One of the most popular and widely used glass engraving techniques is sub-surface laser engraving, which is used to make 3D crystals or bubble patterns, and they are in high demand.
Lenses that provide a spot smaller than 0.08" are preferred and, at a minimum, you will need 20W of laser power in a diode laser to process the glass.
When working with glass, be careful to provide a lower resolution image, as it helps to engrave each spot at the best distance and prevents the glass from breaking suddenly.
You can engrave both flat and curved glass. To engrave on curved glasses, you will need to use a rolling rotary attachment on the Sculpfun laser engraver.
Some of the glass laser engraving applications are gifts, promotional materials, decorative items and personalized engraving.
Using a layer of material on the glass, such as tissue paper or a plastic cover, will give you a clear engraving. If you use wet tissue paper, you will get a crisp white engraving.
The Sculpfun S30 Pro Max laser engraver can engrave designs directly on mirrored glass, but the engraved part of the mirror will become transparent. It can be used to create some cool looking mirror designs.
After you have finished engraving, you must use a brush to clean it up. I recommend you use a brass brush/wheel as it cleans more efficiently, never use a steel wheel as it will mess up your engraving.
Plastics are easy to engrave and there is a wide variety of plastics that can be engraved with the Sculpfun S10 laser engraver.
Some of the best plastics for engraving are polyetherketone, polystyrene, polyimide, polyamide, polyethylene, polyaryl sulfone, polycarbonate and silicone.
Cutting plastics with a laser produces toxic fumes, and long-term exposure to these fumes can lead to medical problems.
To protect yourself from these fumes, you must maintain an external system to extract and remove toxic fumes through an exhaust unit.
It is also recommended to use the laser in a well-ventilated room with proper safety equipment, such as laser safety goggles, and to be aware of laser safety risks, hazards and control measures.
Other Laser Engraving ProjectsSome valuable creative projects you can work on include customizing and engraving designs on laptops, cell phones, watches, books, decals/stickers, labels and more.
You can purchase and engrave on simple ready-to-use products such as pizza crusts, wooden spoons, wine openers, aluminum change clips, bottle openers, locks, etc.
Make sure that the products you purchase have an engravable surface that you can work with. You can add even more value to these products with a laser engraver.
Final ThoughtsIf you are trying to start a small business with a laser engraver, try to find out what products are in high demand in your community.
Rather than making your own products and then engraving them, it may be better to find customizable products that are already in the market in high demand.
It can be profitable to buy these products in bulk and then enhance their value by laser engraving them to order.
Getting started with laser engraving is easy, but you must be creative with the products you design and engrave to reap the rewards.

The laser tube is the consumable of the laser engraver, so the service life has become the most important purchase index for users. How long can the laser tube work continuously? Many users work 8 to 10 hours a day with their laser engravers. In fact, the damage to key components such as laser tubes is very large. The laser tube that should have been used for more than a year was scrapped after half a year.
Buy laser tubes from a reputable source (HTPOW can be your trusted mall), and you can expect the actual power output of the laser to be around 7~10% higher than the rated value, a Class A, reputable brand, and used for more than 2~ 3 years or more is not uncommon, but first of all making sure you have grade A tubes is the main concern, Sculpfun is a trusted brand, you can tell how popular and reliable it is from how hot the Sculpfun S10 laser engraver is up.
The Hazards of Continuous Operation of Laser TubesSo how long should the laser tube work continuously before resting? The typical lifetime of a laser tube is 5000-10000 hours, unfortunately this is not the number of hours used, but the number of hours since the date of manufacture. Subsequently, the underwriting period is generally 3 to 12 months. However, if you treat your laser tube correctly, you can get years of use. In the case of a relatively small current ratio, it is not a big problem for the laser tube to emit light continuously for 4 hours, and it will not cause too much damage to the laser tube itself. But when the laser tube works continuously for more than 4 hours, the temperature inside the laser tube will gradually increase. When the rate of temperature rise exceeds the heat dissipation rate of the laser tube, the load on the laser tube will increase, and the laser tube will continue to work under high temperature conditions, and its life will decline rapidly. Although the water cooling of the laser tube can take away the internal temperature in time and dissipate heat for the laser tube, the heat dissipation effect is often not enough for long-term continuous use. This is the case with many appliances. Over time, it is too late to dissipate heat and continue to heat up. The laser tube was faulty and couldn't stand the heat. Therefore, it is recommended to turn off the power for a period of time, about half an hour, after working continuously for four hours.
