“…The head is moved up vertically as each layer is completed. This technique is equivalent to several trademarked techniques, such as DMD, LPD and SLC [18]. Compared to processes that use powder beds, such as SLM, objects created with this technology can be substantially larger, even up to several meters long; however, the accuracy and surface quality are usually lower.…”

Additive manufacturing is a technology rapidly expanding on a number of industrial sectors. It provides design freedom and environmental/ecological advantages. It transforms essentially design files to fully functional products. However, it is still hampered by low productivity, poor quality and uncertainty of final part mechanical properties. The root cause of undesired effects lies in the control aspects of the process. Optimization is difficult due to limited modelling approaches. Physical phenomena associated with additive manufacturing processes are complex, including melting/ solidification and vaporization, heat and mass transfer etc. The goal of the current study is to map available additive manufacturing methods based on their process mechanisms, review modelling approaches based on modelling methods and identify research gaps. Later sections of the study review implications for closed-loop control of the process.

“…SLS 1 , DMLS 2 and SLM 3 belong to the family of additive manufacturing technologies (we will use term Metal Laser Sintering technologies or MLS abbreviation further in text due to simplicity) that build the geometry of the part by solidification of metal powders using laser power Khaing, 2001).What particularly distinguishes them from other additive technologies is the possibility to produce fully functional metal parts. This feature as well as the ability to create highly complex geometrical shapes, which are often not possible, or at least very difficult to make by conventional manufacturing processes, promote these technologies as perfect candidates for moulding and rapid tooling (RT) (Simchi et al, 2003;Pessard et al 2008).…”

“…Laser fuses the metal powder into a solid part. After the layer is finished a build platform lowers a layer thickness and a wiper blade is used to spread new powder layer over the build platform and the process then starts from beginning [6].…”
