The INDX conversion kit is a hardware add-on that turns a compatible Prusa CORE One or CORE One+ into a toolchanging printer.

As of April 2026, Prusa says the first batch is priced at $749 for the four-tool version and $999 for the eight-tool version, with EU pricing listed at 669€ and 899€, and shipping of the Prusa Edition upgrade kits starting in June 2026, in the launch announcement.

That headline number is only part of the spend. The checkout total can shift based on tool count, add-ons you choose to buy at the same time, and how Prusa handles taxes, duties, and tariffs for your delivery address. This is also a project purchase, since the kit involves hardware changes, calibration, and the option to keep spare nozzles and wear parts on hand if you are running multi-material jobs regularly.

Prusa Research and Bondtech sit at the center of the story, but the budget math touches PrusaSlicer profiles, firmware updates, filament storage, and shipping logistics. A buyer who already owns a compatible CORE One machine is paying for conversion hardware. A buyer who is still choosing a platform is weighing the kit against other multi-color and multi-material options that bundle different tradeoffs into their base machines.

Treat this as a per-kit hardware purchase, then layer in the costs that come from how many tools you want loaded, how you plan to store and dry multiple spools, and the way import handling is presented at checkout. The gap between a simple “kit only” order and an all-in order is driven more by the add-ons and the destination than by the checkout button itself.

How Much Does The Prusa INDX Conversion Kit Cost?

Jump to sections

• Launch coverage reports $749 and $999 in the US for the two kit variants, and the spread is $250 because $999 minus $749 equals $250, in reported launch pricing.
• One third-party report says the first kits will be delivered from June 2026 in a June 2026 delivery note.
• Prusa’s published returns policy references a return window of 60 days after delivery on its refunds and returns page.

What you’re actually buying

The INDX conversion kit is sold as a way to add toolchanging to a compatible CORE One platform, so each material can have its own dedicated path and nozzle. People buy it for multi-material parts, switching between nozzle sizes inside one job, and reducing purge waste compared with single-hotend color swapping workflows. It is not a complete printer, and it is not a filament-switching unit that feeds multiple filaments into one hotend.

Prusa frames the product as a conversion kit that reuses your existing printer ecosystem, including print sheets and software workflow, in the conversion kit listing. That framing matters for budgeting, because the “base” purchase is the kit, and the rest of the spend is driven by how you equip it, how you maintain it, and how often you use multi-material features.

INDX conversion kit vs other approaches

Toolchanging is one path to multi-material printing, but it is not the only one. Some systems swap hotends or nozzles, some push multiple filaments through a single melt zone, and some rely on purge towers and priming routines that trade money for waste and time. The INDX approach is built around multiple tools, which can reduce purge material, but it also pushes complexity into mechanical docking, tool alignment, and having multiple spools managed at once.

Market alternatives can be priced in the same neighborhood, but the comparison still depends on what you are buying. Tom’s Hardware describes a Bambu Lab H2C presale price starting at $2,399 and outlines its nozzle-swap approach in a Formnext roundup. That is a different bundle than a conversion kit, since it rolls hardware, enclosure, and multi-color workflow into one platform choice, rather than asking you to retrofit an existing machine.

4-tool and 8-tool versions

The four-tool kit is a narrower loadout, and the eight-tool kit is meant for the buyer who wants more materials or nozzle setups ready without swapping hardware between jobs. That difference changes the budget even before you look at shipping or tax handling, because it affects the number of toolheads you are managing, how many spools you keep in active rotation, and how much time you will spend dialing in profiles for different filaments and nozzles.

Tool alignment and calibration are where the conversion can demand extra time. On the eight-tool kit page, Prusa describes a toolhead offset calibration approach and says calibration takes 15 seconds per toolhead in the eight-tool kit notes. That is not a cash line item, but it is part of the “real” cost if the printer is used for work, because calibration time and troubleshooting time can replace print time. Tool count matters. Downtime matters.

What’s in the box

Both kit sizes are built around the same idea: a “smart” active head that does the work, plus passive tools that dock and get picked up as needed. What changes between the versions is the number of tools you can keep mounted and ready. That is why many buyers spend as much time on their “extras” list as on the checkout page. If you plan to run different nozzle sizes, abrasive filaments, or support materials, the spares and maintenance parts become part of the ownership plan rather than an occasional purchase.

The add-on costs are usually the things you buy to keep the system running smoothly rather than the parts that make it work on day one, and that’s where many budgets drift. A long print schedule can justify extra nozzles and wear parts, and multi-material printing tends to reward dry filament handling and spare PTFE parts, because a jam can waste hours. This is where readers often compare filament spend, since purge-heavy systems can chew through material. For background on filament economics, see 3D printer material cost.

