1. Do you offer warranty services?
"Raise3D offers a one-year standard warranty.Customers can purchase RaiseShield or RaiseShield Pro services to extend the warranty by additinal one year to four years."
2. What is the recommended refresh rate?
| 材料 | 不使用氮气 (Refresh Rate) | 使用氮气 (Refresh Rate) | 备注 |
|---|---|---|---|
| PA12 | 50% | 30% | — |
| PA11 | 50% | 30% | *为确保 PA11 粉末的打印质量，建议将氧气含量保持在 2% 以下。请使用外部氮气源（纯度 >99.9%），例如氮气发生器或氮气罐。如需更多支持，请联系我们。 |
| TPU | ~20% | — | 所需的刷新率较低，约为 20%。 |
| PA NEXT | 50% | 20% | — |
| PA NEXT GB | 50% | 20% | — |
3. How easy or difficult is the material changeover?
Replacing the powder in the printer takes approximately 45 minutes. The C220-P cleaning station requires a similar amount of time; however, due to its powder storage capability, it is recommended to maintain a one-to-one correspondence between the cleaning station and the specific material being used.
4. What is the max. packing density?
"Packing Density: Up to 50% (by weight)
Recommended Range: 10%–20% (to ensure a sufficiently high success rate and avoid sintering quality issues)
Definition of Packing Density (by weight): Weight of Sintered Powder / Total Powder Weigh (the total amount of powder used in a single task)
Important Considerations:
- A packing density exceeding 40% is not recommended.
- Printing solid parts with tight packing may cause overheating and printing failure.
- Packing density should be balanced against the material refresh rate.
- If packing density is lower than the refresh rate → Old powder accumulates, affecting print stability."
5. How is the atmosphere managed inside printer?
The system features a switchable atmosphere mode between nitrogen and air controlled by software, guided by an intuitive wizard. It also includes automatic airflow compensation for both intake and exhaust, along with real-time monitoring of HEPA and activated carbon filter life, as well as the nitrogen supply.
