The present disclosure pertains to an improved method and apparatus for compacting a powder layer (10). An exemplary method comprises placing the substrate (12) on a first plate (18), placing a second plate (16) over the powder layer so that the substrate and the powder layer are sandwiched between the first plate and the second plate to form a multilayered structure comprising the first plate, the substrate, the powder layer and the second plate, and calendering the multilayered structure between a top calendering roller (20) and a bottom calendering roller (22). La présente divulgation concerne un procédé et un appareil améliorés permettant de compacter une couche de poudre (10). Un procédé donné à titre d'exemple consiste à placer le substrat (12) sur une première plaque (18), à placer une seconde plaque (16) sur la couche de poudre de telle sorte que le substrat et la couche de poudre sont pris en sandwich entre la première plaque et la seconde plaque pour former une structure multicouche comprenant la première plaque, le substrat, la couche de poudre et la seconde plaque, et à calandrer la structure multicouche entre un rouleau de calandrage supérieur (20) et un rouleau de calandrage inférieur (22).
