Anycubic Kobra vs Vyper

Last Updated: January 28th, 2023

The Anycubic Kobra is their new feature-packed printer that outperforms other Ender 3 alternatives and rivals the Artillery Genius and Prusa MK3S. In relation to the Anycubic Vyper, the Kobra is 29% smaller in build volume and only has a single z-axis, but it is cheaper and has a direct drive extruder.

Overall, we recommend the Anycubic Kobra for most users. It is by far the best bang for buck going into 2023. The Vyper outperforms only on build volume.

The Vyper has reports that the strain gauge leveling is prone to being damaged and needing replaced.

Anycubic Kobra and Anycubic Vyper

  • Both printers use a PEI coated spring steel sheet as the print surface.
  • Both printers come with a touch screen control interface.
  • Both printers do not have an all-metal hotend, which means that the PTFE tube will begin to off-gas above 230°C. It is recommended to replace the heatbreak or hotend if you want to print at higher temperatures.
  • What filaments can they print at 260°C? PLA, PETG, ABS, ASA, PP and flexibles like TPU.
  • Both printers can be connected locally via SD Card and networked over USB. The Kobra uses Micro-SD, while the Vyper uses regular SD cards.

Anycubic Kobra

  • The Anycubic Kobra comes with a build volume of 220x220x250mm.
  • The Anycubic Kobra has a direct drive extruder, which provides a higher level of reliability with retractions and flexible filament.
  • The Anycubic Kobra has a single z-axis.
  • The Anycubic Kobra uses an induction probe for auto-leveling.

The Anycubic Kobra arrives mostly assembled and is securely packed with foam. The assembly should take 15-30 minutes. It involves attaching the vertical frame, mounting the control display, securing the filament holder to the top of the frame, connecting the electronics, and adding a wire clamp. 

After leveling, we started a print and found that a z-offset of -1.9 was ideal for our printer. We started a complex hexagonal mesh print, and the Kobra printed flawlessly.

Thermal imaging revealed that the south-west section of the bed had a hotspot, but the entire bed stayed within 55-61°C. This was at a target temperature of 60°C and with letting it preheat for about 5 minutes.

The main downside is that a smooth PEI spring steel sheet is not included or available through Anycubic. The one included is textured, so a smooth plate will need to be purchased from a third party.

Parts that are included with the Kobra are a microSD card plus adapter, USB Type B cable, spare nozzle, spare PTFE tube, plastic scraper, open-ended wrench, hex key set, micro cutter, flat head screwdriver, nozzle-clearing needle, lubrication grease, and 10 meters of filament.

Anycubic Vyper

  • The Anycubic Vyper comes with a build volume of 245x245x260mm, which is 29% larger than the Kobra.
  • The Anycubic Vyper has a bowden extruder, which is ideal for faster print speeds due to the lower weight.
  • The Anycubic Vyper will have more stability with its dual z-axis.
  • The Anycubic Vyper uses the nozzle and an internal strain gauge for auto-leveling, and will need to be replaced if you swap the hotend.

1 - Dupont's maximum service temperature for PTFE is 260°C, but documentation notes that PTFE begins to decompose at 230°C. The decomposition rate at 260°C is 2 to 20 times higher than at 230°C, and we recommend using 230°C as a safety limit if you do not have adequate ventilation or filtration.

Final Thoughts

Between the two printers, we would recommend the Kobra for most users. The Vyper would only be necessary for its additional build volume or speed capability. The Kobra should prove to be a better pick than the other Ender alternatives such as the Neptune 2 and Artillery Hornet.
