Use the “Slice” Tool
The “Slice” tool in 3D Builder allows you to split your model down the middle, creating two separate halves.
To use the “Slice” tool:
1. Open your model in 3D Builder.
2. Select the “Slice” tool from the toolbar.
3. Click and drag on the model to create a cutting plane.
4. The model will be split into two halves along the cutting plane.
You can adjust the settings of the “Slice” tool to change the thickness of the cutting plane and the direction of the cut.
The following table summarizes the different settings for the “Slice” tool:
| Setting | Description |
|---|---|
| Thickness | The thickness of the cutting plane. |
| Direction | The direction of the cut. |
| Keep Both Halves | Determines whether both halves of the model are kept after the cut. |
Position the Cut
Determining the precise location for the cut is crucial for achieving a successful split. Here’s how you can determine the cut line:
- Identify the cutting plane: Visualize a plane that divides the model into two equal halves. This plane should be perpendicular to the model’s main axis or the axis of symmetry.
- Use the “Measure” tool: Activate the Measure tool from the “Tools” tab. Hover over the model’s surface and click two points along the desired cut line.
- Read the measurements: The Measure tool will display the distance between the two selected points. Note down this value for reference.
- Set the plane offset value: Click on the “Split” tool from the “Edit” tab. Adjust the “Plane Offset” value in the toolbar to match half of the measured distance. This offset determines the distance from the model’s center to the cutting plane.
| Steps | Details |
|---|---|
| Identify cutting plane | Visualize a perpendicular plane dividing the model in half. |
| Use Measure tool | Measure the distance between two points on the cut line. |
| Set plane offset value | Enter half of the measured distance as the plane offset value in the Split tool settings. |
Adjust Cut Settings
To ensure a clean and precise cut, you need to adjust the cut settings accordingly. Here are the key parameters:
Cut Speed
This setting determines how quickly the laser moves along the cut path. A higher cut speed will reduce the cutting time but may produce a rougher edge. For intricate designs, use a slower cut speed to ensure accuracy.
Laser Power
The laser power setting controls the intensity of the laser beam. Higher power will result in faster cutting but may cause heat distortion in the material. For delicate materials like acrylic, use lower power settings to minimize potential damage.
Focus Distance
This setting determines the distance between the laser nozzle and the surface of the material. It affects the thickness of the laser beam and the cutting depth. Ensure that the focus distance is set correctly based on the material thickness and type.
Number of Passes
In some cases, a single pass of the laser may not be sufficient to completely cut through the material. You can adjust the number of passes to ensure a clean cut. Multiple passes will take longer but will produce a more refined result.
Feed Rate
The feed rate refers to the speed at which the material moves under the laser head. A higher feed rate will result in a faster cut but may cause the material to vibrate. For thin or delicate materials, use a lower feed rate to prevent damage.
| Parameter | Optimum Setting |
|---|---|
| Cut Speed | 20-50 mm/s |
| Laser Power | 50-80% |
| Focus Distance | 2-3 mm |
| Number of Passes | 1-2 |
| Feed Rate | 5-10 mm/s |
Preview Split
Preview Split allows you to view a cross-sectional preview of your model as you split it. This can be helpful for ensuring that you are splitting the model in the correct location.
To use Preview Split:
- Select the model that you want to split.

If you encounter errors while performing a split down the middle operation in 3D Builder, here are some potential causes and solutions:
1. Incorrectly Selected Model: Ensure you have selected the 3D model you wish to split.
2. Unsupported File Format: 3D Builder may not support the file format of the model you’re using. Check if the file is in a supported format such as STL, OBJ, or 3MF.
3. Complex Model Geometry: Highly complex models with intricate details may not split cleanly. Try simplifying the geometry or using a different splitting method.
4. Invalid Cut Parameters: Ensure the cut parameters, such as offset and thickness, are valid and not resulting in an invalid operation.
5. Hardware Limitations: If your device lacks sufficient processing power or memory, splitting operations may fail. Consider using a more powerful device or optimizing your model before attempting the split.
6. Software Bugs: Check if there are any known software bugs related to splitting operations in the current version of 3D Builder. Update to the latest version or report the issue to the developers.
7. Corrupted Model: Verify the integrity of your 3D model file by opening it in a different CAD software. Repair any errors or re-export the model with proper settings.
8. Advanced Troubleshooting
For advanced troubleshooting, consider the following:
a. Check Model Boundaries: Examine the model’s boundaries and ensure they are clearly defined. Remove any overlapping or intersecting surfaces that may prevent a clean split.
b. Use a Different Splitting Tool: Try using an alternative splitting tool or method, such as using a Boolean operation in a CAD software. This can provide a different approach to the split and may resolve any issues.
c. Experiment with Cut Settings: Experiment with different offset and thickness values during the split operation. Adjust the settings incrementally and observe the results until you achieve the desired split.
d. Optimize Model for Splitting: Simplify your model by removing unnecessary details or splitting it into smaller sections. This can reduce the computational complexity and improve the success rate of the operation.
Optimize Cut Quality
Use Sharp Blades
Dull blades will tear the filament, resulting in a rough and ragged cut. Make sure to use sharp blades that are specifically designed for cutting 3D prints.
Adjust Cut Speed
The cut speed should be slow enough to allow the blade to cleanly cut through the filament without causing excessive melting or tearing. Experiment with different cut speeds to find the optimal setting for your specific material and blade.
Use a Cutting Fluid
A cutting fluid can help to lubricate the blade and prevent the filament from sticking to it. This can result in a cleaner and smoother cut.
Support the Model
Make sure to support the model adequately during cutting to prevent it from flexing or vibrating. This will help to ensure a clean and precise cut.
Use a Sacrificial Layer
If you are cutting a model with a thin or delicate feature, consider using a sacrificial layer. This is a thin layer of material that is added to the bottom of the model to support the feature during cutting.
Cut in Multiple Passes
For thick or complex models, it may be necessary to cut in multiple passes. This will help to prevent the blade from overheating and tearing the filament.
Use a Fine-Toothed Blade
A fine-toothed blade will produce a cleaner and more precise cut than a coarse-toothed blade. However, it is important to note that a fine-toothed blade will also cut more slowly.
Use a Cutting Mat
A cutting mat will help to protect your work surface from scratches and nicks. It will also provide a stable surface for cutting.
Experiment with Different Settings
The optimal cut quality settings will vary depending on the specific material, blade, and model. Experiment with different settings to find the best combination for your needs.
Best Practices for Splitting 3D Models
