Abstract: A method of making a dental article, has steps of (i) providing a layer of sinter powder, (ii) providing a solidifiable binder to form a circumferential fixation zone (114) which encloses a portion of the powder layer. The method further has the step of repeating steps (i) and (ii) with each fixation zone (114) of one layer being in contact with a fixation zone (114) of an adjacent layer such that a plurality of the fixation zones (114) together form a coherent hollow sleeve (116) extending across the layers. The corresponding plurality of powder portions in combination form a contiguous batch (118) of powder captured in the sleeve. The method facilitates the manufacturing of sintered dental articles.