Cost driver	Why it matters with INDX
Tool count	More tools means more spools managed at once and more maintenance points to keep consistent.
Spares and consumables	Nozzles and maintenance parts become a larger line item when the system is used heavily.
Filament handling	Dry storage and consistent feed paths reduce the risk of multi-spool jams and brittle support failures.
Downtime	Conversion and tuning can idle the printer, which matters if the machine is tied to paid jobs.

Taxes, tariffs, and checkout line

Prusa’s documentation says that for other non-EU countries, if an order is processed via Global-e, local taxes can be calculated during checkout, and in some cases fees are collected on delivery, in its VAT and customs guidance. That matters because two U.S. buyers can see different totals even with the same kit, based on where the package is going and how the payment flow is handled.

The same Prusa guidance also discusses tariffs and says that starting August 7, 2025, a 15% universal tariff applies for orders bound to the US, and it notes that charges are included in the price when paid through Global-e, in the tariff FAQ section. Shipping is still its own line item. Sales tax is still its own line item. The checkout total is the number that matters, and it can be different from the headline kit price even before you add any accessories.

Mini cases

Case 1 is an existing CORE One or CORE One+ owner ordering the four-tool kit and running it as a targeted upgrade for multi-material jobs. This buyer is aiming to spend on the conversion itself, then add spares only after the first few weeks of use reveal what wears fastest in their materials mix. Their risk is not buying the wrong platform, it is buying capability they do not schedule enough to justify the conversion time.

Case 2 is the buyer who wants the eight-tool setup from day one because their workflow includes frequent material changes, nozzle swaps, or complex models where purge waste is a real constraint. This buyer spends more up front but can reduce the routine of pulling spools and changing hardware between jobs. Case 3 is the small shop buyer who treats the kit as a production tool and buys backups and maintenance parts early so the printer does not go down mid-week. The line between “kit price” and “real total” is mostly driven by spares, storage, and the value of time, not by the kit SKU itself.

Worked total example

Using the launch figures that Fabbaloo lists, the four-nozzle kit at $749 and the eight-nozzle kit at $999 differ by $250 because $999 minus $749 equals $250, and that difference works out to $62.50 per extra tool because $250 divided by four extra tools equals $62.50, in the published price list.

Hidden costs

Returns and support policies matter more on a conversion kit than on a finished printer, because a buyer can discover compatibility issues only after opening the box and comparing parts to their machine. Prusa’s help article says goods can be returned within 60 days after delivery, and it also notes limits for opened consumables, in its refunds and returns article. A return can also mean repacking time and return shipping costs, which is why the “risk” line item is not just the kit price.

Warranty scope can also affect budgeting if you expect service-level coverage. Prusa says that for products purchased as a kit, the warranty covers individual components, but it does not include repair service or shipping costs for in-house technicians, and it notes factory repair can be charged, in its warranty policy. If your printer is used to fill orders, that difference can be the gap between a short parts swap and a longer interruption that forces you to reschedule work.

Who this cost makes sense for

INDX makes the most sense when you already own a compatible CORE One machine and your print queue regularly benefits from multiple materials, support filaments, or nozzle changes that you do not want to do by hand. It also fits the buyer who is comfortable treating a printer like a maintained system, with spare parts, calibration routines, and a workflow for storing multiple spools in good condition.

It is a harder sell when your work is mostly single-material parts or you need guaranteed uptime without conversion work. The kit can still be a fun capability upgrade, but the payback is tied to how often you will really use toolchanging features, not to the fact that the option exists.

Makes sense if

• You already run a CORE One or CORE One+ and want toolchanging without buying a second printer.
• You print multi-material parts where support materials, flexible inserts, or color changes are routine.
• You can afford printer downtime for conversion, tuning, and test prints.
• You keep spare nozzles and maintenance parts and treat the printer like a maintained machine.

Doesn’t make sense if

• Your workflow is mostly single filament and you rarely change nozzles.
• You need guaranteed uptime for paid jobs and can’t pause production to convert hardware.
• You planned to outsource multi-color prints instead of owning a complex setup, see cost to print at Staples.
• You only want occasional novelty color prints, where a simple single-material job like 3D printing a mask is the bulk of your usage.

Takeaways

• The first-batch kit prices being reported for April 2026 sit at $749 and $999.
• The gap between those two list prices is $250 using the published launch numbers.
• Checkout totals can shift with Global-e handling, shipping, and local taxes or duties.
• Spare parts, filament storage, and downtime can move the real budget more than the SKU name.
• The clearest fit is the existing CORE One owner who prints multi-material jobs regularly.

Answers to Common Questions

Does the kit price include shipping?

Prusa shows the kit as a hardware purchase, and shipping is added at checkout based on destination and order contents.

Do you need a CORE One or CORE One+ to use the kit?

Yes, it’s sold as a conversion kit for the CORE One family, so the kit has no practical use without a compatible base printer.

Is the eight-tool version always the smarter buy?

No. The higher version is easiest to justify when you will keep many materials or nozzle setups loaded and used often, rather than treating toolchanging as an occasional convenience.
