Metelled – METal Evolved by Linear LasEr Deposition

梅泰德公司在添加剂制造(AM)方面设想了一种新的方法，既创造了新的开发战略，又创造了就业机会。它可以提供一种新的途径来实现金属AM技术提供的适用性和多样性。新的更大规模的沉积，具有微观特征，优化的能量管理和低成本的生产将成为可能。金属化项目使用原子层沉积来构建3D结构。快速沉积过程被用于生产其他行业的千吨高纯金属。低温加工是可能的，因为金属没有熔化，因此残余应力最小，夹杂物和气孔被消除。金属化工艺消耗的原料是块状金属而不是粉末。所有部件都可以在设备内回收，不需要或排放昂贵的屏蔽气。这项可行性研究构建了一个沉积池来研究激光对通过玻璃进行线性沉积的影响。之所以出现这种创新，是因为该工艺是：*从原始矿石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。*腔体建造体积可以很大。*低残余应力可能会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。*原料的快速更换提供了一种即插即用的方法。*从原子级沉积获得高分辨率。*也可以进行大面积沉积。*均匀的X、Y、Z强度。*快速高度沉积。

"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."
