and then in the cleaner IPA for another 2 minutes. The actual soaking time depends on the resin used 
and the model structure. If necessary, use a squeegee bottle filled with clean IPA to do the last cleaning. 

24.  Leave or gently blow the model until it dries. 

25.  Remove the model from the platform with a blade or a metal scraper.     

WARNING:

 

Be careful not to cut your fingers.

   

 

 

 

26.  Post cure your model under a UV lamp or sun. Usually, 30 minutes under an UV lamp is enough. Under 

the sunshine, you would need to rotate the model every 15 minutes for an hour. You can soak the model 
in the water to block the oxygen to accelerate the post curing.   

27.  Use a cutter to remove the supports.       

28.  You may need to polish the surface with supports.   

 

V. Z zero Calibration 

 

Normally, you do not need to calibrate Z zero. You need to calibrate the z zero only when a new platform is 
used for the first time. Please refer to the video.

1.  Loosen the four screws on the side of the platform.   
2.  Lift the bottom flat piece up as much as possible. 
3.  Tighten these four screws a little bit. 
4.  Press the “Home” button. 
5.  Loosen those four screws and lay the platform flat on the LCD. 
6.  Press the bottom piece gently to fix it on top of the LCD.    Take turns to tighten these four screws in 

sequence. You may need to do this for a few rotations.   

7.  Check if there is any gap between the vat floor and the build. If a gap is found, repeat steps 5 to 7.
