1. Recommended Printing Parameters
Based on the GST3D 48kg filament pack, these are the optimal ranges for each material:
| Filament Type | Nozzle Temp. | Bed Temp. | Fan |
|---|---|---|---|
| PLA+ | 180°C - 220°C | 40°C - 60°C | 100% |
| PETG | 230°C - 240°C | 70°C - 80°C | 30% - 50% |
| ABS | 230°C - 250°C | 90°C - 110°C | 0% (use enclosure) |
Tip: Always start with the lowest temperature and gradually increase until you find the best layer quality and adhesion.
2. Essential Calibration Tests
- Temperature Tower: Print a tower with 5°C increments. Observe which section has the best finish and bridging.
- Flow Calibration: Use a flow tower (e.g. 85% to 115%) and measure wall thickness to adjust the extrusion multiplier.
- Retraction Test: Print models that generate stringing and adjust retraction distance and speed.
- Speed Test: Evaluate quality and efficiency at different speeds to find the ideal balance.
- Tolerance Test: Calibrate XY accuracy using press-fit or clearance models.
Why calibrate? Good calibration prevents warping, stringing, poor adhesion, dimensional errors, and ensures reliable results in all your projects.
3. Environment & Best Practices
- PLA / PLA+: Fan 100%, bed 40°C - 60°C, store in a dry place.
- PETG: Fan 30% - 50%, bed 70°C - 80°C, avoid drafts.
- ABS: Nozzle 230°C - 250°C, bed 90°C - 110°C, use an enclosure to prevent warping.
- Humidity: Store filament in sealed bags with silica gel to avoid moisture issues.
Tip: If your filament "crackles" while printing, it has absorbed moisture. Dry it before use for best results.
4. Frequently Asked Questions (FAQ)
- Why is it important to calibrate temperature?
- It improves print quality, layer bonding, and prevents defects like stringing or warping.
- What should I do if I see stringing?
- Lower the nozzle temperature by 5°C or adjust retraction (distance/speed).
- How often should I calibrate?
- Every time you change filament, nozzle, or perform printer maintenance.
- What if my parts have incorrect dimensions?
- Do a tolerance test and adjust flow or X/Y steps as needed.
- How do I prevent warping?
- Use a heated bed, ensure good first layer adhesion, and for ABS use a closed enclosure.
