    • Adaptive benchmarking design for additive manufacturing processesPeer reviewedClosed access 

      17 mars 2022, Spitaels, Laurent; Rivière-Lorphèvre, Edouard; DEMARBAIX, Anthoninorcid-id; Ducobu, François, HE Condorcet
      Article 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 ...

    • Development of a novel benchmark artifact for Additive Manufacturing processesPeer reviewedClosed access 

      10 juin 2021, Spitaels, Laurent; Rivière-Lorphèvre, Edouard; DEMARBAIX, Anthoninorcid-id; Ducobu, François, HE Condorcet
      Acte de conférence ou de colloque
      " This article aims to make a review of the existing benchmark artifacts and to summarize the main requirements chosen by authors. From this state of the art, a new benchmark artifact is proposed by adapting an existing one to fulfil its missing characteristics. Measurements possibilities in terms of dimensions are enumerated and organized using ISO 286 dimensional intervals as presented in the ...

    • Dimensional and geometrical performance assessment of two FDM printers using a benchmark artifactPeer reviewedClosed access 

      03 juin 2022, Spitaels, Laurent; Rivière-Lorphèvre, Edouard; DEMARBAIX, Anthoninorcid-id; Thielens, Vincent; Ducobu, François, HE Condorcet
      Acte 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 ...

    • Green Ceramic Machining: Determination of the Recommended Feed Rate for Y-TZP MillingPeer reviewedOpen access 

      01 septembre 2021, DEMARBAIX, Anthoninorcid-id; Mulliez, Marylou; Rivière-Lorphèvre, Edouard; Spitaels, Laurent; Duterte, Charles; Petit, Fabrice; Ducobu, François, HE Condorcet
      Article scientifique
      Abstract : "Manufacturing of advanced ceramic parts exhibiting complex geometries is laborious and expensive. Traditionally, the machining is carried out on a so-called ‘green ceramic’: a compact composed of ceramic powder held with the help of a binder. This difficulty is due not only to the composition of the material, but also to the lack of methods that determine optimal machining parameters. ...

    • Impact of Green Ceramic Hybrid Machining (GCHM) on Reliability and Repeatability of the Properties of Sintered Yttrium-Tetragonal Zirconia Polycrystal PartsPeer reviewedOpen access 

      20 juin 2023, Ducobu, François; DEMARBAIX, Anthoninorcid-id; Rivière-Lorphèvre, Edouard; Spitaels, Laurent; Petit, Fabrice; Preux, Nicolas; Duterte, Charles; Mulliez, Marylou; Lauwers, Bert, HE Condorcet
      Article scientifique
      Abstract : "The innovative Green Ceramic Hybrid Machining (GCHM) process sequentially combines milling with a cutting tool (GCM, Green Ceramic Machining) and laser beam machining (GCLBM) of a ceramic material (black Y-TZP in this study) at the green stage mainly to increase productivity, avoid taper angle limitations of laser beam machining, and obtain micro-features. The study focuses on ...

    • Influence of Conventional Machining on Chemical Finishing of Ti6Al4V Electron Beam Melting PartsPeer reviewedOpen access 

      26 avril 2020, Spitaels, Laurent; Ducobu, François; DEMARBAIX, Anthoninorcid-id; Rivière-Lorphèvre, Edouard; Dehombreux, Pierre, HE Condorcet
      Acte de conférence ou de colloque
      "Additive manufacturing is feeding great hopes for future developments in fields such as aeronautical, biomedical and rapid tooling industrssssies. However, limitations are still restricting its use to make prototypes and hampering mass production. In the case of titanium alloy printing (e.g. Ti6Al4V) with the EBM (Electron Beam Melting) process, the major obstacle to use parts directly after printing ...
