Filament Management Essentials
Proper filament handling ensures reliable, high-quality prints.
1. Storage & Humidity Control
- Semi-dry Boxes: Store filaments with silica gel packs inside airtight containers.
- Driers & Ovens: Use filament dryers (45300C) for 4-6 hours for PLA/ABS, up to 12 for hygroscopic materials (Nylon, PVA).
- Moisture Indicators: Visual hygrometers help monitor humidity levels (<20% RH ideal).
2. Filament Types & Characteristics
| Material | Print Temp | Humidity Sensitivity | Properties |
|---|---|---|---|
| PLA | 190-2206C | Low | Biodegradable, easy prints |
| ABS | 220-2506C | Low | Durable, warping issues |
| Nylon | 240-2606C | High | Strong, flexible, hygroscopic |
| TPU | 210-2306C | Medium | Flexible, rubber-like |
3. Switching Filaments
- Heat nozzle to current filament's temp. Retract filament completely.
- Clean nozzle: perform cold pull with Nylon or cleaning filament.
- Insert new filament; extrude 20-30mm to ensure clean flow.
- Adjust temperature to new material's spec, run purge tower to stabilize flow.
4. Troubleshooting Moisture-Related Issues
- Signs: bubbles, stringing, rough surface.
- Fixes: dry filament, slow print speed, increase nozzle temp slightly.