SuggestionIn addition, if the laser tube works continuously for more than 4 hours, the burden on the laser power supply will also increase, and the control board will also be damaged to a certain extent. It is recommended to operate a laser engraving machine. Do not work with high current and high power, which will shorten the service life of key components of laser engravers such as laser tubes. High current or high percentage duty cycle times are not recommended or shortened. Although the laser tube of the laser engraving machine is a consumable item, we always hope to replace it less in order to prolong the service life of the laser tube and reduce the cost of use.
Therefore, the correct use of laser tubes and routine maintenance can ensure a longer service life of the laser engraver.
Speaking of glass engraving, many people will think of the process of glass engraving "laser engraving technology". Laser engraving technology refers to the use of computer control technology as the basis of laser micro-processing medium to make the physical deformation of glass instantaneously melted and gasified under laser irradiation, so as to achieve the purpose of engraving patterns. A laser engraver is an implementation of this technology, and we recommend the Sculpfun laser engraver for a personal hobby or small business.
In daily life, we often see beautiful engraving on some cups, which are basically all made by laser engraving. The Sculpfun S10 laser engraver will introduce the art of laser technology in detail: glass engraving.
Glass is brittle and can easily break during engraving, so glass engraving must be done with great care. Different types of glass have different amounts of lead and are engraved in different ways.
Glass Laser EngravingWith the increase of lead content, the hardness and high-temperature viscosity of the glass decrease, and the glass is more easily broken. Ordinary glass is usually easier to engrave than crystal glass, because crystal glass has a high lead content, reduces hardness and viscosity, and increases the difficulty of laser engraving. Leaded crystals have a different coefficient of expansion than regular crystals, which can cause the crystal to crack or shatter when engraved.
Glass Laser Engraving Process
When the laser beam hits the glass surface, the glass surface is heated and the glass molecules are scattered. In general, the laser can form a frosting or shattering effect on the glass surface.
Crystal Laser EngravingIn order to get a good laser engraving effect, the glass is usually pre-treated: 1. Wet the glass surface, take wet newspaper to cover the glass surface; 2. Use protective foil or tape to cover the glass surface. Pretreatment prevents the glass from being unable to cool due to laser irradiation.
Glass Sandblasting Engraving:An engraving template can be made, the protective coating is applied directly to the glass, and the pattern is traced with a Sculpfun S30 Pro Max laser engraver.
Domed Glass Engraving:A longer focusing wavelength should be selected, because the longer the focusing wavelength, the larger the working area. Then position the focus point at the very center, so that a good engraving effect can be obtained on the periphery of the focus point.
Glass Engraving Coloring:The surface can be cleaned with a damp cloth after engraving and colored with acrylic paint.
Compared with the traditional glass production process, laser engraving technology can solve the production cost and time cost to a great extent, and there are many kinds of engraved patterns and strong design.
HTPOW Lasers has been focusing on laser equipment management for 20 years: laser engravers and 3D printers of various brands.
As the original traditional cutting method, flame cutting has low requirements for processing quality in the past due to low investment. When the requirements are too high, it can be solved by adding a machining process, and the market share is very large.
Now it is mainly used for cutting thick steel plates over 40mm. The disadvantage is that the thermal deformation is too large, the slit is too wide, the material is wasted, the processing speed is too slow, and it is only suitable for rough machining.
Plasma cutting has become the main force of cutting precision, but also a large number of flame cutting precision. The actual cutting accuracy of the domestic top CNC fine plasma cutting machine has reached the lower limit of laser cutting.
When cutting 22mm carbon steel plate, the cutting speed is above 2m per minute, the cutting end face is smooth and flat, and the optimum slope can be controlled within 1.5 degrees. The disadvantage is that the thermal deformation is too large when cutting thin steel plates, the slope is large, there is nothing to do when the precision is high, and the consumables are expensive.
