"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 ...

"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 ...

"The invention relates to an apparatus configured to detect and measure in real time an electrical response from an electrical component exposed to ionizing radiation."

"This paper proposes a portable 3D printed test set-up allowing to realize this transient measurement while ensuring no interaction with the outside world. Moreover the setup proposes a variation of distance to favor or not the interaction of the semiconductor with the ionizing radiation source. The main advantages of the proposed 3D setup is its adaptability to any kind of radiation source geometry ...

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 ...
