Whether you’ve been in metal fabrication over a longstanding period of time or you are just learning the proper uses of design equipment and programming, there’s a series of mistakes that can happen with laser engraving. A laser engraving machine can be a precision machine but there are some common mistakes that you can avoid with future products:
Fabric Engraving Burns
Fabric is one of the items that can be engraved with a laser engraving machine at the right temperature. Tough fabrics like denim and leather can often withstand higher power settings but changing over to materials like cotton can make it more difficult to engrave. Testing out heat settings on garments and with any fabric can be essential when using laser engraving techniques.
If you’re trying to engrave on acrylic and it’s not producing a defined line in a frosty white, it could be wise for you to consider a different engraving technique. If you’re getting clear engraving, you might want to switch over to a cast acrylic for the frosted finish.
Inconsistencies In Glass
When a laser strength glass can often fracture the surface and engrave poorly, for a more smooth finish choose a 300 dpi resolution, change the black in graphics to an 80% black and use Jarvis dithering for smoother finishing. Liquid dish soap in the area that you are engraving can also dissipate heat and improve the chances that the glass may break.
Grain density in the wood can change dramatically and choosing a wood type like Alder or Maple can be a wise choice for consistency. Engrave wood from the bottom up to draw smoke away from the engraving and wipe the surface of wood between engraving tasks if you’re using a stained finish.
The Laser Engraver Is Slowing Down
If your machine is starting to get dirty cleaning out the machine will produce better results and make sure that it can engrave faster. Cleaning off the optics laser, removing residue, and maintaining the performance of your laser can be important.
Keep some of these top mistakes in mind if you would like to improve the performance of your laser engraving machine in the future.
