The Laser Absorbent Panel is a digital manufacturing solution to reduce the reverberation of a room.
Because we only recommend the best absorbent materials our absorbent panels are two times more efficient than standard foams at low frequencies
Milimetric precision enables to create perfect puzzle-like pieces which then can be easily assembled.
All necessary materials for less than 20€
All you need is, mdf boards, fabric canvas, white glue, scissors, glue gun and Rockwool or fiberglass, and if you are in Europe you can also use a recycled fabric material called Geopannel
It's very easy, you're gonna be fine ;)
The Laser Absorbent Panel is a digital manufacturing solution to reduce the reverberation of a room. Absorbent panels are the first acoustic elements we introduce in a recording or control room.
Download this CAD v1.4.4 file and take it to a laser machine. You can find a local laser machine using the Fabhub site or the yellow pages. If you live next to a FabLab you can contact them to know when there is an open day.
Test your dimensions & material specifications. When we use .dxf files, not all software maintain original dimensions. When original dimensions have changed we need to rescale the .dxf file to the original size. We provide a diagram so you know you are on the right track.(Don't worry if you are not familiar with cad files, the person with the Laser Machine will know).
They are designed so they can not be mounted the wrong way. If they fit, you're doing great. We recommend that you fit the pieces together while pressing them horizontally in a table. Repeated task
Before we start we need to prepare fabric rectangles measuring 58x58cm. In order to glue the fabric to the frames we will use a hot glue gun. First start with one corner and tighten the fabric as you move onto the other 3 corners.
Continue along the sides and seal.
Pestañitas are the small pieces which hold the box and the frames together. When attaching them with the box pieces you will feel and hear a click.
Glue one box at a time. This is important because the glue dries relatively fast. Remember you are gluing in two dimensions, all contact surfaces must have glue.
Stick the box pieces together.
Glue the top edge for comfort. Remember all contact surfaces must have glue.
Align the pieces and press with care.
Start cutting Rockwool (or fiberglass) or Geopannel rectangles measuring 58x58cm and 4cm in thickness.
Then insert gently the Rockwool (or fiberglass) into the box and remove the excess material.
Repeat step 5, make sure the rockwool is not too tight.
Now you should have your very first Laser Absorbent Panel in your hands. I hope it looks great, but don't worry if it's not perfect. You will do it better with the next ones now that you know the process.
This tutorial is still quite new. If you think something is not explained enough or you got stuck somewhere, we really wanna know. Please send us an email to [email protected].
Any suggestions, any questions, anything... yes, we are at [email protected].
Has it helped you? Did you build it? Would you improve something? Please don't be shy, we take feedback really really well :)
Oh, and if you liked this tutorial, follow us for more!
It is very important for us to know if you had any difficulties and whether you made your own panel or not. In order to evaluate our tutorials we need to know how many individual persons have tried to make their own panels, and how many have succeeded.
