specific Embodiment approach 1
[0019] Print the concrete main structure of the building, using fiber materials plus concrete to replace the traditional reinforced concrete structure
[0020] The following steps are involved in printing the concrete main structure of a building:
[0021] a. Establish a three-dimensional building computer model, slice and layer it, determine and fill the boundary, get all the pixel information of each layer, perform data processing, plan the printing path, and start printing. After the PC sends a command line to the device;
[0022] b. The printing main board controls the three-axis reset, detects the status of each sensor, and confirms that the machine is normal and the printing materials are sufficient;
[0023] c. The printing control circuit controls the feeding speed, feeding on-off, and running speed, and the concrete printing head prints one layer along the movement track sent by the PC at the same height level;
[0024] d. The X and Y-axis guide rails of the printing...
specific Embodiment approach 2
[0027] Use thermoplastic materials to print special-shaped building templates or building decoration components, so you don't need to work on the construction site. Because 3D printing is to stack sections from bottom to top, when making shapes with suspended parts, it is necessary to use support structures to provide support
[0028] The device of the present invention uses the same material as the component entity when printing the support structure, but the support structure is printed sparsely, and the support structure is removed after the printing job is completed
[0029] The following steps are included when printing special-shaped building formwork or building decoration components:
[0030] a. Establish a three-dimensional building computer model, slice and layer it, determine the boundary, fill it, set the support reasonably, obtain all the pixel information of each layer, perform data processing, plan the printing path, and start printing. After the PC sends the me...

Abstract
The invention discloses three-dimensional printing equipment used in the building industry. The three-dimensional printing equipment used in the building industry comprises a body structure, a printing head device, a control unit and a data processing unit. The printing equipment aims to improve the building construction efficiency, save building materials, reduce cost, improve building construction environment, and solve the problems that the manufacturing difficulty of a current special-shaped formwork of the building industry is large, and cost is high.
Description
technical field [0001] The invention belongs to the field of 3D printing, and in particular relates to a 3D printing device used in the construction industry, which is used for printing concrete walls of houses, sculpture buildings, building templates and building decoration components. Background technique [0002] 3D printing is a kind of rapid prototyping technology. It is a technology based on digital model files, using powder, filamentous materials, and liquid curable materials to construct objects by layer-by-layer printing. 3D printing is a kind of additive manufacturing technology. After slicing the three-dimensional solid, it is formed layer by layer according to the contour section, and then superimposed to obtain the final product. [0003] The current mainstream 3D printing technologies include: Fused Deposition Modeling (FDM), Stereolithigraphy Apparatus (SLA), Three Dimensional Printing and Gluing (3DP), Selective Laser Sintering Type (Selecting Laser Sinterin...
