How to Engrave on Leaves: A Step‑by‑Step Guide

Ever picked up a bright green leaf and thought, “Could this tiny thing become art?”
It can—and you do not need fancy art school tricks to make it happen. With a small desktop laser and a little care, you can turn leaves from your yard into keepsakes or gifts that friends will treasure. This guide shows you how to do it in about an afternoon. We will use the EM-Smart Dual. because it works well on thin, fragile things like leaves, but you can follow the same steps on any laser that handles soft, natural material.
Below, you will find nine clear sections. Each one walks you through what to gather, how to get the machine ready, how to pick the right settings, and how to fix common slip‑ups. The tone stays light, the words stay plain, and the steps stay short. By the end, you will feel ready to grab a leaf and start etching.
Materials you need
Gather everything before you fire up the laser. A tidy workspace saves time and cuts mistakes.
Tip: Keep a damp cloth nearby. A quick wipe removes dust from the leaf or the lens.
Preparing the leaves
1. Pick the right leaf
Walk outside and choose leaves that lie flat in your palm. They should feel a bit firm—floppy leaves sag under the laser beam and wrinkle.
2. Clean the surface
Rinse each leaf in cool water. Pat it dry with a soft towel. Dirt or tiny bugs can block the beam and leave dots in your art.
3. Flatten and dry
If the leaf curls, slide it between two sheets of paper and tuck it inside a heavy book for a day. Dry, flat leaves stay put while you choose a right laser type to do laser processing.

Plug it in: Connect the EM-Smart Dual to power and to your computer with the USB cable.
-
Open LightBurn: If you have not installed it, grab the installer from LightBurn’s site and follow the prompts. The program finds the laser on its own most times.
-
Check focus and height: Place a scrap leaf on the bed. Use the focus gauge or built‑in guide on the EM‑Smart to set the beam height. A sharp focus makes thin, clear lines; a fuzzy spot may scorch.
-
Turn on the fan: The machine holds an internal blower. Make sure it is on so smoke pulls away during a burn. Clean air keeps the beam strong.

3. Size and place: Drag the corners to match your leaf’s shape. Use the grid to judge the space—each square equals one millimeter by default.
4. Center the image: Select the art, then hit the Align Center tool so it lands in the middle of the bed. You can nudge it by arrow keys for minor shifts.
5. Trace if needed: Got a photo? Use Tools → Trace Image to turn it into clean lines that engrave well.
Setting the engraving parameters
Laser work depends on three main numbers:
First pass (outlines)
- Speed: 200 mm/s
- Power: 100 %
- Frequency: 20 kHz
This pass draws the edges. It cuts just enough to mark without slicing through.
Second pass (detail)
- Speed: 500 mm/s
- Power: 100 %
- Frequency: 20 kHz
The faster sweep shades fine detail and smooths rough spots from the first pass.
Note: If your leaf is extra thin, drop power to 80 % and test on a spare leaf first.
Starting the engraving process
1. Place the leaf: Lay the leaf flat on the work bed. Smooth its edges. Tape tiny corners so wind from the fan does not lift it.
2. Frame the job: In LightBurn, click Frame. The laser head outlines the design area so you can check alignment without firing. Nudge the leaf if needed.
3. Hit Start: Press Start in LightBurn. The EM‑Smart Dual zips along at up to 10 000 mm/s, but leaves need slow, gentle passes, so trust the settings you chose.
4. Watch and wait: Keep your goggles on and eyes open. If you see flames or heavy smoke, pause and lower power. Small wisps are normal.
5. Finish and cool: When the job ends, wait ten seconds for any embers to die. Then lift the lid.
Post‑engraving care
1. Remove gently: Peel the tape and slide a thin card under the leaf to lift it. This avoids bending the stem.
2. Seal the art: Lightly mist the front and back with clear spray. Hold the can about 20 cm away and give one quick pass. Let it dry ten minutes, then add a second coat if you like.
3. Show it off: Frame the leaf in a shadow box, mount it on colored card, or press it under glass on a coffee table. The sealant slows fading and keeps veins firm.

Conclusion
Leaf engraving sounds tricky, yet it turns out simple once you break it into clear steps. The dual laser engraver makes it even easier thanks to steady beams, a roomy bed, and user‑friendly software. Each leaf you engrave will look a bit different, and that is the magic—the veins, spots, and curves of nature give every piece its own style.
So, head outside, pick a few sturdy leaves, and fire up your laser. In no time, you will hold a tiny slice of nature that carries your personal stamp.
