This kind of images created by lasers on crystals are done very easily. They are created by tiny laser points as displayed in the computer images. An image can be engraved into a 3d laser crystal through laser engraving machine that penetrate through the crystal and coordinate with the positions of tiny points depicting the image.

I’m considering buying a laser engraving machine e.g Epilog Legend or Laserpro Spirit, and need to know whether or not these type of machines can be used within a garage environment. I’m thinking in terms of fire risk etc – I’m considering using a garage that has cans of paint and other flamable items stored. Also, the garage is not heated so could get quite cold sometimes during the year.

Answer:

I would not be especially concerned about the fire hazard — the laser itself must be well contained within the machine. If not, your eyes would be at greater risk than the garage.

I might be concerned about the temperature extremes, however. You should be careful to keep condensation from forming, which is a particularly big problem on suddenly warm days when the garage temperature is lower than the ourside air. In my workshop, I have a small electric heater that keeps the inside a few degrees warmer than the outside.

Temperature could cause problems with:

• lubrication of moving parts, including linear slides.
• condensation.
• laser power levels and power level calibration.

Grease becomes quite stiff at low temperatures, unless it is chosen for low-temperature properties. Increasing the resistance to movement may de-tune the servomotors and increase the positioning error to the point where it becomes useless.

Condensation will hurt you in many ways. Lenses fog. Water gets into the lubrication. Water corrodes steel and aluminum. Water conducts electricity, and alters the behavior of the electronics. Most electronics specifications indicate a wide permitted temperature and humidity range, but require that the conditions be “non-condensing”.

Many laser systems are non-linear with temperature. I don’t know the source of this laser, but if youare operating outside of the customary temperature range, the electronics may not be able to sustain a stable beam. The results and consequences would be difficult to predict.

Depending on how large the unit is, I see that the Laserpro Spirit can consume up to 4400 watts. Be sure you have sufficient electrical capacity.

Personally, I’d love to have one of these machines. Good luck with it, and enjoy it.

Whether you realize it or not, personalized and engraved products are everywhere and someone, somewhere is producing these amazing items and profiting, too.

What about the start up cost of a laser engraving service company? Very affordable! Because a complete laser engraving system that includes computer, software and supplies can be purchased reasonably.

Engrave with laser technology cigars, iPODS, Mac Books, acrylic, counter tops, wood, rubber, stone, leather, fabric or glass to make and personalize unique gift items, recognition awards or keepsakes. Personalize plaques, pens, pencils, or cases. Cut puzzles. Mark tools. Engrave tags. Even etch wine bottles. There are endless possibilities!

Today’s post is a clear example of the different uses of this amazing technology. Below you can see a laser engraving glass with rotary attachment. With the rotary attachment we can engrave most round objects.

Granite is one of the hardest surfaces, and so is perfect for an outdoor plaque, memorial or gravestone. And with laser technology, a photo of the deceased can be added to the gravestone or memorial simply and easily. Granite is usually black but can be found in a dark gray. Black is most often the color of choice, and many feel that the blacker the granite the better stone.

If your desire is engraving your own granite, it is important that you can control carefully your engraver or before buying one to make sure that the engraver you have will cut into granite. Many smaller table top machines do not have the power to etch in granite, so it’s important to check this important point carefully.

Nevertheless, there are many companies, both on the internet and in your neighborhood, who do have the ability to etch in granite. Because granite is heavy, check carefully into shipping costs before you buy—the cost of shipping alone may make it worth the effort to find a local shop who can create the laser engraving in granite that you wish. The newer machines can take a photograph or a piece of complicated art and etch it into the granite, to create a one of the kind, long lasting memorial, plaque or gravestone.

Of course, they’re not doing this for proverbials and giggles; they’d like very much for you to splash out $10k on one of their engraving machines. Now, assuming you’re not planning to engrave every single solitary item you own (plus those belonging to other people) it’s likely cheaper to go somewhere that already has an engraving machine and get them to do it as a one-off, but who cares. I just like seeing an iPhone undergo laser surgery.

Sound like Hollywood? It’s not. It’s the defense industry. After leaving AOL, Shuler was introduced to the technology through a Department of Defense program that pairs successful entrepreneurs with internal projects that it believes have commercial promise. It had been working on the a short-pulse laser project with the University of Central Florida. Schuler formed Raydiance and bought the rights, and has since received $25 million from venture firm Draper Fisher Jurvetson, a $10 million research contract from the US Navy and more angel funding from former Senator Bill Bradley.

