Description

Silicone heating pad heater 300 mm x 300mm for 3d printer heat bed 24 V 350W

Silicone Heater Pad – 24V 428W | Size: 350mm x 350mm | High-Power Heated Bed for 3D Printer Build Platforms

Description:
Achieve faster and more consistent heating across your 3D printer’s build surface with this high-performance 350×350mm Silicone Heater Pad. Powered by 24V at 428W, this pad ensures rapid heat-up times and even temperature distribution, significantly reducing warping and improving first-layer adhesion.

Perfect for large-format 3D printers, DIY builds, or upgrading your existing heated bed to handle high-temperature filament printing such as ABS, PETG, Nylon, and more.

Product Features:

• Powerful Performance: 24V / 428W output for quick and even heat-up

• Large Size: 350mm × 350mm — ideal for big-format print beds

• Uniform Heating: Reduces warping and improves adhesion across the full build plate

• Flexible Silicone Construction: Adapts smoothly to aluminum beds, glass, or magnetic plates

• Easy Installation: Includes pre-attached power leads and adhesive backing (optional in some models)

• Thermistor Support: Designed with a central spot for sensor placement
