1. How long does production take?
Production typically takes 2–5 business days depending on model complexity, material type, and order volume. Custom or large-scale prints may take longer.
2. Can I cancel or modify my order?
Orders can only be modified or canceled before production begins. Once manufacturing starts, the order cannot be changed due to its custom nature.
3. Are all products made to order?
Yes. All products are manufactured on-demand using additive manufacturing (3D printing). We do not hold traditional inventory.
4. Can I request a custom design?
Yes. Custom design requests are accepted depending on complexity and feasibility. Contact our engineering team for evaluation.
5. How long does shipping take?
Domestic shipping typically takes 3–7 business days after production. International orders take 7–18 business days depending on destination and customs.
6. Will I get tracking information?
Yes. A tracking number is provided once your order is shipped. It may take 24–48 hours for tracking data to update.
7. Do you accept returns?
Returns are only accepted for damaged, defective, or incorrect items. Custom-made products are otherwise non-returnable.
8. What if my item arrives damaged?
You must report damage within 48 hours of delivery with photo evidence. We will review and provide a replacement or resolution if eligible.
9. What materials do you use?
We use PLA, PETG, ABS, resin, and carbon fiber reinforced polymers depending on the product requirements.
10. Are 3D printed products durable?
Yes, when used correctly. Each material has specific strength and heat limits. Please refer to our Materials Guide for detailed specifications.
11. Why do I see layer lines?
Layer lines are a natural result of additive manufacturing. They are not defects but inherent characteristics of the process.
12. Are products tested before shipping?
Yes. Every product undergoes basic quality inspection before dispatch to ensure structural integrity and dimensional accuracy.
13. Can I upload my own 3D file?
Yes. We accept STL and OBJ files for custom printing. Files are reviewed for structural feasibility before production begins.
14. Will you fix my 3D model?
Minor adjustments may be made to ensure printability. Complex redesigns may require additional engineering consultation.
