Deng manufacturing cost is higher, expensive, is unfavorable for commercial application in industry.Publication No. CN105215281A application, it is public
A kind of 3D printing quartz precoated sand preparation method is opened, primary raw material is quartz sand, after SDS aqueous solution pretreatment, is made
It is stirred for primary raw material together with a variety of organic reagents such as acetone, 3D printing quartz precoated sand is obtained after drying and grinding.But
It is that the quartzy precoated sand preparation process used in the patent is complicated, cost is high, and is divided into the middle part of organic reagent used poisonous
Reagent, environmental pollution is easily caused, be unfavorable for industrial industrialization application.Patent CN204658979U discloses a kind of 3D printing and set
Standby, using layer of sand is laid based on quartz sand, UV epoxy glues bonding forms 3D printing product.But the patent is beaten for 3D
Printing apparatus, the dioxide-containing silica and granularity of quartz sand used are not related to, also without the strong of open gained 3D printing product
Whether degree increases, and therefore, how to design and develops the high 3D printing dusty material of a kind of low cost, intensity, turn into this
The technical problem of urgent need to resolve in field.
The content of the invention
The present invention has that manufacturing cost is high, expensive, printing physical components are strong for 3D printing material in the prior art
Spend the problem of low, there is provided a kind of 3D printing dusty material, the physical components that the 3D printing is printed with dusty material
Intensity is high, cost is low, operation is easy.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of 3D printing dusty material, it is characterised in that：The dusty material is varigrained quartz sand, its granularity
Scope is between the mesh of 50 mesh -200；The granularity of the quartz sand configures in the following proportions：The content of 50 mesh below 1% parts by weight,
The content of 70 mesh is between 10% to 20% parts by weight, and between 25% to 40% parts by weight, the content of 140 mesh exists the content of 100 mesh
Between 30% to 45% parts by weight, the content of 200 mesh is between 5% to 10% parts by weight.
Further, in described quartz sand, silica accounts for the 95% of overall quartz sand weight.
Further, in described quartz sand, the content of 50 mesh granularities is reduced.
Further, described quartz sand adds machine mixer after the completion of proportionally being configured according to granularity difference
Middle mixing.
Further, the dusty material carries out sanding printing by 3D printing equipment, takes out printing test block, it is anti-to detect it
Compressive Strength.
The technique effect of the present invention is as follows：
（1）Raw materials for production used in the present invention are quartz sand, are that quartz warp crushes the quartz particles being process, day
So exist, price is relatively low, and the main chemical compositions of quartz sand are silica, its account for overall quartz sand weight 95% or
Person is higher, can reduce the alkalescence of product, reduces the addition of curing agent, so as to reduce printing cost, and effectively avoids
The layering of dusty material in course of injection；
（2）Printing entity compression strength obtained by the present invention is high, good product performance；
（3）Printing entity products obtained by the present invention can make gap be reduced to less than 15%, improve the degree of packing.
Embodiment
In order that those skilled in the art more fully understand technical scheme, with reference to specific embodiment to this
Invention is described in further detail.
3D printing dusty material of the present invention, is varigrained quartz sand, raw materials for production quartz sand used
Granularity configure in the following proportions：The content of 50 mesh below 1% parts by weight, the content of 70 mesh between 10% to 20% parts by weight,
The content of 100 mesh is between 25% to 40% parts by weight, and between 30% to 45% parts by weight, the content of 200 mesh exists the content of 140 mesh
Between 5% to 10% parts by weight.Meanwhile need to control the content of 50 mesh granularity quartz sands as far as possible during proportioning, make it
