What is AM? It uses a cross-hatch method during the printing process so the completed part is easy to remove. This resin hardens on exposure to UV light. The binder drops the binder as per the geometry of the object to be built. Additive manufacturing is achieved using an additive process, where successive layers of material are laid down in different shapes. This additive manufacturing technology is used for building parts with high dimensional accuracy and smooth surface finish. Selecting the most suitable Additive Manufacturing (AM) process for a particular application can be difficult. However, to standardise the industry, the ASTM group “ASTM F42 – Additive Manufacturing”, in 2010, classified the gamut of Additive Manufacturing technology into 7 types. This is an overview of additive manufacturing (3D printing). In DED, a nozzle holds a material in a wire form which is known as a feed which moves across multiple axis and an electron beam projector which melts the feed as it moves across while tracing the object geometry. A simple example of the type of restrictions that additive manufacturing suffers from is the inability to manufacture entirely enclosed hollow volumes. There are a number of different technologies used in the metal Additive Manufacturing systems available today. But scale will arrive in the next few years. This great variety of metal and alloys means that it’s possible to select the perfect material for the design, fulfilling criteria such as core strength and also cost. The Sheet Lamination process includes two types of manufacturing techniques, Ultrasonic Additive Manufacturing (UAM) and Laminated Object Manufacturing (LOM).
