SJ-45 Multi-Material 3D Printer Filament Extrusion Line 15-30kg/h for PLA ABS PETG TPU Color Masterbatch Production
SJ-45 Multi-Material 3D Printer Filament Extrusion Line
The SJ-45 is a versatile multi-material 3D printer filament extrusion line designed for manufacturers who need to produce a wide range of filament types from a single production system. With a robust 45mm barrier screw and 33:1 L/D ratio, it handles everything from standard PLA and ABS to flexible TPU and high-temperature PETG with exceptional consistency at 15-30 kg/h output.
Key Features
- Multi-Material Capability: Processes PLA, ABS, PETG, TPU, HIPS, PP, and PC on a single line with quick material changeover system
- Barrier Screw Design: Optimized screw geometry with barrier flight separates solid bed from melt pool, ensuring complete plastication and eliminating unmelted particles
- Integrated Color Masterbatch Dosing: Precise gravimetric or volumetric dosing unit for consistent color dispersion and masterbatch integration
- Stainless Steel Cooling Tank: Corrosion-resistant 304 stainless steel water bath with adjustable temperature zones for optimal filament roundness
- Color Touch Screen PLC: Recipe management system stores parameters for different materials and colors, enabling one-touch changeover
- Automatic Single Spool Winder: Tension-controlled winding with traverse guide for neat, tangle-free spooling at production speed
