Lasers: Using them for Signage and Branding Part 1

Laser Engraving is a method that alters the surface of an object to create a certain look or desired design.

Engraving can be done on various materials such as acrylic, wood, and glass. It works by the laser burning through the material to create the design. However, try not to confuse engraving with laser etching that is done by material deformation and is done frequently with metals.

Although these terms are often used interchangeably, there are differences between laser etching and laser engraving. Each type of process has its own applications and attributes that make it ideal for different jobs.

What’s the Difference?

Laser engraving is a process where the laser beam physically removes the surface of the material to expose a cavity that reveals an image at eye level.

• The laser creates high heat which causes the material to vaporize.
• It’s a quick process caused with pulses.
• Several passes are needed to create deeper designs.

Although engraving is a subsect of general laser markings, it still differs in many ways:

• There are three types of laser engraving which includes etching – the difference between them is what the surface is and how much you remove.
• It is common for those who want something personalized or customized.
• Maximum engraving depth is 0.020″
• This is the fastest laser option.
• Can endure high wear.
• Used frequently to engrave serial numbers and logos.
• Can be used on metal, plastic, wood, leather and glass.

Laser etching, which is a form of engraving, occurs when the heat from the beam causes the surface of the material to melt.

• High heat melts the surface of the material.
• The material expands and causes a raised mark.
• The depth in etching is no more than 0.001”.
The differences include:
• Alteration of reflectivity and enhances contrast.
• Removal 0.001″ or less of the material.
• It can be done on ba metal surfaces, polymers and ceramics.

The Advantages of Laser Engraving & Etching

Laser Engraving & Etching allow:

• Precise engraving
• Permanent and imperishable engraving
• High speed of engraving
• Engraving on a wide range of materials.

Materials that can be etched or engraved.

Plywood

Plywood is a wood-based panel obtained by gluing of veneer layers. It is economical and durable. There are different grades of plywood that can be used in creating your signage or engraved item. If the signage is going outside we often defer to marine grade plywood to withstand the outdoor elements.

MDF

Medium-density fiberboard (MDF) is a composite panel of wood fibers to medium density. It’s isotropic, economic and resistant. It rivals the affordability and versatility of plywood and similar engineered wood products. In certain situations, MDF even trumps all the others, because it’s so wonderfully easy to work with. Unlike real wood, MDF has no knots, grain, or warping, and its smooth surface gives way easily to the saw, leaving no splinters, burns, or tear-outs. For light carpentry projects, such as shelving and trim, MDF can be excellent.

It is tough, lightweight and has an excellent light transmission that typically comes in clear format but can be done in different colors with thicknesses. The biggest advantage of Acrylics are the various thicknesses and mounting options that are available. Clear Acrylic works great when illumination or “see through” features are necessary for the final project.
