... The two MEX parameters and their values have been selected by design of experiment method. Three properties of MEX parts, i.e. strength (tensile and three-point bending), surface roughness and the dimensional accuracy, are studied at different build speeds (35 mm/s, 45 mm/s and 55 mm/s) and the layer...

...Donghua Zhao; Weizhong Guo; Baibing Zhang; Feng Gao Purpose The purpose of this study is to analyse the problem of high binder content in sand mould and to solve it. Meanwhile, to increase build speed, especially for heavy casting’s sand mould with a high value in layer height, such as 2 mm...

... the build speed, this paper aims to design and develop a novel AM system with dynamic resolution control capability. Design/methodology/approach A laser projector is adopted in a vat photopolymerization system. The laser projection system has unique properties, including focus-free operation...
