Prusa Research launches 400°C HT Hotend for CORE One series

Key Takeaway

The new HT Hotend enables 400°C printing on Prusa CORE One+/L+ machines to support industrial-grade polymers.

Summary

Prusa Research has released the HT Hotend, a quick-swap upgrade for the CORE One+ and CORE One L+ printers. This hardware allows for temperatures up to 400°C, enabling the use of high-performance polymers like PPS-CF, PPS-GF, and PPA-CF Core. To support this ecosystem, Prusa is also introducing new HighTemp build sheets and specialized filaments.

Technical capabilities of the HT Hotend

  • Enables printing temperatures up to 400°C.
  • Improves interlayer adhesion for existing Prusaments: PA11 Carbon Fiber (+23%), ASA (+18%), PC Blend (+7%), and PC Blend Carbon Fiber (+7%).
  • Supports high-performance polymers including PPS-CF, PPS-GF, and PPA-CF Core.
  • Compatible with CORE One+/L+; not compatible with INDX.
  • Requires HighTemp sheets for optimal adhesion with materials like PEI, PEEK, and PPS.
  • Advanced materials like PEEK or PEKK may be limited by the printer's 60°C chamber temperature.

Why it matters

The upgrade provides a more affordable path to industrial-grade 3D printing by bringing high-temperature capabilities to desktop-class machines.
