Jen Kinney for Next City: Alcobendas, Spain, this week unveiled a 3D-printed pedestrian bridge, reports 3ders.org, a 3D printing news site. The approximately 40-foot concrete bridge is made up of eight separate parts that fit together, and was created using an additive manufacturing process. It spans a small canal in Castilla La Mancha Park.

According to a statement from the Alcobendas City Council, the 3D printing process resulted in far less waste than normally produced while creating concrete structures, making it less expensive than traditional processes.

Large-scale 3D printing holds the promise of versatility — since structural elements can be created without molds or forms — and of sustainability, since raw material can often be recycled and fewer resources are required during manufacture. Cont'd...

Cold air to -50°F (-46°C) from your compressed air supply - with no moving parts!

A low cost, reliable, maintenance free solution to a variety of industrial spot cooling problems. Using an ordinary supply of compressed air as a power source, vortex tubes create two streams of air, one hot and one cold, with no moving parts. Vortex tubes can produce: • Temperatures from -50° to +260°F (-46° to +127°C) • Flow rates from 1 to 150 SCFM (28 to 4248 SLPM) • Refrigeration up to 10,200 Btu/hr. (2571 Kcal/hr.) Temperatures, flows and refrigeration are adjustable over a wide range using the control valve on the hot end exhaust. EXAIR Vortex Tubes are constructed of stainless steel. The wear resistance of stainless steel, as well as its resistance to corrosion and oxidation, assures that EXAIR Vortex Tubes will provide years of reliable, maintenance-free operation. https://exair.co/184_530
