3D Laser Scanning and Modelling for Heritage

3D printing and scanning have been on the rise over the past decade. More individuals are recognizing the many benefits that these techniques are able to present to researchers, scientists, engineers, and the average individual. As science continues to fine tune these devices and improve 3D scanning techniques, then the face of the world and its understanding of history could drastically change. With inaccuracies and guesses for how certain items would have looked out of the way, the understanding of history will change.

3D scanning is a highly complex and accurate process. When an item is scanned with a 3D scanner, a fine laser light is shot into the space where the hidden or obscure item is located. The laser light traces over 100 % of the surface of the object recording up to 750.000 different points that are quickly connected to recreate a 3D image of the object.

That 3D image is sent to the 3D scanner where engineers and scientists analyze the object, its purpose, and its origin. Once that data has been collected from the 3D scanner and confirmed, scientists may then decide to use the information that they have obtained to 3D print the object that they have 3D scanned.

How Are These Techniques Used to Model for Heritage?

It is estimated that a significant number of historically important artifacts are located in areas that are hard to reach. Some of these objects are located deep inside of Egyptian tombs. Some of these objects are located at the bottom of the Atlantic Ocean.

Many of these objects have yet to have been uncovered. Scientists estimate that the majority of artifacts are safer where they are located and could be damaged irreversibly if unearthed. That is why 3D scanning and 3D printing are so important to scientists. These scientists can use lasers to reach and trace these hard-to-reach objects. Once they are traced, they can be printed for scientists to examine and understand them.

Many objects are recreated with 3D technology to understand their historical significance. These models can be put on display and used in museums to teach future generations about the various cultures and heritages of certain areas of the world.

Myths About 3D Scanning

3D Printing and 3D Scanning are relatively new developments in the world of technology. 3D printing and 3D scanning have only been in existence for about a decade and are therefore still under investigation by those that do not understand the technology.

3D Printing and 3D scanning are not at all magical. There are hundreds of thousands of brilliant minds working out the details regarding the use and construction of 3D printing technology. Because the techniques and construction involved are so complex, many individuals do not understand how they could possibly work.

3D Scanning and 3D printing do not harm the environment. The lasers used are fine and do not cause harm to the objects that they scan. If these lasers caused harm, scientists and engineers would not be using the technology to discover and recreate ancient objects of historical significance. If these individuals were to use harmful techniques, then the objects would be lost in time forever. 3D Scanning and 3D printing are, to date, the safest way to see these objects without disturbing them.

New Shoes That Only Fit YOU

Shoes are an item of luxury to many individuals around the world. To others, shoes are an absolute necessity needed to protect the feet from diseases and conditions like frostbite, gangrene, and trench foot. In any case, almost every individual on Earth knows what shoes look like, what shoes function as, and what difference shoes can make for those who are on their feet often. Few individuals know that shoes can be 3D printed or what those shoes are capable of doing.

3D printed shoes are shoes that have been created using 3D printing technology. When an item is 3D printed, a machine traces a pattern into an open space using a material such as plastic, metal, or rubber. A design is created by the user, put into a 3D printing machine, and the printer’s laser will both trace and fuse the product. The machine’s laser traces over itself in layers until the desired project has been completed.

Why Create 3D Printed Shoes?

3D printed shoes may simply seem like a luxury item with little value aside from its apparently costly production. 3D printed shoes can offer users far more than just a sense of luxury.

3D printed shoes are created individually for each person and each foot. No two shoes will ever be created in exactly the same way. Those that have created this 3D printing technology understand that feet can even vary in size from one side of the body to the other. In fact, many individuals have feet that are slightly thicker, wider, or longer than the half sizes available to them by many shoe brands. That is why the 3D printed shoe has come into existence.

The 3D printed shoe will eliminate the aches, pains, and complications that are typically credited to the “breaking in” of a brand-new pair of shoes from the store. The creators of this product aim to eliminate painful or hazardous shoes from the market in favor of the shoes that are custom fit for customers. These 3D printed shoes can even be made stronger and lighter for athletes and other active individuals.

