PU20CF is a 20% carbon fiber-reinforced PESU pellet material designed for high-temperature composite molding. It combines the excellent thermal and chemical resistance of PESU with the high strength, stiffness, and low warpage characteristics of carbon fiber. With a heat deflection temperature of up to 200°C, it is ideal for demanding mold applications requiring dimensional stability, durability, and cost-efficient production.

Note: Specimens were printed using a 340°C nozzle temperature, 8mm nozzle diameter, 22mm shell width, and 3mm layer height. The single-layer printing time was 50 seconds with an extrusion output of 14 kg/h at an ambient temperature of 25°C. Specimens were printed with 100% solid infill.
Recommended Printing Conditions
| Parameter | Recommended Setting |
| Drying Temperature (°C) | 150-165 (Equipped with dehumidifying dryer) |
| Drying Time (Hours) | ≥4 |
| Maximum Moisture Content (%) | 0.06 |
| Barrel Zone 1 Temperature (°C) | 300 - 320 |
| Barrel Zone 2 Temperature (°C) | 315 - 335 |
| Barrel Zone 3 Temperature (°C) | 325 - 345 |
| Nozzle Temperature (°C) | 330 - 350 |
Note:
1. Short Pauses:
If printing is stopped for a short duration (e.g., 1–60 minutes), it is recommended to keep the extruder running at a low flow rate (e.g., 2 kg/h) to ensure a continuous material supply and avoid long periods of stagnation or screw idling.
2. Long Pauses
If printing is stopped for several hours, use high-temperature specialty purging material to clean the extruder.
3. Drying Equipment
Drying must be performed using the machine equipped with a dehumidifying dryer.
4. Air Exposure
Once dried, the material should not be left in the air for a long time before entering the printer screw; recommended exposure time should not exceed 15 minutes. Stricter control is required in humid environments.
