Description

I worked to keep these as thin and light as possible + the best fuzziness/time balance.

Choose smooth sides if you intend to tile them, or all-fuzzy for singles.

The template is included if you would like to change anything go for it.

These can not dampen sound. Only diffract it. So the echo in your room will get a nicer tone if you have MANY of these. But it will not get quieter. You need soft, thick material like foam to actually dampen sound. These panels here are more decoration without actual usefulness I would say.

I would love to have someone do some real testing. I got a good reduction overall but I printed with thin walls and lots of fuzzy.

@kungpaoshizi

Any surface will dampen sound as the laws of thermodynamics clearly dictates diminishing returns from input post-reflection/refraction. More ridges would do better with higher peak to trough configurations. Foam is substantially better, but you could mimic foams cellular structure easily. I would be interested to see how a barnacle structure would fare.

I was thinking the same thing. This will cause some reflection, not absorption. Dampening will be marginal at best.

adds a nice aesthetic to the office. more art than function but still nice.

Audio guy here, the others are correct. This is will give you the visual of the actual tiles without the utility that most are looking for when typically looking into something like this. PLA (Polylactic Acid) filament is commonly used in 3D printing for a variety of applications, but it is generally not considered an ideal material for sound dampening or acoustic treatment. Sound dampening materials usually have specific properties, such as a high density and the ability to absorb or diffuse sound waves, which PLA does not naturally possess. Here are a few reasons why PLA may not be the best choice for sound dampening: Density and Porosity: Effective sound-dampening materials tend to be dense and/or porous to trap and absorb sound waves. PLA is relatively lightweight and solid, and it may even reflect sound to some degree. Rigidity: PLA is a rigid material, which might cause sound waves to bounce off rather than be absorbed. Cost: Depending on the scale of your project, 3D printing large PLA squares could become costly and time-consuming. Environmental Factors: PLA is sensitive to heat and humidity, which might limit its use in certain environments without additional treatment. Alternative materials that are often used for sound dampening include acoustic foam, fiberglass, mineral wool, and mass-loaded vinyl. These materials are specifically designed to either absorb or diffuse sound energy, making them more effective at noise reduction. If you're interested in a DIY approach and want to stick with 3D printing, you might explore filaments that are specifically designed for sound absorption or experiment with infill patterns and densities to see if they provide better acoustic properties. However, for a professional sound-damping solution, it's generally best to use materials specifically engineered for that purpose.

Good info, what do you think about TPU?

@TrTpTd

Thanks, ChatGPT.

@brandonharvey

Replying to @TrTpTd :

Thanks, person who adds nothing to the conversation. TPU will give you marginally better results when you compare it to the utility of something that isn't, by nature, a good fit for what you're hoping it will do. Visually sure, it looks like something you've seen that uses a vastly different material that performs a particular function. I don't think anybody has an issue with anybody sharing a model, I feel like most of us are just trying to drop enough hints that if somebody is coming here and thinking of printing a bunch of these to magically transform a space into some studio grade spot that sounds much better as a result of using these, that's not the reality most will experience.

Fun print!

Looks cool and was a fun print!

would like to have a lower material usage pls

@Fredwood

Hello Mark Jing, thank you for your feedback. I have created a new print profile with reduced material usage. It is named "Low Material, All-Fuzzy, 0.24mm Layer, 2 Walls, 0% Infill." Best wishes, Fredwood6000✌️

@just.gil

There's dampening and there's diffusing. This is not dampening (based on the title). To dampen (make quite), you need dense sponge-like material. Diffusing, whish seems more like what this design is for, is to scatter the sound so it won't echo as much in a room, but it doesn't dampen the sound.

The designer has replied

@TripleGWorkshop

I didn't have any equipment, but I put these under my printer and it seemed to both diffuse and dampen the sound. I printed with single perimeter, lots of fuzz, and minimal infill to hopefully let that sound absorb. I noticed a sharp drop in overall noise laying these under the printer where it seemed to help keep sounds from reflecting back up.

@rjakiel

What did you print these in? Wondering if they would be worthwhile to print in TPU or Flexible PLA with less fuzziness? Thought process is the softer material allowing for more sound dapening.

The designer has replied

@TripleGWorkshop

I did PLA but I think TPU would be even better
