Is there a way to convert a P1S to dual nozzles? This would be to allow the use of two incompatible filaments (PLA and TPU).
That would be nice I wish I could do that with my x1c.
It is not currently possible to add a second nozzle to X/P/A series, and Bambu will never offer that as an add-on to any existing printer. The necessary changes make an entirely new printer design more economical to develop, produce, and purchase.
Let’s be honest—Bambu designs for obsolescence, plain and simple. This is a platform built for modification, yet Bambu treats upgradability like a threat. The hypocrisy—and the exploitation of their customer base—is hard to ignore. Contrast that with Prusa, which supports upgrades across three generations of printers. You don’t have to love Prusa, but at least they build machines with a future. Bambu? They toss you aside the moment the credit card charge clears. Think they’ll ever adopt a user-first ethos? The evidence and forum-wide complaints says otherwise.
An idex system would be nice, but the cost of the extra toolhead, extruder and drive system, and replacing the firmware and controller boards, would make it not worth the effort, plus you’d get a smaller build area.
A chimera type system would require an extra extruder and controller boards, too. Converting bbl stuff, is not worth the hassle, or expense.
I’m thinking, for me, I’d wait for the bondtech indx system, and install on some other klipper running printer.
Thanks for the replies. I was just asking. Didn’t mean to stir up a hornet nest.
A carriage that replaces the original print head could carry 2 or more heads, each with it’s own Bowden tube so the filaments would remain loaded. Rotary or linear movement to index to the desired one. A single digit (8 bits) could carry the command. The existing processor code sections would ignore that digit and pass it on to the added code or hardware/firmware. No time would be wasted moving to a hot end storage rack and then back to the printing area: the change could be made while traveling from the end of one filament’s printing path to the beginning of the next. Some of the elements of the present hot ends would probably need to be modified (miniaturized).
It could be done. The problems would start with the cost, which the customer would need to pay and the desire not to cut into the sales of new machines.

Something people tend to miss in these “what if” type conversations and goes to why it is cheaper to build a new design is the X/Y axis sq mm lost.
Bulid plate volume on P1S is 256mm (X) x 256mm (Y) X 256mm (Z)
Think of that as the very tip of the extruder, side to side, front to back, top to bottom is able to touch anywhere in that space.
Put another P1S nozzle in that space, right next to the existing toolhead and measure the distance from nozzle tip to nozzle tip. Just say that is 25mm which is not unreasonable considering the size of the entire toolhead assembly.
You’ve lost 25mm on left side and 25 mm on the right side.
To not lose that surface volume with a dual nozzle setup on a P1S chassis, each nozzle has to be able to hang out beyond the build plate by that 25mm on left and right.
I do not know about other folks but some of the things I make need almost all all of the 256mm in either X or Y.
When you start talking about multi-nozzles setups you immediately run into the issue of the voluume each nozzle occupies in the overall build volume.
Trying to solve that problem has led to the concept of tool-changer style printers. When printing there is only the lone nozzle where it always was but then you get into questions like where do you park the idle nozzles and the equipment to place and retreive nozzles.
You end up with a larger, heavier machine for no real gain in overall build volume.
Me personally, I’d like to see an machine similar to a no frills P1S type machine with a larger build volume I can connect my existing AMS’s to. That is rigid enough to maintain calibration over many prints.
Since I rarely do muli-color prints anyway, I would be way more interested in a 400mm X 400mm X 400mm updated but basically P1S with maybe a heated chamber.
I don’t think the P1S can be easily converted to dual nozzles. You’d likely need significant hardware and firmware modifications. A dedicated dual-extruder setup would be a better option for using PLA and TPU together.
