ClassCOREXYCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1[1]Bambu Lab P2S; spec sheet header "P2S Spec Sheet"[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$349.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $549.00 ($401.00 for the EU plug variant)[3]From $549.00 on the Bambu Lab US store, Aug 2026; the product page shows $749.00 with the P2S Combo variant selected[4][5]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The CoreXY line, not to be confused with the gantry/bed-slinger Kobra 3, Kobra 4 and Kobra X. Within the S line the Kobra S1 Max is a much bigger machine: 350 mm cube against 250, a 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 does not have at all, and 25.7 kg against 9.37 kg. Multicolour is sold separately on both (ACE Pro / ACE 2 Pro)[1][6]Two SKUs: P2S and P2S Combo (with the 2nd-generation AMS, which adds filament drying). Do not carry P1S figures across - the P2S differs on nearly every headline number: 600 vs 500 mm/s, 110 vs 100 C bed, hardened-steel vs stainless nozzle, 5-inch 854x480 touchscreen vs 2.7-inch monochrome, 14.9 vs 12.95 kg, 1920x1080 30 fps camera vs 1280x720 at 0.5 fps[2][7]
Market position: superseded? successor announced?Not documentedCurrent model, marketed by Bambu as "The Classic Evolves" - the direct replacement for the P1S, which is still sold below it[4]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 250 x 250 mm[1]256 x 256 x 256 mm (manufacturer figure)[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)400 x 410 x 490 mm[1]392 x 406 x 478 mm[2]
Net weight (kg)9.37 kg net, 20.2 kg packaged[1]14.9 kg net[2]
Frame construction & materialNot documentedPlastic and steel chassis with a plastic and glass outer frame[2]
Enclosure: open / enclosed; panel material; door/lidFully enclosed - Anycubic's own wording is "Fully Enclosed CoreXY Construction". There is no active chamber heating on the S1 (that is the S1 Max's addition)[1][6]Fully enclosed with a door sensor and an activated-carbon (granulated coconut shell) filter with VOC and particulate filtration. No active chamber heater is listed[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (stated outright in Anycubic's specification table)[1]CoreXY - Bambu positions the P2S as the successor to the P1S platform. The spec sheet itself does not name the kinematics[2][5]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]600 mm/s max toolhead speed (manufacturer claim); no independent measurement found[2]
Recommended/typical print speed300 mm/s recommended print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1]20000 mm/s2 max toolhead acceleration (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented40 mm3/s standard-flow hotend, measured by Bambu on a 250 mm round single-wall model in Bambu ABS at 280 C[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Direct drive with hardened-steel extruder gears, driven by a Bambu Lab high-precision permanent-magnet synchronous motor rather than a plain stepper; built-in filament cutter[2]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Quick-release hotend; 0.4 mm standard nozzle expandable to 0.25, 0.6 and 0.8 mm[1]Hardened-steel nozzle, 0.4 mm included, 0.2/0.4/0.6/0.8 mm supported[2]
Max nozzle temp claimed AND firmware max temp limit (both values)320 C maximum nozzle temperature[1]300 C claimed max nozzle temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C maximum hotbed temperature on a PEI spring steel build plate - the highest bed ceiling of any Anycubic machine in this file except the S1 Max[1]110 C max heatbed temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedFlexible steel plate; Textured PEI plate included, Smooth PEI Plate and Cool Plate SuperTack supported[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)LeviQ 3.0 auto-levelling with Z-offset, plus area levelling[1]Not documented
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, filament entanglement detection and power-loss resume[1]Yes - run-out sensor, tangle sensor, door sensor; filament odometry with AMS[2]
Multi-material/multi-color capability or official upgrade pathMulticolour is sold separately - the ACE Pro / ACE 2 Pro units are not included with the bare S1[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedPart-cooling fan, hotend cooling fan and auxiliary part-cooling fan, all closed-loop controlled[2]
Electronics & Power
Mainboard model & MCU (exact chip markings if teardowns exist)Not documentedMotion controller is a dual-core Cortex-M4 plus a single-core Cortex-M7; application processor is a quad-core 1.5 GHz ARM A7 with a 2 TOPS neural processing unit. Board model and chip markings not published[2]
Total rated power drawNot documented100-120 VAC / 200-240 VAC 50/60 Hz; max 1200 W at 220 V, 1000 W at 110 V; steady state 200 W printing PLA[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS, with pressure advance and flow calibration supported[1]Closed-source proprietary firmware - not a Klipper or Marlin derivative, and no printer-firmware source is published. The bambulab GitHub organisation carries 11 repositories (Bambu Studio, wxWidgets/boost/ffmpeg forks, the wiki); none is printer firmware. Updates are delivered over the air via Bambu Studio / Bambu Handy[8]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen[1]5-inch 854x480 touchscreen[2]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus slicing software, the Anycubic app and USB (print only); AI spaghetti detection and object-skip supported[1]Touchscreen plus mobile app and PC app; Bambu markets on-device AI error detection[2]
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app, USB (print only)[1]Dual-band Wi-Fi (802.11 a/b/g/n, 2.4 and 5 GHz), built-in 8 GB eMMC and a USB port. Ethernet not available; no network kill switch and no 802.1X[2]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, but only 480p - lower than the 720p units on the S1 Max, Kobra 4 and Kobra X[1][6][9]Built-in camera, 1920x1080 at 30 fps - a real video-rate camera, unlike the 0.5 fps unit in the P1 series[2][7]
Materials Support
Officially supported filament listPLA, PETG, TPU, ABS, ASA[1]PLA, PETG, ABS, ASA, TPU, support materials, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)46 dB or less in standard mode and 44 dB or less in quiet mode - manufacturer figures with no distance or method stated, so not comparable with an independently measured reading[1]Not documented
Reliability, Support & Ecosystem
Warranty length & support reputation (evidence, not vibes)One year on the complete machine (excluding gifted and second-hand machines), with component warranty periods that vary by part; the period starts on the delivery date and is suspended while a replacement is in transit. Anycubic states it will follow longer local statutory periods where they apply[10]2-year limited warranty for consumers in the US, Canada, the EU, Switzerland, Norway and Iceland; 1 year in the rest of the world. Bambu Lab's own policy records the US/Canada term as a 2026 extension from one year to two[11]

Manufacturer claims, independent measurements, packages and test conditions retain their source wording. FDM linear speed and resin vertical speed use different units and are not directly comparable. Unknown values are marked “Not documented”. Prices and source dates remain historical snapshots; check the linked guide for product details. Differences highlight text, not a universal winner.
