Longer Nano Duo Laser Engraver Real Life Test

[music] [music] Hey everyone, welcome back to the channel. Today I'm really excited

channel. Today I'm really excited because I've been testing something that honestly took me by surprise. The longer

Nano laser engraver. I have spent the past few weeks running it through real projects, trying out all the AI features, playing with different materials, and I think this might BE ONE

OF THE SMARTEST COMPACT ENGRAVER out there right now. So, let me walk YOU THROUGH WHAT IT'S LIKE TO ACTUALLY use this machine, what it can do, and of course, I will show you projects I made

so you can judge for yourself.

So, first, let's talk about the machine itself. Right away, I noticed it's

itself. Right away, I noticed it's compact, PORTABLE, BUT SURPRISINGLY POWERFUL. It has a 20 W blue diode laser

POWERFUL. It has a 20 W blue diode laser combined with a 2 watt infrared laser, which means it can handle almost

anything metals wood leather paper acrylic, bamboo, you name it. The

ingredient speed goes up to 10,000 mm/ second, which is insanely fast for a device this size. And with a motion accuracy of 0.002, 002 mm. The details

came out super sharp. And if you add dual axis extension, which need to be purchased separately, it expands the working area up to 300 by 300 mm. And

also introduces something called smart track vertical cut, which basically keeps the laser beam perfectly vertical even when you are working on large

surfaces or cutting far from the center.

That alone solves one of the biggest problems with small desktop engravers.

[music] But honestly, what makes the Nano do feel next generation is the AI.

Everything runs through Longer's Laser Burn app. The interface is clean, the

Burn app. The interface is clean, the tools are simple, and it's all very beginner friendly. You can actually type

beginner friendly. You can actually type in a text description like a coin-shaped cordish themed pattern with intricate details and the AI instantly generates

designs in different engraving styles.

It sports line art, silhouettes, 3D typography, zentangle, six major styles and it is fast. You literally watch the

design pop up in front of you. The

positioning tools are just as clever.

You place your material on the bed and the AI camera scans it, figures out the shape, the size, the rotation, everything. Then it automatically aligns

everything. Then it automatically aligns your design and show a realtime preview before you even engrave. It also handles focus automatically, WHICH IS PERFECT

WHEN YOU are jumping between a thin piece of metal and a thick chunk of wood. You don't have to adjust anything.

wood. You don't have to adjust anything.

The laser head just does it for you. And

one of my favorite features is the batch mode. If you lay down multiple small

mode. If you lay down multiple small pieces like keychains or metal ts, the machine detects all of them and copies the design onto each one with perfect

alignment. It's actually fun to watch it

work. [music] So, the first thing I did was something simple. I grabbed a black aluminium

simple. I grabbed a black aluminium business card, used the setting on the screen, and engraved an image.

And honestly, look at this. The details

are ridiculously sharp. You can see every line. Let me know what you think

every line. Let me know what you think of this one in the comments because I'm genuinely impressed by how clean it looks.

[music] [music] >> [music] >> Next, I wanted to test the AI generator.

I typed a command into laser burn and it created this beautiful super intricate pattern. I engraved it onto a block and

pattern. I engraved it onto a block and it came out much cleaner than I expected. The contrast is great and the

expected. The contrast is great and the lines are crisp. [music]

>> [music] [music] [music] [music] >> Then I tried making this wooden coin again. I used the AI to generate the

again. I used the AI to generate the artwork and then use the smart camera to just drag and drop the design onto the exact spot I wanted. It's snapped

perfectly into place. The accuracy is spot on, like it knows exactly where that circle is. [music]

[music] Now, this one surprised me the most. The

Nano has this 3D embossing feature using its dial laser, and [clears throat] it automatically adjusts the engraving depth based on color of the image. I

tested it on a 10x 10 cm wooden block.

And I mean, it seriously looks handarved. The depth changes smoothly

handarved. The depth changes smoothly and the details are fantastic. This is

something you usually only get on much bigger machines.

[music] [music] [music] [music] >> [music] [music] >> After that, I tried a fox leather coaster. The design was also generated

coaster. The design was also generated by the AI and leather engraves really nicely on this machine. The result came out clean, dark, and super precise

without burning too deep. It looks like something you would buy from a custom Etsy shop.

[music] [music] >> [music] >> For the next one, I wanted to test engraving on a curved metal surface. So,

I grabbed this stainless steel heat flask. I didn't even use my own artwork.

flask. I didn't even use my own artwork.

I picked a design straight from the bulk in Laser Burn library, which has hundreds of readyto-use files. And the

engraving. Wow. The infrared laser on metal is so crisp. The lines pop and the contrast is beautiful.

[music] >> [music] >> And since Christmas is coming up, I switch back to the blue laser and cut out some Christmas tree decoration from

2 mm plywood. The nano slice right through it cleanly and the edges are crisp. No burned corners, just clean,

crisp. No burned corners, just clean, perfect cuts. [music]

perfect cuts. [music] >> [music] [music] >> And now my favorite test, batch engraving. I place four metal ts on the

engraving. I place four metal ts on the bed. That's it. The Nano Duo scanned

bed. That's it. The Nano Duo scanned them, recognized the shape of each t, aligned the text for every single one, and prepared the batch automatically.

All I had to do was press start. Every T

came out perfectly aligned. This is a lifesaver for people who need to make a lot of identical items. [music] [music] And the last project was on something

very delicate, craft paper. I picked an image from the laser burn library and let the machine run it. Normally paper

burns very easily, but the nano do handle it smoothly without tearing or scorching through. The contrast is great

scorching through. The contrast is great and the details are really nice.

[music] >> [music] >> One thing I really appreciate is how easy it is to switch between the red infrared laser and the blue diode laser.

It is literally one button. The infrared

laser is amazing for metals, plastics, and artificial leather. While the blue laser is perfect for wood, bamboo, paper, food, painted metals, and even

colored glass. This dual laser setup

machine. [music] And I have to mention the dual axis extension, which needs to be purchased separately. Most small engravers start

separately. Most small engravers start cutting at an angle the further you go from the center. But with the nano dual vertical cut technology, the laser stays

perfectly perpendicular no matter where it is. The difference is huge angled

professional finish. [music] So after running all these projects, trying out all the AI features, [music] switching lasers, testing different materials, I can honestly say the Longer

Nano is one of the most advanced portable laser engravers I have ever used. I can honestly say the Longer

used. I can honestly say the Longer Nanoo is one of the most advanced portable laser engravers I have used. It

is fast, it is precise, it is loaded with smart features, and the AI tools genuinely save time. If you are a hobbyist, small business owner, or just

someone who wants a powerful engraving setup that can handle almost anything, this machine is absolutely worth a look.
