  • Publication number: 20210252790
    Abstract: A color 3D printing method, a printing apparatus and a terminal device. The printing method includes acquiring an original three-dimensional model of an object to be printed; performing shell processing to the original three-dimensional model to generate an inner model and an outer model of the original three-dimensional model; performing slicing processing to the inner model and the outer model to generate multiple printing data corresponding one-to-one with each printing layer, the printing data including structural data representing the inner model in a printing layer, color data representing the outer model in the printing layer, and structural data representing the outer model in the printing layer; printing the object to be printed according to the printing data. The present method can distinguish between a background color and a surface color of the original three-dimensional model in a slice image, avoiding phenomena of not printing or misprinting.

  • Publication number: 20200290286
    Abstract: A printing method and a printing device are provided. The printing method includes: determining, according to layer printing data of an object to be printed, a trip starting point and/or a trip ending point in a scanning direction for each trip of multiple trips required for a print head to print a preset layer, where the trip starting point and/or a trip ending point of at least one trip matches a contour of the object to be printed in the trip (S101); and performing layer printing for the preset layer according to the trips (S102).

  • Publication number: 20200061928
    Abstract: The disclosure provides a 3D printing method and device. The 3D printing method of the disclosure includes: obtaining height groups of an object to be printed in multiple different postures relative to a support platform, where different height groups include a height of the object to be printed in at least one direction corresponding to the different postures; obtaining a first height having a minimum height from all of the height groups, and obtaining a second height and a third height orthogonal to the first height according to the first height, where the second height and the third height are minimum heights in their respective directions; and taking directions in which the first height, the second height, and the third height are located as three printing directions of the object to be printed respectively, and printing. The disclosure can achieve a fast printing speed.
