Next layer is trained；
Step 5, is finely adjusted by the supervised training method of the multilayer neural network of standard；
Step 6, using the finished product print point actual position information obtained in real time as having exemplar and the degree of depth certainly
The short-term data of dynamic encoder model predictive system compares, if the result difference of comparison is big,
Just with there being exemplar to have the training of supervision to degree of depth autocoder model, adjust encoder
Network parameter, until predicting the outcome to fall at reasonable interval with finished product print point target position information difference be
Only, degree of depth autocoder training pattern is exported；
Step 7, trains mould according to real-time finished product print point actual position information by degree of depth autocoder
The error dot of type prediction 3D printer and mode error, adjust the run mode in current 3D printer
Gesture.
