I wonder about a breathable pegboard box lined with acoustic foam or something like that...
Tried it, didn't help much, I used the sound foam we use in the Gen bays. A muffler on it's intake might help. I have some small ones for the air compressors on the buses. Might be something 3D printable. If you plug the input hole it quiets right down
Sound foam mostly works on ringing high frequencies(we sell it at work if you want to play with some). when sound proofing a house, (or similar concept for a box?) you would sandwich a thin sheet of rubber between two off set drywall sheets(or sometimes just 2 layers of drywall). rubber absorbs vibration and prevents it being transmitted to the next surface. Similar type of concept they used to use in car audio contests to prevent panel vibrations. Or you could try something like thick acrylic and then air muffler/ baffles on the the holes essentially containing the sound and then controlling the output. another way might be a vacuum chamber but that might be a bit far fetched. We have most of these materials for sale at work if anybody is interested in messing around.
Add to that active phase cancellation:

Is there a way that we can add a silencer to the printer? Do you have any other solution to remove the noise generated by the printer?
There are a lot of ways to contain or remove sound, but if it's literally just the fan like Bee said replace the fan? I can't help but think there is probably a market for a silent printer, they do get noisy especially in multiples like classrooms and makerspaces.

was the contest rigged? seems like there was somewhat a lack of imagination in the 1st place entry. You should have included the stone tablets with the commandment:"thou shalt not predetermine contest winners", lol Any way, nice work , it looks very professional in the photos.

I was thinking more along the lines of picking up a 200 dollar laser "cutter" off of banggood. I don't want to mess with the chemicals if i can find a way around it. You'll have to show me how you do it, i don't envision a cnc cutting super thin copper ending well?

I found this to be pretty interesting. I wonder however if there is risk in the reflections damaging the lens. I can get shim Steele like this at work, and acrylic is cheap....
