Laser cutter and engraver are the kind of cool thing after 3D printers which get more and more common. One interesting thing to use a laser engraver (or cutter) is to use it with tesa Laser Labels.
The concept is simple: instead printing labels, engrave them with a laser engraver. The labels are available in different colors, and the laser will remove the acrylic film.
Such labels are commonly used in the automotive industry or as an anti-tamper label (e.g. combined with a serial number or similar).
I managed to get a few samples I could tray with a 50W laser cutter. They already were used, but there was enough unused space I could tray with the laser machine. I used a scotch tape to stick the labels on a piece of plywood:
But engraving with 2% laser power at 20 mm/sec was still to much:
So even with the lowest setting it was burning the material 😦
Increasing the speed did not help:
The laser power with 2% is still to high:
What somewhat worked was raster engraving an image:
Details shown below: For that image, the laser was rastering North-South with 2% power and 300 mm/sec.
This time it did not burn through, but the vertical lines really did not make it. Below the image used (size: 5×5 mm)
So my 50 Watt laser is too powerful for this kind of application. Tesa did not specify the power used/needed, but I think for such an application an engraver in the 5-10 Watt or below should be used. So I admit that my experiment failed, but anyway that would have been an interesting application :-).
Happy Labeling 🙂
