‘You can 3D print one material through another, as if it were invisible’: New 3D printing technique

Posted by in categories: 3D printing, materials

Scientists have developed an advanced technique for 3D printing that is set to revolutionize the manufacturing industry.

The group, led by Dr. Jose Marques-Hueso from the Institute of Sensors, Signals & Systems at Heriot-Watt University in Edinburgh, has created a new method of 3D printing that uses near-infrared (NIR) light to create complex structures containing multiple materials and colors.

They achieved this by modifying a well-established 3D known as stereolithography to push the boundaries of multi-material integration. A conventional 3D printer would normally apply a blue or UV laser to a that is then selectively solidified, layer by layer, to build a desired object. But a major drawback of this approach has been the limitations in intermixing materials.
