After creating an exhaust extraction system for my X1 last week, I had a request for one suitable for the Bambu Lab P1S. And, to create it with the ability to capture the exhaust pushed out the back fan. I learned that while the exhaust fan of the X1’s sucks air in, the exhaust fan of the P1S blows air out.
The idea is to capture the VOCs from the fan port and from the top of the machine at the same time, and then vent all of that away from the machine when desired.
This new P1S system is similar to my X1 system but has an extension that reaches down to the fan on the back side of the P1S. This necessitated moving the port in the top-mounted frame to the back right corner.
And, unlike the X1 system, the exhaust port of this system is built into the back vented corner of the frame and is open on the bottom (as well as the top) so that air can flow through the port (as well as out of the machine). The exhaust hose is then attached vertically off the back of the Exhaust Port. And, a new manifold (the “Funnel”) connects on the underside of the Exhaust Port to join an Exhaust Vent Cover which attaches magnetically over the P1S’s exhaust fan.
Similar to the X1 system this system is built around the idea of a frame that sits on the top of the P1S (under the glass) and the glass sits back on top of the new frame. The frame raises the glass 20mm. This exhaust is compatible with an AMS.
All the components of this system can be printed on a 250mm bed and all print without print support.
I designed this system to be compatible with my entire exhaust ecosystem which means you need to attach the “TubeEnd” on the top of the Flow-Through Exhaust Port. This requires a bead of glue on the contacting faces. But it is important to note that you can alternatively connect the Variable Flow Valve on the top instead which will allow you to shut the extraction off when it is not needed.
The Quick Release Head is part of an entire system of exhaust parts that you may want to be aware of. Please check it out here…

Also, the Variable Flow Valve is described here…

Please note I have now added LED lighting support bars allowing you to install an adhesive-backed LED lighting strip into the top of your machine for additional internal lighting. It is entirely optional.
I have included some small slots for zip ties in case the adhesive on the back of the lighting fails.
The LED strip bars simply drop into the frame and can be added anytime. Adhere an adhesive-backed LED strip to the underside of the LED strip bars and gently bend the strip around the corners. I have included an exit space for the LED electrical cord which can be plugged if not used.
I think you can use most types of LED strips but the 6mm wide style like the one I used is ideal. Here is a link to the one I used (in Canada) and a comparable one in the US.

Printing
I have tried to make my main print settings visible on the slicer screenshot but in case they are difficult to read I have summarized them again here…
Material: I chose to use PETG for the hose side and I used PLA for the exhaust frame and other parts.
My Setup:
Nozzle = 0.4mm
My Settings:
Layer height = 0.2mm
Line width = 0.4mm
Wall count = 4 (1.6mm)
Infill = 40%
Ironing = ON (not critical)
Support:
Designed to print without additional support.
Print Orientation: As shown in the screenshot(s).
Assembly Notes
Once printed, the frame simply rests on the top of the P1S (and under the glass). It can be removed at any time.
The assembly of the Flow-Through Exhaust Port requires gluing at an end for the hose to be connected to. Please see the accompanying illustration.
Please refer to this post for more details on assembling and using the exhaust system components.
