But, in fact, the gear can look very different and still meet those generic requirements. The precise alignment and machining of the rocker arm geometry and a high-quality finish increase durability and reduce friction in the valve mechanism. Since the additive manufacturing process is capable of producing components close to near-net shape, there is often little stock that remains for providing. Additive manufacturing is often used interchangeably with 3D printing and rapid prototyping (even though rapid prototyping can also include other processes). Unlike subtractive manufacturing which creates its final product by cutting away from a block of material, additive manufacturing adds parts to form its final product. The technology is also known as Fused Filament. Additive manufacturing is a layer-by-layer strategy enabling the advanced design and fabrication of complex 3D objects and structures, overcoming geometry limitations and reducing waste production compared to conventional technologies.

Additive Manufacturing: Additive manufacturing processes have minimal material wastage. 25 µm or nominally 10 µin can be defined as having a superfinish. The potential freedom of design offered by AM is, however, often limited when printing complex geometries due to an inability to support. [18] compared the dimensional accuracy and tolerance of three different additive manufacturing processes (LPBF, electron beam melting (EBM), and laser melting deposition (LMD)) using a benchmark demonstrator. If you have a recall or retire an old design, those unusable parts turn to scrap. A commonly cited benefit of additive manufacturing is the ability to consolidate multiple parts into a single one. Updated on: 11 July 2017. Additive manufacturing, commonly known as 3D printing, is an industrial computer-controlled process that produces 3D objects by depositing materials in layers on the base material. Gears and shafts are among them. However, the surface of a component is not always a primary focus. What follows is a two-step process.
