Example of a very long bridge...

The part is a safety cover for a handle that pulls the hinge pins from the cargo door of a light aircraft.

The narrow bridge is 1", the wide one is 3".

The only problem was at the leading edge of the wide opening - I had too much of a radius along that edge.

ive been waiting to see this...Damn impressive!!! Now I want to try it...

I didn't know you could do bridges that wide without support. I had to watch that one twice.

Thanks. I used the current release of Slic3r on it. The squirrel cage fan & special duct makes it happen - no air hits the hot end to cool it.

Wow, that's impressive!

[Navkram]

great job, can you post slicer settings

[foshon]

You'll need more then his settings, Gene "The mean printing machine" has that machine dialed in. Nice work Gene!

I'll try to post the preamble section from the gcode file this week. There's nothing special about it, honest!

That is great bridge that you did, i think that the secret is in the blower, it blow so much air that as the pla got out from the nozzle it's almost immediately get cold and hard, so the bridge get so nice

[geneb]

Yep. Guanu @ SeeMeCNC designed the duct. Works fantastic and it doesn't impact the hot end temperature AT ALL.

Does that fit the 30x10 sold on the SMCNC site?

[guanu]

I've been working on the design for the new platform coming out soon..

Will the platform include the fan shroud?
