The Chinese have increased the speed of 3D printing thousands of times (3 photos)


The introduction of 3D printing technology can significantlyinfluence the development of modern industry, construction, medicine and life. The main problem of modern devices for 3D printing is the low speed of creating objects. To solve this problem, with a parallel significant reduction in the cost of production of new products will help technology proposed by Chinese developers, accelerating the process by almost 10 thousand times, while increasing printing accuracy.


The new technique uses high-precision 3D printing in the manufacturing process for biomedicine products. The technology was developed at the Department of Engineering and Automation of the Chinese University of Hong Kong.

Scientists have proposed using technologyfemtosecond projection of two-photon lithography (FP-TPL). The use of temporary focusing when controlling the laser spectrum made it possible to print layer by layer, layer by layer, and not by sequential dot printing.


As a result, researchers were able to reduce timeprinting by creating whole layers, for the same time that was previously required to create a single point. As a result, the accuracy of the created objects also increased. 3D printing speed increases in the range from 1000 to 10,000 times. Reducing the operating time of the laser will also affect the reduction in the cost of production, as the life of the laser system is increasing. According to the developers, the price of 3D printing should be reduced by 98%.
