Two Royal College of Art graduates have unveiled a method of reusing nylon 3D printing waste, which can be used to create items such as furniture.
Reuters reports that Seongil Choi and Fabio Hendry have developed a way to reuse discarded nylon from selective laser sintering (SLS). The powdered nylon is mixed with silica sand, with this composite material placed in a box that also contains wire made of ni-chrome.
The pair tried different types of reclaimed plastic to use in the process. They have called their invention “hot wire extensions”.
“Soon we discovered that SLS 3D printing produces a lot of waste,” explained Choi.
The wire has between 10 and 120 volts run through it and heats to 500 degrees Celsius. This happens for 20 minutes and the material around it solidifies into a predetermined shape, according to Choi.
Choi and Hendry's company said there was a possibility of scaling the process for use on an industrial scale.
