What the Combo box contains
This listing is the P2S Combo: the P2S printer plus one AMS 2 Pro filament unit. The listing's model field reads PF004-U+SA007-AU, and the cover of the quick start guide attached to the listing is titled P2S AMS Combo and carries the part codes PF004-U and SA007, so the listing and the maker document carry the same two part codes; the guide does not print the listing's -AU suffix, and neither source explains it.
The distinction matters because the listing itself notes that the P2S printer on its own does not support multi-colour printing and that the Combo is required for it. The user manual says the AMS 2 Pro adds RFID filament sync, automatic multi-colour and multi-material changing, and filament drying.
The listing gives the Combo as 18 by 22 by 18 inches and 46.3 pounds. Bambu Lab's specifications page lists the printer alone at 392 by 406 by 478 millimetres with a net weight of 14.9 kilograms, and the listing does not say whether its figures cover the printer alone or the whole Combo. Confirm with the seller and measure your bench for both units.
The core numbers from Bambu Lab's specification page
The build volume is 256 by 256 by 256 millimetres. The chassis is plastic and steel with a plastic and glass outer frame. The nozzle and extruder gear are both hardened steel, the included nozzle is 0.4 millimetres, and 0.2, 0.6 and 0.8 millimetre nozzles are listed as supported. A filament cutter is built in and filament diameter is 1.75 millimetres.
Maximum nozzle temperature is 300 degrees Celsius and the heatbed reaches 110 degrees. The included plate is a textured PEI plate on a flexible steel sheet. Bambu Lab gives a maximum toolhead speed of 600 mm/s, which matches the listing's headline, with acceleration of 20,000 mm/s squared and a maximum hotend flow of 40 cubic millimetres per second.
That flow figure comes with its own test conditions on the specification page: a 250 millimetre round model with a single outer wall, printed in Bambu Lab ABS at 280 degrees. The specification page gives no flow figure for any other model, filament or temperature, so read the 40 cubic millimetres as the result of that one stated test.
Enclosed, but the chamber is passive
The manual says the passive chamber temperature can reach up to 50 degrees Celsius, and the P2S FAQ states plainly that the printer has no active chamber heating. Instead, the FAQ says, it manages the chamber through the enclosure and an automatic flap.
The manual calls this the adaptive airflow system. In cooling mode, which the manual gives for PLA and TPU, an auxiliary part cooling fan draws in outside air and exhaust leaves through vents at the back. The printer selects the mode automatically by filament, and the manual says you can override it manually.
Filtration is activated carbon, with VOC and particulate filtration listed as supported on the specification page. The manual mentions an optional external exhaust fan kit and an optional auxiliary fan for the left side, and points to the Bambu Lab wiki for both; neither is in this box according to the listing's contents.
Which filaments, and what the AMS 2 Pro will not feed
The specification page lists a long filament range, including PLA, PETG, ABS, ASA, TPU, PC, PA, PVA and several carbon and glass fibre blends such as PLA-CF, PETG-CF, ABS-GF and PA6-CF. The manual's printing conditions table gives nozzle ranges, for example 190 to 230 degrees for PLA Basic and 260 to 290 degrees for PC.
The same table marks the fibre-filled filaments as hardened steel nozzle only, which the P2S ships with. It lists TPU 90A as AMS HT only, and the manual's safety notes say not to load TPU at 95A or softer, or moisture-exposed PVA and BVOH, into the AMS 2 Pro, and not to load TPU through the printer's filament buffer, other than the TPU made for the AMS.
The AMS 2 Pro accepts spool widths from 50 to 68 millimetres and diameters from 197 to 202 millimetres, and plastic spools are recommended. The FAQ says the P2S can connect up to four AMS 2 Pro and four AMS HT units, for 20 slots in total. Only one AMS 2 Pro comes in this box.
Drying, power and where to put it
The listing claims the AMS 2 Pro dries filament at up to 65 degrees; that figure is not on the Bambu Lab pages we read. What the FAQ does say is that drying from the printer's own power works for a single AMS 2 Pro on the 6-pin cable while the printer is in standby, and print functions pause during drying. Extra units need Bambu Lab's separate 24 V, 96 W power adapters.
The specification page lists 100 to 120 or 200 to 240 volts AC. Maximum power is 1,000 watts at 110 volts, held for about three to five minutes while the heatbed heats, and steady-state power while printing PLA is 200 watts. The listed working temperature range is 10 to 30 degrees Celsius.
The manual asks for a level, sturdy platform and a clean workspace. The maintenance table sets weekly build plate care, monthly camera and X-axis maintenance, and a three-monthly air filter clean with periodic replacement of the activated carbon filter, and it says to shorten every interval if the printer runs more than eight hours a day or prints engineering filaments for long periods.
Network, cloud and what we could not confirm
The P2S connects over dual-band Wi-Fi. The specification page lists Ethernet, a network kill switch and a removable network module as not available. Storage is 8 GB of internal memory plus a USB port. The same page lists 802.1X network authentication as not available.
The manual describes a LAN Only mode that blocks remote internet access and cloud features such as Bambu Handy and print history, and a developer mode that can be enabled only after LAN Only is on and lets third-party software control print jobs; the manual warns that this may involve security risks. Binding the printer to the Bambu Handy app during setup can be skipped. Third-party slicers that export standard G-code are supported, though Bambu Lab says some advanced features may not work.
Two claims we could not verify. The listing promises printing within 15 minutes of setup, and no maker page we read gives a setup time. And we did not read a Bambu Lab warranty document, so no coverage term is stated here; ask Bambu Lab or the seller for the warranty terms before you buy.
