Why it matters: A smooth, well-adhered first layer ensures stability, accuracy, and prevents costly mid-print failures. Common culprits: Dirty build plates, incorrect Z-offset, poor bed leveling, or ...

When slicing a model for 3D printing, the part is divided into a stack of flat, 2D layers. But there’s an alternative in the form of non-planar slicing, where the layers can follow 3D curves. [Rene K.

Design is the only real limitation.