According to Raydiance’s website:

“UltraShort Pulse lasers have compelling capabilities that can deliver major benefits to hundreds of lucrative markets. The problem is that that technology is impractical. It’s too expensive. It requires highly trained Ph.D.’s to operate. And while scientists in research labs have shown how USP photonics can revolutionize important applications, today’s USP systems don’t have the throughput they need for most real world applications. Raydiance’s vision is to liberate USP technology from the university lab domain and put it into the hands of hundreds and then thousands of inventors and entrepreneurs. In short, Raydiance’s mission is to make USP technology accessible.

Raydiance’s vision is to see USP technology power a new generation of products and services that revolutionize medicine; transform materials processing and manufacturing; and change the business of defense forever.”

This laser is no Hollywood prop. The technology itself has been around for years. The Petaluma, Ca.-based company’s innovation is that it takes a room-sized laser machine, fits it into a desktop-sized device and provides better software controls. Here’s a little more about the science, from a recent BusinessWeek article:

Unlike conventional lasers found in DVD players, phone networks, and welding shops, USP lasers switch on and off at impossibly high rates–as quickly as once every femtosecond, or a billionth of a millionth of a second. Those concentrated blasts can obliterate any material by literally knocking electrons out of an atom’s neighborhood. That means the lasers can do their job a few atoms at a time if need be, without heating up surrounding material. Since the zapped material is ablated into oblivion, there’s nothing to heat up or melt.

According to the Santa Rosa Press-Gazette, the first commercial applications will be out later this year.

The SF Chronicle points to one company, called EpiRay, that’s licensing the technology to use for cosmetic purposes. Silicon Valley entrepreneur Ajit Shah, who has experience developing surgical systems for SRI International, is raising $500,000 in seed funding. A former Raydiance consultant, he hopes the new device will be able to do things like remove tattoos — vaporizing the dyes that form a tattoo without burning the skin, in contrast with today’s painful techniques. However, the article notes, that he won’t be able to start testing with FD oversight and approval.

Companies like EpiRay are part of Schuler’s plan. He wants Raydiance’s technology to be the source of a new set of commercial laser innovations.

This is quite a leap from Schuler’s job at AOL, where according to a “resume” from 2001, his “proudest accomplishment” was “confounding the technology elite of Silicon Valley, who thought AOL was doomed because it dumbed down the Internet.” What lessons from AOL, we wonder, will Schuler bring to commercializing this space-age technology? Basic scientific research always promises a lot, but is hard to turn into profitable companies. We’ll keep watching.

The depth of the engraving is determined by the laser speed, its wattage and the density of the rubber. For example, a 50 or 100W engraver will engrave the rubber deeper and faster than a 25W machine, which may require a second pass to achieve a similar result. Usually supplied in an A4 size sheet form, a good quality laser rubber is required for engraving stamp dies and must also have suitable compression strength and ink transfer properties.

To assist the engraving process, it is necessary to remove the excess dust which is constantly created by the laser cutting action with an efficient exhaust filtration system. As very few, if any, CO2 laser engraving machines were initially purpose built for engraving and cutting rubber, installing and maintaining an effective dust extraction system pays long term dividends. Mirrors, lenses and any exposed bearing surfaces should be cleaned thoroughly as part of a regular maintenance program. Any neglect in this area will be detrimental to overall trouble free laser operation, as the build up of dust and residue will affect running efficiency and the quality of the finished stamp die. Lasers are controlled directly from a computer, the software drivers supplied with lasers work with many graphic programs such as CorelDraw.

Approximate cost of a 25 watt Laser suitable for stamp making is $40,000

Advantages – Production is computer controlled, custom made stamps can be made easily

Disadvantages – High capital investment, maintenance costs and running will be much higher than vulcanizing or polymer methods of manufacture.

The machine which is used for laser engraving basically has 3 main parts, which are the laser, controller and surface. The laser beam is emitted from the laser, and the patterns are traced by the controller onto the surface.

A laser is so powerful that it can not only engrave, but also cut if necessary. Plasma cutting and woodcarving are techniques that can take place with the help of a high-power laser. Printing on disposable cups, plastic bags, candy bar wrappers and milk cartons is done by a method known as ‘flexo printing’, which is done with the help of laser engraving.

Mostly, laser engraving is used for materials which are “laser-able”, like alloys and polymers. Woodwork, a very beautiful and famous art, is carried out with the help of laser engraving. Here, 10 watts of laser power can suffice to engrave on hardwoods like oak and mahogany. Acrylic plastics and plastic sheets (of soft drink bottles) are also commonly engraved. By the method of conduction, coating can be removed from metal with the help of laser engraving. Diamonds get their brilliance thanks to the process of laser engraving.
