Step 3:The slice file generated in step 2 is transmitted to the 3D printing successively according to sequence from bottom to up It runs on machine, then sprays the mixed slurry generated in step 1 to printing bottom plate by the print head of the 3D printer On, until all slice file end of transmissions, complete the structure of reconstruction turquoise micro-structure;
Step 4:The reconstruction turquoise micro-structure obtained in step 3 is sent to Muffle furnace and is heated up to 1200 DEG C, then with Muffle furnace is heated up to 1500 DEG C by the rate of 100 DEG C/h, keeps the temperature 12h, by the reconstruction when Muffle furnace being then cooled to room temperature Turquoise micro-structure is taken out;
Step 5:By sand paper, by treated in step 5, the reconstruction turquoise micro-structure carries out grinding and buffing Processing, you can obtain final reconstruction turquoise.
Further, in the step 2, the mathematical model is directed into Slice Software, is set in the Slice Software It sets several parameters and generates multiple slicing layers, the mathematical model can be sliced using multiple slicing layers.
Further, the Slice Software uses cura Slice Softwares, several parameter packets being arranged in the Slice Software Include floor height, rate of extrusion and pumpback distance.
Further, in the step 2, the floor height of each layer slice is 0.01mm-2.0mm.
Further, in the step 3, the print head of the 3D printer is by the mixed slurry according to slice file Sequence print the micro-structure of every layer of slice successively on printing bottom plate, the micro-structure of all slices collectively forms the reconstruction Turquoise micro-structure, and the micro-structure of each layer of slice prints after terminating, the print head of the 3D printer can be along vertical Certain distance is raised in direction, until stopping after the micro-structure printing being all sliced.
Further, each time the print head of the 3D printer raise apart from all same.
Further, in the step 1, the temperature to injection pipeline heating is 120-130 DEG C.
Further, in the step 1, the raw material powder and additive slurry of the turquoise in the injection pipeline It is stirred by blender, and the mixing time of the blender is 18-25min.
Further, in the step 2, the mathematical model is established by Modeling and Design software, and the Modeling and Design is soft Part uses rhino design softwares.
Further, in the step 4, the granularity of the sand paper is -2000 mesh of 200 mesh.
The advantageous effect that technical solution provided by the invention is brought is:Mathematical model is established to reconstruction turquoise first, is led to It crosses Slice Software and carries out slicing delamination, and establish reconstruction turquoise layer by layer according to every layer analysis structure, it is real in the rank of micro- macroscopic view Show and reconstruction turquoise has been precisely controlled, until completing the structure of micro-structure, constructed micro-structure etc. in vertically and horizontally printing Turquoise is reproduced than reproducibility, compensates for the unicity of tradition reconstruction turquoise material construction, realizes that macroscopical level is distinguished, compares In traditional jade carving, the plasticity and scope of design of turquoise handicraft model have been widened significantly, while improving simulation Accuracy, it can be achieved that turquoise powder recycling, efficiently build High Accuracy Parameter model simultaneously print, shorten model system Make the duration, promotes the reliability of jewels and jade recreation.
Description of the drawings
Fig. 1 is a kind of flow chart of the 3D printing technique based on reconstruction turquoise design of material of the present embodiment.
Specific implementation mode
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with attached drawing to embodiment party of the present invention Formula is further described.
Referring to FIG. 1, embodiment of the invention discloses that it is a kind of based on reconstruction turquoise design of material 3D printing technique, It illustrates, includes the following steps so that printing reconstruction turquoise raw material powder is the reconstruction turquoise of material as an example,
Step S1:The raw material powder of turquoise and additive slurry are seated in the injection pipeline of 3D printer, together When temperature in the injection pipeline is heated to 120-130 DEG C, and pass through auger 18-25min so that the raw material of turquoise Powder and additive slurry, which are uniformly mixed, obtains mixed slurry;
Step S2:It designs and establishes after the mathematical model of reconstruction turquoise using Modeling and Design software rhino and export stl texts The stl files for establishing mathematical model are input in Slice Software cura by part, and floor height is arranged in Slice Software cura, squeezes out The mechanical parameters such as rate and pumpback distance, after being arranged successfully, the Slice Software cura is generated to be parallel to 3D printer The printing N number of slicing layer of bottom plate is sliced mathematical model, and the mathematical model is divided into N+1 layers of slice, is cut from bottom to up It is cut into first layer and is sliced file to N+1 layers of slice file, wherein N is the integer more than zero;
Step S3:The slice file for setting first layer slice is transmitted on the 3D printer and is run, it then will step The mixed slurry generated in rapid one is sprayed by the print head of the 3D printer to carrying out printing until first on printing bottom plate Layer slice printing terminates, and the print head of the 3D printer is vertically then raised certain distance, will then be set The slice file of second layer slice be transmitted on the 3D printer operation and printed, when second layer slice printing terminates Afterwards, the print head of the 3D printer vertically raises certain distance again, and so on, successively to the 3D printer It is upper transmission the 3rd layer slice slice file ..., n-th layer slice slice file and N+1 layer be sliced slice files, often After printing terminates one layer, the print head of the 3D printer can vertically raise certain distance, and described each time The distance that the print head of 3D printer is raised is the floor height of corresponding every layer of slice, and in the present embodiment, each layer is cut The floor height of piece is identical, then the distance that and each time the print head of the 3D printer is raised is also identical, until N+1 layers of slice are beaten Print terminates, and completes the structure of reconstruction turquoise micro-structure;
Step S4:The reconstruction turquoise micro-structure obtained in step 3 is sent to Muffle furnace and is heated up to 1200 DEG C, then with Muffle furnace is heated up to 1500 DEG C by the rate of 100 DEG C/h, keeps the temperature 12h, is finally cooled to the reconstruction turquoise is micro- after room temperature Structure is taken out, and the sintering processes to reproducing turquoise micro-structure are completed, and general room temperature is 20 DEG C -25 DEG C;
Step S5:With -2000 mesh sand paper of 200 mesh by treated in the step 4 reconstruction turquoise micro-structure gradually Grinding and buffing processing, you can obtain final reconstruction turquoise.
Further, the floor height in the step 2 is the height of each layer of slice, and rate of extrusion is the speed that slice squeezes out Degree, pumpback distance are the distance of slurry syringe retraction when raising certain distance after covering one layer of slice.
