Protolabs alternative
Protolabs alternative: speed-first automation versus a machining network.
Protolabs is a digital manufacturer that owns and automates its own production capacity rather than brokering work out. Its CNC service is built around highly automated quoting and programming, which is what lets it ship low quantities extremely quickly. Design rules are correspondingly more constrained than a general job shop: the automation that produces the speed also defines what geometry the system will accept.

Choose them
When Protolabs is the right choice
- You need parts in days, not weeks, and speed outranks unit cost — a stalled design review is more expensive than the part.
- Quantities are small, geometry is machining-friendly, and you want the whole thing to happen without a conversation.
- Domestic manufacturing is required, or import lead time and customs are unacceptable for this particular part.
Consider FabVector
When it is worth switching
- Your geometry falls outside automated design rules — deep pockets, undercuts, cross-drilled internal passages or parts needing 5-axis work in one setup.
- The prototype worked and now you need hundreds or thousands at a cost structure that prototyping automation is not built for.
- You need inspection documentation — CMM reports, material certificates, CoC, FAI — specified per part rather than as a standard package.
- You want a human engineer to tell you how to make the part cheaper, not a system that silently rejects the file.

Structural differences
Only what does not change week to week. Prices, current lead times and promotions are deliberately left out — a stale number is a false claim.
| Dimension | Protolabs | FabVector |
|---|---|---|
| Capacity model | Owns and automates its own factories; work is not brokered to third parties. | Own plant for tight-tolerance and first-article work, plus a 200-factory partner network for breadth and batch capacity. |
| What the model optimises for | Speed and repeatability through automation, within defined design rules. | Geometry and volume range: awkward parts, mixed BOMs and the prototype-to-production transition in one supplier. |
| Design-rule constraints | Automation defines an accepted geometry envelope; parts outside it may need redesign. | Engineer-reviewed: features outside a standard envelope are quoted as a process plan rather than rejected. |
| Documentation | Standardised inspection and certification offerings aligned to the automated flow. | Inspection scope defined per part at RFQ — dimensional report, CMM data, material certificate, CoC or FAI. |
