An effective rule for translating optimal selective laser melting processing parameters from one material to another

Eric Boillat, Jamasp Jhabvala, Rita Drissi Daoudi, Roland Logé, Hossein Ghasemi Tabasi, Toni Ivas

Selective Laser Melting (SLM) or Laser Powder Bed Fusion (L-PBF) is the most studied laser-based additive manufacturing process for metals and alloys. One important issue in SLM is the time-consuming identification of a process window leading to quasi full ...

Healing cracks in selective laser melting by 3D laser shock peening

Jamasp Jhabvala, Andreas Burn, Christian Leinenbach, Roland Logé, Nikola Kalentics, Hossein Ghasemi Tabasi, Navid Sohrabi

Selective Laser Melting (SLM) of Ni-based superalloys such as CM247LC is prone to weld-cracking. This paper investigates how to suppress cracks by repeatedly applying Laser Shock Peening (LSP) during the building phase of SLM. Samples made of CM247LC were ...

The role of nanocrystalline binder metallic coating into WC after additive manufacturing

Eric Boillat, Jamasp Jhabvala

Tungsten carbide with microsized particle powders are commonly used embedded in a tough binder metal. The application of these composites is not limited to cutting tools, WC based material has been increasingly used in gaskets and other mechanical parts wi ...

3D Laser Shock Peening – A new method for the 3D control of residual stresses in Selective Laser Melting

Eric Boillat, Jamasp Jhabvala, Christian Leinenbach, Roland Logé, Nikola Kalentics

This paper describes a hybrid additive manufacturing process – 3D Laser Shock Peening (3D LSP), based on the integration of Laser Shock Peening (LSP) with selective laser melting (SLM). The well-known tensile residual stresses (TRS) in the as – built (AB) ...

An innovative method to build support structures with a pulsed laser in the selective laser melting process

Eric Boillat, Rémy Glardon, Jamasp Jhabvala, Cédric André

In selective laser melting machines, continuous laser are usually used to melt the powder. The support structures, which are inevitable when dealing with elaborated pieces, necessitate a complex design by CAD in order to be easily removed. This paper propo ...

Study of the consolidation process under macro- and microscopic thermal effects in selective laser sintering and selective laser melting

Jamasp Jhabvala

Selective Laser Sintering (SLS) and Selective Laser Melting (SLM) are parent Additive Manufacturing processes using a laser to solidify metallic, ceramic, polymer or composite powders. During the process, the object is built layer by layer. A laser source ...
