Extra Nozzle Space in UM2

Hello all,

What if the hole for the extra nozzle in UM2 was removed, as there will be no dual extrusion? This would allow the fans to be closer to the nozzle and increase bridging and overhangs, especially on the right side. Also a lighter printhead could move faster. Just an idea.

Cheers

    You are right, but not sure it's worth the trouble, though you may be able to shave some weight of the main metal parts.

    To get the more even fan flow the solution is already here, my advice, print it in green-tec;

    Makes sense.

    The green-tec has enough stability under high temperatures to not warp as a fan shroud? Would it be worth milling it from aluminium? What about making a carbon fiber fan shroud?

    The greentec is a very good filament!! Make sure you have a good first layer and 60 degrees printbed, and the rest is easy. Very high temp resistant.

    For a fancap, even if it resists 100C try to cover the hottest areas with hihgemp aluminium tape. It will give you much more months of use, specially to avoid deformation due fan weight or high speed moves. A 150C alu tape is cheap and works fantastically.

    For Pla-tec bed temp is 55C. For greentec is important to use hairspray to avoid adhesion issues. pla and greentec are almost the same but platec is slightly more rigid and greentec is slightly more flexible.
