Laser metal deposition (LMD) is getting more attention as a 3D printing technique recently. Compared to the cladding application, process of building structures challenging control when it comes complex structures. Changing heat transfer mechanisms over height and at critical part geometries can lead instabilities during process. This paper studies effect surface temperature on single track geometry formation LMD The geometrical characteristic key factor that needs be controlled monitored in...
Additively manufactured components made of metallic material are subject to special consideration for many R&D departments, since the process control is not yet sufficiently reliable and therefore an extensive quality assurance necessary. For this reason, few structural aviation have been established so far. In paper, a feasibility study use laser metal deposition (LMD) additive manufacturing fuselage aluminum carried out. The result parameter set with minimized energy input. However, due...
Scanner-based selective laser deburring (SSLD) is an innovative edge-refinement process. This wear-free process uses a single source for several materials to create defined radii and bevels. The study based on three-stage approach. first stage describes the development with interdependencies between its parameters, burrs in cut sheet-metal parts. Edges are remelted using 5 kW Yb:YAG at wavelength of 1.03 μm scanner system order refined edges radii. Optimized parameters SSLD investigated...
Laser metal deposition (LMD) connected with milling processes offers the opportunity for an efficient, resource conserving manufacturing large structural components made from Ti-6Al-4 V. Conventional routes example in aerospace industry come along up to 95% of waste material that has be machined bulk material. LMD is additive process building parts based on nozzle-fed powder by laser solidification. This technology unique advantages production near net-shape parts. In contrast bed-based...
The additive manufacturing of titanium parts by laser metal deposition (LMD) offers a promising alternative to conventional machining aviation parts. technology enables the production near net shape with higher rates than powder bed-based processes. Ti-6Al-4V is fed directly into high-power beam in order form track on underlying material. For three dimensional several tracks are stacked top each other. In this paper material evolution from solid wall during LMD investigated. Powder...
