Prusa INDX & 400°C HT Hotend: Multi-Material & PEKK-CF 3D Printing

Prusa Formnext 2025: Game-Changing Tech for the CORE One Lineup

Prusa Research has unveiled the Prusa INDX tool changer system and a 400°C HT hotend at Formnext 2025—two transformative upgrades that bring true multi-material 3D printing and high-temperature PEEK-class printing to the CORE One platform. These releases target industrial and professional users who’ve been locked out of advanced polymer workflows by cost, complexity, or proprietary material restrictions.

The INDX multi-material system removes the compromises of single-nozzle switching, enabling incompatible material combinations with near-zero waste. The 400°C HT hotend unlocks engineering polymers once reserved for industrial systems—PEKK-CF, PPS-CF, PPSU, and other high-performance thermoplastics needing extreme temperatures and tight thermal control.

The focus is clear: make professional-grade additive manufacturing accessible without sacrificing performance. Prusa is tackling the friction points—tool-changing capability, open-source material databases, and industrial-temperature hotends—while keeping the open-source philosophy and workshop reliability the brand is known for.

INDX: Scalable Multi-Material Printing from Bondtech Partnership

INDX is a new tool-changing system for the entire CORE One lineup, developed with Bondtech. A single active Smart Head (induction heating, sensing, Dynamic eXtruder drive) pairs with multiple passive tools—wireless, simple, and scalable (4/6/8 filaments) with no buffers, rewinding, waste chute, or complex mechanics.

For small-batch production and prototyping, INDX delivers full toolchanger speed with near-zero purge waste—making scalable multi-material work far more accessible.

Q: Is the INDX tool changer compatible with existing machines?

A: Yes. It’s designed to retrofit CORE One and CORE One+, giving current owners an economical upgrade path.Close-up of the passive, lightweight tool head from the INDX system, highlighting the mechanically simple design.

Industry Standard: The OpenPrintTag Material Database

The OpenPrintTag Material Database is an open, searchable library of materials, colours, and properties from any manufacturer. OpenPrintTag is a rewritable NFC standard for smart spools, so printers auto-read material type, colour, and parameters.

Slicers/firmware can pull certified filament data instantly. Dozens of manufacturers are adopting the OpenPrintTag standard, and the Prusa app supports reading/writing tags (including QR-to-NFC for refills).

Q: What’s the main benefit of OpenPrintTag?

A: An open data standard for universal material identification—no more manual profile entry or inconsistent data.

HT Hotend: Unlocking High-Performance Polymers

The 400°C HT Hotend Upgrade is a quick-swap for CORE One, CORE One+, and CORE One L—installable in under a minute. With 400°C nozzle temps, it reliably prints PEKK-CF, PPSU, PPA-CF, and PPS-CF, meeting AS9100 and ISO 10993 requirements.

It also boosts current technical filaments—up to 30% sturdier parts from PA11-CF and PC-CF via higher melt temps and stronger layer adhesion. Availability: February 2026.

Q: What’s the max temperature?

A: 400°C, enabling PEEK/PPSU-class polymers.

Q: Does it improve existing filaments?

A: Yes—up to 30% stronger parts from carbon-filled nylons and PC-CF.

Refined Hardware: CORE One+ and USS Drybox

CORE One+ adds an automated top vent and redesigned filament insertion for easier flexibles; unfulfilled orders will be upgraded automatically.

The USS Drybox (hydrophobic polypropylene) is stackable with a sealable filament slot, letting you print directly from storage—ideal for moisture-sensitive materials.

Q: Does Prusa offer a dedicated solution for drying/preventing moisture?

A: Yes. The USS Drybox stores and feeds moisture-sensitive filament (e.g., Nylon, PETG) without exposing it to humid air.
