Use of Gold Helps in Detecting Faults in 3D Printed Products

Technological transitions are now being adopted in various business. 3D printing is one of the technology that is largely changing the primitive ways of manufacturing. Due to minute specification in 3D printed products, it becomes difficult to detect the defects in any product. Therefore, in a combined research conducted by civil and environmental, chemical, bimolecular, and engineering graduates from the Vanderbilt and Fisk University, Nashville has developed a technique in which gold is used to detect defects inside 3D printed products parts. It is done in order to inspect and detect defects that are not visible through naked eyes. This can be done by using optical properties of embedded gold nanoparticles.

The products made with the help of 3D printing has increased the demand and are being widely preferred among large population. 3D printing covers the wide range from consumer products to automobiles and homes. Some problems occurred while making 3D printed materials, such as missing print layers or parts. Due to which these defects can weaken the structure and bring failure to the integrity of the 3D printed products, said the professor of bimolecular engineering, Kane Jenning.

The gold nanoparticles are mixed with dissolved plastic polymer, which is further used for 3D printing after it gets dried and hardened. In this process the researchers are using absorbance properties of the embedded gold nanoparticles. It helps in detecting faults in the areas where the absorbance decreases and the defect is found with one single nondestructive measurement.  This process is very quick and simple as compared to large sensing systems as they have sensor all over the parts.
