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?
