Some defects found in parts built using AM are related to processing parameters or to the composition of alloys optimised for more conventional, slow-cooling manufacturing process. These defects – such as porosity or cracking – can sometimes be healed by post-processing such as hot isostatic pressing (HIP). Yet, the formation of pores during AM is also linked to the quality of virgin powder.

Residual stress in metal components built using laser direct deposition

20/11/2015

 
Direct Laser Deposition (DLD) is a type of laser-based additive manufacturing process used to create functional metal components layer by layer using a sliced 3D CAD (computer aided drawing) file. Unlike Selective Laser Melting which utilizes a bed of powder metal that is ‘selectively’ melted via a laser, DLD is based on melting feedstock (blown powder or wire) at the focus point of a laser source. In this post, we address the residual stresses occurring during the build of metal components with DLD technology [1].

Unique applications of Laser Metal Deposition technology

10/7/2015

 
Laser Metal Deposition (LMD) technology (= Direct Metal Deposition DMD) is applied to build near net-shape 3D components [1] with applications covering a broad range of industries. LMD also has some unique capabilities that are absent in the powder bed selective melting and sintering processes. We quickly review here its unique features.
