weight sensor on each material roll. An alarm will be given on the screen when the weight of materials
arelower than the materials required by printing. There is heating device in the material chamber, which
can be used for auxiliary drying of material chamber, and the maximum temperature of material chamber
can reach up to 70°C. To ensure the dryness of materials, the slide door of material chamber shall be kept
in closed state all the time. The sliding door are held closed by magnetic force when it is in closed state.
To replace materials or do troubleshooting, the sliding door can be opened by pushing it forward slightly,
and the light will be enabled automatically with the opening of chamber.

3.5 Printing Head Subassembly
The printing head subassembly is used for fusing wire, and forming the required model on the printing
glass plate in combination with the movement of XYZ axis. The subassembly contains two nozzles, of
which the left nozzle is used to print model material and the right nozzle is used to print support material in
normal cases. The left and right nozzle can be switched by the up and down movement of the right nozzle,
and only one nozzle will execute the printing at one time.
There is also feeding state monitoring sensors (each one on the left and right respectively) on the printing
head subassembly, which will alarm for abnormal material feeding. Refer to Chapter 5 for the loading and
unloading of materials.
