How far can a 3d printer 'bridge'???

How far can the Creality Ender 3 or CR10 Bridge? In this video we will find out. Bridging is possible because of the tensile strength of the filament. As long as the extruder is "pulling" the filament the 3d printer can print horizontally in mid-air.

That's incredible. I'd never have expected it to work that well. For some of those bridges, you need only add a couple of mm extra material underneath and you could sand it down after do get a nice part

"wow bridging is amazing!!"
*people with stringing issues*
*visible confusion*

Try a dual-fan set up. You’ll get significantly better results!

I also find print orientation plays a part in bridging if you're using a single part cooling fan, because of where the fan is compared to the direction you're bridging. You should try rotating the parts 90 degrees and run the test again with the same settings.

I have an Ender 3 Max, and I had no idea it was capable of bridging so far. Nice to know I made a good purchase for my first 3d printer.

What about reducing the flow to get more tension on the string that you're pulling to the other side 🤔

Go from the bottem left to the top right

Quick and edited for results. Quite well don

My resin printer will bridge about 9 mm before failing :thumbsup:

I think generally anytime we're doing bridging like this you would normally use a couple of really small supports

While Im waiting for the 3D printer delivery, Im watching videos like yours. Here Im very surprised about the quality of the writing ! Very cool !

This man is removing prints from the build plate WHILE it's still going.
That's amazing.

[wissamphysics]

I never thought that was even possible!!, , well done

Dude, filament choice and cooling matters too, you need to put what filament and settings you have.

[zeekjones]

Since it does straighten out, eventually bridging well at the top, you can have a sacrificial amount based off estimated sag.
I would only use this at the very top of builds, as closer to the bed a more standard support lattice would be more economical than accounting for sag to straighten out.
You're going to spend a little extra on structure somewhere, more often though standard support will spend less.

This certainly answered my question. I wondered how you could print a side with a square hole without a support. This really puts standards to my designs! THANK YOU!!! <liked.subscribed.saved=True>

Idk what the music is on this video, but it had my walls rattling. Fantastic.

If you blew cold air on the first overhang passes, I'm willing to bet you could get better results on the longer bridges. Would be interesting to see if PTFE filament could print supports that would break away cleaner and easier as Teflon is known for keeping things from sticking.

[CornerCamper]

It would be neat to see a video with some supports drawn in halfway through or at some increments to help with longer bridges

The way each strand is separated is actually cool
