Laser Etching Painted Metal

Using a fiber laser system permanent markings can be etched and engraved onto most metals.

Laser etching painted metal.

It should also be noted that coated metals such as anodized aluminum or painted brass do not require pre treatment. Whereas laser engraving only creates black marks laser etching can be used to create both black and white marks. Engraving fabric but the laser burns through the material. The most common etchings and engravings are data matrix codes barcodes logos serial.

Co2 metal marking this quick dry easy to use permanent metal laser ink provides the highest contrast ink in the industry. The only exception is stainless steel which requires laser annealing. If successful the void in the paint could then be used to electrochemically etch the holes in the sha. The first step in avoiding burning fabric with a laser engraving cutting machine is to understand which fabrics can withstand the process and at what temperatures.

Laser marking paints and paint thinners oxidizers. Should give a nice deep etch where the laser removed the masking. After that just removing the plastic laquer with paint thinner. Negative laser etched metal.

Another thing i want to try is covering the steel with paint or spray plastic and burning it off with the engraver then etching with vinegar and an adjustable power supply. Compatible with stainless steel titanium chromium nickel aluminum steel copper brass and the majority of crude metals.

The laser engraving machine is widely used for marking and labeling on painted metal products. The advantage of metal marking with a co2 laser is that the mark is actually produced on top of the metal without removing material so there is no impact on the metal s tolerance or strength. Heartier fabrics such as denim canvas and leather can withstand higher power settings during engraving. Laser etching engraving etching and engraving are the main laser processes used to produce markings onto parts and products.

Needing a prototype done for a shaft encoder steveastrouk asked me to experiment with removal of paint on stainless steel using our laser cutter.
