Provided are a three-dimensional object inkjet printing method, a printing apparatus and a computer-readable storage medium. Where the three-dimensional object inkjet printing method includes: forming an adhesion support portion () on a support platform () first, and then forming an elastic support portion () on the adhesion support portion, the elastic support portion being embedded with a first elastic portion (), and finally, forming a target object () by printing layer by layer on the elastic support portion. Therefore, a possibility of affecting a printing precision due to a separation of a material layer and the support platform is reduced, and a possibility of cracking in a bottom of the support when subjected to an impact force during an inkjet printing process is reduced at the same time, and a printing reliability is improved.

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.

3D printing method and device

An illustrative example support structure includes a solid portion printed using a first material and a non-solid portion printed using a second material. The solid portion includes a grid structure, and both inside and outside of each grid unit of the grid structure are filled with the non-solid portion. Hardness of the first material is different from hardness of the second material. A grid density of the grid structure varies within a printing plane, and/or an area of a cross-section of a connecting edge of the grid unit varies in a direction perpendicular to the printing plane. There are differences in strength of different portions of the support structure of the present disclosure, so that an adverse effect of cracking of the support structure caused by a stress concentration phenomenon occurring when the support structure is subjected to a stress during or after a curing process can be effectively prevented.

The method includes for a model placed on a specified plane, determining at least one reference plane in a direction parallel to the specified plane. The method also includes for the at least one reference plane, obtaining at least one vertical projection area by acquiring a vertical projection area of the model above each reference plane projected on a corresponding reference plane. Further, the method includes according to the at least one vertical projection area, obtaining a total volume; and according to the total volume and a volume of the model, obtaining the volume of the supporting structure of the model.

Method and device for acquiring volume of structure, non-transitory computer-readable storage medium and printer

An image data processing method and a printing system for printing technology are provided. The image includes a first bitmap image. The image data processing method includes: dividing the first bitmap image into a plurality of regions, selecting sampling positions in each of the plurality of regions, performing sampling to acquire sample points, and rearranging the sample points to form a second bitmap image. The second bitmap image is different from the first bitmap image.

Image data processing method and printing system for printing technology

Method and apparatus for full color data processing for 3D objects are provided. The method includes: performing a layering process on a target object to determine slice-layer data of each layer, wherein the slice-layer data includes layer-color data and layer-structure data, the layer-color data represents color information of the target object, and the layer-structure data represents a printing location of the target object; and analyzing the layer-color data and the layer-structure data when the layer-color data is consistent with background color data of the target object and analyzing the layer-color data when the layer-color data is inconsistent with the background color data of the target object, thereby determining a layer color of the target object and determining printing information of the target object.
