Laser Engraving Process

Thursday, June 8th, 2006

You should be able to find several indispensable facts about laser engraving process in the following paragraphs. If there’s at least one fact you didn’t know before, imagine the difference it might make.

Truthfully, the only difference between you and laser engraving process experts is time. If you’ll invest a little more time in reading, you’ll be that much nearer to expert status when it comes to laser engraving process.

Lasers are essentially optical amplifiers. The theoretical background of laser principles as the basis for an optical amplifier was made possible by Albert Einstein. He was the first person to suggest the existence of stimulated emission (the principle on which laser technology is based) in a paper that was published in 1916. The phenomenon of stimulated emission produces a highly monochromatic (one color) and highly coherent light. The first laser was built in 1960 by Theodore Maiman2.

Lasers have had a tremendous impact on numerous industrial processes, ranging from high volume automotive applications to refined electronic applications. These applications include cutting, drilling, welding, etching and even printing. There are different types of lasers. The type used most often for industrial applications is the CO2 (carbon dioxide) laser. This is the gas that is used in combination with two other gasses (helium and nitrogen) to produce the actual laser energy. The CO2 laser also is the type of laser that has been used to engrave ceramic anilox rolls.

The CO2 lasers that have been used to manufacture laser-engraved anilox rolls have seen tremendous improvements during the past decade. Lasers are used to generate pulses of energy, where every pulse is responsible for producing an impression in the ceramic. The pulse rates with which the lasers operate have increased tenfold, allowing anilox roll producers to engrave faster. More important for the end-user, the pulse-to-pulse stability has improved, resulting in engravings that are more consistent.

Although there is no doubt that the conventional CO2 lasers will continue to improve, experiments were started a year ago with a completely different type of laser that does not use a gas (or gasses) such as carbon dioxide to create the laser energy. Instead, it uses a special type of ceramic crystal known as “YAG,” which stands for Yttrium Aluminum Garnet. This type of laser also is referred to as a solid state laser3. The key differences between this laser and the conventional CO2 lasers are the pulse shape and the wavelength.

Laser Glass Engraving

Tuesday, April 11th, 2006

Laser glass engraving is one of the techniques used by successful entrepreneurs. Many businesses are now more creative than ever. Some months ago a germany company called Cerion GmbH went into a popular cruise ship with a compact internal laser glass engraving system. The X2 laser engraver system was installed in the cruise ship for a whole week. The reason to make this movement was to demonstrate this compact laser engraver system was very easy to use, reasonably prices and compact enough to be installed in the ship.

One of the conclusion extracted from this experience is that compact laser glass engraving system are huge business opportunities and their uses are expanding the applications of marking and engraving in many different industry sections, including gift items and memorabilia.

During a whole week this engraver system, instaled in the Eastern Caribbean cruise, offered passengers portrait photo laser engraving in glass. Internal engraving refers to the two- and three-dimensional, sub-surface marking of transparent materials. The glass surface remains completely unaffected by this process. Only 2 men operated the engraver system without any notorious problems for 7-8 hours daily

“Passengers responded very positively,” says Volker Wienkamp, company spokesman.

In fact, he estimates that they got, at least, twenty clients per day. Cruise passengers could choose between a 3D cube with a size of 50 x 50 x 80 mm and a 2D glass plate with a size of 130 x 170 mm . The processing time estimated for each customer was 10-15 minutes.

This compact system was especially designed for mobile use. It can be also used in laser shops. This X2 compact laser engraver system utilizes a Nd:YAG laser (532 nm) to produce up to 1400 points per second with 2W of power. The user controls the system from a laptop (supplied with the system) via a connecting USB cable. The required 3D camera system, also controlled from the laptop, enables users to obtain photographs that are down to a fine level of detail and that have a strong contrast in glass.

The unit is sealed against laser radiation thanks to generously sized filter-glass doors. This way, the sub-surface engraving process, which itself is quite entertaining, can be demonstrated without risk and customers can see how their 3D portrait is created inside the glass.

As you can notice laser glass engraving systems and equipments are becoming a huge business opportunity.

Crystal Laser Engraving

Monday, April 10th, 2006

Last week I visited New York, really an impressive city. I took a walk around a commercial zone with small shops. I saw many typical gifts and souvenirs. You, probably, have one of these things. T-shirts with the I love NY logo, small statue of liberty reproduction and similar stuff. Suddenly I saw one that seemed me very curious. It was a bucket of crystal and inside, in perfect 3D, it was reconstructed the Statue of Liberty, based on small bubbles. Finally I discovered a souvenir without the the bad style of others. You can use this laser engraved crystals as paperweights.

But How can these laser engraving crystals are made?

The first thing is to create the purest bucket of crystal (You can always find purer crystals but you must consider the price as limitating factor) The reason to use pure crystals is clear.In case of using poor quality crystals the failure risk is obviously increased. The phase of laser engraving is carried out using an assembly of 3 laser beams with length of wave “green”, one for each three-dimensional coordinate. With the unified power of these three laser engraving beams or rays, a point is produced. This point is formed by a “melting” of the crystal, forming a microscopic bubble. This repeated process thousands of times in the 3 axes of coordinates produce a perfect three-dimensional image.

Many businesses exist nowadays that are dedicated to this work. They sell smaller machines than they can be used in commercial events and that, even, some of them also include a capturing lens to three-dimensional record your face in 3D inside one of these buckets.
