When to move to small-batch production?
The right time to move to small-batch production isn't a question of timeline, but of real prototype validation.
The signal that shows a prototype is ready to be repeated
A prototype validated in real use, tested under conditions close to its final application and without any major remaining adjustment, is the most reliable signal to consider a small batch. Moving to repetition before this validation often means reproducing the same flaws in greater numbers.
Why small-batch production changes certain technical choices
A material or process choice suited to a single part isn't always the most economical once fabrication is repeated several times. Small-batch production is the point where it becomes worth reassessing these choices — a faster process at unit scale, a different material, or simple tooling that speeds up production without heavy investment.
Small batch doesn't mean full industrialisation
Moving to a few dozen or a few hundred parts remains very different from mass industrial production, which requires expensive tooling amortised over very large volumes. Local small-batch production keeps the flexibility of on-demand manufacturing, with short lead times and the option to still adjust the part if needed.
Frequently asked questions
How many units count as a small batch?
There's no fixed threshold, but it generally refers to a few dozen to a few hundred units.
Do I need to change material when moving to small-batch production?
Not always, but it's worth reassessing depending on the volume and target cost per unit.
Does small-batch production need specific tooling?
Sometimes simple tooling to speed up production, but rarely a heavy investment like in industrial production.
