Laser etching metal?

Postby Joe T » Wed Aug 03, 2016 6:25 am

Has anyone tried laser etching metal?
Is the laser capable of doing this?

Tooli's laser has no affect on any of the metals - it's not powerful enough, and arguably not the correct wavelength. The closest you'll get to engraving metal is burning/discoloring the anodizing on aluminum.

Have you considered adding this functionality as an optional extra?

Is Tooli capable of taking a more powerful laser?

I have a number of projects that would benefit from this feature. For example engraving jewellery, or contact details into the personal items like mobile phone, etc.

A new 5W laser diode has recently become available on the market, but even this won't have any affect on metal. It is also not compatible with Tooli's internal circuitry, as it draws too much current.

Laser engraving metal is typically performed using either a fiber laser or YAG laser. You would need to spend a minimum of US5,000 just for the laser unit, and these lasers are typically only found on rather expensive machines.

Slightly off topic, but interesting, I managed to accidentally etch my kitchen granite counter.

Wow! We haven't actually tested the laser on granite, assumed it would have no affect. Thanks for performing that test for us :)
