Description
Technical field
The present invention relates to a kind of four bank or ridge unit cell configurations applied to 3D printing, specially a kind of point suitable for 3D printing
The basic microcellular structure used in battle array structure.
Background technology
Complicated microcellular structure is also generally referred to as lattice structure or porous structure, refers to by with grade is identical or phase
The material cell of nearly topology configuration connects a kind of spatial network shape being composed by orderly or unordered repeated arrangement mode
Structure.With the fast development of laser gain material manufacturing technology in recent years, the structure based on 3D printing moulding process is also more next
It is more ripe.The complicated microcellular structure for alloing some intensity, stiffness characteristics excellent is implanted into machinery knot by 3D printing technique
In structure part, construction weight is not only alleviated, the quality of structure is also improved.Generally, complicated microcellular structure is all close
Hexahedral unit cell form is right if the patent of Publication No. CN206536901U is a kind of typical hexahedron unit cell form
The shape fitness of part is poor, and especially the violent position of Curvature varying is difficult the light that outer surface is carried out by hexahedron unit cell
Sliding processing can only accumulate in surface district and adopt material, weight can be brought to increase.Further, since hexahedron structure, shape is connected from node
From formula, it is a unstable structure in stand under load, improves rigidity, still need to increase intermediate connection.So for outside some
Shape is complicated, and for needing the more part of light weight high rigidity, nearly hexahedral unit cell form can not fully meet demand.
Invention content
Insufficient to the fitness of the surface region of complex appearance for existing hexahedron unit cell configuration, the present invention provides a kind of
The unit cell configuration in complex appearance face can preferably be adapted to.
The technical solution that the present invention takes is a kind of four bank or ridge unit cell configuration applied to 3D printing, including connecting rod, branch
Strut and connected ball, connecting rod have 4, and every three connecting rod one end are connected by connected ball, four fringe truss structures of composition, and every two
It is connected by supporting rod in the middle part of a disjoint connecting rod.
Above-mentioned supporting rod intersection is connected by connected ball.
Above-mentioned connecting rod equal length.
Above-mentioned connecting rod is cylindrical or prismatic or hollow tubular.
The present invention has the advantages that and advantage：
The four bank or ridge unit cell configuration, geometric format is simple, and stiffness by itself is good, inside formed by supporting rod and connected ball
More Path of Force Transfer, the unit cell that the damage-resistant of structure can compare hexahedron configuration are more preferable.In addition, the length by connecting rod becomes
Change, is adapted to the unit cell filling of complex geometry shape, is very suitable for inside parts structure 3D printing, to reduce pts wt,
Improve the rigidity of structure.
Illustrate attached drawing
Fig. 1 is the basic unit cell stereoscopic schematic diagram for the four bank or ridge unit cell configuration that the present invention is applied to 3D printing；
Fig. 2 is processing schematic diagram of the four bank or ridge unit cell configuration on surface；
Fig. 3 is the schematic diagram that four bank or ridge unit cell configuration is applied to part.
Specific implementation mode
Invention is further described in detail with reference to the accompanying drawings of the specification.
A kind of four bank or ridge unit cell configuration applied to 3D printing, including connecting rod 1, supporting rod 3 and connected ball 2, connecting rod
There are 4, every three connecting rod one end are connected by connected ball, form four fringe truss structures, are the outer layer of unit cell, each two not phase
It is connected by supporting rod in the middle part of the connecting rod of friendship, is the internal layer of unit cell, as shown in Figure 1.
There are many forms for above-mentioned connecting rod 1, such as cylindrical, the forms such as prismatic or hollow tubular.
Above-mentioned supporting rod intersection is connected by connected ball.
It is positive four bank or ridge in the case of above-mentioned connecting rod equal length, if supporting rod is located at the midpoint of connecting rod,
It is intersected in a bit.
Embodiment illustrated in fig. 2 is the surface unit cell for changing out based on present invention proposition four bank or ridge cellular construction, be can be used for
Body structure surface structure 3D printing compares basic unit cell configuration, with superficial layer 5, in order to adapt to the fairing of superficial layer, to outer layer
Connected ball 2 has carried out shape adaptability and has cut to form outer layer connection hemisphere 6.
Embodiment illustrated in fig. 3 is that the present invention proposes four bank or ridge cellular construction by collectively forming a kind of typical dot matrix knot
Configuration formula, outside by surface unit cell permutation and combination, it is internal then pass through by 5 combined and spliced formation construction profile face 7 of superficial layer
The deformation shim part gap of basic unit cell configuration eventually forms internal dot matrix, external continuous overall structure.
There is the characteristic of good rigidity, shock resistance and light weight using the lattice structure of micro unit configuration design, in addition,
Due to tetrahedral configuration in entire unit, so have stronger adaptability to integrally-built shape, it is larger for some curvature
Overall structure, can easily fit construction profile by changing the edge angles of microcellular structure, while can also
The effective mechanical property for ensureing structure.
