The first time I saw a metal part pop out of a 3D printer, I stared at it like it was alien tech. Big. Heavy. Real. It looked like something made in a massive factory, under tons of pressure, with fire, smoke, and hammers. But nope. It came out of a machine. In a shop. Quietly.
And I couldn’t stop asking questions: How is this even possible? Who checks it? How do you know it’s safe? Can it break? Will it break? And when?
Let’s say you’re printing a bracket for a truck. Or a rocket part. Or something that holds up a bridge.
Are you really going to say, “Looks good to me,” and hope for the best? No way.
In traditional factories, people melt metal and pour it into molds. They’ve been doing it for centuries. And even then, stuff goes wrong.
So what about a machine printing metal layer by layer, in thin strips, with a laser? That’s not just new. It’s kind of scary, which brings us to the question:
- How do you trust a metal part that didn’t come out of a mold?
- How do you prove it’s solid?
- How do you know it won’t fail when it matters most?
FormAlloy says: data. All of it. Every second, every spot, every spark. And they’ve got the numbers to back it up.
Let’s break this down.
How DED Process Monitoring Tracks 3D Printed Parts
FormAlloy’s 3D printers don’t wing it. They watch everything like hawks.
Laser power. Meltpool size. Glass lens heat. All of it? Tracked. Stored. Shown in a report.
“Within one of FormAlloy’s powder- or wire-fed DED printers, sensors are monitoring the meltpool size, the laser power, even the temperature of the optical glass,” writes Stephanie Hendrixson, Editor-in-Chief of Advanced Manufacturing.
And it’s not fluff. It’s facts.
“There’s No One Sensor…”
“There’s no one sensor that is going to be the key to unlocking the whole process,” says Melanie Lang.
So what’s the move? Use lots of them.
FormAlloy’s machines are jammed with sensors. They don’t blink. The data feeds into their brain: DEDSmart.

Charts. Graphs. Alerts. PDFs. You get the full picture. Not a mystery movie.
It Used to Take a PhD
Back in 2018, you had to babysit the machine. It was tricky. Needed experts. No chill.
“The DED machine in use practically required a PhD to operate,” writes Hendrixson.
But not anymore. “We’re past that now,” Lang says.
Now, the machine watches itself. And the smart part? It learned from humans.
FormAlloy asked:
- What were you looking at?
- What made you jump in?
- What caused the problem?
Boom. Those moments became data points.
“Failure Only Gets More Expensive…”
Lang drops a truth bomb: “Failure only gets more expensive the farther along you find the defect.”
If a print takes days, one small mistake = big waste. But if the machine finds the glitch early?
You don’t lose the whole thing. You don’t waste time inspecting the entire part, either.
“You’re always going to have anomalies,” Lang says, “but if you know where those anomalies are, you can avoid situations where parts fail. It’s a more targeted way of doing inspection.”
How Melt Pool Monitoring Improves DED Part Quality
Even the optical glass sends signals. If it gets dirty, it heats up. And that’s bad news.
Why? The laser gets weaker. The meltpool shifts. The part could suffer.
So, DEDSmart steps in. It warns the operator before anything crashes.
As Lang said, “One of the metrics tracked in DEDSmart, for example, is the temperature of the optical glass… FormAlloy can ensure consistent laser power at the meltpool and prompt the operator to clean the glass before it creates a larger problem.”
Crisis dodged. Part saved.
“We Know Exactly How That Additive Part was Formed.”
Lang lays it out: “You can’t see what’s happening inside the mold of a casting… But with DED, we can see every layer. We can track what’s happening at every point. We know exactly how that additive part was formed.”
That’s the mic drop.
FormAlloy doesn’t guess what happened. It knows. With proof. With numbers. With time-stamped data.
You want to question the part? Go ahead. It’s all there.
DED 3D Printed Parts for High Strength Applications

The job? Pull a multi-ton vehicle. The goal? Speed over pretty looks. The result? Solid.
“The print was optimized for speed rather than surface finish,” Hendrixson writes.
Did it pass? Yup. Because they had the data. No mold. No guessing.
Wire DED for Metal 3D Printed Parts
FormAlloy started with powder. Now, they print with wire, too.
Why switch?
- Wire is cheap.
- Easy to move.
- Already qualified for welding.
Even better? You can mix powder and wire. New metals. New tricks.
Formalloy didn’t stop at one way to print. They gave customers options.
Industrial Uses of DED 3D Printed Parts

Who uses them?
- The military.
- Railroads.
- Power plants.
- Labs.
They’re replacing castings. They’re skipping long lead times. They’re done waiting.
And FormAlloy? It’s growing fast.
“It Should Be Easier to Qualify an Additive Part Than a Casting.”
Lang’s not messing around. “It should be easier to qualify an additive part than a casting,” she says.
Why isn’t it?
Because people still trust the old way. Even if it hides problems.
FormAlloy’s way shows everything. But changing minds? That’s harder than building the tech.
“We’re at the point now where it’s more of a people problem — a familiarity problem — than a technology problem.”
Time to Pick a Side
Do you want parts with secrets? Or parts with receipts?
FormAlloy tracks every melt, every zap, and every move. And the proof is in your hands.
The old way is blind. This way? You see it all.
So ask yourself: Would you trust a part you can’t see inside?
Frequently Asked Questions About DED 3D Printing and DEDSmart
1. What are DED 3D printed parts?
DED 3D printed parts are metal components built or repaired with directed energy deposition. The process deposits metal powder or wire layer by layer using a focused heat source.
2. What is DED 3D printing used for?
DED 3D printing is used for metal part repair, large component production, feature addition, surface enhancement, and high value industrial manufacturing applications.
3. What types of parts can DED produce?
DED can produce or repair brackets, tooling, aerospace components, energy parts, structural metal parts, and large components that require strong material properties.
4. How does DEDSmart monitor directed energy deposition quality?
DEDSmart tracks process data during deposition and helps operators see changes in the melt pool, machine conditions, and build performance while a part is being produced.
5. How does process monitoring improve DED part quality?
Process monitoring gives manufacturers real time information about the deposition process. This helps teams detect changes earlier, improve consistency, and document how each part was produced.
6. Can DEDSmart provide traceability for metal 3D printed parts?
Yes. DEDSmart records process information that can support part traceability and quality documentation. Manufacturers can review build data to understand what happened during production.
7. Which industries use DED 3D printed parts?
Aerospace, defense, energy, automotive, heavy equipment, and industrial manufacturing use DED for repair, large metal parts, component upgrades, and specialized production work.
8. How is directed energy deposition different from powder bed fusion?
Directed energy deposition feeds metal directly into a focused energy source and works well for large parts, repairs, and material addition. Powder bed fusion builds parts inside a powder bed and is often used for smaller, more detailed components.
