Identity
BrandAnycubicRat Rig
ClassBEDSLINGERCOREXY
Identity & Market
Manufacturer & exact marketed model name (verify the exact product identity first)Anycubic Vyper[1]Rat Rig V-Core 4.1, described by Rat Rig as a large-format open CoreXY 3D printer kit[2]
Release date (announcement and actual shipping)Listed on the Anycubic store from 22 May 2021 (Shopify publish date)[1]Not documented
Street price (USD; dated snapshot per entry)$359.00 on store.anycubic.com, Aug 2026, with the compare-at price also $359.00 (no discount running) - notably more than the newer and much faster Kobra 2 at $169[1][3]Not documented
Variants & sibling models — and how to tell them apart (spec-contamination risk)A 2021-generation machine still on sale next to the far faster Kobra line. Its defining differences from every Kobra here: a Bowden extruder rather than direct drive, a 180 mm/s ceiling rather than 300-600 mm/s, and 16-point levelling rather than LeviQ 2.0/3.0. Do not read Kobra performance figures onto it[1][3][4]Three sizes, all at the same base-kit price. Acceleration is the size-dependent figure and the one most often mis-quoted: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm. IDEX is a configuration option and changes the usable area per toolhead (copy mode 150x150x300 at the 300 size, mirror mode 95x95x300). Base kit excludes electronics. Rat Rig prices the base kit only in EUR (EUR 873.90 on sale from EUR 971.00, Aug 2026); no USD list price is published, so no USD street price is recorded here[2]
Market position: superseded? successor announced?Effectively superseded by the Kobra line, but still listed for sale on the Anycubic store in Aug 2026[1]Current revision, replacing the V-Core 4; Rat Rig sells a 4.1 upgrade kit for existing V-Core 4 machines[2]
Physical & Frame
Build volume X×Y×Z (mm) — advertised vs actually usable260 x 245 x 245 mm stated as HWD, i.e. 245 x 245 x 260 mm in the usual X x Y x Z order; Anycubic quotes a 15.6 L build volume[1]300 x 300 x 300, 400 x 400 x 400 or 500 x 500 x 500 mm. Sortable value is the 300 mm kit[2]
Machine footprint (mm) & clearance needed (cable/spool overhang)516 x 508 x 457 mm stated as HWD, so the desk footprint is about 508 x 457 mm[1]623.2 x 583 x 785 mm (300); 723.2 x 683 x 885 mm (400); 823.2 x 783 x 985 mm (500). Sortable value is the 300 mm kit[2]
Net weight (kg)10 kg[1]Kit weight 35 kg (300), 45 kg (400), 55 kg (500)[2]
Frame construction & materialNot documented30-series aluminium extrusion; the 4.1 adds a steel X-axis gantry for rigidity[2]
Enclosure: open / enclosed; panel material; door/lidOpen frame, no enclosure[1]Open frame in the base kit[2]
Kinematics & Motion Hardware
Kinematics (bedslinger i3 / CoreXY / other)Cartesian bed-slinger[1]CoreXY; Hybrid CoreXY and IDEX are configuration options[2]
Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?)TMC2209 silent drivers on a 32-bit mainboard with a Cortex-M3 class main control chip - one of the few Anycubic machines where the driver part number is published[1]Not documented
Speed & Acceleration
Max print speed (claimed, mm/s)180 mm/s maximum print speed with 80 mm/s recommended (manufacturer figures)[1]Not documented
Recommended/typical print speed80 mm/s typical/recommended print speed (manufacturer figure)[1]Not documented
Max acceleration (claimed, mm/s²)Not documentedSize-dependent: 15,000 mm/s2 at 300 mm, 12,000 at 400 mm, 8,000 at 500 mm (manufacturer claims)[2]
Extruder
Type (direct drive / bowden) & design nameAnycubic's own Bowden extruder - not direct drive[1]Full-metal skeleton toolhead, new in the 4.1[2]
Hotend & Nozzle
Max nozzle temp claimed AND firmware max temp limit (both values)260 C operational nozzle temperature ceiling[1]350 °C maximum nozzle temperature (manufacturer claim)[2]
Stock nozzle size & sizes included in boxNot documented0.4 mm hardened steel and 0.6 mm included[2]
Heated Bed & Surface
Max bed temp claimed AND firmware limit110 C operational hot bed temperature ceiling[1]120 °C maximum heatbed temperature (manufacturer claim). The 400 and 500 sizes get 8 mm thick beds in the 4.1[2]
Bed surface (material, texture, coating), single/double-sidedPEI-coated stainless spring steel magnetic flexible platform, chosen by Anycubic over carborundum glass to avoid arching[1]Not documented
Leveling & Z-Offset
Auto bed leveling: probe technology (inductive / strain gauge / load cell / touch probe)16-point automatic levelling[1]Not documented
Cooling & Air Handling
Part-cooling fan(s): count, size, ducting designNot documentedImproved part cooling, listed by Rat Rig as one of the 4.1 changes[2]
Electronics & Power
Total rated power draw100-240 V AC 50/60 Hz input; 24 V / 14.6 A (350 W) output[1]Not documented
Firmware & Openness
Firmware base & current version (Klipper fork / Marlin fork / proprietary)Not documentedRatOS 2.1 (Rat Rig's Klipper distribution)[2]
Connectivity, UI & Camera
Display: size, type, touch?4.3-inch LCD touch-control screen[1]Not documented
WiFi (band/standard), Ethernet, USB ports, SD/flash-driveTransFlash (microSD) card; USB cable connection is flagged by Anycubic as being for expert users only[1]Not documented
Calibration Routines & QoL
Assembly level & time from unbox to first printModular design with 4 major pre-assembled modules[1]Self-assembly kit; the 4.1 ships pre-made cables that need no crimping, with rewritten step-by-step build documentation[2]
Materials Support
Officially supported filament listPLA, ABS, PETG, TPU and wood-filled filament[1]PLA, PETG, ABS, ASA, TPU, PET, PA, PC, PVA, PLA-CF, PETG-CF, ABS-GF, ASA-CF, PA6-CF, PA6-GF, PAHT-CF, PPA-CF, PET-CF[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[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.
