3D Printed Bridges

In Spain, the first pedestrian bridge printed in 3D in the world (3DBRIDGE) was inaugurated 14th of December of 2016 in the urban park of Castilla-La Mancha in Alcobendas, Madrid. The 3DBUILD technology used was developed by ACCIONA, who was in charge of the structural design, material development and manufacturing of 3D printed elements. The bridge has a total length of 12 meters and a width of 1.75 meters and is printed in micro-reinforced concrete. Architectural design was done by Institute of Advanced Architecture of Catalonia (IAAC). The 3D printer used to build the footbridge was manufactured by D-Shape. The 3D printed bridge reflects the complexities of nature’s forms and was developed through parametric design and computational design, which allows to optimize the distribution of materials and allows to maximize the structural performance, being able to dispose the material only where it is needed, with total freedom of forms. The 3D printed footbridge of Alcobendas represented a milestone for the construction sector at international level, as large scale 3D printing technology has been applied in this project for the first time in the field of civil engineering in a public space. x Apple In-Ear Headphones Apple In-Ear Headphones (introduced on September 9, 2008, revised on September 12, 2012) are only sold independently. Like the regular earbuds they have a remote control and microphone built-in. They are made available as the high-end earbud offering with dual drivers, advertised as "engineered for superior acoustic accuracy, balance, and clarity". The remote and protective case was redesigned on September 12, 2012, with the remote now matching that of the EarPods and the case subsequently modified with elements of the EarPods case while retaining the triangular shape.
