Anycubic Kobra 3 vs Prusa Research CORE One+

The Anycubic Kobra 3 and Prusa Research CORE One+ are both prosumer-tier printers, but the CORE One+ costs 2.9ร— as much โ€” so the question is what the extra money buys. Note that the Kobra 3 has been replaced by the Kobra 4 and is no longer sold new. The CORE One+ costs $650 more and gets you an enclosed chamber (with ASA, PA and PC on its materials list) and an open-source design; the Kobra 3 answers with 14% more build volume.

Cross-ecosystem comparison: These printers use different software ecosystems. Accessories, filament profiles, and community support are not interchangeable between brands. Consider the total ecosystem cost, not just the printer price.

Timing: When to Buy

The Kobra 3 has been replaced by the Kobra 4 and is no longer sold new, so there is no release cycle left to time โ€” any unit you find now is leftover or second-hand stock.

The CORE One+ was released on Aug 13, 2026, 91 days ago. Its previous release cycle ran about 209 days, so it is 44% of the way through โ€” roughly 118 days before a successor would be due at that pace.

On timing alone, the CORE One+ is the safer buy right now โ€” it is only 44% of the way through its expected cycle, while the Kobra 3 has already been replaced by the Kobra 4.

Deals & Pricing

The Kobra 3 lists at $349 and the CORE One+ at $999 โ€” $650 apart, so the CORE One+ costs 186% more.

Per litre of build volume, that works out to $21 for the Kobra 3 versus $67 for the CORE One+ โ€” the Kobra 3 is both cheaper and roomier, so it wins on value outright.

  • Kobra 3: No longer sold new, so there is no sale calendar to track โ€” judge any listing against the Kobra 4's $379 list price.
  • CORE One+: Prusa does not take part in Black Friday or Prime Day sales, so the $999 list price is what you will pay โ€” there is no sale to wait for.

Who Should Choose Each

Choose the Anycubic Kobra 3 ifโ€ฆ

  • you find it at a clearance price โ€” it is no longer sold new, and the Kobra 4 is its replacement
  • you want to spend less โ€” it is $650 cheaper ($349 vs $999)
  • you print large parts โ€” its 255 ร— 255 ร— 260 mm build volume holds 14% more than the CORE One+'s 250 ร— 220 ร— 270 mm

Choose the Prusa Research CORE One+ ifโ€ฆ

  • you want our higher-rated printer โ€” 9.0 vs 8.1 out of 10
  • you want to print ASA, PA and PC โ€” it is enclosed and lists them, while the Kobra 3 is open-frame
  • you are buying now โ€” it is the safer pick on timing (early in cycle, vs superseded for the Kobra 3)
  • you want an open-source printer you can modify and repair yourself โ€” the Kobra 3 is not open source
  • you want more colors or materials per print โ€” 8 slots vs 4
  • you are coming from the MK4S โ€” Prusa Research sells an upgrade kit to CORE One+ spec

Our Take

Buy the CORE One+. The Kobra 3 has already been replaced by the Kobra 4 and is no longer sold new, so it is only worth considering at a clearance price. If the Kobra 3 appealed to you, the fair comparison today is the CORE One+ against the Kobra 4.

Why buy each?

Anycubic Kobra 3

34% more build volume over original

The V2 expands to 255ร—255ร—260 mm โ€” 34% more printable volume than the original Kobra 3 โ€” for larger parts and more batch production.

AI monitoring camera included

The V2 includes a 720p camera for real-time print monitoring and AI spaghetti detection, adding reliability features previously absent from the Kobra 3 line.

4-color ACE Pro at budget pricing

The Kobra 3 V2 Combo with ACE Pro is one of the most affordable 4-color setups available โ€” often underpricing Bambu's A1 Combo.

Prusa Research CORE One+

Prusa's answer to Bambu P-series

The CORE One+ matches Bambu CoreXY speed (600 mm/s) while keeping everything open source โ€” firmware, hardware, slicing profiles.

Fully open source

Unlike Bambu's closed ecosystem, every component of the CORE One+ can be modified, repaired, or community-improved.

INDX toolchanger option

The CORE One+ (Gen 2) can be ordered with Prusa's INDX toolchanger in 4- or 8-tool versions, shipping from 15 October 2026. Each material gets its own nozzle, with about 12 seconds per material change and almost no purge waste. The MMU3 remains compatible as a 5-color add-on.
