Advances in wire-based additive manufacturing (AM) technology have created new opportunities for prototyping, legacy part production, and aerospace tooling. As residual stress can often lead to deformations in a component, cooling must be factored into the process. 0000007533 00000 n 0000110034 00000 n Airbus, PAG, and BIAS. 0000011620 00000 n 0000114195 00000 n 0000111991 00000 n 0000008395 00000 n Welding in process with view of robotic welder. This allows for the production of larger parts, which wouldn’t be possible with PBF processes. High deposition rates, low material and equipment costs, and good structural integrity make Wire & Arc Additive Manufacturing a suitable candidate for replacing the current method of manufacturing from solid billets or large forgings, especially with regards to low and medium complexity parts. This guide will focus on how WAAM works, its benefits and limitations, as well as key WAAM companies and successful applications. 0000018906 00000 n AML3D’s Managing Director, Andrew Sales, studied at Cranfield and, fascinated by the technology’s potential, founded a WAAM service bureau in Australia in 2014. To reduce its buy-to-fly ratio (the ratio of material inputs to final part output), this company turned to wire arc additive manufacturing to create near-net shape parts. WAAM hardware usually includes off-the-shelf welding equipment, which is less expensive than many metal 3D printers available on the market. Such long lead time items must be held in a physical inventory or replaced prematurely. Introduction Additive manufacturing (AM), also known as rapid forming technology, was proposed by Charles W.

As the wire feedstock is a 100 per cent dense input material, there is negligible porosity induced in the fabrication process, leading to a very dense final part. [1] It is typically a near-net-shape process where a part is overbuilt then machined down to the final shape. Directed Energy Deposition (DED) is a category of metal additive manufacturing (AM) that utilizes robotic welding processes to print at high deposition rates but with relatively low resolution. Additive Manufacturing Methods Two of the main Additive Manufacturing avenues available to fabricate parts with high toughness in the bulk and high wear resistance near the surface are 3D Printing and Laser Direct Metal Deposition. 0000114411 00000 n For this reason, additive manufacturing should be considered as a potential means of production for Invar parts in the future. December 07, 2020 ... (AM) solution and its underlying Wire Arc Manufacturing (WAM) technology is slated to offer iKAD flexible configuration. Any metal that can be welded can also be used with WAAM. Unlike PBF AM machines, which have a limited build envelope, the robotic arm of a WAAM machine has more freedom of movement, meaning that the size of a component isn’t limited by space, but only by the distance the robotic arm can reach. You can see the process in action here: WAAM can work with a wide range of metals, provided they are in wire form. This process increases the total lead time up to six to eight weeks. 0000006649 00000 n Home » Additive » Wire Arc Additive Manufacturing. [Image credit: MX3D]. About WAAM; ... Gefertec’s bespoke software acts as the interface between the planning data and the arc-welding machine by taking the CAD data and converting it into individual digital printing layers – the CAM model. 0000150011 00000 n Additionally, wire is typically easier to handle than powder, which requires specialised protective equipment to use.

Gefertec’s 3D printer was used to produce this spare part, and the project, from the initial design to reverse engineering and production, was completed within two months. This means that the process has to take place in an inert gas chamber. Prior to welding of titanium, widely practiced in the aerospace Industry, the oxygen content of the purge gas must be reduced to a level below 50 ppm. WAAM is a variation of a Direct Energy Deposition technology and uses an arc welding process to 3D print metal parts.
