CO2 Laser Engraving

Laser engraving works by having the laser head move back and forth, turning on and off very quickly to produce the engraving. Engraving can be beneficial in many areas over printing and other techniques, in durability, appearance and more.


Types of laser engraving

Laser engraving can be done in a few different ways.

Flat engraving
This is the kind of engraving we do the most. The laser beam is simply turned on and off to produce the image.

Good for: Logos, text, general purpose engraving
Grayscale engraving (dithering)
Grayscale engraving is made by dithering the image (turning it into a lot of small black and white dots). When viewed at normal eye distance this gives the look of a smooth transition.

Good for: Photographs, engravings that needs to smoothly fade between different strengths of engraving
Vector engraving/ scoring
Definitely the fastest way to engrave something. Vector engraving is done by having the laser beam “draw” the engraving as a line, instead of raster engraving the image.

Good for: Quick engravings, subtle engravings, mechanical indicators
3D engraving (variable power)
By varying the lasers power seamlessly you can get a deep 3-dimensional engraving. A grayscale depth map is used to vary the power of the engraving.

Good for: Patterning, faux wood carving, very sharp corners

Equipment

We do laser engraving in-house. Here are the machines we employ at this moment. Keep in mind that the limits of these machines is not always the limit of what we can make. We have a wide network of manufacturing partners to help you realize your project!

Trotec Speedy 400
This piece of Austrian engineering is one of the finest CO2 laser machines on the market. With its ceramic laser tube and high speed servos it can do high quality engravings at blazing speed. It’s a precision instrument, no less.

Power: 80w – Working area: 1000x600mm (or 1000xinfinite using-pass through)
G.Weike LC1390
The kalashnikov. The sledgehammer. This tride and true blocky Chinese creation has served us incredibly well. Hard to beat in terms of getting something done quick. It also uses a DC laser tube, which in some cases can outperform more advanced RF tubes in terms of edge quality.

Power: 130w – Working area: 1300x900mm (or 1300xinfinite using-pass through)

What we can work from

We are very flexible in the way that we can pretty much work from basically anything.

Vector
The best format for laser engraving. We work with almost any format. (ai, eps, cdr, pdf, dxf.. you name it)
Image
A raster image is a close second. Just make sure that the image is of the highest possible resolution, preferably over 300 dpi.
Description
For simple stuff, such as name plates and informational plates, just a description of what you need engraved is okay (text, font, size).

Things to think about

Laser engraving is a relatively straight-forward process. However there are a handful of things to keep in mind:

Engraving depth
We have standard settings for different materials. But on your request we can engrave to different depths by adjusting the power and speed of our machine. Some materials take it differently than others. Feel free to ask!
Residue
Some materials (mostly wood) can leave slight residue around the engraving. It is usually very easy to remove with light sanding, or with the proper solvent.
Unsuitable materials
Some materials, such as PVC releases chloride gases that corrode the optics on the machines, and are therefore unsuitable for laser engraving. However, feel free to ask if you have a material not listed to the left!

Something waiting to be engraved?

We’d be happy to throw it in our laser for you!

    I have watched the video here and also read about all the materials on which this machine works fine. But I would like to know, if I want to engrave any design on a Gold Plate and on a Silver Plate can it be done with this machine?

    For an example, I want the engraving done on my ring and the ring has two parts; One part has a Gold plate and the other one has a Silver plate.

    (Only if this machine can engrave on Gold and Silver) After the engraving process done I will bend the plates and join them by welding and make it a ring. So, Can this machine do my job? I will be very thankful to get a reply.

      Hi!

      We should be able to do that. Cermark marking spray should give a black engraving on silver and gold plating. We can even engrave a sample piece for only the shipping cost if you want.

      Please shoot us an email at info@cnc-design.fi and we’ll figure it out!

    I really think that metal engraving looks amazing. It is so cool to see how they can put the design in the computer and the machine and etch it out. Something like that would be great for a business sign, and it would last a long time.
