Our take on the Prusa Research Original Prusa Core One 3D Printer

The Original Prusa Core One is Prusa Research's enclosed CoreXY 3D printer, a step up from the open-frame MK4S. It has a 250 x 220 x 270 mm build volume, a heated chamber, the Nextruder toolhead, input shaper tuning, a door sensor and a built-in camera. It prints PLA, PETG and ASA, and Prusa rates it for an 8-minute high-speed Benchy. The best new price is $2,077 at eBay as of November 6, 2026, with only one store listing it new.

Pros
  • Enclosed, heated chamber makes ASA and large ABS-style parts practical
  • CoreXY frame with input shaper gives fast, accurate motion
  • Nextruder toolhead with quick-swap nozzles and full loadcell probing
  • Built-in camera and door sensor for remote monitoring and safety
  • Ethernet, Wi-Fi and USB, plus PrusaSlicer and Prusa Connect support
  • Steel frame and Prusa's spare-parts ecosystem make it serviceable long term
Cons
  • $2,077 is a big jump over an open-frame MK4S kit
  • 22.5 kg and 415 x 444 x 555 mm take real bench space
  • Build volume is smaller than some cheaper CoreXY rivals
  • No AMS-style multi-color box in the box; multi-material needs an add-on
  • Enclosure panels and chamber heat add noise and warm-up time

What reviewers say

Owners treat the Core One as the enclosed Prusa they had been asking for: MK4-level print quality with ASA finally made easy. Most criticism centers on price and footprint rather than print results.

What people mention
  • Print qualityPraisedOwners report accurate, clean parts with the stock PrusaSlicer profiles.
  • EnclosurePraisedThe heated chamber is the main draw, making ASA and large parts far less prone to warping.
  • SpeedPraisedInput shaper lets it run fast without ringing, and the 8-minute Benchy claim holds up.
  • PriceCriticisedBuyers say it costs noticeably more than open-frame Prusa kits and several CoreXY competitors.
  • Size and weightCriticisedAt 22.5 kg and roughly 41 x 44 x 55 cm, it needs a sturdy, dedicated spot.
  • NoiseMixedQuieter than an open printer for some, but chamber fans and warm-up are audible.

Questions and answers

Is the Core One worth it over an MK4S?
If you print ASA or large flat parts, yes: the heated enclosure is the difference. For PLA and PETG only, an open MK4S costs much less.
What can it print?
PLA, PETG and ASA are the listed materials, and the heated chamber is aimed at ASA. Layer heights run from 0.05 to 0.30 mm.
How big is the build volume?
250 x 220 x 270 mm, slightly taller than the MK4 series. That is smaller than some cheaper CoreXY machines.
Does it do multi-color printing?
Not out of the box. Multi-material needs an add-on unit; the printer itself ships with one Nextruder.
What's in the box?
The assembled printer, a 3D printing handbook and the standard accessories. Filament is not included.
When is it cheapest?
The best new price seen is $2,077 at eBay as of November 6, 2026, and only one store lists it new, so discounts are rare. Watch for Prusa's own sales and kit bundles.
Where is the Prusa Research Original Prusa Core One 3D Printer cheapest?
At eBay, for $2,077.00, as of our latest check.
