GENERATING BINARY TREE SUPPORT STRUCTURES IN 2D

GENERATING BINARY TREE SUPPORT STRUCTURES IN 2D

The Final2D function is designed to determine and mark support points for a 3D structure, such as an F-shaped structure, by analyzing its geometry and identifying points that need additional structural support during 3D printing. The method employed by Final2D uses the concept of a **binary tree** for its efficient division and processing of space, ensuring that only necessary supports are added, which optimizes both material use and print time.

Key Aspects of Binary Tree Support Placement in Final2D:

1. Recursive Division of Space:

The binary tree approach recursively divides the structure's space, focusing on areas that require support, and marking points that need reinforcement based on spatial parameters, like overhanging features.

2. Efficient Support Placement:

By using a binary tree, Final2D can efficiently isolate regions that are prone to deformation or unsupported spans. This precision helps in reducing the number of supports needed, ensuring minimal interference with the actual model geometry while maintaining structural integrity.

3. Adaptive Sampling for Optimal Coverage:

The function adaptively samples the space, assessing each region's need for support based on the angle of slopes or the presence of gaps. It helps detect potential issues due to overhangs or cantilevers that might deform or warp without adequate support.

4. Material and Print Optimization:

Using binary tree support placement allows Final2D to minimize excess material usage by adding supports only where strictly necessary. This not only conserves material but also decreases print time and post-processing requirements, enhancing efficiency.
