3D printer manufacturer, Anycubic, recently released two new printers—the Anycubic Kobra and its bigger, badder uncle, the Anycubic Kobra Max. We were interested in testing both products in our hunt for the best entry-level 3D printers. We’re looking for ease-of-use and affordability, as well as build and print quality. 

We’ve published a number of 3D printer reviews from Anycubic—for both FDM printers like the Anycubic Vyper that print with spools of filament and SLA resin 3D printers like the Anycubic Photon Mono X 6K that use a liquid resin as its raw material—and we can say that the Kobra Max has quickly become one of our favorites.

    Features of the Anycubic Kobra Max 3D Printer

    The most obvious feature of this printer is its size. It is absolutely massive. That means you can print huge items in a single piece. Think of a full helmet or an entire ukulele—these are things you couldn’t print in one piece on a normal-sized 3D printer. Truly, the word “Max” doesn’t sufficiently capture just how big this printer is. Good luck fitting the packaging into your trash or recycling bins!

    We were skeptical that a Cartesian printer of this size (which relies on a moveable print bed) would perform well since it has a lot of weight to move around. Admittedly, it’s not the speediest printer out there because of those design tradeoffs, but it works great.

    The Kobra Max has an impressive list of technical specifications:

    • Leveling: Automatic, 25 points leveling using the Anycubic Leviq technology
    • Panel area: 7.95 in² / 51.3 cm²
    • Filament run-out detection: support
    • Printing material: PLA / ABS / PETG & TPU
    • Nozzle size: ø 0.4 mm (replaceable)
    • Nozzle temperature: ≤ 500 °F / 260 °C
    • Hot bed temperature: ≤ 194 °F / 90 °C
    • Average speed: 3.1 – 3.9 in./s  (80mm/s – 100m/s)
    • Control panel: 4.3 inch LCD touch screen
    • Z-axis: double threaded rod
    • Print size: 17.7 x 15.7 x 15.7 in. / 45 x 40 x 40 cm (HWD)
    • Build volume: 19.02 gal. / 72.0 L
    • Machine dimensions: 72 x 71.5 x 66.5cm

    As far as we can tell, the extruder is identical to the extruder and print head on the Anycubic Vyper. Furthermore, the Kobra Max has the same automatic bed-leveling system as the Vyper. The system uses a pressure sensor instead of an inductive sensor.

    The bed-leveling sensor is right on the nozzle itself, ensuring that it can probe every printable part of the bed. And since the sensor is pressure-based, you could replace the glass bed with any other material and the bed-leveling system will still work. (Inductive sensors require metal to work, so you won’t find them on printers with glass beds.)

    Since the Kobra Max’s printing platform is a rigid glass sheet, you can’t remove and flex it to pop your prints off. We prefer removable spring steel build plates, but glass is still a nice printing surface. If your printer doesn’t have a removable bed, glass is ideal because you can use metal scrapers to remove your prints without worrying about scratching the surface.

    The LCD touchscreen is identical to the screens used on many other Anycubic printers.
    As usual, it’s responsive and easy to use. 

    A note about filament types: the Kobra Max will print with PLA, PETG, TPU, and ABS. However, if you really want to print with ABS and get the best possible results, the printer should be inside an enclosure. Given its size, it may be challenging to build a suitable enclosure for the Kobra Max. 

    Assembling the Kobra Max 3D Printer

    Review of Anycubic Kobra Max 3D Printer image 5

    When assembling the new Kobra Max, make sure you have sufficient working space.  Since the bed moves forward and backward, you need more space than you’d think. We put it on a 30” folding table, and when it’s printing, it needs about 36 inches, front to back.

    Assembly of the Kobra Max is no more difficult than assembling the Kobra or Vyper.  The only additional items are the diagonal braces which add stiffness to the frame, reducing mechanical vibration.

    It took two people about 15 minutes to assemble. Double-check that you’ve cut all the zip ties used to stabilize the printer during shipping. There are a lot of them.  

    Calibration 

    The auto-bed-leveling system is easy to use. Anycubic recommends that you check the x- and the y-axes to make sure they don’t wobble. If they do, you can adjust the eccentric nuts until the wobbling stops. There was no wobble on our printer, so we didn’t have to do anything.

    Additionally, the x- and y-axes have belt tensioners. We needed to slightly tighten the x-axis on ours. The tensioners are easy to use and are features a lot of other printers lack. Who wants to take apart the extruder assembly just to tighten the belts? Not us, and probably not you. 

    Build Quality of the Kobra Max

    Due to the addition of the diagonal braces, the frame is really stiff. The dual z-axis screws are an improvement over the smaller Kobra. They virtually eliminated sagging of the x-axis assembly.

    The spool holder sits on the base of the printer, reducing wobbling when printing tall items. It’s better than having the spool on the top like on the Kobra.

    This printer is built with aluminum extrusions with aesthetically-pleasing plastic covers for the hotend and the tenionsers. It’s got an optical z endstop. The x and y endstops are mechanical. The whole thing feels solid.

    First Print

    Review of Anycubic Kobra Max 3D Printer image 10

    For the first print, we used the test file provided by Anycubic. Appropriately, the owl is about twice the print volume of the owl test print that comes with the smaller Kobra. Given the bowden setup (which makes sense for a printer this size), we were surprised that the ears on the owl turned out so well. 

    The ears look better than they did on the owl printed on the Kobra which has a direct drive extruder system. We suspect that’s due to the slower print speed. Many times, retractions on bowden extruders will create artifacts, but we didn’t notice any blobs or stringing. It approaches the quality you’d expect from a direct-drive.

    Next, we printed a vase with a large, flat base with a 0.2mm layer height. Removing prints from the glass bed is certainly not as easy as removing prints from smaller, flexible beds, but it’s not a deal-breaker either. We didn’t have any adhesion problems. The prints didn’t release when the glass bed cooled, which is what we expected and hoped for. 

    Curious what the power requirements would be for a printer this size, we were worried we wouldn’t be able to run multiple printers on the same circuit.  We measured the power usage while the Kobra Max was printing, and, as expected, power usage is highest while the printer is warming up. Ours topped out at 473 watts. While printing, it was a more manageable 200-300 watts. We thought it would be more than that. You could probably run three of these printers on a 20 amp circuit.

    Cut to the Chase

    To drive home just how big the Kobra Max is, we put the Kobra on the bed of the Kobra Max. Insane. (We do not recommend you try this.)

    A small printer is limiting, so if you find yourself printing large objects in small pieces and assembling them, consider buying a Kobra Max. If you’re new to 3D printing, keep in mind that it takes a long time to print big objects—potentially days and days. Typically, we’d recommend a smaller printer to beginners, but at the price point of  $569.00 if you purchase on the Anycubic site, it’s worth considering as an entry-level printer.

    One downside is that smaller prints will take a little longer than they would on a smaller, faster printer. That’s just physics. Bigger printers have more inertia to overcome and take longer to move. For example, the print time for our vase was thirteen hours. On our Prusa MK 2.5 with similar settings, it would have taken about twelve hours—not a huge difference.

    Purchase the Anycubic Kobra Max on Amazon, AliExpress, or the Anycubic website.
