What is 3D Printing?
Discuss about the Printing Of Three-Dimensional And Its Benefits.
3D printing is additionally named as added substance manufacturing as it alludes to the way toward printing a three dimensional protest of any shape using computerized technology. It is called added substance manufacturing in light of the fact that the printing is finished using layers of materials which are set down in an unexpected way. This procedure is an advanced method which varies in numerous courses from the machine techniques that were generally utilized. The customary strategies depended on the techniques involving expulsion of materials, for example, cutting. This is the reason they were known as subtractive procedures while 3D printing is known as added substance process (de Jong and de Bruijn, 2013).
The 3D printing utilizes the advanced technology and these printers were initially fabricated by China. These printers came in the late 1980’s and as far back as then they have been increasingly utilized everywhere throughout the world. In the beginning of the 21st century, as the computerized technology turned out to be more prominent and propelled, the development in the offers of the 3D printers was extraordinarily watched. The offers of these printers increased in different parts of the reality where they were utilized for new and innovative purposes. Step by step, as the deals and the demand developed, the expenses of these printers fell massively since they were first produced. A portion of the reasons for which these machines were utilized were in industrial utilizations, design, adornments, aviation, engineering, medical, instruction, information systems and numerous others (Richards et al., 2013).
3D printing is the technology to create materials and objects using a sequential layers technique. The materials which are produced by using the layering process can be anywhere in the product life cycle. However, the subtractive methods of manufacturing objects can be used as traditional methods in manufacturing.
The technology that involves printing of three-dimensional objects made its way in the year 1986. It was taken with much seriousness during that time until the year 1990 when great scientists took interest in the technology with a view of change it could bring to the society. Several aspects are involved in the technology with a major thing being the inputs on the design software (Lee & Dai, 2017). The technology has undergone a series of transformation, and it is being applied in different parts of the world impacting the social life of the individuals. Research is still being carried out on further improvement to enable its use in the field of architecture.
History of 3D Printing Technology
The 3D printing technology is a technology that has undergone quite a series of changes since the period of implementation. It involves the creation of printable 3D models with the use of computer-aided design software (CAD) or through the use of what is called a 3D scanner. The modeling process of 3D geometric data does not have a significant difference from the common plastic applied in different parts of the world today. A process known as 3D scanning is applied before printing, and it involves the collection and analysis of digital data in reference to the shape of a real object. The complexity nature of both the manual and automated 3D printable models to normal consumers is what has caused the emergence of the 3D printing places located in different places (Sun et al., 2013).
The most interesting part of the concept is the printing part. Before the commencement of the printing, the file that is known as the STL file must under processing that is a task performed using the slicer software. The slicer does the conversion of the model into several systematic thin layers and produces a command or rather instruction known as the G-code that is now sent to the printer (Walther, 2015). The printer then systematically in accordance to the instructions lays down the layers of the material used t produce the desired object. The major advantage of the technology is that it can produce almost any desired provided the required instruction is well fed to the printer.
Several changes have taken place in the quest to achieve more efficiency in the application of the technology. The first development is on the provision of low-cost printers. In the past, the 3D printers were extremely expensive, and the majority of the people willing to invest in the same could not be able to afford a printer. The other development is a 3D modeling software. In the past, the software used was complex and tough to use which is contrary to the recent times where software development techniques has made it possible for local people to understand how to generate a 3D model (Yazdi et al., 2016). These include software such as Autodesk 123D and Google SketchUp. The other development is on the material that can be used in the printer. After the introduction of the technology, only polymers and plastics could be used as material. Technological advancement and research have made it possible to use other materials such as paper, wax, gypsum, and metals among others.
How 3D Printing Works
There are numerous advantages of 3D printing which is the reason it is tremendously utilized as a part of the present reality. Numerous architects utilize the 3D printing techniques to quickly plan the ideas and transform them into 3D models or fast prototyping. It additionally takes into account the quick outline changes which empowers the fashioners to do their work quickly and easily using the up and coming advancements. The makers are additionally permitted to create the items quickly on demand instead of on expansive run, which likewise increases the administration of the adequate measure of inventory and lessens the distribution center space (Romano, 2013).
3D printing techniques can help the general population living in remote areas to create the articles that would be inaccessible to them generally. 3D printing must be an onetime cost on the grounds that once the planners and businesses have purchased the machinery for 3D printing; they can spare a great deal of material and cash which is utilized as a part of subtractive techniques of manufacturing. The material in this strategy is penetrated, cut and shaved off; subsequently crude material can be squandered. 3D printing is favored additionally on the grounds that it enables the articles to change the idea of manufacturing for example by allowing the clients to download the documents utilized as a part of printing 3D protests in their own particular homes including electronic devices (Vijayavenkataraman, Fuh and Lu, 2017).
3D printers can make numerous models and models from the PC helped plan drawings. Architects to a great extent utilize these printers to make models, models and additionally the final items. There are numerous things that come in the scope of these items. These things are shoe outlines, wax castings for adornments making, furniture plans, instruments, blessing things and toys. There are a few different things utilized as a part of the day by day life of individuals which are created using 3D printing techniques. This causes the fashioners to make new plans, quickly create them and make them alluring for the clients (Rouiller et al., 2013).
