Colored annealing keyring with MOPA-Laser
Learn in this tutorial how you can create colored annealing on stainless steel with a MOPA laser.
Colored annealing keyring with MOPA-Laser
Learn in this tutorial how you can create colored annealing on stainless steel with a MOPA laser.
Preparation
Required material
Stainless steel key ring
Machine used
- SpeedMarker 700
- 20 watt MOPA
- f254 lens
Any machine in the SpeedMarker series, Speedy fiber or Speedy flexx can be used instead.
Important
The results on stainless steel may differ from the one shown in this example depending on the alloy used.
You need to change the pulse width in order to get different colours. Black markings can only be done when you use a standard SpeedMarker Series fiber laser, a Speedy fiber or a Speedy flexx.
Step by step

Step 1: Design
Either use our template or make a design of your own. Import the PDF with layers into SpeedMark and configure the settings and fillings to the object.
Tip:
Save these settings 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 | Optimize filling |
| Wind rose | Bidirectional | 0.001 | Optimize filling |
| Border | None | - | - |

Step 2: Laser process
Next, input these parameters. These may change based on your laser machine and the laser power available.
Place the workpiece in the machine with the help of border marking.
| Laser parameter | Process | Power [%] | Frequency [kHz] |
|---|---|---|---|
| Text | Marking | 50 | 150 |
| Letters | Marking | 60 | 60 |
| Lines | Marking | 60 | 189 |
| Dots | Marking | 84 | 261 |
| Wind rose | Marking | 54 | 260 |
| Border | Positioning | - | - |
| Speed [mm/s] | Pulse width [ns] | Passes |
|---|---|---|
| 1000 | 200 | 1 |
| 2000 | 200 | 2 |
| 2000 | 8 | 1 |
| 2000 | 100 | 1 |
| 2000 | 100 | 1 |
| - | - | - |

Step 3: Post processing
Post processing is not required.
