Color Annealing keyring with MOPA-Laser

Discover how to create coloured annealing on stainless steel with a MOPA laser from Trotec. We take you through a step by step guideline.


Preparation

What you will require:

1 x Stainless steel key ring

Trotec Machine used:

You may also use any other machine of the SpeedMarker series, Speedy fiber or Speedy flexx.

Recommendations:

The alloy on the material used will determine the results on stain less steel. A slight varience is possible. 
You are advised to adjust the width pulse in order to achieve the different colours. Black colour markings can only be achieved when a standard fiber laser of the SpeedMarker Series, a Speedy fiber or Speedy flexx is used.


Step by Step

Step 1: Design

Download our laser ready template or create your own. Import the PDF with layers into SpeedMark and assign parameters and fillings to the object.

Tip:

Define the parameters in advance.

Text cross lines (bidirectional) 0.003 -
Letters Bidirectional 0.03 -
Lines Bidirectional 0.001 -