Not only these industries, but rather the flying and car industries likewise to a great extent utilize the 3D printing techniques to create parts. Additionally, craftsmen utilize these printers to influence figures and planners to make models for their activities. Archeologists make 3D sweeps of delicate ancient rarities and then print the duplicate of the question. Similarly the scientistss copy, for example, a skeleton of the dinosaur for show. 3D printing is utilized by the doctors to make hearing guides, prosthetics, bone drafts, counterfeit teeth and they can likewise imitate models using 3D techniques of organs, and internal structures of the body appeared in CT outputs to get ready for medical procedures.
Advantages of 3D Printing
To begin with this is an additive manufacturing technology. It is used in various applications namely production applications, modeling, and prototyping. The fused deposition modelling also is one of the methods employed in 3D printing. The technology has existed drawing back from 1980 by Scott cramp; the technology has proved effective over years by applying the additive principles in its operation. It works by laying materials in layers, and a metal wire or filament made of plastic is relaxed from a coil hence distributes materials to produce apart (Hoy, 2013). The technology is termed as simple to explore and clean; it also supports thermoplastic grade production that are mechanically and environmentally stable.
An added substance technology the 3D printing, objects are not created from the specific option of material rather than the molding of subtractive machining. 3D creates objects from cross-areas in the new 3D printer they are worked as a solid course of action or from subcomponents. The new Hp 3D innovations have two awesome highlights they have machines that smooth parts with excellent subtle elements and additionally create excellent quality (Visser et al., 2013). Hp Multi-fly combination technology is the new brand and technology; it offers lucrative administrations, for example, excellent speed and great control over properties and parts found in other 3D printing techniques. It works through a format of a thin layer of material in the working region. Moreover, it has a carriage that has a Hp warm Inkjet connecting left and right, printing along the zone of work. It transforms each layer course of carriages for ideal profitability.
Though the overall production of products using 3D is cheaper as compared to conventional techniques, people have to incur the cost of buying the printers and a computer in order to be able to use the technology. The fact that new types or designs of 3D printers are been developed everyday can be extrapolated to mean that these printers are developed in different sizes. A particular size of a printer can therefore only print a product of a size that can fit in that specific printer. In other words, an individual in need of producing products or merchandise for commercial purpose, and of different sizes, has to buy different sizes of printers. This can be very expensive (Barker et al., 2013).
There are also legal issues that arise in reference to 3D printing. An example given by (Barker et al., 2013) focus on liability issues, for instance when a printed item causes damage or injury to a human being or property. Questions arise on who ought to pay for damages in such a case. Due to counterfeiting, a manufacturing company could be wrongly held accountable and end up spending millions in litigation fees.
Applications of 3D Printing
Nowadays, the development of technology always brings a lot of surprises and incredible things to people. With the continuous development and innovation, technology gradually affects every aspect of human life. Whether people are working or in everyday life, people cannot live without the support of technology. Although the technology has begun to make so much contribution to the business field, when 3D printing technology appeared, it allowed people to experience the life-change by introducing the next generation technology.
Whatever we create utilizing 3d printing technology, similar to restorative field builds up the organs or military creates automatons or specialists create development gadgets, it will be relatively exceptionally modest than the first ones and with a few changes in the technology, it will be extremely enhanced later on. 3D printing techniques are advancing day by day but yet they have not been advances enough that they be used for mass production. Currently their speed is slow and this limits their usage. There are many tools used to overcome this problem such as by using machines that combine with printers and increase their speed. This can be to print the multiple colors, multiple prints at the same time and using different polymers. The aim is to increase the printing speed while printing multiple objects and using less cost of capital than two machines as a single controller may be used. New printers also offer two print heads in order to increase the speed and production quantity at one time.
The 3D printing technology is largely being used worldwide. It initiated in America but it has a widespread range of its machinery and usage in China and Australia. Engineers and industrialists have used the new technology in China as the revolutionary 3D printing manufacturing was advancing. In order to initiate the advanced technology of 3D printing all over a China, many universities such as Beijing University is working on a research which would examine the industry sources that are a breakthrough for the 3D printing techniques to produce large components for aircrafts.
Conclusion
To sum up, 3D printing can overcome some difficulties which traditional manufacture cannot conquer, and produced a more complex structure. Indeed, in recent years, with the development of technology, 3D printing has pioneered a breakthrough on medical applications. This is mainly because the medical industry, especially in the field of restorative medicine, needs significant character customization, little standard quantitative production. Thus, personalized, small batch and high precision is exactly where the 3D printing technology advantage is. In detail, the application of the 3D printing technology means creating a new way of the medical treatment. At the beginning of 2010, when American researchers successfully printed an organ, it seems that to directly print the human body is not impossible (Hsu, 2013). It is more similar to the cloning technology. Patients will not reject organs that are printed out from 3D printers. It can also print hands, teeth, hearing aids and so on. People have to admit that the power of technology is great and cannot be ignored. In the future, 3D printers probably will do anything for people, for the entire society or for the earth. People just need to offer an idea, some of the material, and a 3D printer. Then every idea will become a reality. Moreover, in medical term, 3D printing technology will introduce a new concept of human implantation, medical treatment, or organ substitutes. The future of 3D printing definitely will be promising.
