Adapt or expand your rapid-swap 3D printing setup with the premium standalone E3D Revo Cold Side Heatsink. In the E3D RapidChange Revo-lution ecosystem, a complete hotend assembly is built by pairing a cold-side heatsink with a matching hot-side (the heatercore and nozzle kit). This product delivers the dedicated cold-side housing alone—offering the perfect solution if you are migrating your existing setup to a new 3D printer, replacing a worn carriage component, or building custom toolheads.
By selecting the specific cold-side geometry optimized for your hardware, you retain your existing Revo heater and nozzles while cleanly matching your machine's mounting requirements.
The Benefits of the RapidChange Revo Ecosystem
Transitioning your toolhead to the Revo platform upgrades your entire printing experience with modern, user-focused thermal and mechanical design:
Ready for Revo: Swap nozzles cold in less than a minute using only your fingers. No heavy tools, no stripped aluminum heater block threads, and absolutely zero risk of hazardous hot tightening.
Leak-Proof Factory Seal: Because Revo nozzles combine the nozzle tip and the heatbreak into a single preassembled unit, there are no internal threaded joints where molten filament can leak out to ruin prints.
PTC Runaway Safety: Designed to pair with the Revo HeaterCore. This heating element utilizes a Positive Temperature Coefficient (PTC) material matrix that automatically limits max temperature, drastically reducing hazards in the event of thermal runaway.
Tailor-Made Heatsink Varieties
Configure your printer's toolhead layout by choosing the precise physical mounting interface you need:
Revo Voron: Features a rigid, compact mount tailored specifically for the Voron Stealthburner, Afterburner, and other popular coreXY toolheads.
Revo Six: Designed with a classic groove-mount profile to act as a direct drop-in replacement for standard E3D V6 heatsinks.
Revo Prusa: Drop-in ready for classic Prusa setups (like the MK3S+ and MINI+) with matching electrical and mechanical standards.
Revo Creality: Tailored to fit seamlessly on popular beds like the Ender 3, Ender 5, and CR-10 series.
Revo Hemera & LGX Micro: Specifically engineered to bolt directly onto elite direct-drive extruders for ultra-short filament paths.
Revo Roto: Integrates perfectly with ultra-lightweight direct-drive assemblies.
Important Operating Considerations
Hot-Side Required: This is a standalone cold-side heatsink. To make a functional hotend, you must pair it with an E3D Revo HeaterCore and a Revo nozzle.
Z-Offset Calibration: While Revo nozzles are machined to incredibly tight manufacturing tolerances, always check and slightly adjust your printer's Z-offset after changing or replacing your hardware configuration.
