Description

Atomstack Laser cutters and engravers are powerful and versatile machines. Having said that, there are many types of laser sources such as CO2, fiber optics, UV, and diodes. This article will focus primarily on laser projects and applications for CO2 laser cutters and engravers, but will briefly mention other types.

Most people know that something called a laser "cutter" does cut. That is, the laser cuts all the way through the material.

But what can it cut? Well, it will depend on the type of source and its power output. Typically, low to medium power CO2 laser tubes can cut wood, fabric, paper, leather and other organic materials. They can also cut acrylic, but beware of unknown plastics and PVC as they produce toxic fumes. Fiber lasers can also cut metals and alloys. Cutting is very versatile and can include cutting patterns, parts and prototypes.

This laser engraver project takes simple cuts and then stacks the cut layers to achieve the final product.

Cut out all the components you need to assemble your own spring flower pot. This laser cutter project utilizes laser cutting to create the necessary components to assemble a planter.

Engraving is different from cutting because the laser does not cut through the material, but removes surface points of the material to expose the three-dimensional cavity that creates the image. The same materials that can be cut can also be engraved. The depth of the engraving can be adjusted by running the laser multiple times or by adjusting the power and speed settings.

Engraving is used to create all kinds of stunning textures and images for crafts and novelty items, but engraving also has many useful practical applications. For example, firearms need to display certain manufacturing information that does not fade or dissipate over time. This will create a permanent engraving that does not alter the precision of the tool.

While part of the project involved laser cutting, laser engraving was necessary for the final result.

Marking is when a laser beam alters the properties of a material's surface to slightly alter its appearance and create an image, such as a picture. Instead of breaking down the material like cutting and engraving, this process creates chemical changes in the material. The result is a high-contrast "coloration" on the surface without destroying the material itself. For example, medical tools can be labeled with valuable information without creating cavities where bacteria can gather.

UV galvo lasers are good at marking materials and can be used to mark just about anything. A UV laser will add the perfect finishing touch to any laser cutter project.

Metals and certain other materials have unique properties that allow laser etching. Etching is when the heat generated by the laser touching the surface of the material causes melting, it expands to form raised marks. This is usually done to alter the surface of the metal to change its reflectivity and enhance contrast. This technique works on bare metal, anodized metal surfaces, polymers, and even clay. If this is your type of project, then UV galvo lasers are the way to go.
