Prusa INDX Orders Are Open – But the Price Has Jumped $250 From Formnext Estimate
The wait is over but, important to note, what's now available is more than previously shown, with faster calibration tech and massive material savings at nozzle priming. It also sold out near-immediately, so you may be in for a wait before you can get one.
Prusa Research opened orders on April 23 for the INDX Conversion Kit for the Core One and Core One+ 3D printers. The 4-tool “starter kit” version is $749 in the US (tariffs included) and €669 in Europe (VAT included); the 8-tool variant runs $999 and €899 respectively. Shipping starts in June, with first-batch deliveries committed by end of August. The parallel Bondtech Founders Edition – a limited run of 1,200 units available last November – begins shipping at the start of May.
A blog post detailing the release indicates further products in Prusa’s INDX ecosystem will launch later in the year, including a 4 to 8-tool upgrade, INDX Conversion Kits for the Core One L, as well as preassembled printers that include preinstalled INDX systems. When exactly has yet to be determined.
Learning lessons from its past, perhaps, Prusa has tied the launch availability to production capacity. Only a finite number were made available on Friday, promptly selling out over the weekend. Right now, you can leave the company your email address to be notified when more are in stock.
The INDX comes as an upgrade kit, replacing the Core One’s Nextruder with a single active Smart Head that inductively heats passive nozzle tools on pickup. Each tool stays permanently loaded with its own filament, eliminating the need to purge at material change and, more significantly, the wipe tower entirely. Delivering on a promise made at the reveal to take the system further in eliminating waste, Prusa claims only 13 milligrams (0.013 g) of priming material per swap is lost – roughly five times less waste than the most efficient competing systems, they say. In terms of physical volume, this material waste is equivalent to less than a grain of rice.
Calibration has also been redesigned, with the original plan of using a Prusa XL-style bed-mounted pin ditched in for a dual-target eddy-current sensing station fixed outside the print area. The company says this cuts per-tool calibration time to approximately 15 seconds from the several hundred the earlier approach required.
Coinciding with the release is the news that FullSpectrum – a filament blending technique that originated in the community as a Snapmaker OrcaSlicer fork (we tried it – it’s great) – is making its way to PrusaSlicer and EasyPrint. To go with it, the company will launching a matching Prusament CMY filament set – a nod toward the new system’s baseline of being able to print cleanly with four filaments. Rather than being capped at four discrete materials, the kit can produce a wide range of pseudo colors, alternating layers between colors to give the illusion of an all-new filament hue.
Price Hikes for a Better System?
There’s a small gap between the system first shown, and what’s available for preorder now. Community pricing expectations after Formnext settled around $499/$699 for 4T/8T, grounded from statements at the INDX for Core One unveiling. Launching at $749 and $999, respectively, that’s a $250-300 increase. The company attributes it partly to the changed landscape around tariffs, though the point does remain that there are many material differences between what was first shown at Formnext, and what will be shipping in June.
The Founders Edition, a 1,200-unit first run, was scooped up in mere hours back in November last year and slated for delivery late Q1 2026. Those units are now expected to ship in early May. The main tech carries through between editions, though there are minor differences between the Founders Edition and the regular edition, chiefly a redesigned front plate for better visibility, plus other plastic parts. Prusa will make these parts available separately to FE owners who want to align their machine with the final release.
If you make the conversion to an INDX-equipped Core One+, expect your build volume to shrink slightly – 2 mm off the X axis, and 15 mm off the Y axis, leaving the printer at a total post-conversion volume of 248 x 205 x 270 mm. This is divergence from the initial showing of the system, which claimed there’d be no change to the build volume.
Owners of the original Core One don’t have to upgrade their machine to be a Core One+ before getting the INDX conversion kit – the necessary upgrades, such as the automatic ventilation grill parts, are included. Other parts, like the TPU filament tension switch, are made redundant by the INDX, and so are leapfrogged by the upgrade.
Buyers committing to Core One+ plus the 4-tool kit are looking at roughly $2,048 for both, putting the system close to Bambu Lab H2C territory. The H2C ships assembled with a substantially larger build volume; the INDX counters with near-zero purge waste, contributing largely to a speed advantage. If there’s anything our reader polls about the INDX have shown since it was unveiled, there is a committed base out there for it. Of those interested in it, over 60% were all-in on ordering – is that still the case?
