Metelled – METal Evolved by Linear LasEr Deposition

“mettelled设想了一种增材制造（AM）的新方法，创造了新的开发策略和就业机会。它可以为金属增材制造技术提供的适用性和多样性提供新的途径。新的更大规模的沉积，具有微观特征，最佳的能源管理和低成本的生产将可能使用该工艺。Metelled项目使用原子层沉积来构建3D结构。在其他行业，快速沉积工艺被用于生产千吨高纯度金属。低温加工是可能的，因为没有金属熔化，因此残余应力被最小化，夹杂物和孔隙被消除。金属化工艺消耗的原料是金属块而不是粉末。所有组件都可以在设备内回收，不需要昂贵的保护气体或排放。本可行性研究构建了一个沉积池来研究激光对玻璃线性沉积的影响。这一创新的出现是因为该过程是：*从原料矿石中生产金属部件的最低能量方法。*沉积过程是低能量和低温的。*室构建体积可以很大。*低残余应力可消除后处理成本和能源。*使用易于处理的块状原料代替粉末。*快速改变原料提供了即插即用的方法。*精细的分辨率，从原子水平沉积。*大面积沉积也是可能的。*均匀的X， Y， Z强度。*快速z高度沉积。”

"Metelled conceives a new method in additive manufacturing (AM) creating both new exploitation strategies and employment opportunities. It could offer a new avenue to the applicability and diversity that metal AM technology offers. New larger scale deposition, with micro features, optimal energy management and low cost production will be possible using the process.The Metelled project uses atomic layer deposition to construct 3D structures. The rapid deposition process is used to produce kilo tonnes of high purity metals in other industries. Low temperature processing is possible because there is no melting of metal, therefore residual stresses are minimised, inclusions and porosity are eliminated.The Metelled process consumes feedstock is lump metal instead of powders. All the components can be recycled within the equipment, and no expensive shielding gases are required or vented. This feasibility study constructs a deposition cell to study laser effects on linear deposition through glass.The innovation arises because the process is:* The lowest energy method to produce a metallic part from a raw ore.* The deposition process is low energy and low temperature.* Chamber build volumes can be large.* Low residual stress may eliminate post-processing costs and energy.* Easy to handle lump feedstock is used instead of powders.* Quick change of feedstocks gives a plug-and-play approach.* Fine resolution, from atomic level deposition.* Wide area deposition also possible.* Homogeneous X, Y, Z strength.* Rapid z height deposition."
