3D printing technology is a modern manufacturing technology, it has a wide range of application prospects, including medical, construction, education and other fields. The Chinese government attaches great importance to scientific and technological innovation, and at the same time strictly regulates and regulates the use of 3D printing technology to ensure its development within the framework of law and safety. Chinese laws and regulations clearly stipulate that it is strictly forbidden for anyone to manufacture, distribute or use illegal weapons, including weapons manufactured using 3D printing technology. China's public security organs and international cooperation agencies will also continue to strengthen the monitoring and suppression of such acts to ensure the safety of people's lives and property and social stability. We call on the majority of the people to consciously abide by national laws and regulations and jointly maintain a harmonious and stable social environment.
