True or False: A raft must be modeled in the CAD model before sending the file to the slicer program.

True or False: A raft must be modeled in the CAD model before sending the file to the slicer program.

• A. True
• B. False
• C. Only necessary for large prints
• D. It depends on the material used

Answer: (B)

The statement is false because a raft does not need to be modeled in CAD before importing it into a slicer program. Rafts are typically added as part of the slicing process, allowing users to select various settings and structures to optimize print adhesion and stability without altering their original CAD models. When preparing for 3D printing, the responsibility of generating support structures like rafts is typically delegated to the slicer software, which can evaluate the specific requirements based on the model geometry, size, and other factors. This flexibility enables users to maintain a clean design in the CAD file, focusing on the part's intended geometry rather than additional structures that the slicer can handle automatically. Consequently, the inclusion of rafts is a feature within the slicing software rather than a prerequisite for the CAD model itself.
