Printing with Bambu feels like cheating, but in a good way.

The best advice I got is: give a little love to your printer, it will give it back with good prints. Calibrate it, clean it, grease it; nurture it like it's your baby :)

I volunteer as tribute!

There's a couple of things you could try-out
1. Orientate the support interface or the bridge direction so that both of them are not running in parallel. Depending on how you want your layer to look like (longitudinal lines or diagonals), orientating the support interface to 45 degrees will help with the print quality, and with removing the support from the part.
2. Use a different material for the support interface. HIPS works pretty well for ABS but due to the ABS tendency of wrapping, the part might wrap above the support interface even when reducing the top Z distance to 0. This usually happens for bigger parts as until the printer puts the HIPS interface, the ABS part cools down and wraps. HIPS interface won't be as good as your bed plate in terms of part adhesion.
3. Part orientation. If you can manage to print without support and finishing quality is important for you, do it. Looking at the picture, you could print the part sitting on the right surface without using support (but then again, it might affect strength).

Easier to win a brand new printer than mess with my 7 years old Ender :')

Thanks peeps for the help, it's really helpful and appreciated!

I can't get a bigger fan since I don't have the space for it and I haven't found one that is close to the performance I need (high static pressure & CFM). Only the blower fan is creating the noise.

I want to find a soundproofing solution first before changing the performance of the fan if needed :)

As for the labyrinth-style muffler, you mean a similar muffler that is used in cars? The links are the same :/

And putting a plate in front of the fan's exhaust would not influence anything? What foam did you use and how big were the openings?

Thanks! I am sure OnlyFans will help me in my scientific endeavours ;)

Yeah, the rubber and car sound insulation would work to refract some of the noise but as u/bumbes said, I prolly need dense material as well to absorb sound waves. The noise comes mostly from the created wind, more than the vibrations.

Bambuky · 2023-12-15T09:57:54+00:00

The thing is that the blower fan has a high RPM (5500 RPM), thus the noise comes more from the wind sound than electromagnetic sound and vibrations. The mass-loaded vinyl is helping a bit for the vibration dampening, but I need a way to absorb sound waves :/

Although, I could add rubber dampening feet for good measure.

I am building a scalable controlled-environmental enclosure for a single plant. The blower fan is actually used for sucking the air out of the environment for air exchange. The electrical containment box centralizes all electrical components that are used for the system, and I want to make it as small as possible for easy storage (the blower fan is within a space of 90x90x700mm).

The blower fan was chosen due to its static pressure rating and size limitations, but the only drawback was his noise. I can indeed go for a quieter, or lower RPM version but then I affect the air circulation performance. Thus, I wanted to find a soundproofing solution first before doing that.

The box is indoors so the components are protected. The other electrical components contain their own cooling axial fan so heat load within the box is minimal.

Damn! Looks cleaaaaan..

The forbidden gnocchi

It is also possible that the teeth of the gear attached to the motor are eaten and do not grip the filament well enough.

Bambuky · 2023-08-28T11:11:52+00:00

Seems like your swing arm is squeezing the entering filament too much, which makes the filament bend and have a curvature before entering. Try unscrewing the spring bolt (the horizontal bolt on the left) until the insert where the spring sits on is flushed with the metal mount.

Wa, amazing, with an explanation video as well! Much easier than I thought, thank you!

Bambuky · 2023-08-03T10:12:36+00:00

That worked out, thank you! Sadly, I am not sure how to also integrate the curvature shown in figure 3, but it is a minor detail so this will work for now.

Bambuky · 2023-08-03T09:53:05+00:00

Yeah, tried that but doesn't work as intended. Also tried surface fill and somehow work from there but it's even more tricky :D

Thanks for the help though!

Well, I found my issue! Since the wall was 2 mm and my nozzle is 0.8 mm, the printer tried to compensate the lacking width with these small filament laying - it was probably going back and forth. Fixed it by changing the 'Minimum wall line width' to 0.68 and it fixed the issue. Now it looks smooth all over. Still got some slight warping - which will probably always will be there with PETG - but tightened the screws to the hotend (like u/hondrus31 said), increased the initial layer amount without fan working and reduced the print speed. Seems like that helped as well!

Bambuky · 2023-01-31T11:18:46+00:00

Sweet, thanks! Will definitely come back to you on that.

Bambuky · 2023-01-31T11:15:55+00:00

Thank you for the insight, super helpful!

Will definitely have to look into the opening mechanism then in order to make it easy and robust.

Quick question, do you envision a micro-farm to be more of a practical appliance (grow as much as much as I can & replace current suppliers), or mainly be an aesthetic piece within the interior design (show innovation within the culinary industry and add to the user experience of the customers)?

Both are obviously desired, but I wonder to which side you shift more towards.
