Abstract
A kind of 3D printing method, device and equipment is provided, can be improved 3D printing modeling and printing effect.This method comprises: obtaining using square as the object model of basic unit, the big small cubes such as square is will be converted into 3D printing file by the object model of basic unit of square, 3D printing file be sent to 3D printer and is printed.The 3D object model is using square as basic unit, because square is the particle for having volume, be equivalent to printing during 3D printing is with square for basic 3D pixel, by 3D model conversion in 3D printing file processes without the concern for "current" model if appropriate for 3D printing, therefore, the 3D printing method can save the calculation amount in 3D printing file calculating process, so as to improve the efficiency of 3D printing, improve printing success rate.
Description
The present invention relates to field of computer technology more particularly to a kind of 3D printing method, device and equipments.
3D printing is one kind based on digital model file, with adhesive materials such as powdery metal or plastics, constructs the technology of object by layer-by-layer printing.
The design process of the 3D printing of the prior art is: first passing through computer software, then the threedimensional model built up is divided into layer-by-layer section, that is, be sliced, so that printer be instructed successively to print.Printer is printed in these sections with liquid, powdery or the material of sheet, then each layer cross section is glued together in various ways to produce an entity layer by layer by reading the cross sectional information in file.
3D method in the prior art is to be carried out based on point, line, surface using traditional CAD software such as Maya, 3dsmax.When 3D printing, due to being influenced by terrestrial gravitation, not all 3D model can be carried out 3D printing, need to guarantee that model can not collapse in print procedure, and each moment is taken into account enough, therefore the person of needs just decides how to go 3D printing in configuration, is otherwise hardly produced suitably printable file.For the above process in addition to algorithm complexity, time-consuming is outer, often human eye is finally also needed to check one time, causes and printing effect is relatively low.
Summary of the invention
The present invention provides a kind of 3D printing method, device and equipments, can be improved the efficiency of 3D and printing.
First aspect of the embodiment of the present invention provides a kind of 3D printing method, comprising:
