High-Temp Copper Heater Block for Precise 3D Printing

About this item

POLISI3D's high-temperature copper alloy heater block measures 23x16x11.5mm, engineered for demanding 3D printing environments. Its copper composition offers over three times the thermal conductivity of brass, ensuring precise temperature control and faster heat-up times. The alloy is hardened and treated to resist oxidation at temperatures exceeding 500°C, making it ideal for high-temperature hotends like V6 and Titan Aero. The nickel-based plating enhances durability and corrosion resistance, supporting consistent performance over long print sessions.

Designed for OD 3mm cartridge sensors, this machined copper heater block guarantees tight thermal regulation, reducing temperature fluctuations during high-temp printing. Its robust construction and high resilience make it suitable for advanced additive manufacturing tasks, especially in Indian climate conditions where heat stability is critical. The package includes one piece, factory-sealed, with all duties paid for quick import clearance and delivery in 11-13 days.

Whether upgrading your Prusa i3 MK3 or Titan Aero, this copper heater block provides reliable, high-temp performance. Compatible with standard 3mm cartridge sensors, it supports precise temperature management essential for quality 3D prints in India’s varied environments.

Key Features

  • Size: 23x16x11.5mm. Material: Copper; It is machined with very high precision and high quality
  • Copper has more than 3x the thermal conductivity of brass, and the copper alloy we use has been hardened and treated to reduce the oxidation that occurs in copper at high temperatures. The higher thermal conductivity will also slightly increase your heat-up times, and can provide tighter temperature control.
  • This heater block is for OD 3mm cartridge temperature sensor
  • This copper-alloy is very temperature resilient, and will not start to soften or anneal until way beyond 500°C, making it perfect for the high-temperature printing. In addition to high temperature performance this Block have an advanced nickel based plating
  • Package: 1piece

Why choose this product

Advanced Copper Alloy for High-Temp Printing

POLISI3D's heater block uses a hardened copper alloy with nickel plating, supporting temperatures well beyond 500°C. This alloy resists oxidation and softening, ensuring consistent high-temperature performance for demanding materials like PEEK and PEI. Its superior thermal conductivity provides tighter temperature control, reducing print defects and improving quality in Indian climate conditions where heat stability is vital.

Ideal for Professional and Hobbyist 3D Printing

Designed for hotends like V6, Titan Aero, and Prusa i3 MK3, this copper heater block offers reliable, high-temp operation. Skip if using low-temperature filaments or budget setups. Suitable for high-precision, high-temperature applications in India, supporting advanced manufacturing and prototyping needs.

How to use

  • Insert the heater cartridge — Carefully insert the heater cartridge into the copper block, ensuring proper alignment and contact for optimal heat transfer.
  • Connect the sensor — Attach the OD 3mm cartridge sensor to the designated port, securing it firmly for accurate temperature readings.
  • Secure and test — Fasten the heater block onto your hotend assembly, power on, and verify temperature stability before printing high-temp materials.
