Are you baffled by the term 3D laser engraving? If so, you may find the following FAQs helpful.

Is this how those images get into glass and crystal paperweights?

Well, there are a number of techniques available for putting three-dimensional images (or objects) into the middle of apparently solid objects. Some of them have existed for centuries. However, in a latter part of the 20th century, laser techniques were developed for engraving (or imprinting) three-dimensional images onto initially flat surfaces and then later into the centre of various forms of object. Today, the technique is well established and may well be what is behind those very impressive images you are referring to.

How does it work?

Sadly, space doesn’t permit a full description of all the science involved. Suffice it to say that typically 3D laser engraving works on the basis of taking a three dimensional digitised design file, then using that to drive a high technology laser engraving device that focuses beams on to the inside of the target object. That results in the replication of the design image inside the object concerned.

Can anyone do this?

Not that long ago, this type of 3D laser engraving was restricted to laboratories in universities and then very exotic and expensive manufacturing facilities.

Over time, it has moved into the public marketplace and is now readily available and also a very cost-effective means of producing things such as commemorative gifts and sports trophies. Note, though, that it is still important to have the highest quality design file possible and the machines themselves are significantly expensive - enough so as to mean that they are typically considered professional machines rather than DIY gadgets.

Is there no restriction on the images that can be used?

In a technical sense, no, not really. Some images may, by their nature, be more easily and effectively displayed inside a solid object than others. Of course, the laws relating to copyright will apply to all image reproduction irrespective of the medium concerned.

Can the images be engraved in non-transparent objects?

Yes, providing the material is one that is suitable for the process. However, it might be necessary to question why you would wish to do so – given that the result would be an image inside an object that you couldn’t actually see was there!

Can the image contain advertising or promotional material?

Yes, that would not be a problem in cases such as logos etc. Of course, as mentioned further above, you would need to be sure that you either owned the image concerned or had the right to reproduce it if it was owned by a third party.

Aren’t these images very expensive to produce?

The question of cost is one of the commonest areas of misconception in this entire domain. There is no doubt that in the early days, high quality objects of this type were expensive to produce and perhaps typically beyond the reach of most sponsoring smaller companies or individuals. However, those days are now long past and you may be very pleasantly surprised at how cost-attractive 3D laser engraving can be.
