Products / 3D Printing Filament Extrusion Lines
Integrated extrusion solutions for 3D printing filament production, with high-speed and standard-speed configurations to match different production requirements.
Product variants
High-Speed
The RC-50 High-Speed 3D Filament Extrusion Line is a fully servo-controlled 3D printer filament production line designed to process materials such as PETG, ABS, PLA and PLA+ pellets into wound filament spools. It combines a 30:1 single-screw extruder with in-line laser diameter measurement, servo traction and automatic winding to support integrated filament production with reduced manual spool handling.
Standard-Speed
The RC-45 Standard-Speed 3D Filament Extrusion Line is a 3D printer filament production line for materials such as PLA, PLA+, PETG and ABS. It integrates extrusion, cooling, in-line diameter measurement, traction and automatic winding, with configuration options to match production targets, filament diameter and spool requirements.
About
Rongcai provides 3D printer filament extrusion lines for manufacturers producing filament for 3D printing. Our integrated 3D printer filament production line solutions combine extrusion, cooling and shaping, in-line diameter measurement, traction and automatic winding, with configurations selected according to production requirements.
Our filament extrusion equipment range includes two main configurations:
When selecting a 3D printer filament production line, consider the materials to be processed, target output, filament diameter requirements, spool specifications and factory conditions. Materials such as PETG, ABS, PLA and PLA+ can be considered when determining a suitable configuration.
The right filament extrusion equipment configuration depends on your production goals and confirmed technical requirements. Compare the RC-50 and RC-45 specifications to identify the option that best fits your application, or contact Rongcai to discuss your project.
Specification
Final engineering parameters are confirmed for each project. Material and configuration values such as extrusion output, line speed and spool fixing method depend on the selected high-speed or standard-speed setup.
A 3D printing filament extrusion line is a production system that turns polymer pellets into finished filament spools. A Rongcai line combines material feeding, single-screw extrusion, hot-water and cold-water cooling, in-line diameter measurement, servo traction and automatic winding, so one continuous process runs from raw material to a wound spool.
Rongcai filament extrusion lines are specified for PETG, ABS, PLA, PLA+, etc. Other materials are reviewed case by case during the project discussion and are not part of the standard published configuration.
The documented configuration produces 1.75 mm filament with a tolerance of ±0.03 mm. Diameter range and tolerance are confirmed together with the material and output target during the project review.
Line configuration is agreed per project: material, filament diameter, target output, cooling and automation level, spool specification and plant layout all influence the final arrangement. Send the material, diameter, output target and spool size you pack, and Rongcai reviews a matching configuration.
Share the material, filament diameter, target output and spool specification. Rongcai reviews the configuration and prepares a quotation.
