Abstract
A layered modeling method for laser metal deposition (LIVID) 3D printing. The layered modeling method includes: obtaining estimated printing parameters of each layer in an entire digital model based on a process database; obtaining estimated feature points of each layer through the estimated parameters; comparing estimated feature points of each layer with feature points of a corresponding actual shape to obtain a difference in each layer; and accumulating to obtain a difference in the entire digital model to obtain corresponding printing parameters. The layered modeling method has the advantages of effectively reducing the calculation amount during data comparison and greatly saving time.
