Short answer: not really—at least not the kind most people have at home.
Why brass is difficult
Brass is a tricky material for lasers because it:
Reflects a lot of light, especially from common hobby lasers like CO₂ and diode machines
Conducts heat quickly, so it disperses the laser’s energy before it can cut
Can reflect the beam back into the laser, potentially damaging the machine
What can cut brass
Industrial fiber lasers (high-powered, expensive) can cut brass cleanly
These are typically used in professional workshops—not home setups
What home laser cutters can do
Most consumer machines (like diode or CO₂ lasers):
❌ Cannot cut brass
✅ Can engrave coated or painted brass (e.g., anodized or lacquered surfaces)
⚠️ May mark bare brass slightly, but results are weak and inconsistent
Workarounds
If your goal is to work with brass at home:
Use your laser to engrave designs on coated brass sheets
Or switch to tools like:
CNC milling machines
Rotary tools / jeweler’s saws
If you tell me what you’re trying to make, I can suggest a setup that actually works.
