3D printing, often referred to as Additive Manufacturing (AM) is the sequential layering of materials using computers to create three-dimensional shapes. The process appears relatively simple as a 3D digital model of the item is created. This is done either through computer aided design (CAD) or using a 3D scanner.
The printer reads the design and “prints” successive layers of a medium, either liquid, powder, or sheet material. These are joined together or fused to create the final product or item. While the 3d printing process can sometimes be slow, it can create almost any shape which is particularly useful for geometrically complex components.
The future of construction lies with robots getting down and dirty while implementing 3D printing technology. And now, 3D printing has found yet another purpose with the US military building barracks using a large 3D printer. Continue reading →
The future of aviation may be closer than we think thanks to an electric aircraft start-up company, Impossible Aerospace. One of their newly-designed electric drones is capable of flying non-stop for two hours. With $9.4 million in funding from Airbus and two Silicon Valley venture capital firms, electric drones are just the beginning.
Spencer Gore, CEO and founder of Impossible Aerospace, is a former Tesla battery engineer with invaluable industry experience. His vision is to transform aviation using electric drones as proof of concept. The plan is to make longer-range electric passenger aircraft with today’s low energy-density batteries. If all goes according to plan, the future looks bright for zero-emission passenger aircraft. We take a closer look at the technology and the young mastermind behind it all. Continue reading →
Flying cars are once again a hot topic of discussion but this time it involves Metro Skyways, a subsidiary of Israel’s Urban Aeronautics (UA). The company has announced that they are going into the full-scale development of the CityHawk VTOL flying car. The first manned flights of this hybrid-powered six-seater will take place in 2021 followed by full FAA certification. They plan to convert the CityHawk to run on hydrogen fuel cells after the launch.
Urban Aeronautics Ltd has developed advanced aerodynamic technologies that form the basis of a new internal rotor (ducted fan) aircraft known as Fancraft™. They capitalise on their extensive portfolio through two subsidiary companies, Tactical Robotics Ltd and Metro Skyways Ltd. Both companies are developing unique Fancraft™ for specific markets. The CityHawk, wingless flying car with “land anywhere” technology is their latest project and looks impressive, to say the least. Continue reading →
The word “fabrication” means to make something from raw material. Steel fabrication is no different and plays an extremely important role in the world’s infrastructure and economy. Practically every aspect of our civilization benefits from some form of fabricated metal. From household appliances to vehicles and parts, our lives would be unrecognisable without carbon steel, stainless steel and aluminium.
Although the construction of steel buildings dates back to the 20th century, they became more popular during World War II. Thereafter, steel buildings expanded significantly once steel became more readily available. Modern technology, machinery and computer aided design software have pushed steel fabrication to the next level as we see it today. Steel fabrication now involves the implementation of various manufacturing processes including bending, cutting, grinding, brazing and welding. Continue reading →
Several industries currently benefit from aluminium fabrication, which relates to the construction of metal structures by means of cutting, bending and joining. Most extrusions go through some form of further processes such as fabrication, machining and surface treatment. The properties of aluminium make extrusions highly suitable for almost any type of fabrication.
Although fabrication can be applied to any metal, aluminium is considered one of the most common. As a result, there is a big demand for aluminium fabrication services all over the world. If you look at your home or office building, aluminium is all around us. Some of the most common features are aluminium gates and aluminium frameworks used for doors, windows and showers.
