Colored annealing keyring with MOPA-Laser

Learn in this tutorial how you can create colored annealing on stainless steel with a MOPA laser.

Preparation

You Will Need

1x Stainless Steel Keyring

Machine Used

SpeedMarker 700
20 Watt MOPA
F254 Lens

For this project, you can use any machine from the SpeedMarker series. You can also use the Speedy fiber or Speedy flexx laser machines.

Important

Depending on what alloy you're using, your results may differ from ours slightly.

To achieve different colours, the pulse width needs to be changed. Therefore, you will only achieve black markings when you use a standard fiber laser (from the SpeedMarker series or a Speedy fiber/flexx machine)

Step by step

Trotec laser software interface linking PDF layers to keyring color annealing parameters

Step 1

Step 1: Design

Firstly, import our template; Or have a go at creating an original design. Import the PDF with layers into the SpeedMark software and assign these parameters and fillings to the object.

Tip:

Define your parameters in advance:

Filling For	Fill Style	Line Distance [mm]	Additional
Text	Cross Lines (Bidirectional)	0.003	-
Letters	Bidirectional	0.03	-
Lines	Bidirectional	0.001	-
Dots	Bidirectional	0.001	Optimise Filling
Wind Rose	Bidirectional	0.001	Optimise Filling
Border	None	-	-
