As 3D printing opens more doors for creativity and improving the manufacturing efficiency, it also brings along questions about piracy issues and how intellectual property ownership will be protected, as reported in美国大学知识产权简报.
According to the Swedish online piracy service The Pirate Bay the consumers will download 3D print designs online in a similar manner as they currently download books, movies, programs and music. Some simple CAD designs are already available for download.
WhereThe Pirate Bay’s debate要说3D打印将结束童工并喂养饥饿的童工，版权和专利持有人对发展方向并不那么热情。
传统上，3D打印设计很难复制，但是可能不再是这种情况，因为构建设计的程序和工具已经迅速发展。
The question remains where to draw the boundaries of printing useful everyday objects that don’t violate IPO laws. This could potentially cause major losses for large corporations such as Nike that has been often used as an example in conversations related to the topic.
If looking at the issue geographically, the 3rd人口庞大且腐败较高的世界国家，这确实是一个主要问题，当局对保护版权法的控制权甚至更少。
Right now the current law is still undecided. No matter what, the 3D printing technology will evolve and is not likely to disappear, on the contrary. Perhaps vast decisions are needed to satisfy all parties involved.
