FAQ

Q
Do I need drawings or 3D files?

No. Site photos, reference images or just dimensions are enough — we'll start from 3D design. Design fees are listed separately in the quote.

Q
How long does production take?

Simple prints take same day to 24 hours, 3–7 days with finishing and painting, and 2–4 weeks for exhibition models and dioramas depending on scale. Lead times are stated in every quote.

Q
Can I order just one piece?

Yes, the minimum order is one piece. Unit prices drop for larger quantities such as merchandise, and for orders of several thousand or more we'll review switching to injection molding with you.
