Abstract: A flowable liquid formulation for 3D printing is described. The formulation comprises from 0.1 to 25 wt. % radiopaque particles, wherein at least 50% by weight of the particles have a diameter of at most 100 nm. The formulation further comprises monomeric, oligomeric and/or polymeric precursors adapted for polymerization to form a solidified article. Also described is an article (100) formed by 3D printing, the article (100) comprising a first 3D printed region (110) having a first radiopacity and a second 3D printed region (120) having a second radiopacity, wherein the first radiopacity is greater than the second radiopacity. Also described is a method of forming the article (100).

Abstract: A PCB, printed circuit board, structure for forming at least one embedded electronic component. The structure comprises a multi-layer PCB board comprising at least one through-hole via, the via comprising a plurality of electrodes vertically aligned within the via, each electrode comprising a plated ring; and an isolation section separating each of the electrodes.

Abstract: An aperture plate is formed from a palladium nickel alloy comprising about 89% palladium and about 11% nickel. There is a generally fine substantially equiaxed grain microstructure throughout the thickness of the aperture plate. The average grain width (W) is in the range of from 0.2 ?m to 5.0 ?m, in some cases from 0.2 ?m to 2.0 ?m. Because the grain structure is equiaxed (L/W=1) the grain length (L) is the same as the grain width. The improved aperture plate extends the life of nebulisers, eliminates the risk of premature and unpredictable failure of a nebuliser in service, eliminates the risk of product returns from hospitals and patients, and eliminates the possible risk of fragments of the aperture plate breaking free from the nebulizer.
