I am new to 3d printing. Posted a picture of a calibration test in a fb group and was told my problem could be solved by getting part cooling on both sides of the nozzle.
Can I just start measuring and designing a fan duct to redirect part of the airflow to the other side of the nozzle, or are there risks attached to that?
PLA tends to warp on overhangs due to the lack of cooling on one side of my print. i mitigate this with a desk fan but a new fan duct would be really great to cool from both sides. A new fan duct might be difficult to model but that would be much appreciated.
That one still does not include more sophisticated things like a ring outlet for the air or two outlets at an angle that eliminate the “dead” zone on the opposite side of the hotend, and it is not perfect since the fan placement will let the hotends collide with the side windows, but it is a start and might be a good basis for further ideas.
Im at Work, I started today, finished in 2 days at my customer here. Than I will make a picture of them. The 2 5015 blows very much Air down, the 1 fan duct is straight down and the other from Fan in the back is more on the side, so he blows more on the side down. I have to go down mit the normal cooling speed to 85% for PLA.
It would be cool to see a fan duct that allows cooling from both sides of the part. The cooling is absolutely sufficient but only from one side from what i’ve seen PLA is warping at high speeds because it cant get cooled enough
Yeah you need modified a little and cut off one fixing hole from the fan. But that thing works.
If you need I can send you more informations. By the way, for the right extruder you have to mirror the part on x and y. Depends on your position on plate. If you don’t mirror 2 axles the fan are to close to the bracket on the rear
and you see i dont print on the glass, lokbuild is way better, no matter what you print, pla or whatever. all stick good on the lokbuild. no warping
Did anyone has activated the jerk Funktion in Luban and what settings you use? You let jerk (if activated) always on or not?
Only on low speed or doesn’t matter
The Original Cooling Fan for the Filament is a Funny thing. To small for that speed and Temps.
The Blades of them are to big and cheap, dont have much Airflow. I dont understand why they dont put better and bigger ones into a Printer on that Price Class
That was the Original ones. You see the big blades.
I do not wonder why everyone have cooling Problems.
I try that Toyfans outside and they have really not much Air flow
So I put on 4x 5015 and it is way better.
These blades behind the decorative cover looks good but for real good prints at high temp and speed they are much to small, they cant cool the filament fast enough down for bridges and on corners or on smaller Parts of the Print
