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 () which encloses a portion of the powder layer. The method further has the step of repeating steps (i) and (ii) with each fixation zone () of one layer being in contact with a fixation zone () of an adjacent layer such that a plurality of the fixation zones () together form a coherent hollow sleeve () extending across the layers. The corresponding plurality of powder portions in combination form a contiguous batch () of powder captured in the sleeve. The method facilitates the manufacturing of sintered dental articles.
