Black Marking Anodized Aluminum Nametag with MOPA-Laser

Learn how you can make black markings on anodized aluminum with a MOPA laser, using this name badge as inspiration.


Preparation

Material needed: 

  • anodized aluminum
  • magnet

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.

Important:

When marking glossy aluminum, you may need other parameters. 

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 by Step

Step 1: Design

Download our design file or create your own. Upload the PDF with the differnt layers into the SpeedMark software and fill out the appropriate parameters and fillings.

It is importnat to note that if texts are improted from a PDF, they have to be converted into into curves. If not, the software will not recognize the design as text. On the other hand, it is also possibel to create text driectly in the SpeedMark software
