One-off prints are useful for learning
A single print can validate fit, finish, customer reaction, and file issues before a team commits to a product page, preorder, or batch plan.
Low-volume production needs repeatable assumptions
Move toward low-volume review when the design is stable, the quantity range is known, the material is selected, and the buyer-facing promise is clear.
Document what changed between runs
Before requesting review, note file revisions, failed prints, preferred material, packing expectations, target deadline, and whether orders will arrive in batches or ongoing demand.
