Prusa CORE One+ INDX 8-Tool Review: Eight-Filament 3D Printer Starts at $2,249

According to TechRadar, the machine took a little while to calibrate fully but then ran solidly for three weeks without a single misprint. The review lists eight-filament printing, 100 percent repairability and the ability to be used completely offline as advantages. It notes that recalibration can take a while, that the new way of working requires some thought, and that the print bed is small. TechRadar says that once hardened hot ends are available, the CORE One+ INDX will be the machine to beat.

The printer is based around the CORE One, which TechRadar says remains the most used and reliable 3D printer in its workshop. The original CORE One was reviewed in January 2025 as a significant update to the MK4S. Since then, Prusa has introduced the larger CORE One L and Plus upgrades to both machines, and the INDX system comes from Bondtech and Prusa Research. Externally, the CORE One+ INDX looks almost identical to the CORE One. The main body and build area are the same, and the eight reels on the outside are the clearest visual difference. The INDX system is bolted onto the front top of the machine. Its added dock covers the view to the platform and contains eight new toolheads, which are heated through induction rather than traditional wires and attach to a magnetic dock along the front.

TechRadar says buyers can choose a fully assembled machine or a kit, and that the kit can save almost $300 or £300 compared with the pre-assembled version. Owners of a CORE One or CORE One+ can buy an upgrade kit for $999 or £909 for the eight-tool version, and a four-toolhead version is also available. Prusa also offers other INDX conversion kits. The review says that, as with the first model, there is always an upgrade route to the latest version regardless of which Original Prusa machine a customer owns.

The eight-tool-changer printing is the main feature, but TechRadar says its potential becomes clearer when the machine is used alongside competitors such as the Bambu Lab H2C and the cheaper Snapmaker U1. The review calls the speed a significant upgrade over both. In a head-to-head five-color print, even though the H2C has a much larger print bed, the CORE One+ INDX had to complete the job in several batches and still produced substantially more models than the larger machine in less time. TechRadar says that, considering price, multi-filament reliability and speed, this is the best 3D printer it has ever tested, and that it makes other machines hard to recommend. The review adds that the CORE One L has now also been adapted to use the INDX system, which TechRadar says puts Prusa ahead in this scale of machine for projects from small to large.

TechRadar also reports that the four-tool kit can be bought assembled for less than £2,000 or $2,000, while the eight-tool set reviewed is a little over that amount. The review says Prusa sits at the heart of the open-source 3D printing community, and that its partnership with Bondtech has produced one of the finest machines on the market today.

Editor's Summary

TechRadar's review presents the Prusa CORE One+ (Gen 2) INDX 8-Tool as a fast and reliable eight-filament 3D printer, priced from $2,249 or £2,039 assembled and $1,949 or £1,769 as a kit, with shipping from October 15. The reviewer reports three weeks of misprint-free operation and says its multi-color speed beats the Bambu Lab H2C and Snapmaker U1 in a head-to-head test. Existing CORE One and CORE One+ owners can upgrade with an eight-tool kit priced at $999 or £909.
