Preparation
What you will need
- anodized aluminum
- magnet
Trotec Machine used
- SpeedMarker 700
- 20 W MOPA laser
- F254 lens
You can use any other machine of the SpeedMarker series, Speedy fiber or Speedy flexx.
Please Note
Parameters may vary when marking glossy anodised aluminium.
Creating a black marking is only possible with the MOPA laser. This is the only laser that colors anodized aluminum black through short pulsing. The conventional fiber lasers in the SpeedMarker Series, Speedy Flexx or Speedy Fiber Laser, can only create white marking.

Step 1: Design
Download this template or create your own. Import the PDF with layers into SpeedMark and assign parameters and fillings to the object.
Important: If texts are imported from a PDF, they first have to be converted into curves. Otherwise SpeedMark Software will not recognize them as Text.
| Filling for | Fill style | Line distance [mm] |
|---|---|---|
| Logo | cross lines (bidirectional) | 0.03 |
| Name | Bidirectional | 0.001 |
| Title | Bidirectional | 0.001 |

Step 2: Laser process
Lastly, you can now enter the parameter settings. A varience may occur depending on the laser machine used and laser power.
| Laser parameter | Process | Power [%] | Speed [mm/s] |
|---|---|---|---|
| Logo | Marking | 50 | 2000 |
| Name | Marking | 50 | 1500 |
| Title | Marking | 50 | 1500 |
| Laser parameter | Frequency [kHz] | Pulse width [ns] | Passes |
|---|---|---|---|
| Logo | 60 | 100 | 1 |
| Name | 200 | 8 | 1 |
| Title | 200 | 100 | 1 |

Step 3: Post processing
The magnet can now be fixed on the back of the nametag.
