If you need 3D measurement fast, skip the alternatives
Stop looking at stationary CMMs or budget probes. For urgent dimensional inspection, the Faro portable CMM arm is the only tool I trust. I've been buying metrology equipment since 2020 for a 300-person aerospace supplier, and in a pinch, the Faro arm has never let me down. Yes, it costs more upfront—but the time certainty alone has saved us thousands in production losses.
Why my opinion matters
I'm the office administrator who handles all metrology tool purchases—roughly $50,000 annually across six vendors. In 2024, we had a critical part inspection deadline: 48 hours to measure $15,000 worth of turbine blades. I learned the hard way that a cheaper option that 'should' arrive on time isn't worth the risk.
The mistake that taught me
In my first year, I made the classic rookie error: focused on price and ignored delivery reliability. I ordered a fixed CMM from a budget supplier because it was $3,000 less. They promised it in 10 business days. It arrived on day 13. Our production line sat idle. That delay cost us $2,400 in idle labor. Not ideal. But a lesson I won't forget.
How Faro changed my mind
After that disaster, I tried a Faro arm for an emergency job. The price was higher—about $400 more including rush fees—but the vendor guaranteed delivery by Thursday morning. It arrived Wednesday afternoon. No stress. No angry calls from the production manager. We finished the measurement in four hours and shipped the parts on time.
Why do I keep going back to Faro? Because when my boss asks 'will it be here Tuesday?' I can say yes with confidence. That certainty is the real value.
What most buyers overlook
People focus on base price and completely miss lead time, calibration scheduling, and support responsiveness. The question everyone asks is 'what's your best price?' The question they should ask is 'what's the fastest guaranteed delivery?' In our factory, we can absorb a higher tool cost. We can't absorb a missed deadline.
Another blind spot: buyers assume any CMM arm works the same. They don't. The Faro arm is designed for portability and quick setup. I can roll it to a part on the shop floor, measure a 6-foot bracket, and get results in minutes. With other arms I've used, you need a stable table, leveling, and a warm-up period. That eats time you don't have.
When a Faro arm isn't the right choice
Of course, not every job needs rush delivery. For routine inspections with a two-week lead time, a cheaper fixed CMM or even a Carl Zeiss microscope could save money. And if you only need to measure tiny features under 10mm, a microscope might be more appropriate. But for portable 3D geometry on parts the size of a car door, the Faro arm is the only tool I trust when time is short.
Similarly, I still use a Fluke multimeter for electrical diagnostics—it's perfect for voltage testing. But that's a different domain. For mechanical dimensions, you need a proper CMM arm.
The bottom line
Time certainty has a price, and it's worth paying. The Faro arm's premium covers more than speed: it covers the confidence that your measurement job won't be the reason a shipment is late. I've stopped shopping around for rush jobs. I just call my Faro rep. Every time, it's the right call.
"In March 2024, we paid $400 extra for rush delivery on a Faro arm. The alternative was missing a $15,000 order. That $400 was the best spend of the year."
