The rise of 3D printing industry and its advantages and disadvantages application

in recent years, you may often hear the word 3D printing technology, because this technology * is very hot. At the Microsoft build2013 developer conference, Microsoft officially launched the windows8.1 preview operating system. This * new version of windows8 system is upgraded with 3D printing function, which gives more meaning to the print buttons in the system. Under this trend, we should treat the fire of 3D printing technology rationally

the rise of 3D printing

in fact, 3D printing is not a new technology, but a technology that appeared in scientific research institutes many years ago. Based on digital model files, it uses powder metal or plastic and other bindable materials to construct objects by printing layer by layer. It is a means to print the drawing out of the model by connecting a computer with a 3D printer

3d printing advantages

3d printing has the following advantages over traditional manufacturing: high speed. One time completion rather than step-by-step optimization, the product shape has a larger imagination space, and the shape that is not convenient for traditional manufacturing can be made by software. In addition, the modification cost is small, and the new version can be produced quickly only by modifying some parameters in the software

disadvantages of 3D printing

3D printing can meet the requirements for components with low general requirements and weak professionalism, but 3D printing is obviously inadequate for products with high hardness

firstly, the material performance is poor, and the strength, stiffness and machinability are far inferior to the traditional processing methods

the second is the limitation of materials and high cost. At present, the materials used for 3D printers are very limited, mainly gypsum, inorganic powder, photosensitive resin, plastic, etc. 3D printing products are very fragile and can't stand tossing

again, there is a problem of accuracy. Due to the step effect in layered manufacturing, although each layer is very thin, it will still form a step with a certain thickness under a certain micro scale. If the object surface to be manufactured is circular arc, it will cause accuracy deviation

application of 3D printing

at present, 3D printing is mainly used in traditional manufacturing, medical industry, cultural relics protection industry, architectural design industry and accessories and ornaments industry, and has been widely used in these industries. In the medical industry, 3D printing can also tailor organs for organ transplant patients. Of course, printing human organs requires special polymer materials to avoid human exclusion

3d printing comments

recently, Hon Hai Chairman Terry Gou expressed his views on 3D printing technology. Terry Gou said that this technology can not be widely used for commercial purposes. For example, 3D printing can be made, but it can only be seen but not used; 3D printing products cannot be added to electronic components, and mass production of electronic products cannot be formed. 3D printing is by no means the third industrial revolution, just a gimmick. If it can really subvert the industry, my Guo character is written upside down. We can only test the correctness of chairman Guo's bluster through time

five trends of 3D printing

from the price point of view, industrial 3D printers have high costs, often as high as millions of yuan. They are mainly used in high-end manufacturing fields such as modern industry and biomedicine, while desktop 3D printers for household consumption sell for more than 20000 yuan. They are more high-end toys for high-income families, printing some plastic gadgets, and their popularity is limited

it can also be seen from the market scale that 3D technology was born as early as the 1980s. However, until 2013, the global 3D printing market was only nearly $4billion, which is not as big as the annual output value of a large enterprise. According to the statistics of the world 3D printing technology industry alliance, the Chinese market is about US $300million, the European market is about US $1billion, and the US market is about US $1.5 billion

according to the statistics of the total number of patent applications in this industry in the past 30 years, we can see that a large number of innovative products and technologies have emerged in the 3D printing industry in the past three years, which has exceeded the sum of innovations in this industry in the past 20 years. With the decline of prices, more and more people began to use 3D printing technology, and more innovators entered the market, constantly pushing prices down. The next five years will see the 3D printing market continue to develop along the index curve. In the next five years, the following five landmark events are likely to occur in the field of 3D printing:

first, 3D printing can create human organs

organovo claims that they will use 3D technology to print out human liver this year. However, the liver in Organovo's statement is still far from the fully functional human liver that many people began to imagine. However, in terms of current technology research and development status, 3D printing of this fully functional human liver will be realized in recent years. It is understood that researchers have been able to print out dozens of different biological cells. The biomedical field in 2019 will undergo earth shaking changes due to the rapid development of science and technology in China

II. Giants enter the 3D printing market

HP and Epson have stated that they want to enter the 3D printer market. However, there are still many giants such as Google, Microsoft and even apple that have not yet entered the market. If the consumer 3D printer market continues to grow, Apple may develop a relatively cheap and reliable 3D printer. Microsoft or Google will cut into this industry from the perspective of software or information. Amazon may acquire a company like shapeways to provide users with 3D printing services and send the printed things to their doorstep. In the coming year, we will see major mergers and acquisitions in the industry. And in five years, we will see some new faces appear

III. most metal laser sintering 3D printers will be reduced in price.

this year and next, relevant patents will continue to expire, and we will see a new innovation explosion. As has happened in the plastic printing market, crowdfunding projects and higher quality metal printing products and technologies provided by new and old companies will drive the whole market forward significantly. It is reported that the price of fdm3d printer fell from tens of thousands of dollars to less than 500 dollars in a few years. The same thing will happen to higher quality laser sintered 3D printers based on metal materials

IV. 3D printing guns will trigger crimes

at present, 3D printing technology has reached the point where guns can be printed. Although plastic is used to make usable guns, it is still prospective industry research institute 3 - elastic recovery depth after removing the main experimental force F1; Guoxueli, a researcher of new energy, said it was difficult. But the diffusion of metal based 3D printing technology will change all this. It is difficult for the government to impose rules on who can not use these new high-quality 3D printers and check what files they have downloaded from the Internet. Subsequently, when a 3D printing gun is exposed in a major crime, you will know that we have entered a new era, which will require new and comprehensive laws to deal with all this

v. every school in the United States will have 3D printers, and the ownership rate of Home 3D printers has reached 40%

the utilization rate of 3D printers in the field of education is rising. Makerbot has launched an initiative to extend their 3D printers to every school in the United States. With the decline of 3D printer price and more applications in learning, 3D printer will become the main auxiliary tool in almost every course from grade 3 to grade 12 (equivalent to grade 3 to grade 3 in China). For students, 3D printers can turn their fantasies into reality. They are a very powerful tool to cultivate students' creativity and learning ability


in this era of global hot 3D printing aimed at reducing or eliminating the release of volatile organic compounds (VOCs), we need to look at this technology rationally. Although it can bring better development opportunities for Chinese enterprises, we can not ignore the challenges faced by 3D printing technology
