What is a 3D printing filament extrusion line?▸
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.
What materials can a Rongcai filament extrusion line process?▸
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.
What filament diameters can the line produce?▸
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.
Can a filament extrusion line be customized?▸
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.
