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

Select Indication and Parameter

Import File

        Import your try-in mandibulor and maxillary STL file into Uniz Dental.

Orient and Layout 

       Use the view tool and manipulator to adjust the orientation.

Notes: To optimize support structures and minimize isolated sections during printing, ensure the try-in's occlusal surface faces away from the build platform. Additionally, position the anterior plane at a 20 to 30-degree angle from the horizontal. This orientation reduces unsupported areas, enhancing print quality and efficiency.

Generate  Supports

1. Manually add supports: Follow the supports setting showed in the picture, and click Manual
   
   

   Notes: To optimize your 3D printing process, you have the option to select between "Linear" and "Full" raft types. Ensure that the minimum lift height is set to 4mm. If you find the supports difficult to remove, consider reducing their density or strength to facilitate easier detachment. For experienced users, you can also adjust every detailed supports parameter by switching to advanced interface in settings menu of UNIZ Dental V2.
2. Swith to bottom view, select the model and zoom in or out and move your mouse to add supports to the ridge of opposite side of occlusal plane. Make sure no supports generate in the fitting area.

3. Click Apply to generate supports
   

Slice

1. Click Slice to get slicing file (zslr. format)
   
   
   
2. To ensure successful 3D printing, it's essential to preview the sliced model layer by layer. After slicing, use the slicer's preview feature to inspect each layer by dragging the slicer bar up and down. Pay particular attention to the ridge areas, confirming they have adequate support structures. Additionally, look for model errors such as suspended triangular facets. If such issues are present, it's advisable to repair the model using professional software. Tools like MeshInspector offer advanced features for mesh analysis and repair, enabling you to identify and fix inconsistencies such as holes, non-manifold edges, and intersecting surfaces, ensuring your model is optimized for high-quality printing.
   
   
   

Part II: Print

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 in a good condition and that there are no residues left on the build platform or in the resin tank.
   
3. Thoroughly mix the try in 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.
   Refer to Printing Tips for optimal result.

Part III: Post Process

1. Removing the print
   Use UDetach, the automatic model removal device, to remove or manully remove by using metal scrapper.
   
   
   
2. Support removal
   
1. Manually remove or use small scissors or flat-nose pliers to cut the supports. Be careful not to apply too much force to avoid breakage.
   
   
3. Cleaning
   
1. Clean the printed Try-In with UWash (UNIZ ultrasonic washer) and alcohol (greater than 90% ) or IPA with the concentration over 92% for TWO round wash, each round takes 2 minutes.

   

   
   
4. Drying
   
1. Use a compressed air gun to blow dry for 3 minutes or let it sit to air dry for 30 minutes.
   
   
   
5. Curing
1. Cure the printed parts with UCure (UNIZ curing machine). Select zDental Splint Soft settings (level 3, 15 minutes for each side, totally need 30 minutes), then click Start
   
   
   
6. Polishing
   
1. Use an electric sander (preferred) or sandpaper to smooth out the residual support points on the model, making the surface smoother.
   
2. 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.
   
3. Wash and dry after polishing.
   
   
7. Fitting Test.
   
1. If the fit is not optimal, please refer to Accuracy Calibration or Fitting Adjustment
