| Class | BEDSLINGER | BEDSLINGER |
| Identity & Market | ||
| Manufacturer & exact marketed model name (verify the exact product identity first) | Anycubic Kobra 3 Combo - the Kobra 3 sold together with the ACE Pro filament unit[1] | Original Prusa i3 MK3S+. The only version still listed in Aug 2026 is the "Original Prusa i3 MK3S+ 10th Anniversary Edition"[2] |
| Release date (announcement and actual shipping) | Listed on the Anycubic store from 30 April 2024 (Shopify publish date)[3] | Not documented |
| Street price (USD; dated snapshot per entry) | $329.00 with a US plug on store.anycubic.com, Aug 2026 ($355.00 for the EU plug variant)[3] | $1,199.00 assembled, $899.00 as a kit, for the 10th Anniversary Edition on prusa3d.com, Aug 2026. This is above the price the standard MK3S+ sold at, so do not read it as the MK3S+ street price[2] |
| Variants & sibling models — and how to tell them apart (spec-contamination risk) | Two things to watch here. First, the Combo is printer plus ACE Pro; the ACE Pro alone weighs 4.6 kg and measures 366 x 283 x 235 mm, so plan bench space for both. Second, Anycubic's own specification table on this page mixes generations - the weight row reads "Kobra 3 V2 - 9.2kg" while the package row reads "Kobra 3 - 12kg", and a separate Kobra 3 V2 Combo product is listed at the same price. Treat any single figure from this page as needing confirmation against the exact SKU[1][3][4] | Only the 10th Anniversary Edition remains on sale; the standard MK3S+ is gone from Prusa's printer listing. Two official upgrade paths change the machine substantially and are frequently confused with it: MK3.5 (xBuddy board and new LCD, keeps the MK3 extruder) and MK3.9 (adds the Nextruder). A caution on Prusa's own pages: the "Awards & Press Reviews" paragraph about the MK3S is reproduced verbatim on the MINI+ product page, so award text found on a Prusa page does not necessarily belong to the printer on that page[2][5][6][7] |
| Market position: superseded? successor announced? | Not documented | Superseded by the MK4/MK4S line. Prusa cut MK3S+ prices at the MK4 launch in March 2023 and said it would keep selling the MK3S+ at a lower price and hold spare parts in stock[6][7] |
| Physical & Frame | ||
| Build volume X×Y×Z (mm) — advertised vs actually usable | 250 x 250 x 260 mm; Anycubic quotes a 16.25 L maximum printing volume[1] | 25 x 21 x 21 cm = 250 x 210 x 210 mm (manufacturer figure)[2] |
| Machine footprint (mm) & clearance needed (cable/spool overhang) | 452.9 x 504.7 x 483 mm for the printer; the ACE Pro is a separate 365.94 x 282.84 x 234.5 mm box[1] | 500 x 550 x 400 mm (X x Y x Z), without the spool holder[2] |
| Net weight (kg) | Anycubic's table gives "Kobra 3 V2 - 9.2kg" for the machine weight and "Kobra 3 - 12kg" for the package weight, plus 4.6 kg for the ACE Pro - the two rows do not refer to the same thing, so treat 9.2 kg as the machine and 12 kg as shipping weight[1] | 7 kg (without spool)[2] |
| Frame construction & material | Not documented | Cut aluminium frame - Prusa's MK4 announcement contrasts "the cut aluminum frame we used so far" with the MK4's new die-cast frame[6] |
| Enclosure: open / enclosed; panel material; door/lid | Open frame, no enclosure[1] | Open frame; the Original Prusa Enclosure is an optional separate product[6] |
| Kinematics & Motion Hardware | ||
| Kinematics (bedslinger i3 / CoreXY / other) | Anycubic's specification table gives the construction as "Gantry System" - it is a bed-slinger, not the CoreXY layout used by the Kobra S1 series[1][8] | Cartesian i3 bed-slinger. Prusa's MK4 announcement notes the MK3S+ Y-axis profiles and heatbed were among the few parts carried into the MK4[6] |
| Stepper drivers (exact model e.g. TMC2209; UART/SPI; sensorless homing?) | Not documented | Trinamic 2130 drivers at 256 microstepping on the EINSY RAMBo 8-bit board, co-developed with UltiMachine; sensorless homing on X and Y[2] |
| Speed & Acceleration | ||
| Max print speed (claimed, mm/s) | 600 mm/s maximum print speed (manufacturer claim), with 300 mm/s recommended[1] | Not documented |
| Recommended/typical print speed | 300 mm/s recommended print speed (manufacturer figure)[1] | Not documented |
| Max travel speed | Not documented | "200+ mm/s" max travel speed (manufacturer figure, no measurement basis given)[2] |
