An Honest Comparison between the Bambu Lab P1S and the A1! Features - AMS Units and Noise Levels! 

I have a p1p that I upgraded to a p1s. I just bought myself an AI too lol. This video was perfect for me to binge while waiting for it.

Great video with lots of useful information. Similarly to you, in the summer I run into humidity issues but having my setup in the basement even with the AC on I sit around 64% humidity. I found that with the AMS system with enough silica gel packets I can keep it relatively low. One day will add the A1 to my collection but for now I'm eyeing the P1S.

A useful detailed comparison, thanks.

Have been 3d printing since 2018. Have 7 printers. Got an A1, those 7 printers now doomed for replacement, the ecosystem , quality of prints and pure ease of use Bambu offers will decimate the market of all other manufacturers in this sector as they so far behind Bambu.

Thank you for this video.

I wish they do a refresh on all the X and P series, the P1 series screen feels super old compared to the newer A series

I've had my X1 for about a year now. Recently, slightly before the sale, I bought an A1 based on a review. I enjoy each of them. It is so much easier to swap the nozzle / heater on the A1. The very first time used my new X1 I selected the Bambu PLA CF filament. At the end of the print I experienced a filament break, about 1/8 inches about the heater assembly. For me it turns out that contacting customer support for Bambu is awful. I have yet to complete a customer service request due to the complexity of the request procedure. On the other hand, I was able to find a video that explained how to remove the filament fragment and I was also able to swap out the assembly. A few months ago I upgraded to the hardened hot end for the X1. Changing that proved to be a bit of a problem because it's just awkward getting the nozzle assembly attached with the heater and the thermal paste. It was a mess. I started doing some Lithaphanes with my A1 and learned that the best way to do this was with a .2 nozzle. Swapping the A1 nozzle was a snap, well two snaps, but it was so much easier than the X1. Coming from roots with an Ender 3 Pro, I had already cut my teeth in printer upgrading and maintenance, so my experience with Bambu was a relative breeze. Now, with the X1 and the A1 I spend my time printing.

For me, the A1 got the nod due to the ease of switching out nozzles. With AMS lite and being able to switch from 0.2 to 0.4 in about a minute, it has made just simple printing fun without all the hassles of changing filaments, bringing out the toolbox when there is a clogged nozzle, or sweating breaking something. The printer heads are cheap enough i keep a few on hand to switch out if there is an issue instead of spending valuable time trying clean a clog.

Purchased a P1S a couple months ago, love it. The deciding factor for me was the P1S being enclosed and I nylon

Great video as always and great comparisons! I really love my P1S and I'm so glad I listened to you and got into the Bambu Eco system. I usually don't mind tinkering with stuff but its SO much nicer to actually spend more time printing and less time fixing the printer! I've had some minor issues but everything will eventually have problems. I'm sitting around 600 print hours on the P1S and almost every issue until recently, has been from a setting I overlooked. I did have a Wi-Fi issue once but never had it again. I'm glad I got the P1S but I do really want the A1 a lot more after getting the A1 mini in the other day. They both have their pros and cons but my mini is so quiet! The purge reflector threw me off for a second on my first print, I wasn't expecting it to just launch the poop across the room like a monkey at the zoo haha. Its definitely really hard to determine the best printer in the Bambu ecosystem though and I think thats a good thing! The X1C has its benefits with the Lidar, camera, screen, and higher temps for a larger variety of filaments but its just so expensive. The P1S has so much going for it being an enclosed Core XY printer and setting up a mini print farm with it is super easy when you can technically fit like 12 printers without AMS's on a 48"x72" adjustable shelving unit. Also being able to print higher temp materials like ABS, ASA is great. Bambu says its capable of printing PA and PC but I'm not exactly sure what upgrade is needed for that when most Nylon's want the bed to be 120C. The A1 gives you the same print volume and basically the same quality that prints 90% of what the average user will print for quite a bit cheaper than the P1S while being significantly quieter too. And the A1 mini is the perfect printer for anyone just getting into the hobby or wanting to pick up an amazing yet affordable printer for their kids or family members. Even though I had larger printers like the SV03, the vast majority of my prints were and still are under 180mm. The quick swap nozzles on the A1 is a game changer though and hopefully Bambu switches their Core XY printers over to that with new releases. I do think the P1P should be discontinued though, the A1 mini has the same print quality and size for minimum $200 less. And upgrading it to a P1S costs more than just getting the P1S. its funny that you mentioned how long it too to assemble your Prusa, my first printer was an Anet a8 that was a Prusa clone and it took me a good 4-6 hours to assemble it only to find out the control board was bad lol. The A1 mini was faster to assemble than my P1S since it was like 6 screws or something to mount stuff on but I don't think the P1S took me more than 15 but I didn't have the AMS. It was about an hour to start printing because of the firmware update, calibration, and having to setup an account. Anyway, a lot of great information here and I really wish I had this video before buying my first Bambu printer! It wouldn't have made much of a difference since I went to buy the A1 combo on the day of the recall lol but if I was starting over right now, this would have been so helpful! I can't wait to see the other videos you make with these printers.

