Optimized Heat Management
Prevent external cooling of the hot block with our Convection Shield, ensuring precise temperature control during high-speed printing. Crafted from precision-machined high-temperature aluminum, it outperforms traditional silicone insulators in durability, eliminating the risk of drooping, falling off, or degrading over time. The thin air gap and ceramic washers minimize heat transfer, maintaining a stable and controlled printing environment.
Seamless Integration
The Convection Shield fits Mosquito Magnum+® and Prime™ Hotends with the integrated captive screw assembly, enhancing their performance with efficient part cooling and precise filament temperature control during high-speed printing. It is also compatible with RepRap-style nozzles featuring a 6 mm hex and lower, allowing easy integration into your existing setup for versatile printing capabilities.
Note: To change nozzles, the Convection Shield must be removed first.
Free shipping over $100 is available for US customers only. See terms for full details.
