The printing range (work area) uses the rear side of the liquid material vat. After the machine has been used for a while, the bottom of the liquid material vat turns
cloudy white. When the liquid material vat gets too cloudy, printing becomes impossible (the resin stops solidifying and the job sticks to the liquid material vat).
MEMO
The part of the printing range that is not cloudy can still be used to print. Position the object so as to avoid the cloudy part.
If the printing range shown in the figure above is completely cloudy, it is possible to use the remaining half of the liquid material vat by rotating it 180°.
