TL;DR: In this article, the mechanical response of Inconel 625 lattice structures fabricated by Selective Laser Melting (SLM) has been investigated and the high ductility of the lattice enables novel insight into the structural mechanics of AM lattice and the associated deformation photography provides a reference for the validation and verification of numerical models of lattice behaviour.

TL;DR: In this article, the authors present an overview of typical process errors and propose a catalog of measures to reduce process breakdowns, based on which a future contribution to quality assurance and process documentation is aspired.

TL;DR: In this article, a new measurement approach by a confocal microscope and three-dimensional surface parameters was proposed to classify different surface orientations and on a special issue in laser sintering: orange peel severity.

TL;DR: This work presents a high resolution imaging system for inspection of LBM systems which can be easily integrated into existing machines and shows that the system can detect topological flaws and is able to inspect the surface quality of built layers.

TL;DR: In this paper, an approach using response surface methodology was chosen to correlate part properties with main influencing factors to predict and to improve part properties based on an enhanced process understanding, and the results showed that part quality, process interruptions, and defective parts can be improved based on the improved process understanding.
