Here, you can learn how to create black markings on anodised aluminium using a MOPA laser. A name badge is a great example for this kind of application.
You may need to use different parameters to us if you are marking a glossy type of 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 by Step
Step 1: Design
Firstly, import our template; or feel free to create your own. Import the PDF with layers into SpeedMark and assign the parameters and fillings to your object.
Important: If texts are imported from a PDF, they will need to be converted into curves beforehand. Otherwise, SpeedMark won't recognise them as 'text'. Alternatively, you can produce the text directly in SpeedMark to avoid the hassle of converting data.

Step 3: Post Processing
Attach the magnet to the back of the finished nametag. It is now ready to use!
Inspiration
Try using different colours and sizes of anodised aluminium. This will add another element of quality to your nametags.
