Progressive Overhang Cooling Test (10°–80°)

Progressive Overhang Cooling Test is a vertical calibration model designed to evaluate part cooling effectiveness across a wide range of overhang angles, from 10° to 80°. The continuous curved geometry makes cooling limitations clearly visible, allowing users to identify the exact angle at which surface quality and layer stability begin to degrade. This model is ideal for testing and comparing cooling performance, fan efficiency, and slicer cooling settings under real printing conditions, across different materials and profiles. Angle markers are embedded directly into the model for immediate visual reference.
