Photos of a printed quick start guide for the Bambu Lab AMS 3P and of the unit itself, compiled in a Reddit post on Oct. 28, show a seven-spool filament unit that sits on top of the printer and feeds seven tools. Bambu hasn’t announced it, and there is no price or release date.
The unit itself is real on paper. Bambu’s FCC filing for the AMS 3P (model SA018) was granted Sept. 21, 2026, and the lab tested it on model PF006-P, which FCC records list as the unannounced P3C.

What the Leaked Bambu Lab AMS 3P Quick Start Guide Shows
The images were gathered into an r/BambuLab post after appearing in comments elsewhere on the subreddit. Their origin isn’t documented, and Bambu hasn’t commented, so treat them as a leak until launch.
The pages show:
- Seven slots, numbered 1 to 7 across two rows, under a hinged lid with left and right struts
- Top mounting: the cover drawing puts the unit on the printer’s roof
- Seven feed tubes running down the side to seven tool positions, in a section titled “Install the AMS 3P”
- Bypass Feed on most slots, with a note that reads “No bypass feed available in slots 2 and 6”
- A Bambu Bus Port 6-pin and an External Spool Filament Inlet
Two photos show a physical unit with the lid open: a dark tub, clear spool rings and seven orange feed fittings. The guide pages never say what the bypass feed is for.
Bambu Lab AMS 3P Specs: Tested on the P3C, 24V Input
The AMS 3P’s label reads “Automatic Material System 3P” with an input of 24V at 1A, and the test report says it “is powered by the DC 24V supply” from the printer, model PF006-P.
Its RFID side uses five numbered coil antennas at 13.56 MHz. That count doesn’t line up with seven slots, and it doesn’t have to: the AMS 2 Pro holds four spools, and its test report lists two antennas.
The filing’s photos and user manual stay confidential until March 20, 2027, so the leak is the only look inside for now.

Bambu Lab AMS 3P vs AMS 3H: The Power Gap
The AMS 3H filing (SA017) was granted the same day. Its label lists 100-120V AC at 200W, or 24V at 1A, and its report says the RFID function runs on the printer’s 24V. It has seven coil antennas and was tested on PF008-P, the model number registered as the H3C.
Bambu’s current drying units have more power to work with. The AMS HT lists 100-240V AC at 150W next to the same 24V, 1A port. The AMS 2 Pro takes 24V at 4A, from an external adapter or from the H2D.
My read: at 24V and 1A, the AMS 3P has no power budget for drying. The AMS HT and AMS 3H labels list that same 1A port plus a separate mains input, most likely for heating. The 3P’s label lists only the port. The counter-evidence: its test setup does show an AC cable to the unit, and the confidential manual could still describe a feature the filings don’t show.
What the Bambu Lab AMS 3P Means for P1S, P2S and AMS 2 Pro Owners
If you own a P1S or P2S with an AMS 2 Pro or AMS lite, nothing on record says the AMS 3P fits your printer. The lab tested it only with the P3C, and the guide shows seven lines going straight into tool docks. Don’t hold off on an AMS purchase waiting for it.
If you were about to buy a P2S Combo for multicolor work, the AMS 3P makes the seven-tool Bambu Lab P3C look closer to a full package. Bambu hasn’t dated the P3C, though. If you buy now, check the Bambu Lab Black Friday 2026 prices first.
If filament drying matters to you, the AMS 2 Pro and AMS HT remain the Bambu units with their own mains supply. The AMS 3H’s 200W input points the same way, though Bambu hasn’t said it dries.
If you’re watching the H3C, the AMS 3H is the likelier match, since its lab test ran on the H3C. Bambu will reveal the H3C tool changer on Nov. 3 at 9:00 AM EST. Our H3C patent breakdown covers what the tool changer is likely to be.
Bambu Lab AMS 3P Price and Release Date: Not Announced
Bambu hasn’t listed a price, a release date or a store page for the AMS 3P. Its teaser page covers only the H3C.
Bambu Lab AMS 3P FAQ
What is the Bambu Lab AMS 3P?
It is an unannounced Bambu filament unit, model SA018, that was lab-tested on the seven-tool P3C. A leaked quick start guide shows seven spool slots under a hinged lid on the printer’s roof.
What is the difference between the AMS 3P and the AMS 3H?
The AMS 3P’s label lists 24V at 1A from the printer. The AMS 3H adds a 100-120V, 200W mains input and was tested with the H3C.
When will the AMS 3P be released and how much will it cost?
Bambu hasn’t announced either. The only dated Bambu event is the H3C reveal on Nov. 3, and the P3C doesn’t appear on that page.
What We Still Don’t Know About the Bambu Lab AMS 3P
- The price, and whether it sells alone or only with the P3C
- Whether any printer other than the P3C can use it
- What the bypass feed does, and why slots 2 and 6 lack it
- Whether it does any drying at all
- Whether the AMS 2 Pro or AMS HT can feed a P3C
The user manual that could settle some of these sits in a confidential regulatory file until March 2027.
