“…Zhou et al [47] as well as others [39,40] have used a similar, semi-empirical approach by the Taguchi experimental design techniques and process the results with the response surface methodology and analysis of variance (ANOVA) methods, to investigate into the optimal parameters (including layer thickness, hatch spacing, hatch style, hatch overcure, blade gap, position on the build plane) of the platform of the SLA process. The issue has also been experimentally modelled, by [36][37][38]89] having presented experimental studies on the dimensional accuracy of the SLA parts and the associated process parameters. A process planning method was developed by Lynn et al [41,42] and was further improved by West et al [34] in order to develop response surface models for the evaluation of the SLA parts' accuracy.…”

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.

“…Many attempts [4][5][6][7][8][9][10][11][12][13][14][15][16][17] have been made to decide a suitable part deposition orientation using different criteria like part accuracy, surface quality, build time, volume of support structure and cost. Dimensional accuracy was measured in terms of weight factors determined experimentally for various types of surfaces in Stereolithography (SL) [5].…”

“…Alexander et al [7] requires support structure, the build direction is often confined with the planar (flat) surfaces of the object [6,11,12] as base. Xu et al [13] proposed the selection of an optimum building direction considering the differences of building inaccuracy, surface finish, and manufacturing time and cost for multiple additive manufacturing processes.…”
