Title:
THREE-DIMENSIONAL OBJECT PRINTING METHOD, DATA PROCESSING APPARATUS, AND COMPUTER DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/040290
Kind Code:
A1
Abstract:
The present application provides a three-dimensional object printing method, a data processing apparatus, and a computer device. The method comprises: acquiring a three-dimensional digital model of an object to be printed, and obtaining multiple slice layers; making multiple parallel lines along a stacking direction of the slice layers to acquire an intersection point sequence; determining a transition point in the intersection point sequence, a transition point being an intersection point between an nth slice layer and an (n +1)th slice layer of the three-dimensional digital model; determining a transition region and a non-transition region in the nth slice layer according to the transition point; determining to print the non-transition area using a first printing mode, and determining to print the transition area using a second printing mode, a second physical ink quantity per unit volume injected in the second printing mode being lower than a first physical ink quantity injected per unit volume in the first printing mode; generating layer print data of the object to be printed for printing. The three-dimensional object printing method provided by the present application can improve the problem of surface layer patterns on an object, thereby improving surface precision of a three-dimensional printed object.
