3D Printed Sound Treatment

Is anyone using 3D printing to make sound treatment products? A buddy of mine has a 3D printer that can make objects 18”x18”x18”. I’m interested in making quadratic diffuser panels, especially because their intricate construction is rendered very simple with the use of 3D printing. (Google image search “quadratic diffuser panels” if you aren’t sure what they look like). Professionally made panels can go for hundreds of dollars. This seems like a cost effective approach to sound treatment. It’s got me wondering, though, if these panels need to be made of something sturdier than plastic. I could always back them with Dynamat or a block of wood if that would help.

What are your thoughts?

Interesting. So what do you think would be best with the 3D printed “block” quadratic diffuser:
1) “Solid” infill
2) Hatched infill 
2) Hollow infill with a dampener like dynamat on the back sides of the blocks
3) Solid infill with a flat back and attached to a block of wood or other substrate. 

I’m thinking of putting these diffuser panels in the center and behind the speakers because I’ve seem many a fancy setup do this (they must have a good reason 🙂) and because it gives you something interesting to look at while listening as opposed to a wall or flat absorbent sound panels.
