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 printing process 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 liquid resin 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.
