2) outside first