| Max acceleration (claimed, mm/s²) | 20000 mm/s2 maximum acceleration, 10000 mm/s2 recommended (manufacturer claims)[1] | Not documented |
| Extruder | ||
| Type (direct drive / bowden) & design name | Direct drive (Anycubic's term is "short distance extrusion")[1] | Direct drive with Bondtech gears and an E3D V6 hotend[2] |
| Hotend & Nozzle | ||
| Hotend design (proprietary/standard; quick-swap mechanism?) | 300 C quick-release hotend; 0.4 mm standard nozzle, expandable to 0.6 and 0.8 mm[1] | Not documented |
| Max nozzle temp claimed AND firmware max temp limit (both values) | 300 C maximum nozzle temperature (manufacturer figure)[1] | 300 C claimed max nozzle temperature[2] |
| Heated Bed & Surface | ||
| Max bed temp claimed AND firmware limit | 110 C maximum hotbed temperature on a PEI spring steel build plate[1] | 120 C max heatbed temperature[2] |
| Bed surface (material, texture, coating), single/double-sided | Not documented | Removable magnetic spring-steel sheets in several finishes; heatbed with cold-corner compensation[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] | SuperPINDA inductive probe (Prusa's temperature-drift-free replacement for the original PINDA), driving automatic mesh bed levelling and a self-test routine[2] |
| Filament Handling & Detection | ||
| Filament runout sensor (type, location) | Filament detection with auto resume, filament entanglement detection, nozzle clog detection and power-loss resume[1] | IR filament sensor built in, supporting filament auto-loading; the print pauses when filament runs out[2] |
| Multi-material/multi-color capability or official upgrade path | 4-colour printing with one ACE Pro, or up to 8 colours with two units[1] | Not documented |
| Electronics & Power | ||
| Mainboard model & MCU (exact chip markings if teardowns exist) | Not documented | EINSY RAMBo 8-bit board, co-developed with UltiMachine[2] |
| Input voltage (110/220 V, switch or auto) | Not documented | Custom Delta PSU with hardware-based power panic[2] |
| Total rated power draw | Not documented | Power consumption 80 W on PLA settings, 120 W on ABS settings[2] |
| Firmware & Openness | ||
| Firmware base & current version (Klipper fork / Marlin fork / proprietary) | Kobra OS. Anycubic's slicer, Anycubic Slicer Next, is stated to be built on the open-source Orca slicer[1] | prusa3d/Prusa-Firmware on GitHub, GPL-3.0, whose README states it is "proudly based on Marlin 1.0.x" and covers the MK3S/MK3/MK2.5S/MK2.5 line; last pushed August 2025. Updated over USB from a PC[9] |
| Connectivity, UI & Camera | ||
| Display: size, type, touch? | 4.3-inch capacitive touchscreen with a 30-60 degree adjustable tilt[1] | Not documented |
| On-device UI capabilities (model preview, per-object controls, etc.) | Touchscreen plus Anycubic Slicer Next, the Anycubic app and USB (print only); AI spaghetti detection and object skip are supported[1] | Not documented |
| WiFi (band/standard), Ethernet, USB ports, SD/flash-drive | Printer UI, slicing software, Anycubic app and USB drive (print only)[1] | SD card (16 GB card included); Ethernet and Wi-Fi only via an optional Raspberry Pi[2] |
| Camera: built-in / optional? Resolution & framerate (verify — marketing often omits real fps) | Camera is optional on the Kobra 3 - a 720p HD unit, not fitted as standard, unlike the Kobra S1, Kobra 4 and Kobra X[1][8][10] | Not documented |
| Materials Support | ||
| Officially supported filament list | PLA, PETG and TPU, and Anycubic notes TPU is not compatible with the ACE Pro multi-material unit[1] | PLA, PETG, ASA, ABS, PC, CPE, PVA/BVOH, PVB, HIPS, PP, Flex, nGen, Nylon, carbon-filled, woodfill and other filled materials[2] |
| Safety | ||
| Thermal runaway protection (verify in firmware source if at all possible) | Not documented | Prusa shipped Thermal Model protection to the MK3 line as a firmware update shortly before the MK4 launch; the firmware is open-source and auditable[6][9] |
| 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[11] | 2-year warranty for consumers in the EU, Liechtenstein, Switzerland, Norway and Iceland; 1 year for EU enterprises and 1 year for the rest of the world, which includes the United States. A printer bought from a reseller or privately carries 1 year from the original delivery date and is handled by the reseller. Prusa advertises 24/7 chat and e-mail support in seven languages[12][13] |
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.
