What is a 100K Thermistor used for? ▼
A 100K Thermistor is primarily used for measuring high temperatures in 3D printers (hotends and heatbeds). It is also widely used in household appliances like coffee makers and ovens.
How do I configure this in Marlin Firmware? ▼
In your Marlin Configuration.h file, you should typically set your thermistor type to '1' or '11' depending on the specific table, which corresponds to the 100k NTC 3950.
Is the 100K thermistor different from a 10K thermistor? ▼
Yes. A 100K thermistor has 10 times the resistance (100,000 ohms) at 25°C compared to a 10K version. They are not interchangeable in circuits unless the pull-up resistor and software code are changed.

Why the 100K Thermistor is Essential for 3D Printing

When it comes to 3D printing, temperature precision is the difference between a successful print and a nozzle clog. The 100K thermistor is the most common sensor used in FDM printers because of its ability to handle high temperatures up to 250°C.

The NTC 100K 3950 model is specifically calibrated to work with 3D printer controller boards like SKR, RAMPS, and Creality original boards. Because it is an NTC (Negative Temperature Coefficient) sensor, its resistance drops as the hotend heats up, allowing your printer to maintain a steady melting point for PLA, ABS, and PETG filaments.
