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

1. Select Printer model - Printer – Indication: Surgical Guide - 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 drill hole of the printed surgical guide does not fit optimally, you can adjust the inner wall thickness of the drill hole by modifying the Internal Compensation (normal layers). To make it loose, set positive value, to make is 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 surgical guide STL models.
   
1. Select the STL files from your computer to import them.
   
   
   
   
3. Align the bottom surface.
   
1. Click Align Buttom Plane, then move the mouse to the plane around the drill hole on the outer side of the surgical guide and left-click to align this plane as the bottom surface, to make sure the drill hole vertical and perpendicular to the build platform.
   
2. If a surgical guide has multiple drill holes, manually rotate the model so that all drill holes are as close to perpendicular to the build platform as possible.
   
3. In SLA 3D printing, positioning drill holes vertically improves accuracy and facilitates easier fitting adjustments if the fit is not optimal.
   
   
   
   

   
   
   

   
   
   
4. Automatic support.
   
1. Select all models and click "Generate" to generate supports using the default support parameters. The recommended lift height is 4mm (For experienced users, you can also adjust every detailed parameters of supports by switching to advanced interface in settings of UNIZ Dental V2).
   
   
   
   
5. Manual adjustment of supports:
1. Click Manual to enter manual editing mode.
   
   
   
   
2. Hold down the right mouse button and drag to select the support points on the plane near the drill hole (guide ring installation position). Then press DELETE key of the keyboard to delete all supports of this area. Ensure that support points avoid the guide ring installation location and maintain a distance of approximately 2mm from the guide ring, leaving that area free of supports.
   

   

   
   

   
   
   
6. Slicing.

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 zSG Clear resin before pouring it into the resin tank.
   
2. Use at least 200ml to prevent print failures due to insufficient resin.
   
3. Select the slice file 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 surgical guides with UWash (UNIZ ultrasonic washer) and alcohol (greater than 90% concentration) or IPA for 2 minutes.
   
   
   
   
3. Drying.
   
1. Use a compressed air gun to blow dry for 3 minutes or let it sit to air dry for 30 minutes.
   
   
   
4. Support removel.
   
1. Use small scissors or flat-nose pliers to cut the supports close to the model. You can also snap them off by hand, but be careful not to apply too much force to avoid breakage.
   
2. If the surface feels sticky or is not clean after removal, wash it again with clean alcohol (greater than 90% concentration) or IPA for 1 minute.
   
   
   

   
   
   
5. Curing.
1. Cure the printed parts with UCure (UNIZ curing machine). Select zSG Clear settings (level 2, 1 minutes for each side, totally need 2 minutes), then click Start.
   
   
   

   
   

   
   
   
6. Sanding.
   
1. Use an electric sander (preferred) or sandpaper to smooth out the residual support points on the models, making the surface smoother.
   
2. After sanding, ultrasonic clean the models with clean alcohol (greater than 90% concentration) or IPA for 1 minute to remove the white powder generated during sanding.
   
3. During sanding, take proper safety precautions by wearing safety goggles and gloves. Focus on the areas around the support points, sanding until they are no longer visible.
   
   
   
   
7. Surface polishing.
   
1. After cleaning, the surface may show sanding marks. You can apply a small amount of resin to the surface of the surgical guide, being careful not to get any on the interior of the model.
   
   
   
   

   
   
   
8. Curing.
   
1. Finally, use UCure to cure the zSG Clear resin applied to the surface.
   
   
   
   
9. Fitting test.
   
1. Test the fitting of the printed surgical guide with the guide ring. If the hole 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.
