Description
GRAFMETAL fluid for marking of metals with diode lasers is intended to be used with blue laser engraving machines. Fluid works with machines with a minimum optical power of 1 W, however, for faster processing it is recommended to use machines with at least of 5 W of optical power. The preparation is not intended to be used with CO2 lasers. The layers after being burnt with engraving laser are durable and waterproof, but they can be removed with solvents if needed.

GRAFMETAL fluid for marking of metals with diode laser allows for marking of majority of metal by using diode laser engraving machines with low optical power, even from 1 W!
GRAFMETAL fluid for marking of metals with diode laser is used in a following way:
1. Stir the fluid very thoroughly. If it is too viscous, then dilute it with alcohol. Alternatively one can use water for dilution, but it may increase substantially the drying time.
2. Right after stirring deposit a uniform layer of preparation on the surface of a metal object with a spatula or a hard brush. Wait at least 10 min for drying.
3. Take care of safety when working with a laser and burn the pattern with a diode laser.
4. Rinse or wipe off the unburnt paste.
The paste heats up and cures when irradiated with laser light, what produces a black layer, which gives a marking effect on majority types of metals.
The preparation does not dissolve in water after curing with laser, but it may be removed with a solvent, e.g. with acetone.
GRAFMETAL fluid for marking of metals with diode laser can be used for marking of majority of broadly used metals.
Aluminium processing is not a problem, which is shown below.
The product may be used both for marking already made metal objects as it may be used for preparing new metal plates. To do that it is needed to cut metal sheet first, which may be accomplished with the following methods:
-
sheets up to 1.5 mm (0.06″) thick (including steel): sheet metal guillotine, electric sheet metal shears
-
sheets up to 0.5 mm (0.02″) thick (including steel): manual sheet metal shears/scissors
-
sheets up to 0.25 mm (0.01″) thick (including steel): tailor shears/scissors
GRAFMETAL fluid for marking of metals with diode laser makes it possible to permanently mark the surface of various types of metals, including stainless steel.
The fluid may be easily applied to a metal object, e.g. with a paint brush.
Burning is carried out with ordinary blue laser engraving machines.
The unbrunt paste may be removed after laser processing by wiping or rinsing off with water.
It is possible to produce photographic images after a proper image processing.
It is necessary to note that spot size achieved by using this fluid will be broadened in comparison to what is obtained when engraving e.g. plywood.
The product can be used for black marking of glass and some other non-metalic materials.
Example parameters: blue diode laser (approximately 450 nm) with 5 W of optical power, 100% of power (static M3), 600-3000 mm/min speed
Additional remarks: if the adhesion is too weak, then increase power and/or reduce speed. If the layer is not uniform, then dilute the fluid. Metal objects with higher heat conductivity (e.g. copper, aluminium, brass or thicker objects) should be processed at lower speed and higher power. Patterns burnt with laser may be rinsed off with acetone. Yield up to 5 m2/L.
