Thermocouple A thermocouple is a temperature sensor used in 3D printers to accurately measure hotend and heated bed temperatures. It provides rapid response, wide temperature range, and high precision. Thermocouples are essential for high-temperature materials like PEEK, PEI, and metal filaments. They are more reliable and accurate than thermistors at extreme temperatures. Proper installation and calibration ensure consistent extrusion, layer bonding, and dimensional accuracy. Thermocouples enhance thermal stability, safety, and print quality, supporting advanced materials and industrial applications. |
