Infill percentage experiment for 3D printed speaker cabinets

[Bryguy]

I don't see that this has been posted anywhere so sorry if this is a repeat post

The construction acts much like a constrained layer. He is testing to see which infill percent has the best “jam
characteristics.

The box is also poorly braced.

How easynis it to change the infill geometry?

Quite easy, at least that's what my brother said, who does 3D printing. He was kinda surprised he used a square infill pattern

It's typically a selection of predetermined patterns with a selectable fill factor. This way managing an otherwise solid part of the build becomes the job of the slicer. It doesn't have to be this way but it's much easier.

He used square infill probably because it takes a lot less time than gyroid which is one of the strongest

The gyroid, as it has an open structure, can be used to fill the enclosure volume. That way it breaks up resonance patterns, reducing the need for internal damping. This is an interesting case for that.

thank you never saw this study!

Thanks for the link,
Excellent

I would also like to say, the bit about I-Beams is important & succinct.
