Can a 20W Laser Deep Engrave Titanium?
#LP5 #Titanium #LaserEngraver #metalwork
Is a desktop 20W laser actually enough for “real” metalwork? 🧐
I’m putting the LP5 laser engraver to a brutal test: turning a solid block of Grade 5 Titanium into a high-precision spin coin with a Ruby sphere spin point.
Most people say 20W is too underpowered for deep titanium ablation, but I wanted to find out for myself. Watch the video :
1. Will the ruby survive? I’m aiming for a perfect press fit. There is a “very fine line” here—too much pressure and the ruby explodes (and yes, I actually exploded one during testing!). How do you hit that sub-micron precision on a manual lathe?
2. Can you align a pattern on a 3mm edge by eye? I decided to engrave a coded pattern on the tiny edge of the coin. With only 3mm of space, any misalignment is “horribly visible.” See how I used custom 3D-printed jigs to solve the laser’s manual alignment limits.
3. Why stop at 8 grayscale values? Most people use AI tools for depth maps, but I manually mapped this in Inkscape . Why did I limit it to 8 levels, and how does it prevent “blending” between layers?
4. Is the “Cleanup Pass” a cheat code? I found a way to “clean” the coin using the laser itself. Does the LP5 software handle this, or do you need LightBurn to get that professional, punchy contrast?
5. ⚙️ My specific titanium laser engraving settings？
6. Is 20W enough for production? I share my honest thoughts at the end.
