How to Laser Engrave a Wooden Eiffel Tower (Using the AlgoLaser DIY KIT MK2 20W)
Building a laser-cut wooden Eiffel Tower from scratch is a fantastic DIY project for laser engraving hobbyists and makers alike. With a diode laser engraver like the AlgoLaser DIY KIT MK2 20W, this project becomes not only achievable but a genuinely rewarding hands-on experience. From preparing your 3mm plywood sheets to assembling the final iconic silhouette, this guide walks you through every step, infused with real-world engraver lingo and tips to keep things smooth.
Alright, let’s kick things off. First, grab your 3mm plywood sheet—this is the sweet spot for structural strength and detailed cuts. You want to use a clean, flat, non-warped board. No dents, no knots. This ensures the laser beam maintains a consistent focus throughout the entire job.
Now, lay your plywood flat on the engraving platform of your AlgoLaser DIY KIT MK2 20W. If your engraver includes honeycomb or pin bed supports, use those to minimize scorch marks and improve airflow. If not, make sure the board sits stably and snugly. You don’t want it to shift mid-cut.
Pro Tip: Secure the edges with some low-residue masking tape or edge clamps if your material tends to bow.
Before any cutting magic begins, you must adjust your laser focus. The MK2 comes with a focal gauge—this is your best friend right now.
Move the laser module manually above your plywood, position the focal gauge (usually 20mm for most 20W modules), and lower the laser module until it gently touches the gauge. Once it does, lock it in place.
Now you’re dialed in.
Why does this matter? Because a properly focused beam is the difference between a sharp Eiffel Tower silhouette and a burnt, blurry mess.
Your design file should already be loaded onto the SD card included with the MK2 system—or you can drag and drop it using AlgoLaser's virtual USB disk mode.
Here’s how to find your file:
Tap on the “Projects” tab on the touch screen.
Navigate to “SD Card.”
Locate your Eiffel Tower cut file—preferably in GCode or a compatible format like .nc or .gc.
Make sure your file name is clear—nothing worse than hunting through generically named files like "project1_v2_FINAL_final.gcode".
Best practice: Name it something simple like “Eiffel_Cut_3mm.gcode”.
Now it's time to load your cutting design into the workspace.
✅ Set the Engraving Parameters:
· Material: 3mm Plywood
· Speed: 250mm/min
· Power: 100%
· Passes: 1
· Line Mode: Enabled for vector cuts
This setting ensures your 20W laser engraver slices through cleanly with minimal charring and no need for a second pass.
Drag the Image to the Engraving Area:
Once your file is active, drag the cut pattern onto the engraving grid on-screen. Make sure it’s centered on your board, and confirm the orientation—nothing hurts worse than cutting a design upside down.
Click the Frame Button:
Before you hit “Go,” always, always frame your job. Press the frame button on the screen—your laser head will trace the outer bounds of the design without turning on the laser. This helps confirm:
· The design fits your material
· It won’t overshoot the board edges
· Everything is properly aligned
Spoken Like a Maker: “Measure twice, laser once.”
Everything’s lined up, focused, and framed. Time to hit ‘Start’ and let the MK2 do its thing.
The laser will begin following your vector paths, cutting out each piece of your Eiffel Tower puzzle. You’ll hear a steady hum and the occasional air-assist pump if you're using it.
Let the job finish completely before touching anything.
🧩 Assembly Time:
Once all pieces are cut:
1. Carefully pop them out—some may need a slight push.
2. Lightly sand the edges if needed.
3. Follow your tower’s design plan (most online files include numbered instructions).
4. Use wood glue or tight-fitting tabs to secure parts in place.
🗼 And voilà—you’ve got yourself a miniature wooden Eiffel Tower worthy of Parisian flair!
1. “Do I really need a 20W laser for this?”
If you’re working with 3mm plywood and want a clean, one-pass cut, yes—20W is ideal. A 10W laser could still work, but it might require two or more passes, which increases burn marks and job time.
2. “How long does it take to cut the Eiffel Tower design?”
That depends on the complexity and size of your design, but most average-sized tower projects take 10–25 minutes with the settings we listed. You can speed it up slightly, but don’t sacrifice quality for speed.
3. “Can I use MDF instead of plywood?”
Technically yes—but MDF emits more fumes and can char more easily. Plywood is safer and gives better structural integrity. Plus, it’s prettier, especially if you’re staining or painting your Eiffel Tower afterward.
4. “What’s the best way to clean up burnt edges?”
A quick light sanding with fine-grit sandpaper (220–320 grit) does wonders. You can also use a damp cloth to remove soot—just make sure the wood is dry before you glue or paint.
5. “Why use the frame button? Isn’t it just a preview?”
Framing avoids wasting materials and time. It ensures your design fits the board exactly and isn’t crooked or hanging off the edge. It’s like a rehearsal before opening night.
6. “Is this project good for beginners?”
Absolutely. It’s a fantastic introduction to vector cutting, file setup, focusing, and assembly. Plus, the results are impressive. If you’re just getting started with your laser engraver, this Eiffel Tower build gives you a great confidence boost.
The AlgoLaser DIY KIT MK2 20W Laser Engraver makes wooden model making feel like magic. In just a few simple steps—placing, focusing, selecting, cutting, and assembling—you go from raw plywood to a piece of art that looks like it belongs in a Paris gift shop.
More than that, it teaches you the essentials of laser workflow: design management, hardware calibration, material prep, and safe operation.
Whether you’re creating for fun, gifts, Etsy, or the classroom, this Eiffel Tower engraving project brings history, architecture, and technology together—layer by layer.
So go ahead—load up that SD card, line up your plywood, and start cutting. Your laser engraving journey just leveled up.
