Anycubic Kobra S1 vs UltiMaker S8 — documented properties and sources

Identity
BrandAnycubicUltiMaker
ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1[1]UltiMaker S8 3D Printer[2][3]
Release date (announcement and actual shipping)Listed on the Anycubic store from 2 January 2025 (Shopify publish date)[4]Launched March 2025; the technical-specification and pricing announcement is dated 14 March 2025[3]
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)[4]Starting at $8,999 at MatterHackers, in stock, checked Aug 2026. The launch announcement quoted approximately $9,000[2][3]
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][5]Sold as printer-only or as a Pro Bundle. The bundle is not a trim level but a different machine footprint and weight: 495 x 500 x 1210.5 mm and 47.7 kg with the 6-spool Material Station, versus 495 x 585 x 800.5 mm and 30 kg for the printer alone. Print cores AA+ 0.40 x2 are included; BB, CC+ and DD 0.40 are separate purchases[2][3]

Machine footprint (mm) & clearance needed (cable/spool overhang)400 x 410 x 490 mm[1]495 x 585 x 800.5 mm printer only; 495 x 500 x 1210.5 mm as the Pro Bundle[2][3]
Net weight (kg)9.37 kg net, 20.2 kg packaged[1]30 kg printer only; 47.7 kg as the Pro Bundle[2][3]
Frame construction & materialNot documentedFully assembled, made in Europe[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][5]Enclosed, with an Air Manager UltiMaker says removes up to 95% of ultrafine particles[2][3]
Passive chamber temperature reached (if enclosed; measured values preferred)Not documentedBuild-volume temperature under 50 °C with open-loop control (manufacturer figure)[2][3]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (stated outright in Anycubic's specification table)[1]Dual-extrusion print head with auto nozzle-lifting, flood detection and inductive probing. UltiMaker's Cheetah motion planner uses third-order continuous motion with corner blending[2][3]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]Up to 500 mm/s in XY (manufacturer claim)[2][3]
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]Up to 50,000 mm/s2 (manufacturer claim)[2][3]
Jerk / square-corner-velocity setting (exact value)Not documentedJerk up to 100,000,000 mm/s3 (manufacturer claim)[2][3]
Max volumetric flow claimed (mm³/s)Not documentedUp to 35 mm3/s extrusion flow (manufacturer claim)[2][3]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Dual gripper feeder with tension adjustment, release function and filament feed-rate control[2][3]
Filament diameterNot documented2.85 mm[2][3]
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]Swappable print cores; AA+ 0.40 x2 included, BB 0.40 / CC+ 0.40 / DD 0.40 sold separately[2][3]
Max nozzle temp claimed AND firmware max temp limit (both values)320 C maximum nozzle temperature[1]Up to 340 °C (manufacturer claim)[2][3]
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]Up to 120 °C on a flexible PEI plate (manufacturer claim)[2][3]
Bed surface (material, texture, coating), single/double-sidedNot documentedFlexible PEI plate[2][3]
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]Inductive probing, integrated into the print head[2][3]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, filament entanglement detection and power-loss resume[1]Not documented
Spool holder location & max spool size; drybox compatibilityNot documentedDual spool holder with NFC recognition on the printer; the Pro Bundle substitutes a 6-spool Material Station with NFC and a dual-geared abrasion-resistant feeder[2][3]
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
Chamber/exhaust fan & filtration (activated carbon / HEPA)Not documentedAir Manager, which UltiMaker says removes up to 95% of ultrafine particles[2][3]
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS, with pressure advance and flow calibration supported[1]Not published; print preparation is UltiMaker Cura 5.10 or newer, fleet management via UltiMaker Digital Factory[2][3]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch capacitive touchscreen[1]Not documented
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]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-drivePrinter UI, slicing software, Anycubic app, USB (print only)[1]Wi-Fi 2.4 and 5 GHz (802.11a/b/g/n/ac), Gigabit Ethernet, USB 2.0[2][3]
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][5][6]Full HD HDR camera[2][3]
Materials Support
Officially supported filament listPLA, PETG, TPU, ABS, ASA[1]UltiMaker cites 301+ compatible materials including its own PLA, PETG, ABS, CPE, CPE+, PC, TPU and PET-CF, plus third-party grades[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]Under 50 dBA operating sound, manufacturer figure. No independent measurement; distance and method not stated[2][3]
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[7]12 months, extendable to 5 years with an UltiMakerCare plan[2][3]
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedDimensional accuracy +/-0.15 mm +/-0.15% of feature nominal length (manufacturer specification, not an independent measurement)[2][3]

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.
