Bridging Bridging refers to a 3D printer's ability to print material across open spaces without support structures. During bridging, filament is extruded in mid-air between two anchored points, solidifying quickly to maintain its shape. Successful bridging depends on factors like print speed, cooling, and material properties. PLA, for example, is well-suited for bridging due to its quick cooling. Poor bridging can result in sagging or stringing, but optimizing slicer settings like fan speed and travel speed can improve results. Bridging is critical for designs that include features like holes, gaps, or overhangs. |
