The Elegoo Neptune 4 Series — including the Neptune 4 Pro, Neptune 4 Plus, and Neptune 4 Max — represents one of the best-engineered families of FDM 3D printers on the market. Each model features precise motion systems, strong axis supports, and fast accelerations that allow high-speed, high-quality printing right out of the box. However, one capability is still missing: multi-color 3D printing.
Can the Elegoo Neptune 4 series print in multiple colors?
The answer is yes.
Why You Need Multi-Color Printing for the Neptune 4 Series
Elegoo’s Neptune 4 printers offer excellent mechanics and Klipper firmware pre-installed, but they don’t include any official multi-filament or multi-color upgrade module. Users looking to print in multiple colors often have to stop their print mid-way to change filament manually — a time-consuming process that reduces precision and consistency.
To truly unleash the full creative potential of these machines, the perfect pairing is Co Print’s KCM Set — the only multi-color printing solution fully compatible with the Elegoo Neptune 4 series.
The Perfect Upgrade: Co Print KCM Set
The KCM Set is a professional-grade multi-color upgrade kit designed specifically for Klipper-based printers like the Neptune 4 Pro, Plus, and Max. It replaces manual filament swaps with automated color changes using precision control and synchronized motion.
- 🎨 Available in 4-color ($289) and 8-color ($389) versions
- ⚙️ Full integration with Klipper firmware and Moonraker
- 🧩 Supports 3D-printed mounts for all Neptune 4 variants
- 📏 Keeps almost the full print area — no significant build-plate loss
- 🚀 Optimized axis mechanics allow exceptional surface finish even at high speed
Why the Neptune 4 + KCM Set Combo Is Outstanding
What makes this combination so effective is how well the Neptune 4’s mechanics complement Co Print’s technology:
- Stable Z-axis and linear rails ensure perfect layer alignment even during color changes.
- High-acceleration Klipper control keeps print times low while maintaining quality.
- Rigid frame and dual lead screws eliminate wobble and vibration for cleaner transitions between colors.
- Co Print’s ChromaHead delivers clean filament purging, resulting in vivid, artifact-free prints.
Together, the KCM Set and Neptune 4 Series create one of the fastest and most precise multi-color 3D printing systems available today.
Compatibility Across the Entire Neptune 4 Series
The KCM Set is fully compatible with every printer in the series:
- ✅ Neptune 4 – direct integration, with printed adapter mount
- ✅ Neptune 4 Pro – direct integration, with printed adapter mount
- ✅ Neptune 4 Plus – larger frame, identical electronics, same mounting points
- ✅ Neptune 4 Max – extra build volume, printed mount keeps almost full bed usage
Co Print provides 3D-printable adapter files for all three models, ensuring easy installation without losing build space. That means your multi-color printing potential scales directly with your printer size — from Pro to Max.
Setup Overview
- Install the KCM unit and connect it via USB to the printer’s control board.
- Mount the ChromaHead using the dedicated 3D-printed bracket for your Neptune model.
- Connect up to 8 CX-I extruders to the KCM module.
- Update your
printer.cfgfile and restart Klipper. - Slice your model with color assignments and start printing!
