Prusa CORE One+ (Gen 2) INDX 8-Tool 3D Printer

The CORE One+ (Gen 2) is Prusa doing what Prusa does: taking an already sensible enclosed CoreXY machine and quietly sharpening it rather than reinventing it. The headline here isn't the printer itself so much as the optional INDX toolchanger, which pushes it to eight materials in a single print — territory that, until recently, meant either an expensive industrial system or a wall of wasted purge filament.

With a 55 °C actively controlled chamber, this is squarely aimed at people printing ASA, PC and nylon rather than decorative PLA trinkets, and the multi-tool angle suits engineering prototypes with mixed supports, soluble interfaces or functional multi-material assemblies. At $2,082 assembled (or $1,805 as a kit), it lands in the serious-hobbyist and small-studio bracket. Note that the camera, advanced filtration and extra print sheets are all extras, so the real spend is higher than the sticker suggests.

Worth being clear about one thing: the two build-volume figures floating around for this generation don't quite agree, and Prusa's own listing is the more conservative of the two. Either way, it's a usable but not generous envelope for the money.

Judged on the evidence available, this is a strong machine with a specific personality. Prusa's claim of near-zero waste toolchanges is the genuinely interesting part — multi-material printing has historically been a filament bonfire, and a toolchanger sidesteps that in a way purge-based systems can't. Independent testing backs up the reliability story, with a three-week run reported without a misprint, and the offline-capable, fully repairable design remains a real differentiator in a market drifting toward cloud dependency.

The caveats are equally concrete. Recalibration is reportedly lengthy, there's a learning curve that eight tools only steepens, and the bed is small relative to the price — you're buying colour and material flexibility, not scale. Hardened hot ends weren't available at the time of independent review, which matters if abrasive composites are on your roadmap. The Gen 2 changes themselves (nozzle wiper, finer-pitch belts, revised heatbed mount) read as sensible refinement rather than a reason to upgrade from a working CORE One.

I'd also flag that we haven't been given figures for print speed, accuracy, noise or power draw, so this rating reflects capability and the weight of third-party reliability findings rather than our own bench numbers. A 4 feels right: excellent at its niche, priced accordingly, and not the machine to buy if you want to press one button and walk away.