The 3D printing concept for shoes is actually quite simple. A customer will enter their shoe store, assuming that that store has adopted this 3D printing technology, have each foot measured, have each foot photographed from various angles, and then the shoes will be 3D printed right in front of them. This custom fit technology makes a brand new, custom-fit pair of shoes available for every customer in a very short amount of time. The 3D printing process is even advanced enough to take information about the individual’s height, weight, and level of activity into consideration as the shoes are being constructed.

3D printed shoes can even be created with a medical purpose in mind. 3D printing can make these shoes orthopedically accurate for certain individuals with medical needs. This process is designed to alleviate pain associated with conditions like collapsed arches and other foot imbalances.

Next Level 3+1: 4D Printing

The future of technology is bright with the early engineering behind Next Level 3+1: 4D Printing technologies. These structures are also known as the early models of 4D printing technological devices. Researchers are currently working out all of the kinds that are found with the 3D printing technology currently in existence. While the current 3D printing technology itself is still in its infancy, researchers, engineers, and scientists are exploring the opportunity to create an even more advanced set of 4D printing devices.

What Makes the 4D Printer More Advanced than Its Predecessor?

3D printing devices are very complex. These machines can convert a 2D image into a 3D object using arms and lasers that work to build layers of material on top of itself. 3D printers are able to build objects as large as buildings as well as objects as small as handheld tools. These printers can even print items like shoes that are tailored to each individual foot and biocompatible structures that can be implanted into the body for reconstructive purposes. It may be difficult to conceptualize that any printing machine could accomplish even more, but 4D printing technology does just that.

The 4D printer is modeled after flowers such as the orchid and the calla lily. These beautiful plant structures are more than pretty flowers to view or smell. These plants are capable of movement and are able to adapt to their environments. Calla lilies and orchids are very sensitive and are known to be receptive to the smallest of changes in temperature, humidity, and sunlight. Scientists are exploring the benefits of being able to manipulate the objects that are printed with a 4D printing device.

Tools for Doctors, Engineers and Many More

These scientists believe that doctors, surgeons, and other medical professionals would benefit from being able to fully manipulate the objects that they use in their practices. This may mean that the tools that a surgeon would use in the operating room would be able to more accurately differentiate between healthy tissue and infected or cancerous tissue that must be removed. If a surgeon were sure that they have removed 100 % of the unhealthy tissue, then this would prevent further surgeries and speed up the process of healing. This may even mean that individuals are completely cured of the ailment that once plagued them. For these reasons, the 4D printer would be valuable to the medical profession.

4D Printers could be used in contexts other than the medical profession. These printers are able to move, shape-shift, and respond to changes in their environment. This would mean that these objects could be used to signal natural disasters of a great variety. These 4D printed objects would be able to retrieve objects that are in water, under water, on land, or in the air that otherwise could not be retrieved. Scientists, engineers, and skilled technicians even have high hopes that these objects would be able to transform the way electricity is conducted or how clothing is created. Designers theorize that there will be a future in smart textiles. Smart textiles are items of clothing that can transform based on humidity, on temperature, and even on requested permeability.

Build a House in Only One Day – 3D Printed Houses

The idea of having a 3D printed house is no longer as farfetched as it has been in years past. Experts state that 3D printing will be the staple of the upcoming technological revolution. It is therefore important to understand what 3D printing technology is and how it can be used to better the lives of all humankind.

3D printing is the process of taking a 2D image and turning it into a 3D object. A high-tech computer takes the 2D image that has been entered and repeatedly traces that image into an open space using thin layers of a specified material. These materials vary from metal to plastics. Each time the 3D computer traces the 2D pattern over itself, the material that is printed is reinforced. Objects of any shape, size, design, or strength can be created with the help of the right 3D printer and materials.

What Are the Benefits of 3D Printed Houses?

The benefits of 3D printing are still under investigation. Manufacturers believe that 3D printing could open the doors for safe and affordable housing in areas of natural devastation. These 3D houses can be printed in as little as 24 hours. This means that temporary housing can be made available while the devastated area is reconstructed. This 3D printed housing option may also serve as a more permanent residence in areas of the world that suffer from overpopulation and lack of housing.

