The distance between the platen assembly 300 and the extrusion head assembly 200 is adjusted mainly according to the viscosity of the slurry and the printing precision requirement. For slurry materials with high viscosity and high precision of 0.1mm, the distance between the workbench component 300 and the extrusion type spray head component 200 needs to be controlled between 0.13mm and 0.15mm in actual processing; for slurry materials with low viscosity and high precision of 0.1mm, the distance between the workbench assembly 300 and the extrusion nozzle assembly 200 needs to be controlled between 0.12mm and 0.14mm in practical processing.
The extrusion nozzle assembly 200 and the laser sintering assembly 400 are kept stationary during the processing, and the stage assembly 300 is moved in three directions of XYZ. The initial adjustment of the focal position of the laser sintering assembly 400 is mainly achieved by changing the optical path system 402, and different lasers 401 and laser powers are used for processing according to different materials to be processed.

The discharging nozzle 205 is mainly selected according to the property of the slurry material and the printing precision requirement, and generally, the higher the printing precision requirement is, the smaller the particle size of the slurry is, the smaller the viscosity of the slurry material is, and the smaller the size of the discharging nozzle 205 is.
