New Balance joins 3D printing brigade with customised spikes
14/03/2013
The process uses race-simulation biomechanical data which the US company’s research lab collects using a force plate, in-shoe sensors and a motion capture system. Advanced algorithms and software are then applied to translate the data into 3D printed spike designs. It then uses selective laser sintering (SLS) to convert powder materials into solid cross-sections, layer by layer using a laser.
"Utilising our Team New Balance athletes to develop the customisation process was extremely helpful,” said Sean Murphy, New Balance's senior manager of innovation and engineering.
Jack Bolas, a 1500 metre runner, in January became the first track athlete to compete in customised 3D printed plates, according to the company.
In addition to printing semi-rigid parts like spike plates for track runners, New Balance is working on softer SLS printed components that mimic the cushioning properties of foam midsoles, which should bring the customisation process to a wider customer base.
New Balance CEO Robert DeMartini said: "We believe this is the future of performance footwear and we are excited to bring this to consumers. We are the only major athletic brand to manufacture shoes in the US, and developing our printing capabilities could ultimately help us by adding highly technical positions to our already skilled labour force in Massachusetts and Maine."
