The New Balance Zante Generate is the first 3D-printed running sneaker to be made commercially available, however there will only be forty-four pairs sold. The limited edition release is a tribute to the company's owner Jim Davis and his forty-fourth year owning the Boston-based shoe company. While the upper half of the Zante Generate is made using traditional materials like an engineered mesh, the midsole is entirely 3D printed using a selective laser sintering process. The sole is printed using 3D Systems DuraForm TPU Elastomer material which results in a highly flexible, but durable part.
