Intro

The OMG Laser 100W is a high-power fiber laser designed for industrial-grade marking and engraving. It utilizes a MOPA (Master Oscillator Power Amplifier) source, which allows for precise control over pulse duration. This makes it more versatile than standard fiber lasers, enabling it to perform specialized tasks like color marking on stainless steel and high-contrast marking on plastics.

At 100 Watts, this machine is built for speed and depth. It is capable of rapid material removal for deep engraving and can precision-cut thin metal sheets.

Primary Capabilities

  • Surface Marking: High-speed marking of logos, barcodes, and serial numbers.
  • Color & Contrast: Creating a range of colors on stainless steel and "true black" marks on anodized aluminum. Can also anneal metals.
  • Deep Engraving: Removing significant material for 3D reliefs, coins, and stamps.
  • Thin Cutting: Cutting precious metals (gold, silver, brass) up to approximately 1.5mm thickness.
  • Rust Ablation: Remove rust from metals

Compatible Materials

  • Metals: Steel, Stainless Steel, Aluminum, Brass, Copper, Titanium, and Tool Steel.
    • Can engrave through / remove anodizing, powder coat and enamel.
  • Plastics: ABS, Polycarbonate, PBT, Silicon, and other engineered polymers.
  • Other: Slate, stone, and certain dark ceramics.

Important: This laser is specifically for metals and plastics. It cannot process wood, clear glass, clear acrylic, or organic materials.

Instructions

Cleanout Passes

  • For Deburring:
    • You want high speed (e.g., 2000–3000 mm/s), high frequency (80kHz+), and low power (10–20%). Drop the pulse width to a very short duration. This effectively vaporizes the raised slag and cleans the carbon out of the bottom of the trench without cutting any deeper into the base metal.

Post Processing Material

  • There's not a lot of good content on post processing of engraved materials. You're going to find out that many (especially deep) engravings don't look all that great when they first come off the laser. A lot of people put their objects into magnetic tumblers or other automated polishing tools to help knock off slag and smooth out engravings. I will try to find some resources to put here but for now the best advice I can give:
    • The #1 tool of choice for cleaning your engravings is going to be steel wool.
    • Use some machine oil with a stiff bristle toothbrush for light cleaning.
    • For heaver cleaning:
      • Use a Brass brush with water and some burnishing compound
      • Scotch Brite pads on a die grinder
      • Use a random orbital sander starting with 220 grit and moving up (this is the extreme example and will require more polishing and post processing if you do this)
    • High grit wet sand paper is another great tool to use to clean up the surface of your engravings and debur the edges but this only works well on single depth engravings on a relatively flat surface.
    • Don't use microfiber cloths or any fibrous cloth to clean your engravings. The fibers will get all caught up in the microscopic slaggy bits of your engraving and you'll never get them out. Use nylon or polyester napkins if you want to do any wiping of engravings.
    • Dremels and polishing wheels / compounds will also be your friend here.
    • If you're working with materials like polished/mirror finish metals and post-processing would ruin them, opt for more passes at lower power & higher frequency. It'll take longer but you'll get less slag build up and less of a need for post processing.

ToDo

  • Create User Training Outline and Program
  • Build Container box
  • Acquire small file cabinet for storage under desk
  • Fix 2nd monitor
  • Develop Final Rules
  • Program a exhaust fan button to put by the machine
  • Get a webcam to put inside the machine
  • Build a Deburring / engraving cleaning kit:
    • Dremel with polishing compounds and polishing discs.
    • Brass Black
    • Wet Sand Paper
    • Steel Wool
    • Brass Brushes
    • Stiff Bristle Brushes
    • Machine Oil
    • Burnishing Compound
    • Nylon/Polyester Napkins
    • Scotch Brite Die Grinder Pads (Or similar for use with dremel)
  • Save up for Magnetic Tumbler
