Static Load Optimization
Last updated:
September 30, 2025
Learn how to apply forces, set constraints, and generate lightweight optimized designs with Vixiv AI’s static load optimization workflow.
1. Import Your 3D Model to Vixiv AI
- From the Home Page, click “Drag & drop or click to import a 3D model” or use the “Import new file” button in the upper right.
- File format: must be an STL file.

2. Explore the Optimization Workspace
Once your file is open, you’ll see it displayed in a 3D workspace with grid and dimensions.




- Navigation controls:
- Left-click + drag → rotate your part
- Scroll wheel → zoom in/out
- Scene Visualization:
- Toggle axes and grid on/off
- Switch pivot axis (Global or Model)
- Reset view to default (⟳)
- Material Visualization:
- Adjust STL color and opacity
- Show/hide wireframe
- Show/hide force arrows
- Section View:
- Enable/disable section cut
- Choose a plane and clip position
- Reverse the section view direction
3. Apply Force and Constraints
Static load optimization requires selecting both a load surface and a fixed surface.
- Load (Green):
- In the upper left, select Load.
- Click on the surface where you want to apply force (highlights in green).
- Optional: specify a force direction. If left blank, the force is normal to the surface.
- Remove a load by clicking the same surface again.
- Fixed Face (Red):
- In the upper left, select Fixed Face.
- Choose the surface that represents attachment (e.g., bottom surface on a floor, side of an angle bracket attached to a wall).
- Surface highlights in red.
- Remove by clicking again.
- Tolerance:
Adjust tolerance to capture more of a curved surface.- Low tolerance = fewer triangles selected
- High tolerance = more triangles included


4. Set Optimization Requirements
- Domain: Static loading (upcoming domains: Vibration, Thermal, Fluidics, Multi-physics).
- Printer: HP MJF 5200 (upcoming printers: FDM, SLA, and other manufacturing methods)
- Material: Currently trained on PA 12 (upcoming materials: more polymer materials, metallics)
- Shell Thickness: Default 1 mm (0.039 in). Maintains a perimeter “skin” for drilling or attachments. Toggle between SI and imperial units.
- Zero Thickness Direction: Allows powder removal (required for powder-based printers like MJF). Choose an axis or “None” for enclosed lattices.
- Optimization Goal: Optimize for Max Load or Stiffness.
- Currently supported loads: 0–10,000 lbf (0–44,482 N)
- Generated outputs will satisfy the inputed optimization goal
5. Generate a Design
Click Generate to start optimization. Vixiv AI will generate a table of up to 21 unique solutions that all satisfy optimization goal.
- Est time: ~10 minutes.
- There is no token cost if zero designs are generated.
- Table color code:
- Green → easiest to manufacture/unpack based on printer.
- Yellow → moderately challenging based on printer.
- Red → hardest to manufacture/unpack based on printer.
- Note: “Red” doesn’t mean bad — it may provide the best stiffness or mass reduction depending on your needs.

6. Review, Sort, and Export
- Sort designs by your priorities (mass reduction, stiffness, etc.)
- Preview output designs directly in Vixiv AI by selecting individual outputs.
- Est time: <1 minute per preview.
- Export your chosen design as an STL file (triangulated mesh).
- Est time: ~10 minutes per export.
- Outputs with checkmarks indicate previously exported outputs.
- Slice the exported file with your preferred slicer and print immediately.
