10W Galvo vs 20W Diode: Which Laser is Better for Engraving in 2026?
When you're shopping for a laser engraver, you'll see two common options: 10W galvo lasers like the Tyvok A1 Mini, and 20W diode lasers from brands like xTool and Ortur. Which one is actually better for your needs?
They both have 10-20W of power, but they work very differently. Let's break it down.
What's the Core Difference?
| Feature | 10W Galvo | 20W Diode |
|---|---|---|
| Beam Movement | Mirrors move the beam (fast) | Whole head moves (slower) |
| Max Engraving Speed | ~8,000-10,000 mm/s | ~2,000-3,000 mm/s |
| Working Area | Usually 100mm x 100mm (small) | Usually 400mm x 400mm (large) |
| Spot Size | Smaller (~0.08mm) | Larger (~0.15-0.2mm) |
| Price Range | $199-$499 | $499-$899 |
Engraving Speed: Galvo Wins Hands Down
This is the biggest advantage of a galvo laser. A 10W galvo can finish an engraving 3-5 times faster than a 20W diode.
Real world example:
- Phone case photo engraving: 60 seconds (galvo) vs 5-8 minutes (diode)
- Dog tag text: 10 seconds vs 60-90 seconds
- Leather bracelet: 20 seconds vs 2-3 minutes
If you're selling engraved products, this speed difference means you can do more jobs per day with less time.
Cutting Power: 20W Diode is Stronger
When it comes to cutting thicker materials, the 20W diode has the advantage:
- 10W Galvo: Cuts up to 3-5mm wood, 2-3mm acrylic (read more about cutting thickness here)
- 20W Diode: Cuts up to 10-15mm wood, 8-10mm acrylic
So if you need to cut thicker materials regularly, the 20W diode is better. If you mostly do engraving with occasional light cutting, the 10W galvo is fine.
Working Area: Diode Gives You More Space
Most galvo lasers have a small working area (typically 4" x 4") because the mirror system can't cover a large area without losing focus.
Diode lasers have large frames, so you get 16" x 16" or bigger working areas for large projects like cutting boards.
Engraving Quality: Galvo has the Edge
Because the galvo beam has a smaller spot size and doesn't have moving mechanical mass, it can do finer detail faster:
- Fine text (2pt) stays readable
- Photo engravings have smoother gradients
- Less vibration, cleaner lines
Who Should Buy Which?
✅ Choose a 10W Galvo if:
- You do a lot of small engravings (phone cases, jewelry, tags)
- Speed is your top priority
- You want the best possible detail on small projects
- You're on a tighter budget ($199-$300)
- You need something portable

✅ Choose a 20W Diode if:
- You need a large working area for big projects
- You regularly cut materials thicker than 5mm
- You don't mind slower engraving for larger size
- You have a bigger budget ($500-$900)

Final Thoughts for 2026
It's not that one is better across the board — it's about matching the machine to your work.
If you're mostly doing small, high-volume engravings and want maximum speed, the 10W galvo is the better choice in 2026. You get faster engraving than a 20W diode for less money.
If you need size and cutting power, go with the 20W diode — just accept that engraving will be slower.
For many small businesses, having both works well: a galvo for fast small engravings, and a diode for large cutting jobs.
