A 2D lattice Boltzmann model is developed to investigate melting and re-solidification of a
randomly packed powder bed under the irradiation of a Gaussian beam during selective beam …

Powder bed fusion processes are additive manufacturing technologies that are expected to
induce the third industrial revolution. Components are built up layer by layer in a powder bed …

During powder based additive manufacturing processes, a component is realized layer
upon layer by the selective melting of powder layers with a laser or an electron beam. The …

Selective electron beam melting (SEBM) was successfully used to fabricate novel cellular Ti–6Al–4V
structures for orthopaedic applications. Micro computer tomography (μCT) analysis …

Additive manufacturing by selective electron beam melting is a promising way to fabricate
complex Ti–6Al–4V components. Sound parts can be realized by applying quite different …

We present a 2D- and 3D-lattice Boltzmann model for the treatment of free surface flows
including gas diffusion. Interface advection and related boundary conditions are based on the …

Cellular titanium combines the excellent properties of compact titanium with the extraordinary
properties of cellular structures. The production of cellular titanium based on standard …

Considerable progress has been made recently in the production of metallic foams. Scale
up has progressed so far that widespread commercial use may become a reality in the near …

In the present paper a broad parameter window for processing Ti–48Al–2Cr–2Nb by selective
electron beam melting is investigated. Data for the aluminium loss during the process in …

Highly porous titanium structures are widely used for maxillofacial and orthopedic surgery
because of their excellent mechanical properties similar to those of human bone and their …