Houses that are created using a 3D printing technique can be taken down as quickly as they are put up. This is an especially useful feature when the occupants move into a more permanent housing establishment, such as would be the case when natural disaster victims move back into their reconstructed homes.

3D printed houses can be redesigned in a quick and efficient way. The materials used to create the 3D printed houses can be recycled completely. Once a house is torn down, then the material is recycled and rebuilt into another 3D printed house. This could easily solve problems like having to replace a weak or damaged wall. The owner or designer of the home may wish to change the texture or the design of the home, and would be able to do so with a 3D printed house.

Cheap and Modern Houses for Everyone

3D printed houses are relatively affordable to create. A 100-square foot 3D printed house can be created in 24 hours. This means that the bill for labor is limited to as little as just one day. Not only can these houses be built quickly, but they can also be created with just one laborer. Only one person is required to load the material into the device that builds the 3D printed home. That means that just one person will need to be paid for labor unless the job is split between a team of members. The materials used to create the 3D printed house are readily available and easily recyclable. When materials do not need to be shipped in from international sources, then the cost tends to be lower for materials.

The entire 3D printed house can be printed on the spot. This will eliminate the need to create portions of the house elsewhere and have them shipped into the construction site. Accidents can be avoided, and construction delays are less likely when the entire process of building the house takes place in one location.

If 3D printed houses encompass each and every one of the benefits listed above, then the cost of manufacturing a home could be cut by as much as 90 %.

3D Print Is Not Limited to Plastic – Interesting Opportunities with Metals

3D metal printing is a process that is quite similar to 3D printing in its original form. 3D printing is traditionally a process that uses a biodegradable material like plastic to create structures or objects like houses or building structures. In other words, 3D printing is the process of taking an image or drawing that is in 2D and recreating that same image in 3D. 3D metal printing only differs in that 3D metal printing uses metal instead of another type of biodegradable material.

3D printing is the process of taking an image or drawing that is in 2D and recreating it in 3D. A giant computer and printer trace over an open space with fine metal material over and over again until the designer sees fit. This printing process can be used to print both small and large 3D objects out of metal in a relatively short amount of time.

How Can 3D Printing Be Used to Advance Humankind?

The possibilities with 3D metal printing are limitless. Metal is a special material that can be soft or sturdy. Certain metals can conduct electricity very well while others are weak conductors. This means that the metals used in 3D metal printing can be varied to meet the purposes of the projects they are meant to create. When a process can be adapted to meet the user’s needs, the project is both efficient and precise. That efficiency and precision is what can be used to advance humankind.

3D metal printing has been used to create solid tools, reinforced metal structures, and strong machines. Items that are 3D printed in metal can even be created so that they have less parts than the typical machine. When there are less parts to a machine, then there are fewer chances of the machine breaking or malfunctioning when stress is put on a certain point of that machine. When tools and everyday useful items are created to be stronger and more efficient, then they last longer. When an item lasts longer, fewer materials are needed to create mass numbers of its weaker counterparts.

What Are Other Benefits of Choosing 3D Metal Printing Over Conventional Methods of Construction?

3D printing in metal allows for customization as the designer or customer see fit. As stated above, some metals are pliable but weak, and some metals are strong but not pliable. This means that sturdier materials would not lend themselves to customization very easily when constructed conventionally. 3D metal printing will allow the designer to create a very sturdy structure without having to sacrifice custom features or designs that he desires.

Standard items can be adapted to fit individual needs. Any metal item, such as a hammer, can be lengthened, widened, shaped, or bent to fit the needs of the individual using it. So, while these items can be conventionally created in mass quantities, it makes sense for users in unique situations to have a metal item 3D printed to fit his needs.

When items are 3D metal printed, the environment benefits. This is because there is no need for large pieces of machinery or factories to produce the 3D metal printed items. When there are fewer factories and chemically-laden processes, then there is a smaller carbon footprint left behind.
