Using a CNC Laser Cutter to fabricate Signs, Logos & Letters
What is laser cutting?
Laser cutting is a fabrication process which employs a focused, high-powered laser beam to cut material into custom shapes and designs.
This process is suitable for a wide range of materials: Metal Plastics, Acrylics & corrugated plastics Foam including EPS, XPS, EPP, PE, Urethane, EVA
Wood, Plywood & MDF
Laser cutting can produce precise, detailed, complex and smooth parts without the need for custom-designed tooling. It also does not require any fixtures to hold down the material as the laser beam does not apply any force on the material.
Here is the process by which we fabricated a festive 4th of July Wood Sign
We started out by cutting a 0.25" plywood material on our CNC laser cutter.
We cut it in 3 separate sections - Top, bottom and letters.
The laser beam operates at very high temperature so it burns the wood a bit, but this adds a natural charm to the sign.
But, since this is after all a 4th of July sign, we brushed painted all parts in white paint to eliminate the burned look.
We cut a backing to the sign using the same plywood material and placed a black stain gel on front and back using a cloth. We then glued the top, bottom and letters parts on top.
Next, we spray painted all parts - Stars were painted blue, strips were painted red and the writing in white
Here are examples of other materials we cut on our CNC laser cutter, including acrylics, corrugated plastics, foam boards, MDF and plexiglass as well as TEDx thin stage letters - A low cost signs and letters for tighter budget
