Filament compatibility for the Anycubic Kobra 4: the materials Anycubic lists for it. | Filament | Suitability | Notes | | :--- | :--- | :--- | | PLA | Great | On the maker's list of materials for this printer. | | PETG | Great | On the maker's list of materials for this printer. | | TPU & flexibles | Great | On the maker's list of materials for this printer. | | ABS & ASA | With care | The bed is hot enough, but ABS and ASA warp without an enclosure, which is strongly recommended for clean prints. | | Nylon (PA) | With care | Possible with care - an enclosure and very dry filament are essential. | | Polycarbonate (PC) | With care | On the edge - PC really wants an enclosed, hot chamber to avoid warping. | | Carbon-fiber & glass-filled | With care | Possible if you fit a hardened or wear-resistant nozzle - the abrasive fibers quickly wear a stock brass nozzle. | ## What reviewers say about the Anycubic Kobra 4 - [Anycubic Kobra 4 Combo 3D printer review: Evolution, not revolution](https://www.tomshardware.com/3d-printing/anycubic-kobra-4-combo-3d-printer-review) (Tom's Hardware, June 22, 2026, 4/5): Tested an early-production Kobra 4 Combo with the ACE 2 Pro and calls it an updated Kobra 3 with A1-style looks. Likes the quick-swap high-flow hardened nozzle, quick assembly, quiet running and better colour handling. Dislikes slow filament swaps, wasteful purging, the large footprint and awkward TPU. Subtitle: did the Kobra X do it better? Probably. > "It doesn’t do much to move the needle when compared to its brethren, but it's a solid machine and a good value." - Denise Bertacchi, Tom's Hardware ## When to choose the Anycubic Kobra 4 Choose the Kobra 4 when you want an easy, quiet printer at a low price and mostly print PLA and PETG: Tom's Hardware, testing the Combo, called it a solid machine and good value, though an evolution of the Kobra 3 more than a leap. Choose the Combo for colour, but note Tom's Hardware found filament swaps slow and purging wasteful. If you need ABS or ASA or a closed chamber, pick an enclosed printer such as the Bambu Lab P2S or Creality K2; if you want a larger plate, the Kobra 3 Max V2 Combo is bigger. ### Pros - Quiet: Anycubic gives 48 dB in standard mode and 45 dB in silent mode, and Tom's Hardware also found it quiet. - Quick assembly, about 15 minutes by Anycubic's claim, and a quick-swap high-flow hardened nozzle (Tom's Hardware). - A built-in 720p camera with spaghetti and foreign-object detection, plus time-lapse and an app (Anycubic). - The Combo adds the ACE 2 Pro for four colours (up to eight with two units) and better colour handling (Tom's Hardware, Anycubic). - Tom's Hardware rated the Combo 4/5 and a good value. ### Cons - Open frame with no enclosure, so it is best kept to PLA, PETG and TPU. - Filament swaps with the ACE 2 Pro are slow and purging is wasteful, and TPU is awkward (Tom's Hardware). - A large footprint for a 260 mm printer (Tom's Hardware). - We have not confirmed how it connects to SimplyPrint; Klipper is ruled out and OctoPrint unlikely, so check before buying for a fleet. ### Who it suits - Schools: Can work. Quiet and easy to set up, with a camera, but open and without confirmed SimplyPrint support, so queueing student prints for approval is not assured. - Hobbyists: Good fit. Quiet, quick to set up and good value, with an optional four-colour Combo; it is more evolution than revolution (Tom's Hardware). - Businesses: Can work. Good for PLA and PETG prototypes, but open, with slow colour changes and no confirmed SimplyPrint route. - Print farms: Not a good fit. SimplyPrint compatibility is unconfirmed and it has no enclosure or plate-clearing kit in our sources. ## Printers like the Anycubic Kobra 4 that work with SimplyPrint - [Anycubic Kobra X](https://simplyprint.io/compatibility/anycubic-kobra-x): Compatible, 260 x 260 x 260 mm, Also by Anycubic · Similar build volume · Multi-material too - [Anycubic Kobra 3 Combo](https://simplyprint.io/compatibility/anycubic-kobra-3-combo): Compatible, 250 x 250 x 260 mm, Also by Anycubic · Similar build volume · Multi-material too - [Prusa MK4S](https://simplyprint.io/compatibility/prusa-mk4s): Compatible, 250 x 210 x 220 mm, Similar build volume · Multi-material too - [Creality Hi Combo](https://simplyprint.io/compatibility/creality-hi-combo): Compatible, 260 x 260 x 300 mm, Similar build volume · Multi-material too ## Where to buy the Anycubic Kobra 4 - [Anycubic for the US](https://simplyprint.io/buy/8248) (Official store) (Affiliate link): $199.00 (Price at Anycubic, checked October 23, 2026) - [Anycubic's