  According to EDN Taiwan's report on July 12, 2018, 3D printing has gradually improved, but as a successful future manufacturing process, there are still obstacles to overcome. US researchers have conducted the following tests on the high cost of 3D printing and the characteristics of multiple reciprocating layers.

  1. High-cost of 3D printers: Researchers at Carnegie Mellon University have developed an injection-based bio-printing mechanism that integrates into any 3D printer for under US$500.

  2. Multiple reciprocating layer 3D printing of objects: The researchers tested different materials and finally used polymer filaments as an "exoskeleton" to improve the strength of the 3D printed structure. Their paper "Enhanced Impact Resistance of Three-Dimensional- Printed Parts with Structured Filaments", is published in the journal “ACS Applied Materials and Interfaces”. 

  Further research on new materials and processing techniques is bound to produce significant improvements in 3D printing. Although there are still some obstacles to overcome in terms of attenuation factors such as strength, resistance, heat and impact, the technology has made significant progress. In the near future, a wide variety of objects will all be made by 3D printers.
