100 × 100 mm, 24 V, 60 W adhesive flexible silicone heater for bonding beneath a compatible aluminium plate to build a compact heated bed. It is supplied wired and includes a 100K B3950 NTC thermistor with an XH2.54 connector.
Its nominal current is 2.5 A, making it suitable for small printers, test fixtures and custom 24 V projects when the available surface, output capacity and safeguards have been checked.

Mechanical and electrical compatibility
It suits a plate with a flat underside offering at least 100 × 100 mm of usable space, without screws, recesses or obstructions in the adhesive area. A printer's advertised build area does not always match the physical space beneath its bed; check the plate, fasteners, cable exit and moving path before purchase.
The 24 V power supply must cover the heater's 60 W load and every simultaneous machine load with adequate margin. A controller's bed output may only be used when its manufacturer confirms that its MOSFET, fuse, terminals and PCB traces can carry at least 2.5 A continuously with margin.
If the output capacity is unclear, an external stage such as the 30 A FYSETC MOSFET module for 12/24 V DC loads can be added. Its nominal rating does not replace correct wiring, fusing or thermal verification.
Installation
- Offer the heater up beneath the plate before removing the adhesive liner.
- Check for a cold resistance close to 9.6 Ω, allowing for meter and probe accuracy.
- Clean, degrease and dry a flat aluminium plate.
- Bond progressively from one edge without bubbles, folds or stress.
- Never cut, drill, crease or attempt to reposition the heater after bonding.
- Add strain relief so bed motion is not transferred to the electrical joints.
Thermistor configuration
The sensor is a generic 100K B3950 NTC. After configuration, compare its cold reading with ambient temperature and verify heating with an independent instrument.
Marlin
With the common 4.7 kΩ pull-up, the initial option for this curve is:
#define TEMP_SENSOR_BED 11Keep THERMAL_PROTECTION_BED enabled. If bed PID is enabled and the power stage supports this switching method, tune it at the intended working temperature; for example, M303 E-1 C8 S60 runs eight cycles at 60°C.
Klipper
Use sensor_type: Generic 3950 inside [heater_bed]. The correct sensor_pin and heater_pin depend on the board. Once the assembly has been verified, run PID_CALIBRATE HEATER=heater_bed TARGET=60 followed by SAVE_CONFIG.
RepRapFirmware
The curve can be defined through M308 using T100000 B3950; for example, M308 S0 P"bed_temp" Y"thermistor" T100000 B3950 A"Bed". Replace the sensor number and port with those required by your controller.
Protection and commissioning
- Dedicated fuse on the heater supply branch.
- Wires, terminals and connectors suitable for the current.
- Non-resettable thermal fuse in contact with the plate and able to interrupt the heater.
- Firmware thermal-runaway protection enabled and tested.
- Supervised staged commissioning while checking connections, switching stage and sensor reading.
Firmware protection does not replace an independent thermal cut-off. The safe temperature depends on the complete assembly: plate, adhesive, insulation, sensor, wiring and build surface.
This is for you if
- You are building a compact bed with a 24 V supply.
- You have a flat 100 × 100 mm underside available.
- You need an adhesive heater with an integrated B3950 thermistor.
This is not for you if
- Your controller, PSU or wiring cannot support the complete load.
- The usable area is smaller or contains obstructions.
- You need a complete bed: the aluminium plate and build surface are not included.
