I saw a user in a forum asking for help with bridging. They were trying to create a large print that had many bridging features that were intended to be straight across and ended up being droopy.

When someone asked what they had done already, they responded with “I slowed down my speed to help the bridging out.” In most cases, this is the opposite of what needs to happen. If my print has a lot of bridging features I typically speed it up. If you think about the mechanics of what is happening here, heat is being applied the entire time that your nozzle is extruding. So, the longer something takes with heat being applied to it, the more it will sag as a result.
