Information collection, and n is integer more than 2；And n=N, i.e. the number of plies and line number is corresponding, and slice width and line width are corresponding.
Step S32, host computer choose the respective layer with demarcation row as Primary layer, X will be defined as in addition to Primary layer
Layer, and preliminary design X is 1；
Step S33, compare the discrepancy of X layer and Primary layer, and the coordinate position of discrepancy is marked by coordinate system；Wherein
Discrepancy more than Primary layer is marked before coordinate with "+", and the discrepancy fewer than Primary layer is marked before coordinate with "-",
After forming the additional information collection of X layer, X=X+1 is performed, until forming additional information collection of each layer relative to Primary layer；Specifically
Determination methods include：Compare whether X is more than n, be then to enter step S34, otherwise return to repeat step S33.
Using the difference of Primary layer and other layers and Primary layer, so that the data after processing are less, therefore contract significantly
Short host computer was transmitted to the time of 3D printer, meanwhile, 3D printer is when reading above-mentioned data, it is only necessary to reads a base
This layer of information, then it is successively read the additional information collection of equivalent layer, you can the type information of this complete layer of composition, therefore shorten
The read access time of information, therefore, operating efficiency is higher.
The host computer is about to be transferred to the method for 3D printer after model decomposition to be printed also including following according to demarcation
Step：
Step S34, host computer transmit Primary layer information and additional information collection to 3D printer, by the printing number of plies of 3D printer
It is defined as Y；The initial value for setting Y is 1；And
Step S35,3D printer print Y layer models on the table according to Primary layer information and additional information collection control shower nozzle
After material object, Y=Y+1 is performed, until all layers of end of transmission；Specific determination methods include：Compare whether Y is more than n, be to sentence
Disconnected printing terminates, and otherwise returns to repeat step S35.
Also, the host computer will be transferred to 3D printer after model decomposition to be printed can also include step S36, i.e. institute
Stating host computer and 3D printer will be transmitted to 3D printing again by network connection, the host computer after the compressing file after decomposition
Machine；And decompressed after 3D printer reception compressed file.The host computer will be transmitted again after the compressing file after decomposition to
3D printer.Therefore the file of transmission is further reduced, and the speed locally decompressed is much larger than the speed of network transmission, therefore
Overall, the time-write interval has been saved.
The internetwork connection mode can use bluetooth, WiFi or RJ45 interfaces to be attached.
