9. Common problems and maintenance

9.1 Q & A

9.1.1 Why does the model not stick to the platform?

(1) The release film is loose or damaged. Just tighten the fastening screw at the

bottom of the trough to loosen the release film would be fine. If the release film is

scratched, bulged, or has stains that cannot be removed, then the release film needs to

be replaced;

(2) The contact area between the bottom of the printed model and the release film is

too small. At this time, it is necessary to add a bottom raft when slicing;

(3) The exposure time of the bottom layer is not enough. Generally, the exposure time

of the bottom layer should be 8-12 times of the normal exposure time;

(4) The leveling is not adjusted properly. This situation will cause the print platform to

be high while the other is low or the first layer of printing is too high, so the resin

cannot be cured completely within the normal exposure time, resulting in the model

not sticking, and it needs to be re-leveled at this time;

(5) The cross-sectional area of the printed model is too large. After curing a layer with

a larger cross-sectional area, since the resin cannot reflow to the middle area in time,

there may be missing features in the middle part of the model. At this time, the lifting

distance should be increased when slicing;

(6) The LCD screen is damaged. The LCD screen is dark or not on, In this case, check the

circuit first. If it is confirmed that the LCD screen is broken, please replace the LCD

screen.

9.1.2 Why does the model have faults or cracks?

(1) The machine shakes during printing. The machine needs to be placed in a relatively

flat place;
