Upgrade your 3D printer's thermal performance with the West3D Universal 120V Silicone Edge-to-Edge AC Bed Heater. Exclusively engineered by West3D to provide edge-to-edge heating coverage on Voron-style and custom build plates, this high-wattage AC silicone heater delivers rapid, uniform heating across the entire build surface.
Built with premium Lohmann high-temperature adhesive, the pad stays securely bonded to your build plate over long-term high-temperature printing cycles while minimizing off-gassing and odor. Designed with safety in mind, each heater features integrated backup thermal protection via an embedded self-resetting thermal switch (CF79F-150A, rated for 150°C).
For added reliability, both the main power leads and thermistor wires are elevated from the bottom of the silicone pad to provide clean clearance over bed mounting hardware and obstacles. The integrated NTC 100K thermistor provides precise temperature monitoring and is fully compatible with Klipper firmware (configured as Generic 3950).
Key Features & Specifications
Voltage: 120V AC (intended for US electrical standards)
Wiring: Extended length leads; elevated wiring relief for easy routing
Wire Identification: White wires = AC power supply; Red wires = Thermistor sensor
Sizing Note: Heaters are sized within 1 mm of nominal build plate dimensions. Designed to fit standard Voron aluminum build plates (which are typically 5 mm larger than stated printable area). Ensure your physical bed surface matches or exceeds heater dimensions prior to installation.
Printer Compatibility
Voron 3D printers and custom Voron-style builds
Printers for Ants series (PFA, Micron, Salad Fork with corresponding bed dimensions)
Any 3D printer with an appropriately sized aluminum build plate and 120V AC SSR power supply setup
Installation & Safety Guidelines
Safety First: High-wattage AC heaters reach elevated temperatures rapidly. Never leave your printer unattended while in operation. The embedded thermal switch acts strictly as a secondary backup; always use a properly rated primary thermal fuse.
Surface Preparation & Application: Ensure the underside of your build plate is thoroughly cleaned, degreased, and scuffed before application. Refer to Keenovo's Bed Heater Installation Guide for best practices on sandwiching and mounting.
SSR Wiring: Connect the AC heating element (white wires) through a Solid State Relay (SSR) rated for your line voltage and current. Refer to Keenovo's SSR Wiring Guide for detailed wiring diagrams.
