Fungus sound absorbers?

[Pano]

Will we have 3D printed fungus sound absorbers next? Fraunhoffer think so.
Fungus as a sound absorber

 

[tsmith1315]

At no point in my life have I ever thought I'd hear the term "printed fungus".

Did you have natural fungus absorbers in your cave, Pano?

 

[Pano]

Ha ha. Oddly no. Fungus apparently do need some light to grow, and there was none down there when the lights weren't on. I looked into mushroom farming down there, of course.

So if this fungus is self propagating, what do you load the printer with?

I wonder whether this turns out to be durable with time and humidity.

 

[Pano]

Both good questions. We make sound deadening out of animal and plat fibers - wood, wool and cotton. Perhaps fungi are next.

Anyone think fungus spores are healthier than mineral fibers?

 

[turk 182]

in current times it's controversial to say that health matters at all...

It looks like they mix straw, wood, "food waste" and fungal fibers into the printer. Once printed, the fungus grows throughout the... (matrix?) to solidify it. Then, it's kiln-dried to kill the fungus.

I share your concern, especially with humidity. Seems like it would readily absorb moisture from the air and help other tiny organisms propagate when trapped in the porous structure.

Still, it's pretty neat.

 

[Pano]

Do you think it would absorb more than vegetable or animal fibers? Seems like it would be more porous.

 

[tsmith1315]

Their description of long-stranded hyphae and open cell walls sounds pretty porous. I guess if it's open enough, moisture will get out as easily as it gets in.

Perhaps it's prejudice, the phrase "straw, wood and waste from food production" just sounds like something that would tend to stay moist. It's curious, I'd like to see it.

3d printed fungi? As sound absorbers? Life must be one damn thing after another for these unfortunate eukaryotics.

Hi pano. Similar concept as moss painting. Take moss and yogourt and put in the blender, then paint it on whatever substrate you desire.. BOOM!! moss wall! LoL
*moss likes natural granite type stone best, even though slightly radioactive.

 

[Pano]

Do you mean the moss will take hold and grow on the wall? Does the yogurt help it establish a foothold?

 

[Top Shelf]

Yes and yes.

In regards to mushrooms, what do you call a mushroom with a 10" pecker?


A funguy.

I have in the distant past taken fungus which had a dramatic affect upon the music I later listened to. All very interesting.
