Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Kobra S1 Max[1]Snapmaker U1 3D Printer[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 16 January 2026 (Shopify publish date)[3]Not documented
Street price (USD; dated snapshot per entry)$699.00 with a US plug on store.anycubic.com, Aug 2026, against a compare-at price of $899.00 ($804.00 for the EU plug variant)[3]$849.00 against a $999.00 compare-at price on us.snapmaker.com, but the listing is marked Unavailable, checked Aug 2026[2]
Variants & sibling models — and how to tell them apart (spec-contamination risk)The large enclosed Anycubic. Against the Kobra S1: 350 mm cube against 250 (Anycubic claims 174% more volume), 350 C hardened-steel nozzle against 320 C, 65 C active chamber heating that the S1 lacks entirely, a titanium-alloy throat tube and hardened-steel extruder gears, an activated carbon filter, 720p camera against 480p, and 25.7 kg against 9.37 kg. Its engineering-filament list is correspondingly longer[1][4]An optional top cover changes what the machine can print: without it PLA/PETG/TPU/PVA/PCTG; with it ABS, ASA, PA, PC and PET are added; with the top cover AND a hardened-steel nozzle, carbon- and glass-fibre grades. A stated material list for the U1 is therefore meaningless without saying which configuration it refers to[2]

Enclosure: open / enclosed; panel material; door/lidFully enclosed CoreXY with 65 C active chamber heating, dual external-circulation cooling fans and an activated carbon filter, plus a temperature and moisture display[1]Open as sold; a top cover is an optional accessory that raises the supported material range[2]

Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)CoreXY (stated outright in Anycubic's specification table)[1]Four independent toolheads on a changer; Snapmaker quotes a 5-second swap[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[1]20,000 mm/s2 maximum (manufacturer claim)[2]
Max volumetric flow claimed (mm³/s)Not documented32 mm3/s maximum hotend flow (manufacturer claim)[2]
Vibration Compensation / Input Shaping
Input shaping supported? Implementation (Klipper IS / Marlin ZV / proprietary)Not documentedInput shaping with an accelerometer, run as a calibration routine[2]
Extrusion Pressure Control
Pressure advance (Klipper) / linear advance (Marlin) supported?Not documentedPressure advance, with automatic flow compensation calibration[2]
Extruder
Type (direct drive / bowden) & design nameDirect drive ("short distance extrusion") with hardened-steel extruder gears, which Anycubic rates at six times the life of brass on carbon-fibre filament[1]Not documented
Hotend & Nozzle
Hotend design (proprietary/standard; quick-swap mechanism?)Quick-release hotend with a titanium-alloy throat tube; 0.4 mm and 0.6 mm nozzles supplied, 0.25 and 0.8 mm optional; hardened steel[1]Not documented
Max nozzle temp claimed AND firmware max temp limit (both values)350 C maximum nozzle temperature[1]300 °C maximum (manufacturer claim)[2]
Stock nozzle material (brass / hardened steel / plated copper / composite tip)Not documentedStainless steel as standard; hardened steel needed for fibre-filled grades[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit120 C maximum hotbed temperature on a PEI spring steel build plate[1]100 °C maximum (manufacturer claim)[2]
Bed surface (material, texture, coating), single/double-sidedNot documentedFlexible steel sheet with a PEI surface[2]
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)LeviQ 3.0 auto-levelling[1]Mesh bed levelling. Automatic toolhead offset calibration is done by coordinate measuring[2]
Filament Handling & Detection
Filament runout sensor (type, location)Filament detection with auto resume, entanglement detection and power-loss resume[1]Filament run-out detection, plus air-printing detection and RFID filament recognition[2]
Multi-material/multi-color capability or official upgrade pathUp to 16-colour printing with ACE 2 Pro units, sold separately[1]Four toolheads with auto-feed and a backup mode; toolhead swap error detection, build-plate presence and obstruction detection[2]
Cooling & Air Handling

Materials Support
Officially supported filament listConsumer grades: PLA, PETG, TPU (95A), TPU for ACE, PET, PLA-CF, PETG-CF, PVA. Engineering grades: ABS, ASA, PC, PA, PA6-CF, PC-CF/GF, PET-CF[1]Base: PLA, PETG, TPU, PVA, PCTG. With the optional top cover: adds PET, ABS, ASA, PA, PC. With top cover and a hardened-steel nozzle: adds carbon- and glass-fibre-reinforced polymers[2]
Noise & Power Consumption
Noise: claimed dB and independently measured dB (distance/method)48 dB or less in standard mode, as low as 45 dB in quiet 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[5]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.
