E3D Revo Voron Hotend

Overview#

The E3D Revo Voron is a revolutionary hotend developed in collaboration with the Voron Design team specifically for the Voron StealthBurner toolhead. It combines E3D’s innovative RapidChange nozzle system with a compact, lightweight design optimized for high-performance CoreXY printers. The Revo Voron represents a significant advancement in hotend technology, allowing for tool-free nozzle changes at room temperature and improved thermal performance.

Key Features#

RapidChange Nozzle System#

• Tool-Free Nozzle Changes: Swap nozzles at room temperature using just your fingers - no tools or hot tightening required
• Integrated Nozzle and Heatbreak: Factory-sealed combination eliminates the risk of leakage and improves thermal performance
• Variety of Nozzle Options: Available in various sizes (0.15mm to 0.8mm) and materials (brass, ObXidian, high-temperature)

HeaterCore Technology#

• Integrated Heater Design: Thermistor, heater, and heater block combined into a single unit for superior thermal efficiency
• Fast Heat-Up Times: Reaches printing temperature in seconds rather than minutes
• Positive Temperature Coefficient: Power reduces as temperature increases, reducing hazards in thermal runaway situations

Voron-Specific Design#

• Rigid 4-Point Mounting: Uses four M3 x 0.5 bolts to secure firmly to the Voron StealthBurner
• Ultra-Lightweight Construction: Only 25g total weight for improved speed performance and reduced ringing
• Anodized Aluminum Heatsink: Available in red, blue, or grey to complement Voron color schemes

Open Source Design#

• GPL V3 Licensed: The heatsink design is open source, allowing for community modifications and improvements
• Compatible with Voron Ecosystem: Designed specifically for Voron printers and fully integrated with their ecosystem

Specifications#

Nozzle Ecosystem#

The Revo Voron uses E3D’s RapidChange Revo nozzle system, which includes multiple options:

Standard Flow Brass Nozzles#

• Available in 0.15mm, 0.25mm, 0.4mm, 0.6mm, and 0.8mm diameters
• Suitable for standard materials like PLA, PETG, TPU, and ABS
• Max temperature: 300°C

High Flow Brass Nozzles#

• Available in 0.4mm, 0.6mm, and 0.8mm diameters
• Increases flow rates by approximately 70% compared to standard nozzles
• Perfect for speed printing applications

ObXidian Nozzles#

• Hard-wearing nozzles with E3DLC™ coating
• Resistant to abrasive filaments
• Non-stick properties ideal for sticky materials like PETG
• Available in standard and high flow variants

High-Temperature HTX Nozzles#

• Chromium Nitride coating for abrasion resistance
• Can operate at temperatures up to 500°C
• Ideal for engineering materials like Nylon, Polycarbonate, and PEEK

Heatercore Options#

Standard 40W Heatercore#

• Suitable for most printing applications
• Available in 12V and 24V versions
• Includes standard thermistor (max 300°C)

High-Performance 60W Heatercore#

• Recommended for high flow applications, extreme part cooling, or high-temperature printing
• Faster heat-up and more consistent temperatures under high demand
• Available in 12V and 24V versions

High-Temperature Heatercores#

• Available with PT100 or PT1000 temperature sensors
• Capable of reliable temperatures up to 450°C
• Ideal for engineering materials

Installation Guide#

1. Prepare the StealthBurner:

   • Ensure you have the correct StealthBurner printed parts for Revo Voron compatibility
   • Remove any existing hotend from your toolhead

2. Mounting the Heatsink:

   • Secure the heatsink to the toolhead using four M3 x 0.5 screws
   • Ensure the heatsink is oriented correctly according to Voron documentation

3. Installing the HeaterCore:

   • Insert the HeaterCore spring into the groove at the bottom of the heatsink
   • Push the HeaterCore into place until it locks securely
   • Connect the heater and thermistor wires to your control board

4. Installing a Nozzle:

   • Screw in your chosen Revo nozzle by hand until it’s finger-tight
   • No heat tightening required

5. Configuration:

   • Update your firmware settings to match the HeaterCore specifications
   • Perform PID tuning to optimize temperature control

Maintenance#

1. Nozzle Changes: Simply unscrew the existing nozzle at room temperature and screw in a new one
2. HeaterCore Replacement: If needed, the HeaterCore can be easily removed and replaced
3. Cleaning: Standard nozzle cleaning techniques work well with Revo nozzles

Benefits Over Traditional Hotends#

1. Convenience: Tool-free nozzle changes make switching between different sizes effortless
2. Speed: Fast heat-up times reduce waiting between prints
3. Performance: Improved thermal efficiency and consistent extrusion
4. Reliability: Sealed nozzle-heatbreak units eliminate a common failure point
5. Weight Reduction: Ultra-lightweight design improves print quality
6. Safety: PTC design reduces thermal runaway risks
