🔎 What's hiding in the threads?

On a medical device, thread geometry can be critical—and some features aren't easy to reach with conventional measurement tools.

Industrial CT scanning lets us look inside a part, while Volume Graphics software helps visualize and measure its geometry in 3D. No need to cut the component open just to see what's going on inside.

Sometimes, the most useful details are the ones you can't see from the outside.

💬 What feature would you want to take a closer look at with CT?

🔎 You’ve got the inspection report. Now what?

A dimensional inspection layout compares selected part measurements with the engineering drawing requirements. But the numbers alone don’t always tell the whole story.

Was the right inspection method used? Were the GD&T requirements interpreted correctly? And what do the results mean for the part?

CMM inspection, 3D scanning, and industrial CT scanning each have a place. The key is matching the method to the part and the question you need answered.

Our latest article explains what goes into a dimensional inspection layout, and what to look for when reviewing one.

New face in the lab! 👋 Meet Chris Bell, the newest member of the Nel PreTech team.

We're giving you a little introduction to the person behind the CT scans. Because while the technology is pretty fascinating, it's the people working with it who bring the results to life.

Take a look, say hello, and help us welcome Chris!

Your turn: What's one thing you always like to know about a new coworker? Their background? Their favorite project? Their go-to lunch spot? 😄

New face. 👋 Same curiosity about what's inside. 🔎

Meet Chris Bell tomorrow!

Any guesses what a CT Specialist gets curious about first? 👀

The outside looks fine. The dimensions check out. So why is the molded part failing?

Sometimes, the clue is hiding inside.

Industrial CT lets engineers inspect internal features without cutting the part open, but there’s more to the process than spotting a bubble in a scan.

A void’s size and location matter. So does whether it’s fully enclosed or connected to the surface. And if you need measurements, the scan has to provide enough detail to support the analysis.

Dave Nelson breaks down what to look for when investigating internal voids in injection-molded parts.

Your turn: Would you investigate the molding process first, or get a look inside the part before deciding where to start?

📐 Ever had a dimension on a drawing that looked completely straightforward...
..until you tried to measure it?

A deep hole.

A hidden internal channel.

An undercut.

A feature buried inside the part.

The CMM may have plenty of accuracy. The problem is that the probe can't physically get where it needs to go.

That's one of the reasons industrial CT can be so useful. Instead of bringing a probe to the feature, CT lets you inspect geometry that's hidden inside the part—without cutting it open.

It isn't really a question of CMM vs. CT.

It's a question of:

What does the part need you to measure?

We take a closer look at the problem—and when CT can help—in our latest article:

What's happening inside a medical device when the flow isn't what it should be?

Sometimes the problem is a restriction, an off-center bore, an internal obstruction, a thin wall, or two passages that don't quite line up.

The challenge is finding it without destroying the device.

Industrial CT can reveal these hidden features in 3D while the device remains assembled, letting engineers investigate the geometry behind unexpected flow, pressure, or leakage results.

And there's an important caveat: CT doesn't measure flow rate or prove a leak. Those still require appropriate functional testing. CT helps investigate the physical geometry that may be causing the result.

See what CT can reveal inside catheters, Luer assemblies, manifolds, pumps, inhalers, syringes, and other medical devices.

What’s Carter doing in there? 👀

No, we’re not fixing a spaceship.

Carter, one of Nel PreTech’s CT specialists, is replacing the filament in our industrial CT scanner as part of routine maintenance.

It’s one of those behind-the-scenes jobs that customers may never see—but it helps keep the system performing reliably and producing the high-quality images and inspection data our engineers depend on.

Because when you’re looking inside a part, the equipment doing the looking matters.

A prefilled syringe can have alignment, positioning, or interface problems that aren't obvious from the outside.

And once you take the syringe apart, you may change the exact relationships you're trying to inspect.

Industrial CT can capture those relationships while the assembly is intact.

For ISO 11040 work, that can mean measuring things like:

🔎 Needle alignment
🔎 Stopper position
🔎 Internal bore geometry
🔎 Component spacing
🔎 Wall thickness
🔎 Hidden interfaces

But CT isn't just about producing a good-looking image. Reliable dimensional inspection depends on the measurement method, surface determination, datums, tolerances, and uncertainty.

The new ISO 11040-8:2026 makes this an especially timely topic for finished prefilled syringes.

WILD WEDNESDAY: Why all those dimples? ⛳

Because when you're chasing performance, even the outside geometry matters.

But the dimples aren't the whole story.

CT scanning lets engineers look at the geometry on the outside while also seeing differences in material density and internal construction—all without cutting the product open.

These two golf balls are a great example. Different internal structures. Different material regions. One even shows damage extending beneath the surface.

For sporting-goods manufacturers, those details can matter when you're engineering for:

🏌️ Distance
🎯 Spin & control
🚀 Launch
💥 Impact performance
🛡️ Durability

Better performance starts with understanding what you're actually building.

If you could CT scan one piece of sporting equipment, what would you choose?
