Taking additive manufacturing’s heart beat

Additive manufacturing, or 3D printing, builds objects by adding layers and it is emerging as a more flexible and reliable way of manufacturing complex structures in the aerospace, engineering and biomedical industries. A British team is at the ESRF’s ID19 to see into the heart of the process and understand it.

“I would not want to ship this equipment on an aeroplane”, Chu Lun Alex Leung said, scientist from the University of Manchester. “It was too precious to leave it in the hands of third parties”, he added. Instead of coming to the ESRF by aeroplane, Leung and his colleagues endured the 12-hour drive in a rental van all the way from Oxfordshire (UK) to the ESRF to make sure their unique equipment arrived safely.

Leung was referring to the laser additive manufacturing (LAM) process replicator, or LAMPR for short, a machine himself and colleagues at the Research Complex at Harwell have developed that 3D prints polymers, metals and ceramics while ESRF’s X-rays probe the heart of the process – the melting and solidification of powders to form complex 3D printed components.
