Anycubic Kobra S1 vs UltiMaker S7 — documented properties and sources
PropertyAnycubic Kobra S1COREXYUltiMaker S7INDUSTRIAL
Identity
BrandAnycubicUltiMaker
ClassCOREXYINDUSTRIAL
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1[1]UltiMaker S7[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]$5,999.00 for the standard model at 3D Universe, in stock, checked Aug 2026[2]
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][4]Same 330 x 240 x 300 mm envelope as the S5 and S8. The S7 is distinguished from the S5 by a PEI-coated flexible build plate (rather than glass) and dual-band Wi-Fi; from the S8 by nozzle temperature (S8 reaches 340 °C) and speed (S8 quotes 500 mm/s and 50,000 mm/s2)[2][5][6]
Market position: superseded? successor announced?Not documentedSuperseded by the S8, launched March 2025, which UltiMaker markets as four times more productive[6][7]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable250 x 250 x 250 mm[1]330 x 240 x 300 mm[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)400 x 410 x 490 mm[1]495 x 585 x 780 mm with the spool holder[2]
Net weight (kg)9.37 kg net, 20.2 kg packaged[1]Not documented
Frame construction & materialNot documentedFully assembled professional chassis[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][4]Not documented
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (stated outright in Anycubic's specification table)[1]Dual-extrusion gantry with auto nozzle-lifting and swappable print cores; kinematic layout not published[2]
Speed & Acceleration
Max print speed (claimed, mm/s)600 mm/s maximum print speed (manufacturer claim), 300 mm/s recommended[1]Not documented
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]Not documented
Max volumetric flow claimed (mm³/s)Not documentedBuild speed under 24 mm3/s (manufacturer figure)[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion")[1]Dual extrusion with swappable print cores[2]
Filament diameterNot documented2.85 mm[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]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)320 C maximum nozzle temperature[1]Not documented
Stock nozzle size & sizes included in boxNot documented0.4 mm standard; 0.25, 0.6 and 0.8 mm available separately[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]PEI-coated flexible build plate, 20-140 °C[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedPEI-coated flexible build plate[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]Not documented
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
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Kobra OS, with pressure advance and flow calibration supported[1]Not documented
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 GHz and 5 GHz, LAN, USB[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][4][8]Not documented
Materials Support
Officially supported filament listPLA, PETG, TPU, ABS, ASA[1]Not documented
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[2]
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[9]Not documented
Independently Measured Performance
Dimensional accuracy measurements (third-party, with numbers)Not documentedXYZ resolution 6.9 / 6.9 / 2.5 micron (manufacturer specification)[2]

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.
