How large is the market for 3D printing handboard models,which is divided into industrial,medical,and civil grades according to the range of product applications。Among them,the first two levels of 3D printers are very accurate, not only can print plastics and resins, but also can print metal and polymer materials,can produce components needed for aerospace,medical artificial teeth and joints,and even include artificial organs. However,these devices are expensive and cost hundreds of thousands of dollars each,making it difficult to promote them on a large scale。In the civilian market,the precision of 3D printing technology is only millimeters. The materials used are usually plastics and can only be used to make models and toys, or even creative products such as dolls。These 3D printers cost about thousands of dollars and are smaller in size, making them suitable for home use。However, in the future,there will not be some people think of "Equipped with a 3D printer" scenario。A simple analogy is that ordinary 2D printers have been developed for more than 30 years and the price has already fallen to a few hundred dollars,but it has not achieved one。The root cause is that,whether it is 2D or 3D,the printer is still not"just needed,"and people prefer to get a 3D printing service in a professional print shop。The high-end market is small and the low-end market has not yet been formed, which has compressed the imagination of 3D printing. What is even more worrying is that the development speed of 3D printing is not as fast as people think: Take Stratasys as an example。In the third quarter of 2012, the company’s revenue increased by 24% year-on-year,and its growth rate was lower than the second quarter。7 Percentage. Regardless of whether it is an absolute value or a long-term trend,it is difficult for the 3D printing company's performance to make the capital market excited and investors are less confident。
　　However, the focus of 3D printing is not the moment,Its prospects may not necessarily be as pessimistic as the capital market described。Print models, figures and even machine parts cannot fully demonstrate the full potential of this technology; if the cost can be reduced to a reasonable range, 3D printing is expected to become the next “Apollo Project”。In 1961, the United States launched the "Apollo Project" and hoped to send humans to the moon. This project has attracted 20,000 companies, more than 200 universities and more than 80 research institutions,with a total of more than 300,000。Its input/output ratio is as high as 1:14, giving birth to over 3000 high-tech products. After more than 50 years,3D printing is expected to inherit the "Apollo Project" and become a new technology development engine。
