Adaptive benchmarking design for additive manufacturing processes
17 mars 2022, HE CondorcetArticle scientifique"Standards enabling the objective tolerancing and evaluation of dimensional and geometrical performances of additive manufacturing (AM) printers are still missing. The design, printing and measurements of geometrical benchmark test artefacts (GBTA) is the current solution proposed in literature. However, the current GBTA with fixed dimensions cannot cover most of the available printing area of ... -
Chemical etching as a finishing process for electron beam melting (EBM) parts
02 juillet 2019, HE CondorcetActe de conférence ou de colloque"The goal of this research is to analyze the impact of chemical etching on parts produced by electron beam melting. Given that the surface conditions are poor (Ra between 25 to 35 µm), an enhancement of these is asked. Dimensional and surface measurements were realized on conceived parts. Different exposure times were tested. The impact of these times on surface quality was evaluated. To help ... -
Dimensional and geometrical performance assessment of two FDM printers using a benchmark artifact
03 juin 2022, HE CondorcetActe de conférence ou de colloque"In this article, dimensional and geometrical performances of two Fused Deposition Modelling (FDM) printers with Cartesian architecture (Ultimaker S3 and Intamsys FUNMAT HT) are compared using an original benchmark artifact design. Five parts were printed on each printer in ABS. Five other parts were also produced with the Ultimaker S3 in PLA to show the influence of material choice on the printer’s ... -
Investigation into Influence of Tensile Properties When Varying Print Settings of 3D-Printed Polylactic Acid Parts: Numerical Model and Validation
08 août 2024, HE CondorcetArticle scientifiqueAbstract en anglais : "Material Extrusion (MEX), particularly Fused Filament Fabrication (FFF), is the most widespread among the additive manufacturing (AM) technologies. To further its development, understanding the influence of the various printing parameters on the manufactured parts is required. The effects of varying the infill percentage, the number of layers of the top and bottom surfaces ...
