Bambu Lab A1 vs Anycubic Kobra 3: AMS lite or ACE Pro?
The Bambu Lab A1 (256 x 256 x 256 mm) and the Anycubic Kobra 3 (255 x 255 x 260 mm in its profile) are open bed slingers of the same size and speed class, each with a four-spool colour box: the AMS lite on the A1, the ACE Pro on the Kobra 3. The ACE Pro dries the filament it holds, which the AMS lite does not; the A1 has the more mature software, the quick-swap hotends and the larger library. Launch prices were close: $559 for the A1 with AMS lite, about $450 for the Kobra 3 Combo. Buy the Kobra 3 Combo for dried multi-colour on a budget; buy the A1 for the ecosystem.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.Buy the Kobra 3 if…
You want a filament box that also dries the spools, a lower Combo price, and OrcaSlicer-based software. You accept a younger ecosystem.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 a sliced .gcode.3mf for the A1 or G-code for the Kobra 3, 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.Bambu Lab A1 vs Anycubic Kobra 3: 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.”

Both machines have direct drive, auto levelling, a PEI sheet and a 4.3-inch class screen, print at similar rated speeds, and connect over Wi-Fi to their maker's app. Both colour boxes are single-nozzle systems that purge at every change.
Where the Kobra 3 wins
- The ACE Pro dries filament while it feeds it, which matters for PETG and anything hygroscopic; the AMS lite is an open unit with no drying.
- Price: about $300 alone and about $450 as the Combo at launch, against $399 and $559.
- Slicer: Anycubic Slicer Next is an OrcaSlicer fork; OrcaSlicer works too.
Where the A1 wins
- Hotends: the complete hotend swaps in a minute, with 0.2 to 0.8 mm options.
- Calibration: automatic flow and vibration calibration, refined over two years.
- Ecosystem: Bambu Studio, Handy, MakerWorld, and a user base large enough that every problem has a thread.
- Camera in the box.
What both give up
Neither is enclosed, so ABS and ASA are not their material. Neither takes a G-code file straight from a phone browser: both go through their app, their slicer on a computer, or a card or stick.
Prices
Launch prices above; both changed in 2025 and vary by region.
Verdict
The Kobra 3 Combo is the better value for multi-colour, and the drying box is a real advantage with PETG. The A1 is the more refined printer with the deeper ecosystem. Either prints functional parts well.
Sliced for either one
SpeakCAD ships the OrcaSlicer profiles of the Bambu Lab A1 and the Anycubic Kobra 3, 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 a sliced .gcode.3mf for the A1 or G-code for the Kobra 3, with the print time and filament weight. The STL and 3MF are always there for your own slicer. The Bambu Lab A1 and Anycubic Kobra 3 pages have prompts sized for each bed and the library parts made for them.
Questions
Yes, it heats the box while feeding, which keeps PETG and other hygroscopic filaments printable through a humid week. The AMS lite is open and does not dry; Bambu's sealed AMS on the P1S and X1C holds desiccant but does not heat.
Effectively: a 256 mm cube for the A1 and 255 x 255 x 260 mm in the Kobra 3's OrcaSlicer profile.
The A1's, by track record: Bambu Studio and Handy have been refined for years and MakerWorld carries tuned profiles. Anycubic's Slicer Next is an OrcaSlicer fork and works well; the app is less mature.
Yes, both, with the OrcaSlicer profile each maker ships: a sliced .gcode.3mf for the A1 and G-code for the Kobra 3, or an STL or 3MF for your own slicer. The bed sizes in the table are the ones the viewer shows while you design.
