The Idea
Every 3D printing enthusiast knows the problem: leftover filament spools that are too valuable to throw away, but not always the right color for the next project. What if you could combine the filament you already own to create new, custom colors? Meet NAUMX3 — a DIY filament color mixing system designed to combine up to three input filaments into a new filament with a custom color. Choose your input filaments, set your mixing ratios, and experiment with new color combinations. Your filament. Your ratios. Your colors.
NAUMX3 is designed for use with compatible FDM 3D printers and targets standard 1.75 mm filament.
Designed by Engineers. Supported by Experts.
Compatible with any standard FDM 3D printer.
Designed to work seamlessly with your existing 3D printing setup.
Upgrade your colors, not your printer.
More colors, zero new hardware.
Built for makers — works with the tools you already have.
No upgrades. No limits. Just more color.
NAUM X3 Mixing Chamber
Developed and refined through 3 years of intensive testing and engineering, the NAUM X3 Mixing Chamber is the heart of the multi-color filament system. Its innovative internal mixing geometry is designed to efficiently combine and homogenize up to three filament inputs, creating consistent and controlled color blending.
The compact design was developed through numerous prototypes and real-world tests, focusing on mixing performance, material flow, temperature stability, and reliability. The result is a unique solution specifically engineered for the NAUM X3 system.
3 Years of Development. One Innovative Mixing Solution.
FROM PROTOTYPE TO PRODUCT
Great products don’t happen overnight.
Behind our final design are countless prototypes, tests, modifications and improvements.
Every version helped us learn what worked — and what didn’t.
We redesigned, tested, printed and refined the concept again and again until we reached the product we were truly proud of.
This is what the journey to our final product looked like.
Hundreds of ideas. Countless iterations. One final product.
Why NAUMX3?
Save money: use what you already own.
Reduce waste: no more half-used spools.
Create your own colors: print exactly the shade you imagine.
Print smart: make only as much filament as you need.
With NAUMX3, the power of color mixing is in your hands.
Because true makers don’t just print — they create.
How It Works
NAUMX3 is a true DIY project — created by makers, for makers.
We’ve developed the complete concept and design, and everyone who supports the project will receive the 3D printable models to build their own NAUMX3 mixer at home.
Assembling the hardware is simple and straightforward.
We’ll provide detailed step-by-step instructions, along with video tutorials to guide you through every part of the setup — from printing the components to mounting the electronics.
This project is not just about getting a product.
It’s about joining a creative community of makers who build, experiment, and share.
NAUMX3 can mix up to three different filaments to create your own custom color.
The process is simple and intuitive — designed for every maker, from beginner to expert.
NAUMX3 is designed to be fully compatible with virtually any FDM 3D printer available on the market.
The device produces standard filament (e.g. 1.75 mm), which means it can be used with any printer that supports common materials such as PLA, PETG.
There is no need for special hardware modifications or proprietary systems.
Simply feed the custom filament created with NAUMX3 into your existing printer — just like any regular spool.
- Works with most desktop 3D printers
- No need to buy a new printer or upgrade your setup
- Compatible with standard materials and extrusion systems
- Easy integration into your current workflow
This makes NAUMX3 an accessible tool for every maker, regardless of their printer model or experience level.
1. INPUT MODULE X3-2.0
The Input Module securely holds up to three filament spools and feeds them smoothly into the system. Each filament is guided independently, ensuring consistent tension and reliable material delivery throughout the mixing process.
Purpose
- Holds the input filament spools
- Provides smooth filament feeding
- Prevents tangling and inconsistent tension
- Supports multiple filament colors and materials
2. NAUMX3™ Titan 2.0
The NAUMX3 is the intelligent control center of the entire system. It precisely regulates the feeding ratio of each filament, controls temperature, manages the mixing process, and coordinates every module to produce a single custom-colored filament.
Purpose
- Controls filament mixing ratios
- Manages extrusion temperature
- Synchronizes all system modules
- Creates a single custom filament from up to three input filaments
3. Puller MODULE PullForce™ 2.1
After extrusion, the filament passes through the pulling system. This module maintains a constant pulling speed, ensuring stable extrusion and helping achieve a uniform filament diameter.
Purpose
- Pulls the filament at a controlled speed
- Stabilizes the extrusion process
- Prevents stretching or compression
- Improves dimensional consistency
4. MESURE MODULE FilamnetEye™ 2.0
The Diameter Measurement System continuously measures the filament diameter in real time. The measured value is used to fine-tune the pulling speed, ensuring that the final filament remains within specification.
Purpose
- Measures filament diameter continuously
- Provides real-time quality control
- Automatically compensates for diameter variations
- Ensures consistent 1.75 mm filament
5. Spooler MODULE Glory™ 1.0
The final module automatically winds the finished filament onto a spool while maintaining constant tension. This produces neat, evenly wound spools that are immediately ready for storage or 3D printing.
Purpose
- Winds the finished filament automatically
- Maintains constant winding tension
- Produces clean, professional spools
- Keeps the filament ready for immediate use
More Than a 3D Printing Project – A Learning Experience
NAUM X3 is not just a machine—it’s an educational platform that inspires curiosity, creativity, and hands-on learning.
By assembling the system, users of all ages gain practical experience with mechanics, electronics, programming, and 3D printing technology. It encourages problem-solving, critical thinking, and engineering skills in a fun and engaging way.
Children can safely participate alongside parents, making it an excellent family STEM project that transforms learning into an exciting shared experience. Building something together not only teaches valuable technical skills but also creates lasting memories.
Learn. Build. Create. Together.
