DMLS machines produce high-resolution objects with desirable surface features and required mechanical properties. The layers adhere through temperature control or chemical bonding agents. Additive manufacturing, also known as 3D printing, is a process used to create a physical (or 3D) object by layering materials one by one based on a digital model. Additive manufacturing allows the creation of lighter, more complex designs that are too difficult or too expensive to build using traditional dies, molds, milling and machining. The Aerospace industry is a pioneering sector for additive manufacturing and is paving the way to serial production. For example, aluminum alloys are used to produce exhaust pipes and pump parts, and polymers are used to produce bumpers. Leading oral implantologist, researcher and inventor Prof. Dr. Mario Kern is launching his Extended Anatomic Platform at the IDS show this month. The term “additive manufacturing” references technologies that grow three-dimensional objects one superfine layer at a time. A process called photopolymerization cures each microfine resin layer using ultraviolet (UV) light precisely directed by mirrors. Now, AM can bring digital flexibility and efficiency to manufacturing operations. GE Additive specializes in developing Powder Bed Fusion (PBF) machines for the additive manufacturing of metal parts. Similar to standard 3D printing, AM allows for the creation of bespoke parts with complex geometries and little wastage. Unlike traditional forms of manufacturing, this process is not subtractive—in which material is removed—nor does it require molding or casting. In the auto industry, AM's rapid prototyping potential garners serious interest as production parts are appearing. Biochemical healthcare applications include the use of hardened material from silicon, calcium phosphate and zinc to support bone structures as new bone growth occurs. That is, rather than subtract material such as is often seen in traditional means of production — think CNC milling, cutting, carving — additive manufacturing adds material to build a shape. TWI has been developing LMD technology for the last ten years. To … Within DMLS, a laser sinters each layer of metal powder so that the metal particles adhere to one another. The basics in Additive Manufacturing is rather than taking material away, it adds to it instead. Additive manufacturing (AM) or additive layer manufacturing (ALM) is the industrial production name for 3D printing, a computer controlled process that creates three dimensional objects by depositing materials, usually in layers. The Ultrasonic Additive Manufacturing process uses sheets or ribbons of metal, which are bound together using ultrasonic welding. When compared to the relative tedium of traditional prototyping, AM offers a more dynamic, design-driven process. While additive manufacturing seems new to many, it has actually been around for several decades. Computer-aided-design software or 3D object scanners are used to create models to direct the hardware. A variety of ceramics have also been used in additive manufacturing, including zirconia, alumina and tricalcium phosphate. With SLS, a laser sinters thermoplastic powders to cause particles to adhere to one another. As its name implies, additive manufacturing adds material to create an object. There are number of distinct AM processes with their own standards, which include: This technique uses a 3d printing style head moving on x, y and z axes to deposit alternating layers of powdered material and a liquid binder as an adhesive.
