K-factor in 3D Printing K-factor, commonly used in sheet metal bending, also applies to 3D printing as a measurement of material behavior under stress, particularly for flexible or thin-walled prints. It helps predict how materials deform, allowing users to compensate for potential warping or shrinkage. In additive manufacturing, adjusting the K-factor in slicer settings ensures accurate dimensions when printing parts that need precise fitment. Certain filaments, such as TPU or nylon, exhibit significant deformation, making K-factor adjustments essential for functional prototypes. Understanding K-factor is particularly useful for engineering applications where mechanical performance and dimensional accuracy are critical. |
