Abstract:
The main parameters affecting small-scale 3D printing with clay as raw material(including moisture content, printing linear speed and printing layer height)were comprehensively studied. The printing properties of clay paste under different conditions were determined through experiments, including flowability, extrudability, and buildability of clay slurry. Firstly, the relationship between extrusion pressure and slurry extrusion rate in 3D printing system was studied, and the extrusion rate was controlled by adjusting the air pump pressure according to the relationship. The influencing parameters of clay moisture content, printing linear speed and printing layer were changed respectively to carry out 3D printing with clay. The rheological test on the printing specimen was carried out, the forming condition of the specimen was observed, and the relative deviation of the printing specimen was measured, the results were used to evaluate the flowability, extrudability and buildability of clay slurry respectively. The results show that the moisture content of clay most suitable for 3D printing is 34%-35%, which is 3%-4% higher than the liquid limit of clay. The best printing line speed is 4-5.5 mm·s-1. The best printing layer height is 1.4-1.8 mm, which is about 1-1.3 times of the nozzle diameter. The setting of printing parameters should consider not only the characteristics of printing materials, but also the characteristics of printing system. The value of each parameter should also be constrained by the law of mass conservation. During the 3D printing test of clay, after determining the nozzle size of the printer, the moisture content of clay shall be determined firstly, and then the parameters such as linear speed, layer height, extrusion rate and extrusion pressure of the printing system shall be determined.