global store](https://simplyprint.io/buy/8247) (Official store) (Affiliate link): $279.00 (Price at Anycubic, checked October 23, 2026) - [View at TECBEARS](https://simplyprint.io/buy/8249) (Affiliate link) - [Anycubic Kobra 4 Combo](https://simplyprint.io/compatibility/anycubic-kobra-4-combo): Also sold as the Combo, with its multi-material unit. ## About Anycubic Anycubic is a Chinese 3D printer maker founded in 2015. It sells the Kobra line of FDM printers, including the enclosed Kobra S1 and S1 Max, the large Kobra 3 Max and the low-cost Kobra X, the ACE Pro multi-material unit and Photon resin printers. Its printers are aimed at hobbyists and home users at budget to mid-range prices. - Founded: 2015 - Headquarters: China (its global store is run by Hongkong Anycubic Technology Co., Limited) - Website: https://www.anycubic.com Openness: Mixed (3.0 of 5) Anycubic is mixed: its printers work locally in LAN mode, take third-party filament and slicers, and have spare parts and guides, but its published firmware source leaves proprietary parts closed, custom firmware is unsupported, and its cloud had a security incident in 2024. - Firmware and custom firmware (3 of 5): The Kobra 3, 3 Max and S1 run Klipper-go, Anycubic's Go port of Klipper. Anycubic published its source with the kernel and U-Boot under GPL, for the Kobra 3 in October 2024 and for the wider family in October 2025, but says some proprietary features are kept closed, and that modifying the firmware voids the warranty. The community project Rinkhals adds Fluidd, Mainsail and SSH, and reports that the newer Kobra X only accepts signed updates. - Local control and integrations (3 of 5): LAN mode lets Anycubic Slicer Next send prints, show progress and stream video on the local network without an account, and the S1's firmware 2.5.9.9 added sending from OrcaSlicer. With LAN mode on, the cloud, the app and AI failure detection are off, and the S1 must leave LAN mode and be bound to an account to update its firmware. Anycubic documents no local API for other software; Moonraker, Fluidd and Mainsail come only with the community firmware Rinkhals. - Third-party filament, slicers and parts (3 of 5): Third-party filament works. Anycubic Slicer Next is an open-source OrcaSlicer fork, and recent firmware accepts files sent from OrcaSlicer. Hotends, extruders and many other parts are model-specific Anycubic parts. - Repairs and spare parts (4 of 5): Anycubic's store sells hotends, extruders, motherboards, heated beds, motors and screens, and its wiki has replacement guides for current models, for example the Kobra S1 Max XY motors and the Kobra X Y-axis motor. - Data and privacy (2 of 5): LAN mode keeps data on the local network, but the app and cloud need an account. Anycubic's privacy policy allows broad collection, including product usage, device signals and nearby Wi-Fi access points, and storage in the United States. In February 2024 a flaw in its cloud MQTT server let a third party push a file to Kobra 2 printers; Anycubic apologised and patched it. - Community and documentation (3 of 5): Active user community and a wiki with guides and error codes for each model. Source releases leave proprietary parts closed, and custom firmware is a community effort. ### Pros - Budget to mid-range prices, with multi-colour Combo bundles. - LAN mode works without an account. - Spare parts and replacement guides for current models. - Open-source slicer, and third-party filament works. ### Cons - Published firmware source leaves some features closed; modifying firmware voids the warranty. - LAN mode turns off the app, cloud and AI failure detection, and firmware updates need the cloud. - The privacy policy allows broad data collection. - Its cloud was used to push files to printers in 2024 (fixed). ### Track record - October 2025: Anycubic published Klipper-go, its Go port of Klipper, as a standalone project for the Kobra 3, Kobra 3 V2, Kobra 3 Max and Kobra S1, with the MCU firmware, Linux kernel and U-Boot sources, on GitHub under GPL-3.0. It says some proprietary features remain closed. - October 2024: Anycubic published the Kobra 3 firmware sources (Klipper-go, MCU firmware, Linux kernel and U-Boot) on GitHub under GPL-3.0. - February 2024: A third party used a vulnerability in Anycubic's cloud MQTT server to make Kobra 2 Pro/Plus/Max printers download a file named 'hacked_machine_readme.gcode'. Anycubic counted 237 affected printers and over 2,000 that received the file, apologised for its late response, tightened cloud authorisation and released a firmware fix.
