Before we look at what a 3D laser engraving machine can do, it is essential that we first understand what laser engraving is all about. Laser engraving is a subgroup of laser marking. It is the use of a laser to inscribe an object with images, numbers, or writings. The process is often confused with laser marking, which is a broader category that entails, foaming, charning, and color change because of the chemical or molecular alteration of the material. Laser engraving technique does not use tool bits or inks, which gets into contact with the object resulting in poor quality output.

3D laser engraving machine

A 3D laser engraving machine contains three main parts: the controller, the laser, and the working surface. The laser acts a pencil. The beam ejected from the laser permits the controller to trace desirable patterns, drawings or writings on to the working surface.

Types of 3D laser engraving machine

· X-Y TABLE

There are three broad genres of 3D engraving machines. The most popular one is the X-Y table. This type of engraving machine has a work surface which is fixed, and the laser optics can either move on the Y-axis or the X-axis. As the laser optics move in any direction, it dictates the laser beam to draw patterns on the material. Depending on the type of engraving one needs, the work surface can move in the opposite direction with the laser optic or move in the same direction.

· CYLINDRICAL WORKSURFACE

The other genre of engraving machines is the cylindrical work surface. This can also entail the flat workspace mounted on a cylinder. Here the laser moves around a helix ant the on and off laser optics results in a bitmap or raster image.

· HYBRID MACHINES

The third genre is where we have a combination of both raster and vector. On this type of machine, both the laser beam and the work surface are fixed. They contain galvanized mirrors which rotate the laser over the work surface.

You can use the machine to enrage practically anything that you want. This can be done by programming or setting the controller to follow a specific path for the laser optic over time. The speed of the laser beam is also a critical aspect in achieving optimal results. You can change the intensity of the shaft to enable flexibility in any design that you want to engrave.

Materials that are compatible with 3D laser engraving machine

· Metals and coated metals

Since many metals are resistant to heat, engraving such materials requires the use of high-density laser irradiation. This can be done using an average 3D laser engraving machine whose power may result in melting or evaporation of the material in question. This is also similar to coated metals.

· Plastics

Different plastics have different properties when it comes to the light absorption spectrum. Laser irradiation can lead to melting or chemical modification of the plastics. Due to this, there was the development of “laserable” plastics. Such materials contain silicate which can transfer excess heat away from the content before it can be deformed.

Other materials that can be engraved by a 3D laser engraving machine include;

· Natural materials such as wood, some types of latex rubber and paper

· Stone

· Glass

· Jewelry

· Pieces of fine art
