Embodiment 1

[0085] This embodiment provides a printing method of a 3D printer for cement-based materials. The 3D printer provided by this embodiment is as figure 1 As shown, the front view of the z-axis system of the 3D printer of the cement-based material in this embodiment is as figure 2 As shown, the top view of the z-axis system of the 3D printer of the cement-based material in this embodiment is as follows image 3 shown.

[0086] Step 1, through the mobile phone APP, use the wireless transmission / reception system to set the printing parameters.

[0087] The stirring time of the stirring system is 1min, the stirring rate is 90 rpm, the extrusion rate of the extrusion system is 3mm / s, the printing layer thickness is set to 1mm, the filling mode is grid filling, the filling density is 30%, the printing speed 70mm / s, idling speed 100mm / s. And transmit the corresponding parameter command to the corresponding system through the network, and then control the operation of the printer. ...

Embodiment 2

[0093] This embodiment provides a printing method of a 3D printer for cement-based materials.

[0094] Step 1, carry out the input and output system to set the printing parameters.

[0095] The stirring time of the stirring system is 2min, the stirring rate is 50 rpm, the extrusion rate of the extrusion system is 2mm / s, the printing layer thickness is set to 2mm, the filling mode is linear filling, the filling density is 20%, and the printing speed is 50mm / s, idling speed 80mm / s. The corresponding parameter command is transmitted to the corresponding system through the network, and then the operation of the printer is controlled.

Abstract

The invention relates to a 3D printer and a printing method thereof. The 3D printer comprises a control system, a material system, a stirring system, an extruding system, a xy-axis system, a z-axis system, a wireless sending / receiving system and an input and output system, wherein the control system is used for controlling the stirring system, the extruding system, the xy-axis system and the z-axis system; the xy-axis system controls a printing sprayer to move in the xy-axis direction; and the z-axis system comprises a forming powder storage cylinder, a forming cylinder, a powder paving roller, a function material storage cylinder and a spiral cloth roller. The 3D printer adopts the 3D printing technology to successfully construct cement-based material, gypsum and other powder material, and functional material into a solid model with certain function so as to provide hardware equipment and technological support for application of the 3D printing technology in the industries of building materials, buildings, industrial arts, medical treatment and the like, and creation of novel functional material is facilitated.

Description

technical field [0001] The invention relates to a printing technology, especially a printing technology of building materials such as cement-based materials or gypsum and materials with specific functions, which can form gradient functional materials. Background technique [0002] Rapid prototyping technology is a new modeling technology originated in the United States in the late 1980s. This technology "prints" the three-dimensional entities in the computer layer by layer through the accumulation of materials, so it is often called 3D printing technology. . The existing 3D printing technologies mainly include stereolithography (SLA), laminated object manufacturing (LOM), selective laser sintering (SLS), and fused deposition modeling (FDM). [0003] 3D printing technology has applications in jewelry, footwear, industrial design, automotive, aerospace, medical, military and other fields, and the technology has also sparked a boom in the construction industry. Compared with ...
