To truly enable unrestricted multi-material printing, Luban has introduced the interlocking structure, which detects the presence of two unlike, unbondable materials and generates a mechanical interlocking structure. With this feature, you can make the most use of the characteristics of the two different materials. For example, CPE and TPU95A. CPE is a rigid material while TPU is more flexible.
The idea behind interlocking structures is Luban will generate interlocking beam structures at the location where two models touch. As you can see in the image, it is much like overlaying two different infill patterns. This improves the adhesion between the models, especially if the models were printed in different materials.
You can read more about this feature in this video: Examples for generating interlocking structure.

To enable interlocking structure, go to Parameters > Initial Layer Adhesion > Generate Interlocking Structure.
¶ Interlocking Beam Width
The width of the interlocking structure beams.
It should be set as a multiple of the Outer Wall Line Width.
¶ Interlocking Structure Orientation
The angle between the interlocking structure beams.
¶ Interlocking Beam Layer Count
The height of the beams of the interlocking structure, measured in number of layers. Less layers is stronger, but more prone to defects.
¶ Interlocking Depth
The distance from the boundary between models to generate interlocking structure, measured in cells. Too few cells will result in poor adhesion.
¶ Interlocking Boundary/Avoidance
The distance from the outside of a model where interlocking structures will not be generated, measured in cells.
