5 Solutions for Flawless Bridging!

Bridging, in the world of 3D printing, is the magic of creating a horizontal span of material between two elevated points. Sometimes, though, they don’t quite stretch as beautifully horizontal as we’d like. During my technology escapades, I faced some challenges with not-so-perfect bridging, and I knew I wasn’t alone. So, here’s my handcrafted guide for those looking to tackle this issue.


The golden ticket to rectifying shoddy bridging? Enhance your cooling mechanism by integrating a superior fan or cooling duct. Additionally, consider reducing both your printing velocity and temperature. This gives the filament ample time to chill as it dances in the air. Beware of over-extrusion; it’s not your friend in this battle! Adjust your flow rates accordingly.

The Mystery of Inadequate Bridging in 3D Prints
Bridging hitches often arise when adventurers in 3D printing dare to manifest parts of a design without foundational support underneath. This act is akin to ‘bridging’, particularly when attempting to print smaller designs without adding support. This, while saving on time and material, occasionally results in bridging hiccups, as the filament strands might drift away from their intended course. But fret not, for with the right strategies, such issues are but minor blips in our 3D printing journey.

Triggers for Bridging Troubles:
– Insufficient Cooling Leading to Delayed Solidification
– Excessive Flow Rates
– Ultra-fast Printing Speeds
– Overly High Printing Temperatures
– Attempting Extended Bridges sans Support

Unraveling Bridging Hiccups in 3D Prints:
Achieving a print that mirrors its design is the dream. Even the slightest deviation can toss in a spanner, consuming both time and energy. Pinpointing and addressing the cause ensures not only the beauty but also the precision of your creations.

1. Boost Cooling or Fan Momentum: A quick fix to ward off bridging woes is to crank up the fan speed. Ensuring efficient cooling is pivotal to preventing filament sag. Ensure your cooling fan is in top shape. Post the initial layers, let your cooling fan flaunt its highest speeds and witness the bridging marvels! However, remember to monitor and balance, as excessive cooling might introduce other predicaments.

2. Diminish Flow Intensity: An overzealous filament flow could amplify bridging challenges. Regulating this will facilitate quicker cooling. A flow calibration tower might be your best tool here. But, ensure you’re in the Goldilocks zone; neither too fast nor too slow.

3. Reduce Print Speed: Rapid printing can sometimes be the culprit. Slowing things down might just allow the filament to cozy up to the preceding layer. Explore the optimal speed with a speed calibration tower.

4. Regulate Print Temperature: The right temperature can make all the difference. For popular filament types like PLA, the sweet spot typically lies between 180-220°C. However, ensure it’s not too low, or you might face other challenges.

5. Incorporate Supports in Your Creation: If all else fails, or if you’re attempting extensive bridges, introducing supports is a sure-shot way to perfection. They not only enhance the structural integrity but also elevate the aesthetic appeal of your prints. Ensure they’re designed for easy post-print removal.
