Part I: Work with model in UNIZ Dental V2 software.

1. Select Printer model - Printer – Indication: Dental Casting - Proper profile, and click on Next (take NBEE as an example).
   
1. Select the corresponding profile of the resin that you will use.
   
   
   
   
2. Double-click the profile to view all detailed parameters of the resin. If the printed dental cast do not fit optimally, you can adjust the inner wall thickness of the parts by modifying the Internal Compensation. T
   o make it loose, set positive value, to make it tight, set negative value, the larger the value, the more obvious the effect. For the functions of internal and external compensation, please refer to the following image.
   
   
   
   
   
   
   
   
   
2. Import dental cast STL models.
   
1. Select the STL files from your computer and import them.
   
   
   
   
3. Adjust the layout of the model.
   
1. Ensure a safe distance between models.
   
2. Make sure the occlusal surface is facing down.
   

   

   
   
4. Automatic support.
   
1. Select all models and click "Generate" to generate supports using the default support parameters (if the supports of printed part are not proper or very difficult to be removed, please change the default parameters or adjust the detailed support parameters by switching to the advanced interface of settings). The recommended lift height is 4mm.
   
   
   
   
   
   

   
   

   
   
   
5. Manual adjustment of supports:
   
1. Click Manual to enter manual editing mode. Add support - left click on the location where support is insufficient; Reduce supports - Left click on any extra supports and press the Delete key to remove them.
   
   
   
   
   
   
   
6. Slicing.
   
1. Preview the sliced model after slicing to make sure the model has no overhanging faces.
   
   
   
   

Part II: Printing models

1. Ensure Optimal Working Conditions:
   
1. Place the printer on a flat, stable place, and make sure the wheels, build platform, and resin tank are securely locked.
   
2. Verify that the resin tank is within its lifespan and that there are no residues left on the build platform or in the resin tank.
   
3. Ensure that both the UI firmware and system firmware are updated to the latest version.
   
4. Thoroughly mix the zDental Cast resin before pouring it into the resin tank.
   
2. Use at least 200ml to prevent print failures due to insufficient resin.
   
3. Select the slicing file in the printer and initiate the printing process.
   

Part III: Post-processing

1. Detaching.
   Detach the printed modes from the build platform with UDetach (automatically), or with metal scrapper (manually).
   
   
   
2. Cleaning
   
1. Clean the printed gingiva with UWash (UNIZ ultrasonic washer) and alcohol (greater than 90% concentration) or IPA for 2 minutes (twice, one minute for each time).
   

   

   
   
3. Drying.
   
1. Dry the printed parts with compressed air after cleaning. Ensure the surface is clean and dry.
   
   
   
   
4. Curing.
1. Cure the printed parts with UCure (UNIZ curing machine). Select zDental Cast settings (level 1, 1 minutes for each side, totally need 2 minutes), then click Start.
   
   
   
   
5. Fitting test.
   
1. If the fit is not optimal, please return to Step 1 of Part I to modify the Internal Compensation for adjustment, then print again until the fit is satisfactory.
