This single-shaft extruder accessory includes a 45# steel screw, a hopper, and two 200W ceramic heating coils. It is designed for quick heat-up and straightforward wiring on a DIY plastic extruder machine. It supports materials such as PE, PP, PS, PVC, POM, PA, PC, ABS, and PET, with a maximum exposure tolerance around 572℉. Best for hobbyists and small workshops looking for a versatile entry-level setup that accommodates a wide material range. A possible limitation is that use depends on compatible tooling and enclosure for safety at higher temps.

TECHTONGDA Filament Extruder ABS PLA (0.1 Inch Die)

TECHTONGDA Filament Extruder ABS PLA Filament Extruder

Check Price on Amazon

The TECHTONGDA model uses three systems: pressing, driving, and heating/cooling. It specializes in producing filament from materials like PCL, ABS, PLA, PETG, TPU, and TPE. The screw rod is nitrogen steel and wear resistant, with a 1-inch screw diameter and a 16:1 L/D ratio. It supports customizable dies to match desired filament diameters (0.1 inch / 2.8 mm). Best for users who want a robust press-and-extrude setup with configurable dies; better for those who need a precise die size but are prepared to manage auxiliary equipment for a complete filament line. Limitation to watch: ongoing need for compatible dies and downstream equipment for finished filament formats.

This 110V variant provides a compact option with two heating coils and a hopper. The 45# steel screw remains high-temperature resistant and supports extrusion of common plastics like PE, PP, PS, PVC, POM, PA, PC, ABS, and PET up to 572℉. Best for small hobby projects where 110V power is standard; avoid this if your workspace requires higher power or larger-scale production without upgrading components.

This version adds a third heating coil, improving fast heat-up and stable temperature control. It includes the same 45# steel screw and a hopper for straightforward material feeding. It is best for users who want enhanced heating capacity to handle a wider range of plastics or higher throughput. A potential limitation is the added heat management requirement to maintain safe operation and consistent output.

ICZW 110V With 3 Heaters Single Screw Extruder

This 110V option includes three heating coils and a single-shaft screw with a hopper. It’s designed for DIY extrusion projects that benefit from stronger heat control and multiple heater zones. Best for compact setups requiring more precise temperatures, but users should verify electrical compatibility and safe enclosure for 3-heater operation.

Banfluxion Single Screw Plastic Extruder

Banfluxion Single Screw Extruder

Check Price on Amazon

The Banfluxion unit serves as a compact core for filament extrusion lines and supports integration with dies, cooling, and haul-off units. It is suitable for producing filaments from PEEK, PCL, ABS, PLA, PETG, and TPE, with a 0-25 RPM adjustable speed and 400W heater capacity. Best for users seeking a central, upgrade-ready module within a broader filament production workflow. Limitation is that it assumes compatibility with downstream extrusion line equipment and a stable power and cooling setup.

Buying Guide

  1. Power requirements: Choose 110V or 220V based on your shop’s electrical infrastructure. Higher heater counts generally demand more robust power delivery and wiring plans.
  2. Heater configuration: More heating zones provide finer temperature control. If you plan to process tough materials, a 3-heater model may offer better stability.
  3. Screw diameter and L/D ratio: A larger screw (e.g., 1 inch) with a high L/D ratio (14:1, 16:1) typically yields better melting and homogenization for a wider material range. Ensure it matches your intended filament diameter and feed rate.
  4. Die and filament diameter: Verify the available or compatible dies. Common diameters like 0.1 inch (2.8 mm) are widely used in hobby and prototyping contexts. Custom dies may extend capability but require additional investment.
  5. Materials compatibility: If you plan to extrude ABS, PETG, PLA, PEEK, or other materials, confirm the unit’s temperature range and corrosion resistance.
  6. Safety and enclosure: Filament extrusion involves high temperatures. Ensure proper shielding, ventilation, and wiring, especially for multi-heater models.
  7. Upgrade pathway: Consider whether the unit can be integrated with dies, cooling systems, and haul-off equipment to form a complete filament production line.
