Footwear, Shoes and Boots Design Architech Footwear by Alan B. Guyan This is the first 3D Printed training shoe to be sold to the consumer market. After, two years of researching various organic shapes and structures to create a truly unique and functional 3D Printed lattice design. This training shoe provides dynamic stability, and also has a luring design appeal. These interconnecting lattice beams can only be manufactured by 3D Printing, and could never be replicated by conventional molding processes. This upper design uses a 3D Auxetic pattern, which can stretch and adapt to the foot shape.
