Description
Technical field
The invention belongs to 3D printing technique fields, and in particular to a kind of one-way heat conduction film and its in 3D printer heating plate
On application.
Background technique
3D printing (3DP) i.e. one kind of rapid shaping technique, it is a kind of basic for printing with digital model file, utilization
The adhesive materials such as powdery metal, plastics or clay construct the technology of object by layer-by-layer printing.
3D printing is usually that digital technology file printing machine is used to realize.Often led in mold manufacture, industrial design etc.
Domain is used for modeling, after be gradually available for the direct manufactures of some products, had using zero made of the printing of this technology
Component.The technology is in jewelry, footwear, industrial design, building, engineering and construction (AEC), automobile, aerospace, dentistry and medical treatment
Industry, education, GIS-Geographic Information System, civil engineering, gun and other field are all applied.
3D printing technique was employed for building field in recent years, to realize low cost, for the purpose of being quickly manufactured.And stone
The 3D printing of cream base becomes hot subject.
It is heating and curing as the common curing method of existing 3D printer, the heating bottom plate pair being arranged by 3D printer bottom
The printed products such as gypsum slurry are heating and curing, and heat and are additionally provided with thermally conductive film (generally between bottom plate and printed product
Glass material), for conducting heat, cause heat conduction efficiency during thermal-curable 3D printing low, heat is not concentrated, and is produced
The defects such as product solidification is uneven and printing precision is low.
The purpose of the present invention is to the shortcomings of building field 3D printing technique gypsum base printing to provide a kind of list
To thermally conductive film, especially suitable for thermal-curable 3D printing device, during can solve gypsum slurry thermal-curable 3D printing
The problems such as heat conduction efficiency of appearance is low, and heat is not concentrated, and solidification is uneven and printing precision is low.
Summary of the invention
The technical problem to be solved by the present invention is to aiming at the above shortcomings existing in the prior art, provide one kind unidirectionally to lead
Hot film and its application in 3D printer heating plate.
In order to solve the above technical problems, present invention provide the technical scheme that
A kind of one-way heat conduction film is provided, the one-way heat conduction film fits closely group by multiple columnar fiber units side by side
At each columnar fiber unit is made of the column heat carrier of the heat insulator of cannulated and filling in the inner.
According to the above scheme, the column heat carrier material is graphite or carbon nanotube, column heat carrier cross section be it is round,
One kind of square, regular hexagon and other regular polygons.Graphite or carbon nanotube are coaxially extruded into columnar fiber beam, when
When the content of graphite or carbon nanotube in columnar fiber beam reaches percolation threshold, effect that heat is conducted along fiber caliber direction
Rate is much larger than perpendicular to the conduction efficiency on caliber direction, to realize one-way heat conduction.
According to the above scheme, the circumscribed circle diameter of column heat carrier cross section is 0.1~0.5mm.
According to the above scheme, the heat insulator is polyethylene.
Preferably, the heat insulator pipe thickness is 0.1mm.
According to the above scheme, the one-way heat conduction film thickness is 1~10mm.
The present invention also provides application of the above-mentioned one-way heat conduction film in 3D printer heating plate, specifically used methods are as follows:
One layer of one-way heat conduction film is set between 3D printer heating plate and 3D printing product.When heating laser beam shines one-way heat conduction
When above film, heat is gathered in columnar fiber unit one end, due to inside columnar fiber unit graphite or carbon nanotube
Reached percolation threshold, can be realized one-way heat conduction, therefore can be by the heat of one-way heat conduction film one end along columnar fiber unit
Inside is transmitted to the other end.
Contain moisture in gypsum slurry, laser beam shines directly into gypsum slurry surface and can dissipate during 3D printing
It penetrates, heat is caused not concentrate, heat transference efficiency is low.Columnar fiber unit outer wall of the present invention selects polythene material to be made, poly- second
Alkene material has good heat preservation and insulation, and heat is avoided to transmit in each columnar fiber unit, guarantees the list of heat conduction
Tropism, while polythene material is again easy to process, it is at low cost.
The beneficial effects of the present invention are: one-way heat conduction film of the present invention is made of columnar fiber unit one by one,
The pipe diameter size of columnar fiber unit is easy to adjust, and columnar fiber unit is smaller, and heating surface is more accurate, so that printing precision can
With adjustment, printing effect is improved, using graphite and grapheme material, printing can be improved while guaranteeing high heat conduction efficiency
Precision.The thin-film material simple production process, low in cost, the shortcomings that conventional laser can be overcome directly to touch have very high
Industrial value.