Great information. I bought the A1 combo. Do you think a person could enclose just the AMS lite in an enclosure and make the humidity problem a lot less of a problem?

Rally nice comparison! Can you tell me where you got the printable mods for the P1S?

I got an A1 non-combo during the sale to get my foot in the door with 3d printing. Have only had it a week and have over 30 hours printing (to include more technical filaments like PA6-CF). Didn't want to blow my budget because I already have intentions of getting their new rumored "flagship" printer that is slated to release later this year.

Thanks for this. I already had an A1 Mini and bought a full size A1 because of the sale. No AMS on either unit though. I absolutely love the A1 series. I'm hoping for bambu's next gen P series they implement the A1 tech like the better nozzle cleaning, easier nozzle swaps, dynamic flow calibration, etc. Basically what I'd like is a core x/y A1. Catch you on the next one!

Do you have links for the mods for your P1S? Thanks for the videos!

Great video, FYI there is some pretty jarring clipping or resonance panning over to the left from your mic. With headphones it is quite noticeable. But great video, and timely!

My A1 is struggling keeping the nose clean.. Always some strings from hotend. Even when idling there is something hanging, and when calibrating I it's some string dragging along... I might need to hear with Bambu Lab.. It likes to let some filament out after finishing job and cleaning.. So it's there just hanging

Can you upgrade the camera on the p1s?

How is the print quality of the A1 to p1s?

The mini is the same as the A1 with a smaller bed. My P1S is approaching 3000 hours and I've replaced the print head once. The only real problem is that it lost my wifi network and I could never get it to work again. I finally got a mesh router and plugged it in to my ISP modem and could get the P1S to work with that. I used my phone's mobile hotspot in the intervening months. Not a common problem though from what I can tell so not a deciding factor. It is my go-to printer. Also have two A1's with AMS Lite and one mini. The A1's do a good job but they are limited by the moving bed which makes tall thin items harder. Bed has slightly more real-estate because there is no exclusion zone like the P1S. P1S is 10% faster. AMS Lite is better than regular AMS. A1's do have more problems breaking down, especially if you use a lot of silks and multi-color filaments like my wife does. I've replaced hot end heaters twice, which is a bit of a pain. I'm often having to clear nozzles on the A1s. We must have a dozen of the things lying around. I've had to replace one extruder. I replaced one of the beds when the new bed shipped, but that one's bed had died a week before the replacement came in. The other is still using the existing bed. We'll swap that out if we ever need to, but for now it works fine. ATM my older A1 is having a z-height problem that I'm working on and the other isn't heating the hot end again. I asked my wife to call in a ticket as I'm tired of paying for equipment failures and want to see if Bambu can fix something simple. My wife beats the A1's like a rented mule, so I think her use profile is probably close to a print farm, but my opinion is that if I were going to build a print farm, it would be with P1Ps since enclosures don't work well in print farms (nobody needs an opaque printer with a glass door hanging out.) The mini is too new for me to declare anything, but with maybe a hundred hours on it, it's been a champ.

Good comparison and I agree with you on some points. But, really different beasts. P1S will print PLA, including really crappy filaments (99% of the hobbyist use) all year flawlessly. Can't say the same about A1. I run a farm and I know the pains of open bed slingers, during cold months, even the best of PLA's start to warp and shift. For this reason I will choose P1S over A1 always. Not against bed slingers, just think corexy enclosed has distinct advantage. And one final thing, the heated bed cable issue they had, just wait till the bed has done 3000-4000 hours, that cable will go again. I has done for all Prusa's, all creality machines, and every other bed slinger on the plant.

Good video 👍 Im really sad i switched my a1 for the p1s during the heat bed call back. The ams lite was amazing, i had ams lite with the printer. The p1s i have no ams now and i miss it. The a1 was amazing, never had 1 print fail. The p1s has a 85% fail rate so far and is alot more difficult to problem solve and maintain. I would definitely go for the a1 over the p1s in future. My creality k1 runs circles around my p1s and was half the price. K1 print fail rate 5%

If I had the money ..... I would try to connect the AMS to a A1 mini or alternatively AMS LITE to an X/P. I would then disconnect the pins with a Pin Removal Tool Kit from a PC. so if someone is going to do it who has enough money let me know how okey ;)

Both are mid, vorons are better. P1S has false marketing as well. The promotion material indicates it has geared idler wheels but in the actual machine it's smooth.
