Supplier's note

  1. Technical Breakthroughs:

    • 38CrMoAlA Screw: Achieves 20% longer lifespan than standard alloys, enabling extrusion of abrasive materials like HDPE.
    • PID Temperature Control (Advanced/Pro): Reduces thermal variance by 30%, critical for sensitive polymers like PLA.
    • Modular Design: Swap nozzles or heaters in minutes to switch between filament diameters (1.75mm to 3mm) or material types.

  2. Version Selection Guide:

    • Base Model: Best for labs or educators needing basic PLA/ABS filament production.
    • Advanced Model: Ideal for prototyping firms requiring composites (e.g., WPC) and tighter temperature control.
    • Pro Model: Industrial users benefit from triple chemical resistance and 3.0kW power, enabling high-volume production of PC or PEEK.

With its 38CrMoAlA screw, you can extrude high-torque materials like PA without wear. The Pro’s chemical resistance ensures safe processing of corrosive additives, while the Base Model’s affordability makes it perfect for academic use.
