In this tutorial learn how to create black laser markings on anodised aluminium using a MOPA laser source.

Preparation

Materials required

Anodised aluminium

Any SpeedMarker series, Speedy fiber or Speedy flexx laser machine can be used to create this sample. Please note that MOPA laser sources are only available for SpeedMarker laser machines.

Important information

You might need to use other parameters when laser marking glossy 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

Step 1: Design

Begin by importing our template or creating your own design. Import the PDF with layers into the SpeedMark laser software and assign laser parameters and fillings to the object.

Important: If text is imported from a PDF, they have to be converted into curves before importing. Otherwise the SpeedMark laser software does not recognise it as text. Alternatively the text directly can be produced in SpeedMark.

Filling for	Fill style	Line distance [mm]
Logo	cross lines (bidirectional)	0.03
Name	Bidirectional	0.001
Title	Bidirectional	0.001
