Low Volume Manufacturing: Methods and How to Choose
Updated November 13, 2026
Low volume manufacturing is the awkward but valuable middle ground between a one-off prototype and full mass production, roughly 100 to 10,000 units. It's where most new products actually live for a while, and choosing the right method can save thousands. This guide covers the methods, their volume sweet spots, and the one calculation that tells you which to use.
The middle ground
Low volume manufacturing: making a product in small batches, roughly 100 to 10,000 units, using lower-commitment methods than full production tooling. It sits between one-off prototyping and mass production.
Mass production front-loads huge tooling cost to make each part cheap at scale. Prototyping makes one or a few parts at high cost per part. Low volume manufacturing is everything in between: pilot runs, first sellable batches, service parts, and products still settling their design. It matters because it lets you put real products in customers' hands and prove demand before you commit to the biggest cost in the whole project, the production tooling.
The method ladder
Read this top to bottom as a ladder: no tooling and cheap to start at the top, more production-like and lower per-part as you descend.
| Method | Tooling cost | Per-part cost | Volume sweet spot |
|---|---|---|---|
| 3D printing (SLS / MJF) | None | ~$8 to $60 | 1 to ~1,000 |
| CNC machining | None (fixtures only) | ~$60 to $400 | 1 to ~500 |
| Urethane casting | ~$800 to $2,500 (silicone mold) | ~$25 to $150 | ~25 to 500 |
| Aluminum bridge tool | ~$3,000 to $9,000 | ~$0.60 to $2 | ~500 to 10,000 |
Each method trades a bigger up-front cost for a lower per-part cost. 3D printing and CNC cost nothing to start but the most per part; urethane casting adds a cheap silicone mold; an aluminum bridge tool costs more up front but drops the per-part cost to pennies.
The one calculation that decides it
Don't choose on per-part price alone. Choose on total cost for your real quantity:
total cost = tooling cost + (piece price × quantity)
An example makes it concrete. Suppose you need 1,000 parts. An aluminum bridge tool at $7,000 with an $0.85 piece price costs about $7,850. Printing the same 1,000 parts might run $16,000 to $22,000. The tool wins clearly at that quantity, even though printing looked cheaper to start. Run the same arithmetic at your quantity and the right method falls out:
- Under 100 units: print or machine. No tooling is recoverable this low.
- 100 to 500: urethane casting if you need a molded look and color, printing if you don't; bridge tooling starts to compete at the top of this band.
- 500 to 10,000: an aluminum bridge tool, almost always.
Bridge or permanent?
Low volume manufacturing plays two roles. Most often it's a bridge: a temporary way to supply parts and prove demand during the gap between a finished prototype and qualified production tooling, with a clear exit when you hit a volume or a launch date. But for some products, demand never justifies hard steel tooling (specialty items, small niches), and then low volume manufacturing is the permanent strategy, not a stepping stone. Decide which you're doing, because it changes how much you should invest in tooling.
When to graduate to mass production
You move on from low volume when the arithmetic flips: once you're reliably selling thousands and a hardened steel tool's low per-part cost outweighs its high up-front cost (generally tens of thousands of units), production tooling wins. Until then, low volume keeps your risk small and your design flexible. For the full path from a finished design to production, see how to manufacture a product, and for the processes themselves, how products are made.
The short version
Low volume manufacturing makes 100 to 10,000 units with lower-commitment methods, so you can sell and learn before buying a mold. Climb the ladder (print, CNC, cast, bridge tool) as volume grows, and choose by total cost, not per-part price. For the precision-metal option in detail, see low volume CNC machining.

Frequently asked questions
- What is low volume manufacturing?
- Low volume manufacturing is making a product in small batches, roughly 100 to 10,000 units, in the middle ground between one-off prototypes and mass production. It uses lower-commitment methods than full production tooling, so you can sell and learn before, or instead of, investing in a hard steel mold.
- What methods are used for low volume manufacturing?
- Four cover most small hard goods: 3D printing (1 to ~1,000 units, no tooling), CNC machining (1 to a few hundred, no tooling, real materials), urethane casting (about 25 to 500 cosmetic parts from a silicone mold), and aluminum bridge tooling (about 500 to 10,000 production-grade plastic parts). You climb this ladder as volume rises.
- How do I choose a low volume manufacturing method?
- Compare total cost: tooling plus (piece price times quantity), for your real quantity. Under ~100 units, print or machine because no tooling pays back. From 100 to 500, urethane casting if you need a molded look, printing if not. From 500 to 10,000, an aluminum bridge tool almost always wins.
- Is low volume manufacturing permanent or temporary?
- It can be either. For some products, demand never justifies hard tooling, so low volume is the permanent strategy. For others it's a bridge: a way to supply parts and prove demand during the gap between a finished prototype and committing to production tooling.
