Adding Dual Extrusion to Your 3D Printer: A Cost-Effective Guide

Dual extrusion 3D printing opens up a world of possibilities, allowing for intricate color gradients and complex prints. In this blog post, we will explore a simple and affordable method of adding dual extrusion capabilities to your existing 3D printer. We will delve into the different types of dual extrusion systems available, compare their features, and guide you through the installation process. By the end of this post, you will have the knowledge and tools to elevate your 3D printing projects with dual extrusion.

Evaluating Dual Extrusion Systems

When considering dual extrusion systems, two main options stand out: a two-in-one-out hot end and a mixing hot end. The former allows for printing with two different materials simultaneously but requires a purge block between color changes. On the other hand, a mixing hot end enables seamless color transitions and gradients without the need for a purge block. While slightly more expensive, the mixing hot end offers enhanced versatility and is capable of producing stunning results.

Product Comparison:

Two-in-One-Out Hot End:
- Compatible with Ender 3, Ender 5, and CR-10.
- Price: $19.
- Requires a purge block, leading to filament waste.
Mixing Hot End:
- Filaments are mixed in the heater block.
- Price: $27.
- Allows for color gradients without a purge block.

Installing Dual Extrusion System

Parts Needed:

Second filament spool holder.
Spare stepper motor.
Cabling back to the main board.
Extruder assembly matching the original extruder.
Bracket for mounting the extruder.
Extra stepper motor driver.

Installation Process:

Mounting the new hot end may require a custom adapter due to spacing differences.
Ensure proper cable management and routing for all components.
Update the firmware to accommodate the new extruder.
Perform a PID auto-tune for optimal temperature control.
Recalibrate bed leveling or Z-offset if necessary.

Leveraging Dual Extrusion Capabilities

With the dual extrusion system in place, you can now explore various printing techniques, such as traditional dual extrusion and color gradients. The firmware settings allow you to control the filament mixing ratio and seamlessly transition between colors during a print.

Virtual Tools Feature:

Create virtual tools to mix colors and achieve multi-color prints with just two rolls of filament.
Store custom color profiles for easy access during printing.

Summary

Adding dual extrusion capabilities to your 3D printer opens up a new dimension of creativity and flexibility in your printing projects. While there are advantages and challenges to both two-in-one-out and mixing hot end systems, the ability to produce intricate color gradients and multi-color prints is a game-changer. Experiment with different settings and techniques to unleash the full potential of dual extrusion printing.
