Abstract
The invention provides a multi-faced type three-dimensional printing method. A polyhedron is cast by a mold and three-dimensional printing is carried out on each face of the polyhedron to form a workpiece. The multi-faced type three-dimensional printing method particularly comprises the following steps: establishing a workpiece model; analyzing and calculating the workpiece model and an internally-connected polyhedron model, wherein the polyhedron model has N sides and N is more than or equal to 5; obtaining N printing models which take planes of all the sides of the internally-connected polyhedron model as bottom surfaces according to the workpiece model and the internally-connected polyhedron model; combining all the printing models with the internally-connected polyhedron model to form the workpiece model; cutting each printing model into layers to obtain a layered pattern; generating a mold according to the internally-connected polyhedron model and generating the internally-connected polyhedron model by the mold; and printing the corresponding models by taking the planes of all the sides of the internally-connected polyhedron model as the bottom surfaces according to the layered patterns. According to the multi-faced type three-dimensional printing method provided by the invention, the production efficiency is improved by using a three-dimensional printing technology.
Description
Technical field
The present invention relates to three-dimensional printing technology field, particularly relate to a kind of multiaspect formula 3 D-printing method.
Background technology
3 D-printing also claims 3D to print (Three Dimensions Printing), belongs to the one of RP technique.It is a kind of based on mathematical model file, uses powdery metal or plastics etc. can jointing material, is carried out the technology of constructed object by the mode successively printed.Past, its field such as Making mold, industrial design of being everlasting was used to modeling, now just gradually for the direct manufacture of some products, particularly some high-value products (such as hip joint or tooth, or airplane component) have had the parts using this technology to print.3 D-printing normally adopts digital technology file printing machine to realize, because three-dimensional printing technology is comparatively complicated, so length consuming time, efficiency are low, high in cost of production problem to utilize the production technology of three-dimensional printing technology to exist.
Summary of the invention
Based on the technical problem that background technology exists, the present invention proposes a kind of multiaspect formula 3 D-printing method, be conducive to improving the production efficiency utilizing three-dimensional printing technology.
A kind of multiaspect formula 3 D-printing method that the present invention proposes, by die casting polyhedron, and carry out 3 D-printing with each face polyhedral for bottom surface and complete workpiece, specifically comprise the following steps:
Set up part model;
Analytical calculation part model inpolyhedron model, polyhedral model has N number of, N >=5;
According to part model and inpolyhedron model, obtain N number of respectively within to connect each place, face plane of polyhedral model be the printer model of bottom surface, all printer models and inpolyhedron model group synthesis part model;
Slice by slice cutting is carried out to each printer model, obtains hierarchical diagram;
According to inpolyhedron model production mould, and by mould production inpolyhedron;
According to hierarchical diagram, with each place, face plane of inpolyhedron for bottom surface prints corresponding printer model.
Preferably, N=6.
Preferably, inpolyhedron model is inscribed within part model.
Preferably, each printer model bottom surface overlaps with corresponding inpolyhedron model surface.
Multiaspect formula 3 D-printing method provided by the invention, inside workpiece is carried out shaping the separating with surface of the work, inside workpiece is produced in batches by punch die, high efficiency high-quality, and outside is printed by three-dimensional printing technology, ensure that the quality that workpiece body surface prints and surface of the work precision.
In this method, the inside workpiece structure of being produced by punch die is polyhedron, thus ensure that when carrying out body surface three-dimensional printing to workpiece, prints the smooth of bottom surface, reduces three-dimensional printing difficulty.
The application of this method can carry out printing speed by the workpiece high to some surface finish requirements.
When this method is specifically implemented, inpolyhedron model is inscribed within part model, so, can increase the inside filling part that workpiece is produced by punch die as far as possible, to reduce three-dimensional printing workload, thus enhance productivity further.
Accompanying drawing explanation
Fig. 1 is a kind of multiaspect formula 3 D-printing method flow diagram that the present invention proposes.
Detailed description of the invention
With reference to Fig. 1, a kind of multiaspect formula 3 D-printing method that the present invention proposes, by die casting polyhedron, and carries out 3 D-printing with each face polyhedral for bottom surface and completes workpiece.
The method specifically comprises the following steps:
S1, set up part model.
S2, analytical calculation part model inpolyhedron model, polyhedral model has N number of, N >=5.
In present embodiment, get N=6, the preferred cube structure of the inpolyhedron namely obtained, so that following process.
S3, according to part model and inpolyhedron model, obtain N number of respectively within to connect each place, face plane of polyhedral model be the printer model of bottom surface, all printer models and inpolyhedron model group synthesis part model.
S4, Slice by slice cutting is carried out to each printer model, obtain hierarchical diagram.
S5, according to inpolyhedron model production mould, and by mould production inpolyhedron.
Can be mass inpolyhedron by module, not only can enhance productivity, and can ensure that the quality of inpolyhedron is harmonious.
S6, according to hierarchical diagram, with each place, face plane of inpolyhedron for bottom surface prints corresponding printer model.
In this method, carried out shaping the separating with surface of the work by inside workpiece, inside workpiece is produced in batches by punch die, high efficiency high-quality, and outside is printed by three-dimensional printing technology, ensure that the quality that workpiece body surface prints and surface of the work precision.The application of this method can carry out printing speed by the workpiece high to some surface finish requirements.
When this method is specifically implemented, in step S2, inpolyhedron model is inscribed within part model, so, can increase the inside filling part that workpiece is produced by punch die as far as possible, to reduce three-dimensional printing workload, thus enhance productivity further.
When this method is specifically implemented, in step S3, each printer model bottom surface overlaps with corresponding inpolyhedron model surface, to reduce amount of calculation, improves operation efficiency.
The above; be only the present invention's preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
