Journal ArticleDOI
A physical modeling and predictive simulation of the laser cladding process
Florian Wirth,Konrad Wegener +1 more
TL;DR: In this paper, a 3D finite element simulation model of the laser cladding process was developed taking into account heat transfer, fluid flow, surface tension and free surface movement, all input parameters and data are independent of the process parameters but depend only on the material and machine properties, have been obtained from measurements.
Journal ArticleDOI
Selective Laser Sintering and Multi Jet Fusion: process-induced modification of the raw materials and analyses of parts performance
TL;DR: In this article, a comparison of powder and final parts made of commercially available polyamide 12 (PA12) made of commercial polyamide has been carried out, with the results showing that the results obtained through SLS exhibit higher Young's modulus but lower elongation at break and ultimate tensile strength if compared to the ones obtained using multi jet fusion.
Journal ArticleDOI
Laser-structured grinding tools – Generation of prototype patterns and performance evaluation
TL;DR: In this article, a laser ablation with ultrashort pulsed lasers enables high geometrical flexibility and allows for fabrication of micro scale structures in e.g. ultrahard materials that are hardly possible with any other process.
Journal ArticleDOI
Microstructural characteristics of the nickel-based alloy IN738LC and the cobalt-based alloy Mar-M509 produced by selective laser melting
TL;DR: In this paper, the effect of microstructure and the structural anisotropy on the orientation-dependent values of the Young's modulus and the mechanical properties are further discussed.
Journal ArticleDOI
Selective laser melting of an oxide dispersion strengthened (ODS) γ-TiAl alloy towards production of complex structures
Christoph Kenel,Christoph Kenel,Georgia Dasargyri,Thomas Bauer,Thomas Bauer,Alberto Colella,Adriaan B. Spierings,Christian Leinenbach,Konrad Wegener +8 more
TL;DR: In this paper, selective laser melting of oxide dispersion strengthened Ti-45Al-3Nb-Y2O3 with a focus on processing parameters and layer-wise re-scanning strategies is described.
