Laser cutting and engraving technology has become widely available and serves as one of the main tools in the arsenal of modern makers. Although almost everyone can afford such equipment, not everyone understands how it works and what it is intended for.

The purpose of this article is to briefly familiarize readers with the capabilities of the technology and share tips that may be useful to future owners of laser machines. The TS3 laser engraver from Two Trees will be used as an example.

Diving into the world of laser engraving may seem dauntingly challenging to some, but in practice, it is not at all the case. Even if you have never worked with CNC machines before, you will quickly understand laser engraving, as it is a simple, easy-to-learn process, and also allows you to create interesting things inexpensively.

What is a laser engraver?

As the name suggests, this is a machine for creating patterns and shapes through non-contact processing, the main component of which is a laser emitter that melts, or burns out, or evaporates the working material.

At its core, laser engraving and cutting are manufacturing processes that rely on the use of highly directional, monochromatic, coherent light to cut or engrave a given pattern. It is a non-contact thermal process ideal for working with a variety of materials containing:

• wood
• glass
• paper
• metals
• acrylic

In some cases, the process allows you to obtain high-precision parts without the use of additional tools or special equipment.

Laser machines are often conventionally divided into personal and professional in terms of the power of the emitters. The higher the power, the thicker the cut material can be, and usually, the most powerful machines remain the lot of professional users due to the higher cost, which depends on the power.

On the other hand, relatively low-power machines are quite suitable for amateur purposes, allowing you to work with:

• plastics
• cardboard
• paper
• wood

By the type of emitters, laser engravers can be divided into two categories:

• carbon dioxide
• diode lasers

TS3 is a typical example of a diode laser machine, but with a closed working volume, which is why it is often mistaken for carbon dioxide.

Why do you need TS3?

TS3 laser machines allow you to apply almost any pattern to flat and cylindrical surfaces. Designed with safety and functionality in mind, these engravers are indispensable helpers in private and professional workshops.

Many engravers do not allow working with cylindrical surfaces or require the purchase of additional roller drives. In TS3, this feature is provided from the outset.

In addition, the closed design of the engraver helps to protect the components from mechanical damage. The TS3 is worth getting if only because it is a simple and easy-to-use machine that will suit most people.

What materials can be used with the TS3 laser engraver?

In terms of engraving, the system is suitable for a wide variety of materials including:

• plywood
• bamboo
• leather
• plastics
• acrylic
• stainless steel
• and a variety of paints and oxides.

TS3 is also suitable for cutting plywood, pine planks, leather, acrylic, and cardboard.

For example, with the help of an engraver, you can make various wooden puzzles and paper figures or decorations, as well as mark collars, keyrings, or wallets.

New concepts in 3D printing technology are under test right now. 3D printers are being used to produce equipment, parts and even vehicles that are essential in combat. At this stage, the production is completely for analysis of the hardware. These research and experiment are expected to make the already mighty military even more powerful.

The Navy has a 3D printer technician who is experienced in creating everything from elephants to small trucks with the help of 3D printers. He has even produced model of a boat with 3D printing technology. Its creation took nearly forty hours. However, the same task would have been much more costly and would have taken considerably longer had any other process been involved in it.

Things that typically take months in production can be created in a few days with the help of 3D printing technology now. Undoubtedly, 3D printing is expected to revolutionise manufacturing industry. There may come a day soon when a person visits an automotive parts store for certain gear and asks for a 3D printed model of the same in case of inventory-stock shortage.

3DS recently introduced printers that can be used for production of ceramics. In fact, there are 3D printers that can be used in bakeries as they can easily make decorations and quick additions to confections. What is noteworthy is that the decorations are made of completely edible ingredients and can be the eatable part of sweet delicacies.

The 3D printing machines have quite advanced capabilities. It is true for producer sector, consumer sector and commercial sector. 3D printing business can be very profitable activity as it can potentially attract investment by both commercial establishments and military. Simultaneously, it has showed consumers what and how much can be done right at home. From the capability to create just another item for some work to the scope for a different level of creativity for artists, it seems 3D printers are rightly being onsidered as the next great technological innovation.

On the other hand, 3D printer can be the innovation that may help the US Navy achieve its quest of attaining the apex position among naval defence forces in the World.

The popularity of 3D printing is the result of successful hype as well as lack of reports on facts about the technology. People have developed the expectation that objects can be printed with all the minute details. However, the reality by far is that the objects printed with the help of 3D printer lack details and are not finished to the expectation. A complete object is produced in parts to ensure some fine definition on each part. The parts are then assembled to produce a relatively accurate object.

The mechanism of 3D printing is amazing. A 3D printer uses plaster powder to produce objects layer after the layer and adds colour to it by infusing inkjet ink to each layer. Interestingly, people who have not seen the production of the object believe that it is made of plastic, metal, rubber or other regular material. While objects do look so real, they are not useful for regular functions.

There are exhibitions of items that are complex and serve the expected purpose and are claimed to have been produced by 3D printing. That is deception. The machines that are used to produce those items are extremely expensive and not of the same class as home 3D printer. Moreover, they may also be processed to give them the finish after the print.

In short, objects can be produced at very low cost with the help of 3D printing technique but the product requires going through other processes to be finally ready as a real product. However, the last statement is sadly not the part of most reports on 3D printers. Undoubtedly, the technology is amazing but it needs to be further streamlined for mass use.

3D printing has become so popular a technology that it has managed to reached even those spheres that could hardly be expected to exhibit such modern technology. Those visiting Florida Park can have the opportunity of their images preserved for life as stormtrooper at the Disney Hollywood Studios. This should become a lifetime experience forall big Star Wars fans.

This was possible with the help of 3D printing service that Star Wars Weekend offered at this park. While carbonite figurines were the offering last year, this year looks at the new idea of stormtrooper figure.

This process requires 3D scanning the people visiting the park. The file so obtained is sent for processing at the 3D printing service. Following this, print is obtained and sent to concerned person’s address. The time that passes between the process of scanning with print out reaching the address of the person is only eight weeks. For a stormtrooper figure, the time taken can be little more as it uses colorized ingredients.

Disney’s Research Labs seem happy while being proud of their endeavor. The face scanner used in the procedure is three dimensional and takes one shot only. Spend only $99.95 at the Disney Hollywood Studios’ forthe miniature stormtrooper and miniature carbonite figures.

Whether you are or not a great Star Wars fan, the amazing experience would surely delight every soul that loves technology. After all, it is a lifetime experience, and it should be grabbed.
