From Prototype to Small Batch: How Cost Changes as Quantity Grows
An editorial look at balancing process, unit cost, and lead time when moving from a single prototype to a 100-part batch.

Context
For a one-off prototype, 3D printing is usually the fastest and cheapest path. But as quantity climbs to 10, 50, or 100, the equation changes: setup cost spreads across the batch, per-unit time starts to dominate, and the process choice reopens. This article summarizes the decisions to make as quantity grows.
Key Points
- 1–5 parts: FDM/SLA almost always wins; there is no setup cost and iteration speed is high.
- 10–50 parts: print time starts to accumulate. If the geometry allows, request a CNC quote too; the gap may be smaller than you expect.
- 50–100+ parts: expectations for surface and repeatability rise. Compare CNC, casting, or bridge production ahead of tooling.
- Share your quantity range in the RFQ up front; a Creator can give price tiers (e.g., 1 / 10 / 50 parts) in a single quote.
- Before committing to a batch, produce the final prototype in the same material and process as the batch; material changes create surprise behavior differences.
- Include shipping and inspection in the schedule; measuring 100 parts takes real time, just like producing them.
Call-to-Action
A quantity increase is not an order detail; it is a process decision. Share your target quantity range in the RFQ and let Fabberworks Creators respond with tiered pricing and the right process.
