Beschreibung
A thermistor is a type of temperature sensor commonly used in 3D printers to measure the temperature of the printer's hotend and heated bed. The thermistor's resistance changes with temperature, allowing the printer to accurately control the temperature of the printing environment.
When selecting a thermistor for a 3D printer, there are a few key factors to consider:
-
Type: There are different types of thermistors, such as NTC and PTC, which have different temperature-resistance curves and may be more suitable for certain applications.
-
Resistance value: The thermistor's resistance value should match the printer's control board and firmware settings to ensure accurate temperature readings.
-
Temperature range: The thermistor should be able to accurately measure the temperature range required for the printer's hotend and heated bed.
-
Size and shape: The thermistor should fit within the printer's design and be compatible with the hotend and heated bed.
Some commonly used thermistors in 3D printers are the EPCOS B57560G104F and Semitec 104GT-2, which are both NTC thermistors with a 100K Ohm resistance at room temperature. These thermistors are widely available and provide accurate temperature readings for most 3D printing applications. However, depending on the specific printer design and requirements, other thermistors may be more suitable.
