Polytevo Series 3D Printing Filament Extrusion Line
Product Detail
Polytevo Series 3D Printing Filament Extrusion Line (ACS-7008DP) is a laboratory filament extrusion line for Ø1.75 mm 3D printing filament with a Ø20 mm screw (L/D 28:1), heating zones 1/2/3 at RT to 380°C (die head: 380°C), laser diameter measurement and a diameter tolerance of ±0.03 mm.

The ACS-7008DP comprises a high-temperature extrusion unit, a cooling and shaping unit, a diameter measurement unit and a traction and collection unit. Extrusion temperature and screw speed are controlled from a touch screen that displays real-time changes in temperature, speed and pressure during extrusion. The measured diameter controls the traction speed to extrude filament of Ø1.75 mm.

Frequently asked questions
What filament size does the ACS-7008DP make?
The configuration is for Ø1.75 mm filament, with a Ø1.7 mm wire die and a diameter tolerance of ±0.03 mm.
How is the diameter controlled?
A laser diameter measurement system (range 0.1–25 mm, resolution 0.001 mm) feeds the measured diameter back to the traction assembly, which controls the traction speed in a closed loop.
What does the line consist of?
A single screw extruder, a cooling water tank with a water blowing system, and a 3D printing filament auxiliary machine for diameter measurement, traction, traversing and winding.
What are the extruder specifications?
Ø20 mm screw, L/D 28:1, compression ratio 2.4:1, rated speed 0.1–100 rpm (limit 130 rpm), zones 1/2/3 at RT to 380°C (die head: 380°C) and output of approximately 3 kg/h.
What power supply does the main unit need?
AC 380 V ±10%, 6 kW, three-phase five-wire (3P+N+E).
