What is the functionality of a BASS support structure?

A BASS support structure is designed to provide temporary support to overhangs and complex geometries during the 3D printing process. This type of support material is used in conjunction with the primary build material, and its purpose is to ensure that the model can be successfully printed without collapsing or failing due to lack of structural integrity in unsupported areas.

The key characteristic of BASS support structures is that they are meant to be removed after the printing process is completed. This allows for a clean final product that only retains the main features of the model, without any unnecessary or permanent additions that could detract from its appearance or functionality. The support material can be manually or easily broken away, leaving behind a smooth surface for the finished piece.

In contrast, other options suggest that the support is either a permanent part of the model, made from durable materials that stay attached, or dissolve over time, which does not align with the typical use and functionality of BASS support structures in 3D printing. Permanently attached supports would defeat the purpose of improving the aesthetics and usability of the final model, while materials that disintegrate on their own would not serve as effective supports during the printing process.
