Introduction: Laser Ink for Metals
Hello, this is my first time to try making colors on metal's surface with laser machine.
At this time I'm going to try five different metals with black metal ink.
Can it be remove after lasering? Let's see.
Step 1: Prepare Materials
Preparing five different of metals for testing laser ink,copper, brass, aluminum, stainless steel and normal steel.
Step 2: Clean Up the Surfaces
Use wire wool to clean up the metals' surface.
And then rinse the surfaces with water.
After that, dry the surfaces with towels.
Step 3: Mix the Laser Ink
Laser ink information:
Brand: LaserInk starter kit #1 black for metals
Proportion: 1 g powder with 2 ml solvent
Mix them evenly in the bottle with spoon or brush, make sure the blend isn't solidification before you use.
Step 4: Coating Blend
Evenly coat blend on the metals' surfaces (PS:The layer thickness will effect the laser depth of metals' surface.)
Wait 3 to 5 minutes, when the blends color gets from black to gray, the mean it's dry, can continue next.
Step 5: Set Up the Laser Parameters
Laser machine information:
Brand: Epilog mini 40 watt
Set up the laser parameters. (Raster, speed is 5%, power is 100%.)
Step 6: Clean the Surface
Remove the blend of metals' surface with wire wool.
Recycle the dry powder into the bottle, they can be used again.
Rinse the whole surfaces, let it be clean and dry.
Step 7: Finished
The whole process has done, I try to use my nail to scratch the color, no remove anymore, looks very good!
Step 8: Difference Proportion Test
Let's continue do the test about same powder with different solvent proportions.
Left: 1 g powder and 2 ml solvent (Result: Adhesion is best.)
Middle: 1 g powder and 3 ml solvent (Result: Adhesion is neutral between left one and right one. )
Right: 1 g power and 4 ml solvent (Result: Adhesion is general, Laser ink is shedding obviously more or less after scrubbing with brush.)
After coating, the thickness are little difference between 0.005-0.01 mm
We have a be nice policy.
Please be positive and constructive.
