Description

Method for automatically exporting AM model Technical Field The invention relates to the technical field of ships, in particular to a method for automatically exporting an AM model. Background AM, 3D printing, is a technique for manufacturing entities by stacking materials layer by layer, the core of which is a digital model (AM model). The AM model provides an efficient manufacturing means for the digitization to materialization of the ship model, and the CAD design file of the ship is imported through the special 3D printing software to perform model repair, light weight optimization, printing feasibility analysis and slicing processing, so that the ship model can be ensured to be printed in 3D. The two are related in that the ship model provides a design basis, and the AM model converts the design basis into manufacturable digital instructions, so that rapid prototyping verification, complex part production or old part repair can be performed. However, when the model is viewed using AM software in practice, the model viewing is relatively slow and the display area is limited due to the large amount of data. Especially when there are more elements contained in the model, the system can become stuck, affecting the user to view the model smoothly. Meanwhile, in order to view and call into the AM model, users often need to install AM environments, databases and associated project files on the computer, which is cumbersome and increases the use threshold and cost. With the improvement of the design complexity of ships, the data volume of the AM model is continuously increased, and the requirement on computer hardware is also higher and higher, so that AM software cannot be smoothly operated on some computers with lower configuration, and further the efficiency of model checking and operation is affected.

Further, in the step S1, color rules of the export model are set by configuring objects files, so as to ensure that color information is contained when the export model is exported, and the specific operation is that a file with a suffix of pmlobj in a folder is placed in a configuration file address under an AM installation directory. Further, the file with suffix of pmlobj in the folder is kNWFilesGenColobj, NWFilesGenColobj, NWFilesGenSettobj. In step S1, a plurality of calculation functions are designed for window program call to realize specific functions such as model derivation by configuring functions files, and the specific operation is that a file with a suffix of pmlfun in a folder is placed in a configuration file address under an AM installation directory. Further, files with suffix of pmlfun in the folder are NWFILESGenExp.pmlfnc, NWFILESGenExport.pmlfnc, xpCoordTransnew.pmlfnc. Further, in step S1, a program operation interface is generated by configuring forms files for the user to interact with the software, and the file with the suffix of pmlfrm in the folder is placed in the configuration file address under the AM installation directory. Further, the file with suffix of pmlfrm in the folder is nav.pmlfrm. Further, the specific operation of step S2 is to re-open the AM arbitrary structure interface after closing all the running AM programs, and input PMLREHASHALL in the command box to load the newly configured plug-in.
