Description
Technical field
The present invention designs a kind of parallel slice systems of 3 D-printing, can quickly cut to a large amount of threedimensional model files
Piece.
Background technique
With the continuous development of information technology, hardware cost is constantly reduced, parallel computation using more and more extensive.The skill
The appearance of art has driven many development with the closely related industry of computational science.3D printing technique is in the 1990s
A kind of newest rapid shaping technique that phase occurs, significance can be compared with Numeric Control Technology.The technology is with mathematical model
Based on file, with adhesive materials such as powdery metal or plastics, the skill of object is constructed by layer-by-layer printing
Art.
3D printing technique generates the control path of printer using Slice Software based on digital model file, above-mentioned
Process is entirely digitized process.3D printing technique will not select different machines because of model difference again in process of production
Device.As long as the change of software view is all pertained only to regardless of producing any model, with biography after therefore printed material and printer determine
The numerical control production method of system is compared, and the digitized degree of 3D printing technique is significantly improved.Traditional manufacture needs
A series of processing technology, and 3D printing technique only needs to use an equipment and can complete to process.The digitlization of 3D printing
Manufacture characteristic and parallel computation have it is technical link, using parallel computing, can largely improve 3D printing
Efficiency.In view of after 3D printer is universal, it may appear that the case where needs are sliced a large amount of model files appearance.It presses
According to traditional dicing method, model slice can only carry out on a machine, low efficiency and be unable to fully using computing resource.
It and is also a more complicated process for the planning of the printing batch of a large amount of model files.In model file number
Measure it is less in the case where, manual alignment can also meet the needs of production.Face a large amount of model files in the case where, manually into
The efficiency of row model arrangement is relatively low, and rank results are not necessarily optimal solution.
Based on above-mentioned consideration, is combined using three-dimensional printing technology, model permutation technology with parallel computing, sufficiently mentioned
High 3 D-printing model slice efficiency proposes a kind of parallel model slice systems.
Summary of the invention
The present invention combines model permutation technology, 3 D-printing model slice technology with parallel computing, realizes fast
Speed arranges a large amount of models, is sliced.
The technical solution adopted by the present invention is a kind of parallel 3 D-printing slice systems using model Nesting Algorithms, this is
System includes two cores, and one is model arranging system, and one is model slice system.
Model arranging system include model treatment part and Rectangle flap portion in two sub-sections.Model treatment part and calculating
Machine connection, model needed for the 3 D-printing stored in computer is read in model treatment part first later will be needed for 3 D-printing
Model projection finally seeks the least surrounding boxes of 3 D-printing model projection to xoy plane using rotary process.Obtain three-dimensional beat
After the least surrounding boxes for printing model projection, Rectangle flap part is started to work.It is arranged using existing rectangle Rectangle flap part
Sample algorithm arranges the least surrounding boxes of threedimensional model projection, and the rank results of threedimensional model guarantee：1) each batch
Printout be no more than the print size of printer；2) it is not overlapped between printout；3) always printing batch is minimum.It has arranged
Cheng Hou rotates master mould according to rank results, and by all Model Reconstructions in same batch at a new impression block
Type, until each batch all corresponds to a new printer model.All new printer models are sent to model slice system.
Model slice system is divided into a host and multiple extension sets.Host is responsible for receiving the new printer model that arrangement is completed,
Extension set state is managed, the gcode file generated after the completion of extension set slice is received, according to receiving the quantity of new printer model to model
It is grouped, number of packet is consistent with idle extension set quantity.Extension set is responsible for the model file of receiving host transmission, using now
Some Slice Softwares are sliced model file, and the gcode that slice generates is transferred to host.
Existing model slice system is improved using above system, magnanimity threedimensional model is quickly cut in realization
Piece.
Technical characterstic of the invention：
1, printout is projected, and obtains the least surrounding boxes of projection.
2, stock layout is carried out to the projection of model using Rectangle flap algorithm, obtains printing batch.
3, the model of same printing batch is reconfigured to the threedimensional model of new slice.
4, host is grouped the slice received with threedimensional model.
5, more extension sets are simultaneously sliced model.
6, gcode file is transferred to host after the completion of extension set slice.
Detailed description of the invention
Fig. 1 is model aligning part schematic diagram.
Fig. 2 is parallel sliced section schematic diagram.
In figure：1. 2. model arrangement computer system of a large amount of threedimensional models, the 3. slice model 4. for needing to be sliced is parallel
The parallel slice systems extension set of 5. model group of slice systems host 6.
Specific embodiment
It is necessarily pointed out that the present embodiment is served only for, invention is further explained first, should not be understood as
Limiting the scope of the invention.
