3D Wave Acoustic Panel

When moving into our brand-new offices this summer, we had for the first time big spaces that we could dedicate to team meeting rooms. 

We quickly faced the issue of sound reverb and decided to design some acoustic panels using our own Fab CNC to both improve acoustic and embellish our room. You'll find all instructions and G-code hereby to make them yourself, as well as the Fusion360 project if you want to make modifications. 

The panels are 540x1008mm, and we made them in 30mm MDF.

First we need to clear a maximum of material using a roughing bit, to get as close as possible to the shape of the 3D waves.

• Use the G-code Acoustic Panel Parallel 32.15mm.nc
• Use a BRAVO 8mm end-mill (available in our Ultimate set)
• Place your XY0 coordinates in the center of the part
• Set the Z0 on the spoilerboard. Then add +2.15mm of offset to it. 

We can now use a ball nose end mill to smooth out the 3D shape using a parallel operation. It is a long operation as it has to do a lot of narrow passes, but it can run pretty fast as it removes very few material thanks to the clearing operations.

• Use the G-code Acoustic Panel Parallel 32.15mm ZETA ONLY.nc
• Use a ZETA 3D conical end mill ( also available in our Ultimate set)
• Place your XY0 coordinates in the center of the part
• Set Z0 on the spoilerboard then add +2.15mm of offset to it.

Last thing to do is to cut the contour of the parts to free them from the stock panel.

• Use the G-code Acoustic Panel Contour 30mm.nc
• Use a BRAVO 8mm end-mill (available in our Ultimate set)
• Place your XY0 coordinates in the center of the part
• Set Z0 on the spoilerboard. (No additional offset here).
