I am working on double-walling the P1S for thermal efficiency and noise reduction. I will be updating this post (i.e. the first post in this thread) with project updates as well as discuss further down the page.

I had previously reduced the printer noise by adding a sound deadening product designed for cars. This works well but the sticky edges of the sheets collect bits of filament and dust and doesn’t look great overall. You can read more about this on it on this thread.
This is mainly a more serious fight against noise. To start off with the noise reduction for the side panels work via the following mechanisms:
- “Mass load” the thin side panels to make them act less like drum skins,
- Introduce a rubbery material in the vibration path which removes vibration energy through hysteresis (think dampers),
- Double-wall the side panels,
- Make the outer skin ineffective at radiating noise - the surface is perforated with many small holes and perforated panels work very poorly as speakers,
- And finally - add some noise absorption to reduce the reverberance in the room - the perforated surface make poor sound reflectors and work like acoustic panels.
It also offers thermal insulation for:
- Improved energy efficiency - as less energy will be required to heat the bed,
- Reduced warping of parts - the chamber can maintain a higher temperature, especially in colder areas.
Here are some progress pictures:
Around the edge are pockets for M3 nuts and holes for M3 screws, to be able to attach the second door, top panel, etc. (No heat-set inserts, screw… them)
I will put all files on Makerworld once I get some good pictures and put a link here.
I also have a “control” unmodified P1S to do comparisons with later.

I’ve uploaded the files for the side panels on Makerworld, check out this collection.
