Anycubic Kobra S1 vs Bambu Lab P1S: the enclosed multi-colour Combo or the original
The Anycubic Kobra S1 is an enclosed 250 x 250 x 250 mm CoreXY that launched around $420 alone and $550 as a Combo with the ACE Pro, a four-spool box that also dries filament. The Bambu Lab P1S is the printer it is modelled on: a 256 x 256 x 250 mm enclosed CoreXY at $699 alone and $949 with the AMS at launch, with the more mature software and a far larger community. The S1 Combo is the value pick for enclosed multi-colour; the P1S is the safer, better-supported one.The short version
Who should buy which
Both printers are in SpeakCAD's slicer catalog with their official OrcaSlicer profiles, so this page has no printer to sell you. The numbers in the table come from those profiles; the prices are the makers' launch prices, and prices moved in 2025 and differ by region.2
Buy the P1S if…
You want the printer with two years of refinement, Bambu Studio and Handy, a huge user base and the AMS chaining to 16 spools, and you will pay for it.3
Either way, the first custom part
Describe it with its measurements, check it on a virtual bed the size of the printer you chose, and download G-code for the Kobra S1 or a sliced .gcode.3mf for the P1S, sliced with its official profile. The first render usually appears within a minute or two: a new part gets deeper reasoning through the geometry, and small edits land in seconds.Anycubic Kobra S1 vs Bambu Lab P1S: the numbers

Parts that fit both beds
Copy one, change the numbers to yours. Each opens in the editor with the text already typed.“A hinged box 120 x 80 x 40 mm with a print-in-place hinge (0.4 mm clearance), a snap latch on the front, 1.6 mm walls.”
Open this prompt in the editor“A Raspberry Pi 5 case with a 30 mm fan grille, GPIO ribbon slot and two keyhole wall mounts, 2 mm walls, screwed lid on M2.5 pillars.”
Open this prompt in the editor“A headphone hook that screws to the side of a desk with two 4.5 mm holes 40 mm apart, a 30 mm deep arm with a 20 mm rounded end, 3 mm thick.”
Open this prompt in the editorWhere the Kobra S1 wins
- Price: about $420 alone and $550 as the Combo at launch, against $699 and $949.
- The ACE Pro dries filament as it feeds it; the AMS holds desiccant but does not heat.
- Hotend to 320 °C against 300 °C.
- Touchscreen against the P1S's small non-touch screen.
Where the P1S wins
- Bed width: 256 mm against 250 mm.
- Ecosystem: Bambu Studio, Handy, MakerWorld profiles, and years of firmware and documented fixes.
- AMS chaining: up to four units for 16 colours.
- Auxiliary part-cooling fan for PLA at speed in the enclosure.
What both give up
Neither has a heated chamber; both want the door open for PLA in a warm room; neither takes a G-code file straight from a phone browser (both go through their app or slicer, or a card or stick).
Prices
Launch prices above; both changed in 2025 and vary by region.
Verdict
If the budget is the constraint, the Kobra S1 Combo delivers most of the P1S Combo for much less, with a drying box as a bonus. If reliability of the whole experience is the constraint, the P1S remains the safer buy.
Sliced for either one
SpeakCAD ships the OrcaSlicer profiles of the Anycubic Kobra S1 and the Bambu Lab P1S, like 380+ other printers. Describe a part in plain English on a phone or a computer, watch it render on a virtual bed of the size above, change it by chat, and download G-code for the Kobra S1 or a sliced .gcode.3mf for the P1S, with the print time and filament weight. The STL and 3MF are always there for your own slicer. The Anycubic Kobra S1 and Bambu Lab P1S pages have prompts sized for each bed and the library parts made for them.
Questions
It follows the same recipe: enclosed CoreXY, a 250 mm class bed, a four-spool colour box, an app. It is Anycubic's own design with its own firmware and slicer, and it launched about a year and a half after the P1S.
The ACE Pro dries filament actively; the AMS is sealed with desiccant and chains to 16 spools with a longer record of reliability. Both purge at each colour change.
The P1S by a little: 256 x 256 x 250 mm against 250 x 250 x 250 mm in the profiles.
Yes, both, with the OrcaSlicer profile each maker ships: G-code for the Kobra S1 and a sliced .gcode.3mf for the P1S, or an STL or 3MF for your own slicer. The bed sizes in the table are the ones the viewer shows while you design.
