Our Advanced 8-Step Extrusion Process
From raw material to spooled filament, every stage is engineered for precision, consistency, and reliability.
1. Extruder
The core of the production line. Our precision screw and multi-zone heating system melts and plasticizes raw materials into a homogenous molten stream, extruded through a hardened steel nozzle.
2. Circulating Cooling Water Tank
The hot filament is immediately immersed in a circulating cold water bath, rapidly solidifying it to ensure a perfectly round cross-section and stable structure.
3. Laser Diameter Gauge (Optional)
A high-precision, dual-axis laser micrometer provides real-time, non-contact diameter measurement, feeding data to the haul-off system to guarantee a tolerance of ±0.03mm.
4. Haul-off Wheel
A digitally controlled, high-traction wheel pulls the filament at an exceptionally stable speed. This works in tandem with the extruder and laser gauge to control the final filament diameter with utmost precision.
5. Dancer Wheel
This tensioning system acts as a buffer, maintaining consistent tension between the puller and the winder. It prevents stretching and ensures accurate length counting and neat spooling.
6. Meter Counter
An integrated digital counter accurately measures the length of the produced filament, allowing for precise spooling according to your specified length.
7. Automatic Traverse Device
The automated traversing guide moves from side to side, laying the filament perfectly on the spool. This ensures a neat, tangle-free wind every time.
8. Winder
The final stage. The winder automatically spools the finished, high-quality filament onto a standard reel, ready for immediate use, storage, or packaging.

Frequently Asked Questions
Is it cheaper to make your own 3D filament?
Absolutely. Raw plastic pellets cost significantly less than commercial filament spools—often up to 80% cheaper. For any organization that prints regularly, the cost savings on materials alone provides a rapid return on investment.
What plastics can I use in a filament extruder?
Our extruders are designed to work with a wide range of common thermoplastics, including PLA, PETG, and ABS. Furthermore, they are excellent for processing clean, shredded plastic waste from failed prints, turning your scrap into valuable material.
How do you ensure the filament has a consistent diameter?
This is achieved through a closed-loop control system. The optional Laser Diameter Gauge constantly measures the filament, and this data is fed to the Haul-off Wheel, which automatically adjusts its speed. This system is the key to producing professional-grade filament with tight tolerances (e.g., ±0.03mm).
Can I create custom-colored or composite filaments?
Yes. This is one of the main advantages. You can easily mix colorant masterbatch with virgin pellets to create custom colors. You can also experiment by adding other materials, like carbon fiber or wood dust, to develop unique composite filaments for specific applications.
Is a desktop filament extruder worth it for a small business or lab?
For small businesses, R&D labs, and educational institutions, a desktop extruder is a strategic investment. It drastically cuts material costs, enables rapid prototyping with custom materials, provides supply chain independence, and serves as a powerful tool for recycling and sustainability initiatives.
