Hi Printers
i have a new blue one RBX1 (sorry for my bad english)
My wife is not very happy with it. When i print something it makes horroble loud noises. No bad sounding sounds but loud! The fans are extremely loud. Why must on the left side of the top fan another fan inside makes such a noise….i know some other printers they are silent! I know silent is relative, but the rbx 1 is loud! i get another device from my dealer, but it is loud too….is there a possibility to make it silent???? or more silent????
a 1000 bucks printer and its a helicopter in my room - wonderful ;-(
Please help…all other printers work with an passive DC…why must the rbx1 have so such loud fans???
or did i have take some configs wrong!?That is by design. Other printers do not have closed chambers and/or not try to keep the temperature from building up too high. I’ve switched to PLA from ABS yesterday and general ambient temperature for it is lower - which caused my Robox to start screaming - fans went to full speed.
My understanding is that it helps quality of print: lower temperature of ambient (lets say ~30ºC) helps PLA cooling down sooner and producing better quality prints. Other printers (the one you’re referring to) usually do not have closed chambers and are relying on ambient of the room they are in to be sufficiently low temperature. Or have different type of chambers and types of cooling.
So, it is a feature - not a issue with the printer. I’m pretty sure others will expand on it, too…
IT Sounds very useful
From this side i didn’t See it
Tanks for your feedback
Yes, this printer is not exactly quiet… I too was (badly) surprised as I used it the first time. I wasn’t expecting a “vacuum cleaner sound” from a pro/consumer 3D printer at all.
I’m wondering if exchanging the original fans with more expensive silent ones (arctic cooling) could help. But I prefer not to void my warranty. I must say I stopped asking questions directed to CEL on this forum, because of the lack of reaction. I don’t think it’s a very high priority, because there is still so much work to do on the software side…@thejudges make sure the printer is not sitting on something that rattles or has a high sound transmisivity, also you could get some anti-vibration pads to place under your unit. I am currently using 2 foam puzzle mats about 1.5in total under mine and it masks the sound somewhat less noticeable from afar. This suggestion will help just a bit so that you hear it less in other rooms but it won’t take the noise completely away.
MohI don’t find the fans on mine intrusive when printing, they don’t seem any noisier than the pc that’s stood next to the unit. The only time they get loud is when you select the cool down and unlock door setting, then they ramp up to full chat for a minute or two until the machine cools down.
The noisiest part of mine appears to be the drive motors, there seems to be some vibration from the machine when both the bed and head motors drive in a particular direction. I was banned from running prints overnight because it could be heard upstairs, however I’ve since found that if I turn the speed down to 0.5 at night its a lot quieter and cannot be heard upstairs.@muttleysdad the .5 speed adjustment at night is a great tip, i will give it a try also, like you I have been banned also, glad I am not the only one driving the wife crazy lol =)
MohLoudness of fans depend of material and ambient temperature. If you’re printing PLA and ambient temperature is set to 30ºC - there’s good chance fans will start screaming relatively soon. With ABS and 55ºC they’ll probably be no louder than normal PC.
But it is now - during winter here. Let’s see what it is going to be like when room temperatures start reaching 25-30ºC… Especially with PLA.
Slowing it down definitively lowers the amount of noise… and prolongs print times (increases quality?).
There is a resonance with the motors on some shapes that can be tuned out with little speed adjustments, faster sometimes stops the resonance.
At home my desk is a wooden box, basically an amplifier. At work it prints beside me on the desk all day everyday and I barely notice it. Fan noise is lower than motor noise.
If you fans are really noisy, power off and check that they are not hitting the grill, you can easily bend the fan grill away from the fan blades on the ambient fan (top right inside the build chamber).
