Anycubic SP Kobra S1/S1 Combo Hotbed Components

• The Anycubic SP Kobra S1 / S1 Combo Heated Bed Assembly (Hotbed): Is the primary thermal build surface platform engineered specifically for the enclosed CoreXY architecture of the Kobra S1 series.It consists of an aluminum alloy heat-spreader sub-plate, a high-power AC/DC heating trace element, a pre-applied flexible magnetic sticker base, integrated thermistor wiring, and bottom thermal insulation to ensure uniform bed temperatures during high-speed printing.
• High-Efficiency Uniform Thermal Heating: Designed with dense trace routing across the aluminum plate to heat rapidly up to 110°C without cold spots, preventing first-layer corner warping on engineering polymers (ABS/ASA/PET-CF).
• Pre-Applied High-Temp Magnetic Sheet: Factory-laminated with a flexible magnetic base rated for continuous high temperatures, securing spring-steel PEI build plates without shifting under rapid Z/Y motion.
• Integrated Bottom Thermal Shielding: Features a bottom thermal insulation cotton backing that redirects heat upward toward the build surface while protecting lower electronics from heat exposure inside the enclosed chamber.
• Heavily Reinforced Strain-Relief Harness: Includes a fixed rear wire relief bracket to prevent copper conductor flexing stress and thermal fatigue along the power and thermistor leads.
