FAQ
Q: Can you print the entire car body in one piece?
A: For models within 1400mm width, yes. Larger designs can be produced in modular sections and seamlessly assembled.
Q: What’s the surface quality of SLA for large parts?
A: SLA provides a smooth, detailed finish ideal for visual prototypes and presentation models.
Q: Can you make the prototype functional for testing?
A: Yes, we can integrate structural reinforcements and use impact-resistant resins for functional testing.
Q: Do you provide painting and surface treatment?
A: Absolutely—our finishing services include automotive-grade painting, polishing, and UV protection.
Q: How accurate are your life-size models?
A: Typical tolerances are ±0.1 mm, ensuring excellent dimensional fidelity to your CAD designs.
