Poor BridgingUpdated 7 months ago

Bridging in 3D printing is the ability of a printer to span a gap between two points without any support from below. Common signs of poor bridging include sagging or drooping strands across gaps, stringy or incomplete fill on the underside of bridges, and excess material or blobs on the edges of a bridge. These issues can stem from several factors, such as incorrect printer settings, inadequate cooling, or the physical properties of the filament. Please follow the instructions below to fix this:

Adjust Print Speed and Flow for Bridges

Slow down the print speed when bridging. This gives the filament more time to cool and solidify after being deposited. Additionally, reducing the flow rate slightly can prevent excess filament from weighing down the bridge.

Optimize Cooling

Good cooling is essential for successful bridging. Increase the cooling fan speed to help the extruded filament cool and solidify more quickly.

Implement Supports When Necessary

While the goal of bridging is to eliminate the need for supports, in some cases, adding minimal support structures can help achieve cleaner bridges, especially for very long or wide gaps. Refer to our [Technical Data Sheet] for recommended overhang angle thresholds.

Use the Right Material

Some materials are better at bridging than others. PLA tends to perform well because it cools and solidifies quickly. Materials like ABS and PETG, which are more prone to sagging due to slower cooling, might require more fine-tuning of printer settings.
