Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra 4[1]Bambu Lab P1S. Store title: "Bambu Lab P1S 3D Printer"[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 29 May 2026 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$279.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $379.00 ($320.90 for the EU plug variant)[3]From $369.00 (base P1S) on the Bambu Lab US store, Aug 2026, against a stated typical price of $399.00; with the P1S AMS 2 Pro Combo variant selected the same page shows $539.00 against a typical $579.00[4][2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)Shares its 260 mm cube volume and its exact machine dimensions (455.4 x 445.3 x 461.3 mm) with the Kobra X, so those two cannot be told apart on size. The difference is multicolour: the Kobra X ships with native 4-colour capability, while the Kobra 4 needs an ACE 2 Pro unit for multicolour and drying. The Kobra 4 also has a smaller 3.5-inch screen where the Kobra 3 and S1 use 4.3-inch panels[1][5][6]Enclosed version of the P1P and mechanically the same motion platform. Three SKUs on one product page: P1S, P1S AMS Combo and P1S AMS 2 Pro Combo (the AMS 2 Pro adds active filament drying). Sibling figures that get mixed up: net weight 12.95 kg (P1S) vs 9.65 kg (P1P); depth 389 mm vs 386 mm; ABS/ASA Ideal (P1S) vs Capable (P1P). Also distinct from the 2026 P2S, which is a different machine (600 mm/s, 110 C bed, 5-inch touchscreen, 14.9 kg)[2][7]
Market position: superseded? successor announced?Not documentedStill sold in Aug 2026, but Bambu now markets the P2S as "The Classic Evolves" above it in the same enclosed-CoreXY slot[4][8]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 260 x 260 mm[1]256 x 256 x 256 mm advertised. Bambu's own footnote sets the default printable height in Bambu Studio to 250 mm to prevent heatbed collisions, and notes the collapsible filament-cutter stopper occupies part of the print area when popped out[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)455.4 x 445.3 x 461.3 mm for the printer; the optional ACE 2 Pro is a separate 368 x 291.5 x 236.5 mm unit[1]389 x 389 x 458 mm; package 485 x 480 x 530 mm[2]
Net weight (kg)9.9 kg for the printer (ACE 2 Pro 3.7 kg); packaged 12.6 kg bare or 17.5 kg as the Combo[1]12.95 kg net, 17.60 kg gross; the AMS Combo ships at 21.60 kg gross and the AMS 2 Pro Combo at 21 kg gross[2]
Frame construction & materialNot documentedSteel chassis (shared with the P1P) inside plastic and glass panels[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Fully enclosed - plastic and glass panels with a glass front door and lid, plus an activated-carbon air filter. No active chamber heater; the chamber temperature regulator fan is closed-loop controlled[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Anycubic's table gives the construction as "Gantry system" - a bed-slinger, not CoreXY[1]CoreXY driven by two stepper motors, each with an independent belt to the printhead; the P1P and P1S share the same motion system[9]
Z-axis: leadscrew count & type, sync mechanism, anti-backlashNot documentedThree leadscrews belt-driven from a single stepper motor, whole bed moving in Z; manual tramming by three knobs under the bed, no motorised Z-tilt[9]
Belts (type, width, e.g. Gates?)Not documentedRear adjustable belt tensioners with a Belt Tension Monitor[9]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s the default[1]500 mm/s max toolhead speed (manufacturer claim); no independent measurement found[2]
Recommended/typical print speed300 mm/s default print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended[1]20 m/s2 = 20000 mm/s2 max toolhead acceleration (manufacturer claim)[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Direct drive; the service part is the "Stainless Steel Extruder Unit (P1 series)"[9]
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Hardened-steel nozzle, 0.4 mm standard with 0.25, 0.6 and 0.8 mm optional[1]All-metal all-in-one hotend with the nozzle integrated into the heatblock, replaced as a unit; 0.4 mm stainless-steel nozzle included, 0.2/0.6/0.8 mm optional[2][9]
Max nozzle temp claimed AND firmware max temp limit (both values)300 C maximum nozzle temperature[1]300 C claimed max hot-end temperature[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit100 C maximum hotbed temperature on a PEI spring steel build plate[1]100 C max build-plate temperature[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedTextured PEI plate; Cool Plate, Engineering Plate and High Temperature Plate compatible[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)LeviQ 3.0 49-point auto-levelling with Z-offset; Anycubic claims levelling repeatability under 0.02 mm and states no manual compensation is needed[1]Nozzle-touch probing using three ceramic force (piezo) sensors mounted under the heatbed - Z homing is done by detecting the force of the nozzle contacting the bed[10][9]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Yes - filament run-out sensor[2]
Multi-material/multi-color capability or official upgrade pathMulticolour and active drying both require the separate ACE 2 Pro unit; Anycubic quotes 4 independent brushless feed motors in that unit[1]AMS-compatible; sold as P1S AMS Combo and P1S AMS 2 Pro Combo, up to 16 colours with four AMS units[2]
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedPart-cooling fan plus auxiliary part-cooling fan, control-board fan and chamber temperature regulator fan, all closed-loop controlled (all four are merely Optional on the P1P)[2]
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedChamber temperature regulator fan with an activated-carbon air filter[2]
Electronics & Power
Total rated power drawNot documented100-240 VAC 50/60 Hz; 1000 W at 220 V, 350 W at 110 V[2]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS with pressure advance and flow calibration; a built-in accelerometer drives vibration compensation[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[11]
Connectivity, UI & Camera
Display: size, type, touch?3.5-inch capacitive touchscreen - smaller than the 4.3-inch panels on the Kobra 3 and S1 series[1][6][12]2.7-inch 192x64 monochrome screen, not a touchscreen; control by button, app or PC application (P1 series)[9]
On-device UI capabilities (model preview, per-object controls, etc.)Touchscreen plus Anycubic Slicer, the Anycubic app and USB; AI spaghetti detection and object skip supported[1]Button-driven monochrome on-device UI; job setup happens in Bambu Studio or Bambu Handy[9]
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveUSB, Anycubic Slicer and the Anycubic app[1]Wi-Fi, Bluetooth and Bambu-Bus, microSD card storage, 5 V/1.5 A USB output power (P1 series)[9]
Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps)Standard HD camera fitted, 720p[1]Low-rate chamber monitoring camera, 1280x720 at 0.5 fps, timelapse supported[2]
Calibration Routines & QoL
Assembly level & time from unbox to first printAnycubic claims assembly and first print within 15 minutes[1]Not documented
Materials Support
Officially supported filament listPLA, PETG, TPU 95A - and Anycubic notes TPU 95A cannot be used through the ACE 2 Pro[1]Ideal: PLA, PETG, TPU, PVA, PET, ABS, ASA. Capable: PA, PC[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)48 dB or less in standard mode and 45 dB or less in silent print mode - manufacturer figures with no distance or method stated[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[13]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[14]
Independently Measured Performance
Benchmark print times (source + settings)Anycubic claims a 14-minute Benchy - a manufacturer figure with no slicer settings published, not an independent measurement[1]Not documented

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.
