Material restrictions
Although high-end industrial printing can achieve plastic, some metal or ceramic printing, but can not be printed material is more expensive and scarce. In addition, the printer has not reached the level of maturity, can not support the daily life of a variety of materials exposed.
Researchers have made some progress in multi-material printing, but unless these developments are mature and effective, materials will still be a major barrier to 3D printing.
Machine restrictions
3D printing technology has gained some level of rebuilt geometry and performance and almost any static shape can be printed, but moving objects and their sharpness are hard to come by. This difficulty may be solved for the manufacturer, but 3D printing technology to enter the ordinary family, everyone is free to print what you want, then the machine's limitations must be solved.
Intellectual property worries
In the past few decades, the intellectual property rights in the music, film and television industries have become more and more important. 3D printing technology can also address this issue, because much of what is in reality can be more widely disseminated. People are free to copy anything and they are not limited in number. How to formulate 3D printing laws and regulations to protect intellectual property rights, but also one of the problems we face, or there will be flooding phenomenon.
Moral challenge
Morality is the bottom line. It is hard to define what kind of things will violate the moral rules. If some people print biological organs and living tissues, they will encounter great moral challenges in the near future.
Take the burden
3D printing technology to bear the cost is high. The first 3D printer costs 15,000. If you want to reach the general public, price reduction is necessary, but it will cost with the formation of conflict.
Each of these new technologies faces these similar barriers early in their life, but I believe finding a reasonable solution will result in a faster development of 3D printing technologies, just as with any rendering software, to keep it up-to-date.
3D printing technology can not be applied to mass production, so some experts advocate 3D printing is the third industrial revolution, this argument is just a gimmick. Foxconn has been producing iPhones for Apple for years. Terry Gou to 3D print mobile phone manufacturing, for example, that 3D printing products can only see can not be used, because these products can not add electronic components, can not be mass production of electronic products. Even if 3D printing does not produce electronic products, but limited by the material, there are few other products that can be produced. "Even the products that are produced can not be mass-produced.
"3D printing is indeed more suitable for small-scale manufacturing, especially high-end customized products, such as automotive parts.Although the main material is plastic, the future of metal materials will certainly be applied to 3D printing," said Klump said , 3D printing technology has entered the dentist, jewelry, medical industry, the scope of the future can be applied more and more widely. At the end of November 2014, 3D printing technology was named by Time magazine as one of the 25 best inventions of the year 2014. For consumers and businesses, this is a boon. In the past year alone, high school students 3D printed rail cars for physical class experiments, scientists 3D printed human organ tissue, and General Electric used 3D printing to improve the efficiency of its jet engine. American 3D Systems' 3D printers are capable of printing candies and musical instruments, said Avi Reichenhall, chief executive of the company. "It's really a technology that works for nothing."
