TL;DR: Additive manufacturing implies layer by layer shaping and consolidation of powder feedstock to arbitrary configurations, normally using a computer controlled laser as discussed by the authors, which is based on a novel materials incremental manufacturing philosophy.
Abstract: Unlike conventional materials removal methods, additive manufacturing (AM) is based on a novel materials incremental manufacturing philosophy. Additive manufacturing implies layer by layer shaping and consolidation of powder feedstock to arbitrary configurations, normally using a computer controlled laser. The current development focus of AM is to produce complex shaped functional metallic components, including metals, alloys and metal matrix composites (MMCs), to meet demanding requirements from aerospace, defence, automotive and biomedical industries. Laser sintering (LS), laser melting (LM) and laser metal deposition (LMD) are presently regarded as the three most versatile AM processes. Laser based AM processes generally have a complex non-equilibrium physical and chemical metallurgical nature, which is material and process dependent. The influence of material characteristics and processing conditions on metallurgical mechanisms and resultant microstructural and mechanical properties of AM proc...

TL;DR: The most common additive manufacturing method is called Selective Laser Melting (SLM), developed at the Fraunhofer Institute for Laser Technology ILT as mentioned in this paper, and it has been shown that it provides great potential to fulfill these challenges.
Abstract: Manufacturing enterprises in highwage countries such as Germany are increasingly being exposed to global competition. These enterprises are confronted by an increasing demand for individualized, high quality as well as low-cost products [1]. Additive manufacturing methods have accelerated their technological capability in the last few years and provide great potential to fulfill these challenges. The most common additive manufacturing method is called Selective Laser Melting (SLM), developed at the Fraunhofer Institute for Laser Technology ILT [2].

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …
