3D Modeling CAD Design Split Model Testing

Split Model Testing

Split model tests help you to test specific parts of a prototype. They focus on a small area of an overall design in order to save time and material. Split model tests are especially powerful when you have a CAD model, which can easily be divided into small-scale exploratory models.

Identify a specific part of a design that you'd like to experiment with.

​​Step 1

Focusing only on your chosen area, design several small-scale models to test.

​​Step 2

Make and test your small scale models. Move forward with the most promising design or create additional split models based on your testing.

Step 3

If your model is very large, you can shrink the size.

Scaled down

This split testing method is great for pieces that needs to fit into each other.

Example: Fidget Spinner

The center ball bearing measures 22mm

Print several holes with various diameters to test which the bearing fits into it best.

​Lower Print Quality

​There are several ways you can lower the print quality in Bambu Studio.

- lower the wall/perimeter count (faster print time and less material)

- increase the layer height
(faster print time but about the same material)

- lower the infill percentage
(faster print time and less material
