Journal ArticleDOI
An investigation of surface quality characteristics of 3D printed PLA plates cut by CO2 laser using experimental design
John Kechagias,Konstantinos Ninikas,Markos Petousis,Nectarios Vidakis,Nikolaos M. Vaxevanidis +4 more
TL;DR: In this article, mean surface roughness and angle of the kerf during laser processing of 3D-printed polylactic acid (PLA) plates with 4.00 mm in thickness were investigated.
Journal ArticleDOI
Heat recovery from air in underground transport tunnels
TL;DR: In this paper, the authors conducted an annual survey of air flow, air temperature and relative humidity at thirty different points within the Glasgow subway network and found relatively stable temperatures and sufficient air movement inside the twin tunnels.
Journal ArticleDOI
Surface characteristics investigation of 3D-printed PET-G plates during CO2 laser cutting
John Kechagias,Nikolaos A. Fountas,Konstantinos Ninikas,Markos Petousis,Nectarios Vidakis,Nikolaos M. Vaxevanidis +5 more
TL;DR: In this paper, the influence of the stand-off distance (SoD), laser speed (LS) and laser power (LP) on kerf geometry (upper width Wu, down width Wd and kerf angle KA) and mean surface roug
Journal ArticleDOI
A robust methodology for optimizing the topology and the learning parameters of an ANN for accurate predictions of laser-cut edges surface roughness
John Kechagias,John Kechagias,Aristeidis Tsiolikas,Markos Petousis,Konstantinos Ninikas,Nectarios Vidakis,Lazaros Tzounis +6 more
TL;DR: A methodology is presented for the optimization of an FFBP-NN and the application of the Taguchi Design of Experiments (TDE) to predict the surface roughness in various cut depths during laser cutting of thin thermoplastic plates.
Journal ArticleDOI
Laser cutting of 3D printed acrylonitrile butadiene styrene plates for dimensional and surface roughness optimization
TL;DR: In this article, the effects on the dimensional accuracy and the surface roughness of process parameters, during low power CO2 laser cutting (LC) of thin acrylonitrile butadiene styrene (ABS) plates manufactured with the FFF process were investigated.
