What Are the Differences Between Kobra, Kobra Plus and Kobra Max?
1. Build Volume
The 3D printer's build volume is the maximum size of objects that the printer can produce. Anycubic Kobra Max is an extra-large format 3D printer, which is great for printing large-sized objects and projects required large assemblies. The dimensions of Kobra Max's workspace are 400 x 400 x 450mm, which is approximately equivalent to the size of two 16-inch car wheel hubs. While Kobra is the smallest format printer in the Kobra series.
2. Extrusion System
All three models have a single extruder but with different extrusion systems. Only Anycubic Kobra is equipped with a direct drive extruder, while the other two have Bowden-separated extruders. When selecting a printer, you should understand that different systems have their own pros and cons, which mainly depend on personal preference.
3. Build Plate
The build plates of Anycubic Kobra Plus and Kobra Max are carborundum glass, while Kobra uses a PEI metal and magnetic sheet. Many makers who prefer traditional glass material as a build surface appreciate its ability to produce a smooth bottom surface for the printed parts. On the other hand, the PEI magnetic sheet becomes popular in recent years due to its flexible and magnetic properties, which greatly enhance the printing experience. Because it is magnetic, it can be easily removed or firmly attached to the heated bed. Additionally, being a flexible build sheet, users can effortlessly remove printed parts by slightly bending the plate, allowing the printed objects to easily pop out.
4. Z-Axis Thread Rod
A Z-axis threaded rod is rotated by a stepper motor to make the print platform raise or lower, thus building three-dimensional objects. As Kobra Plus and Kobra Max are large format printers, they feature two threaded rods and two motors for the Z-axis to ensure printing stability and precision.
5. Filament Sensor
A filament sensor is one of the components on 3D printers that can detect if the material is running out during printing. Once it monitors that the filament is using up, it can automatically pause the printing process to avoid print failures or wasting materials. Both Kobra Plus and Kobra Max come with this sensor as standard equipment, while Kobra offers it as an optional function. But Kobra users can have this feature by purchasing the accessory separately and configuring it on the printer if needed.
What Are the Similarities Between Kobra, Kobra Plus and Kobra Max?
1. Auto Bed Leveling
The current models in Anycubic Kobra series boast a self-developed smart leveling system, Anycubic LeviQ. To solve the print bed's unevenness, these machines are able to perform precise calibration through a 25-point automatic leveling process. In comparison to traditional manual bed leveling, Anycubic LeviQ automatic leveling system helps improve print accuracy and consistency while providing a simple operation and an enhanced printing experience.
2. Module Assembly
The three printers have been modularly designed for fast assembly, which will reduce the chances of assembly errors leading to machine malfunctions. For example, Anycubic Kobra can be assembled within ten minutes of unboxing by following the instructions provided. Indeed, this design helps reduce the learning curve and entry barrier for many beginners in FDM 3D printing.
Which One is Right for You?
- Anycubic Kobra: Affordable 3D printer for beginners
- Anycubic Kobra Plus: Large format 3D printer for beginners and expert
- Anycubic Kobra Max: Extra-large format 3D printer for expert
These three models are all easy-to-use machines with an automatic bed leveling function. However, the question of which one is right for you mainly depends on individual needs. Kobra model is positioned as an entry-level small format printer, and benefits from ease of operation and great value for money. On the other hand, large build volume printers always attract many enthusiasts' attention, making Kobra Plus and Kobra Max more suitable for experienced users who have experience with 3D printing.
Moreover, it is highly recommended to use Kobra series printers along with Anycubic's filament, for the reason that they offer high compatibility and can produce higher-quality prints. Finally, subscribe to Anycubic's official website as they will frequently hold promotional activities, and you can usually get the machine you desire at a favorable price.
