Abstract
The invention discloses powder for 3D printers and a preparation method thereof. The powder comprises the following components in mass percent: 55%-80% of gypsum, 1%-10% of anhydrite, 1%-10% of barium sulfate, 10%-20% of polyvinyl alcohol, 1%-5% of aerosol and 1%-5% of lecithin, and is prepared by grinding and mixing the components. The powder can effectively improve precision of a printed object and accuracy of printing size, avoids such problems as high frequency of printer failure and blockage of a printing head caused by flying powder.
Description
Technical field
The present invention relates to 3D printing technique field, is specifically related to a kind of powder for 3D printer and preparation method thereof.
Background technology
3D printing technique claims again three-dimensional printing technology, refers to the 3D printer that goes out real-world object by can " printing ", and the mode that adopts layering processing, superposition to be shaped successively increases material and generates 3D entity.The most outstanding advantage of 3D printing technique is without mechanical workout or mould, just can directly from computer graphics data, generate the object of any shape, thereby greatly shortens the lead time of product, boosts productivity and reduces production costs.
The core of 3D printing technique development does not lie in printing, but be the restriction of material technology, only have new material technology to develop, 3D printing technique could be further practical, at present 3D printer has been used for making mould, skeleton etc., can certainly be used for printing relatively simple daily necessities.Current consumptive material is totally divided into several classes: powdery type consumptive material, for laser sintering and moulding; Photosensitive class consumptive material, for Stereolithography; Melting silk material class consumptive material, for Deformation In The Fdm Process; Also have paper consumptive material, plastic-blasting consumptive material etc.
Existing powdery type consumptive material, in 3D prints, exists printing objects precision not high, stamp with the size out of true, and hold susceptible to plugging problem because waving of powder causes the increase of printer fault and printhead.
Summary of the invention
For overcoming the defect of prior art, be of the present inventionly to provide a kind of powder for 3D printer, improve the precision of printing objects and the accuracy of stamp with the size, avoid waving of powder to cause printer fault to increase and the problem such as printhead obstruction.
Another object of the present invention is to provide a kind of preparation method of the powder for 3D printer, to obtain a kind of 3D printer powder that tolerance range is high, can not stop up printhead and minimizing printer fault of printing.
The technical solution adopted in the present invention is as follows for achieving the above object:
For a powder for 3D printer, it is to be prepared from by the following component of calculating by weight percentage:
Gypsum: 55%-80%
Anhydrite: 1%-10%
Barium sulfate: 1%-10%
Polyvinyl alcohol: 10%-20%
Aerosil: 1%-5%
Yelkin TTS: 1%-5%.
The present invention can also realize by following scheme:
As the preferred scheme of one of the present invention, the described powder for 3D printer is to be prepared from by the following component of calculating by weight percentage:
Gypsum: 75%
Anhydrite: 3%
Barium sulfate: 3%
Polyvinyl alcohol: 16%
Aerosil: 1%
Yelkin TTS: 2%.
In the present invention, gypsum is main formed material, meets water cure moulding; Anhydrite can increase the intensity of formed article; Barium sulfate increases the proportion of powder, improves the compactness of powder; Polyvinyl alcohol is for increasing the bonding between powder granule; Aerosil increases the mobility of powder granule, strengthens the planeness of powder; Powder when Yelkin TTS can effectively stop powder to be piled up flies upward.
In the present invention, contriver studies and finds the size distribution of gypsum to be controlled at more close limit, is conducive to improve every one deck and prints in the homogeneity of paving powder, guarantees that the thickness of every one deck is average as much as possible, makes the dimension of object that prints more accurate.As the preferred scheme of one of the present invention, when the particle diameter control of described gypsum is 15-20 micron, the accurate performance of printing objects is significantly improved.
Utilize powder of the present invention to print in the process of article, if need to adopt distinct colors, can in the making processes of powder of the present invention, add the toner of different colours, to obtain the printing powder of different colours; Or in the time coordinating tackiness agent to use, adopt colored tackiness agent.
For a preparation method for the powder of 3D printer, it comprises the following steps:
1) steam curing uses physical pulverization method, is ground into the powder particle below 200 orders;
2) mode that barium sulfate is pulverized by gas is ground into the powder granule below 400 orders;
3) select the polyvinyl alcohol below 200 orders;
4) above powder particle uses high-speed mixer to mix, and crosses 200 eye mesh screens;
5) add aerosil and Yelkin TTS, mix; Obtain the powder that can be used for 3D three-dimensional printing.
As the preferred scheme of one of the present invention, described barium sulfate is pulverized by micronizer mill.
Compared to existing technology, beneficial effect of the present invention is:
1. powder of the present invention can effectively improve the accuracy of printing and the tolerance range of printing objects by the particle size range of controlling raw material;
2. in the present invention, can well suppress powder flying upward in the time that every layer of paving powder piled up owing to having added Yelkin TTS, can reduce the clean frequency of printer, extend the work-ing life of shower nozzle simultaneously; 3D compared to existing technology prints powder, and the clean frequency of printer will reduce by 80% left and right, and the life-span of shower nozzle can extend to 60% left and right.
3. preparation method of the present invention is simple, easily operation.
Below in conjunction with concrete embodiment, the present invention is described in further detail.
