The laser cutting and engraving machine can process different types of materials and thicknesses depending on the source of the laser beam, the power and speed set. The dimensions of our machine’s worktop are 900 x 1200 mm.
The laser beam is conveyed by means of optical assemblies, inside the machine, onto the lens and is here addressed to the work surface. The lasercut reads the lines and settings we have given when designing the file. Before we even start our vector drawing we need to know and have a clear idea of ​​what we want to design.

If I want to cut out the letter A in Times New Roman font we will have the triangular inner part that will be entirely cut from the material if I don’t combine it through bridges to the rest of the letter A.

This applies to every cut part of a project that has no bridges of union with the rest. Unlike engraving, cuts are made even on lines that are not closed. In this way, cracks in the material are obtained. If the lines are closed or coincident, the entire enclosed part is cut, leaving the hole in its place.


For example, if you want a heart-shaped piece to be attached to another support, you need to create the heart-shaped curve. When the material is cut by the laser we will have the support with a heart-shaped hole and a heart-shaped piece. But if we need the heart to be just a contour in our material we should make two curves one inside the other.
You have to imagine the path of the laser on the curves you have drawn and see if it is what you want.

In the case of more complex projects, in which the parts are assembled to obtain the desired object, for example a box or a bird like the one in the cover image, we must also take into account other factors such as the kerf.
But we’ll talk about it in another blog.
